This HTML page contains the basic install docs that can be found on http://purl.net/wiki/moin/MoinMoin/InstallDocs. It contains all necessary information to get your wiki up and running, even without being online. If you have a permanent internet connection, you might want to browse the docs on the HelpOnInstalling page, which might contain more up-to-date information.

After following the procedures on this page, you should have a working wiki and can browse the rest of the online docs there.

How to install your own MoinMoin Wiki

This page describes the installation procedure applying to MoinMoin:MoinMoin version 0.11 and up. In the next section, there is a list of real-world Installation Scenarios that help you to understand how to apply the instructions in different environments.

Basic Installation explains the "setup.py" step of the installation in more detail. This applies equally to all scenarios, and you should read it before trying a live installation.

Trouble-shooting helps with fixing any general problems you might encounter, which apply to any installation platform.

After a successful installation, you might want to read more about configuration and other options that you, as the wiki administrator, can set up. MoinMoin:HelpOnAdministration contains links to pages that cover these topics. Especially, the MoinMoin:HelpOnConfiguration and MoinMoin:HelpOnUpdating pages provide additional information regarding wiki setup and maintenance. MoinMoin:MoinMoinWinCvs and MoinMoin:MoinMoinUnixCvs describe how to run your wiki using the current development version from the MoinMoin:SourceForge CVS repository.

Sample Installation Scenarios

The following links lead you to concrete examples of installation sessions, showing the commands used and explaining what they do. It is highly recommended that you first read the general information on installing (especially the next section of this page) before choosing an installation scenario that best fits your intended use of MoinMoin:MoinMoin.

Basic Installation

Before you can integrate MoinMoin into your web environment, you have to do the basic installation using the standard Python distutils mechanism. We'll explain the usual steps you need to take to do this. For more details on the distutils installation process, consult the Installing Python Modules document of your Python manual.

  • /!\ NOTE: You will need the Python Development package installed on UNIX systems for distutils to work correctly.

The first step is to unpack the distribution archive, which you have done already when you loaded this instructions from your disk. If you read this on the web, the distribution comes in a versioned ZIP or TAR archive, which you can unpack in the usual ways, into a temporary directory (/tmp on UNIX, C:\TEMP on Windows). The distribution archive will always unpack into a directory named moin-<version>, for example moin-0.11. To download the distribution archive, go to the download area.

After unpacking, to install into a specific directory (C:\moin in our example), call setup.py after changing your current directory to the distribution directory. The following commands can be used to complete theses steps:

  •     unzip moin-0.11.zip
        cd moin-0.11
        python setup.py --quiet install --prefix=C:\moin

This creates the following directories in "C:\moin" (note that on a UNIX system, the directory layout will be slightly different):

  •     MoinMoin
        MoinMoin/action
        MoinMoin/formatter
        MoinMoin/i18n
        MoinMoin/macro
        MoinMoin/parser
        MoinMoin/py15
        MoinMoin/scripts
        MoinMoin/support
        MoinMoin/twisted
        MoinMoin/webapi
        Scripts
        share
        share/moin
        share/moin/cgi-bin
        share/moin/data
        share/moin/data/backup
        share/moin/data/cache
        share/moin/data/pages
        share/moin/data/plugin
        share/moin/data/plugin/action
        share/moin/data/plugin/macro
        share/moin/data/text
        share/moin/data/user
        share/moin/htdocs
        share/moin/htdocs/css
        share/moin/htdocs/img

You will likely see the following warning:

  • warning: install: modules installed to 'C:\moin\', which is not in Python's module search path (sys.path) -- you'll have to change the search path yourself

This means exactly what it says, you need to add your install directory to the search path of Python. There are several ways to do this:

Environment variable

Change PYTHONPATH in a way that is persistent (/etc/profile.d on UNIX, AUTOEXEC.BAT on W9x, the Properties item in the context menu of My Computer on NT4 and W2K)

Apache "httpd.conf"

Use the SetEnv directive to set PYTHONPATH to a suitable value, for example:

    SetEnv PYTHONPATH "C:\moin"
"moin.cgi"
Directly add your installation directory to

the CGI driver script, like this:

    import sys
    sys.path.append('C:/moin')

If you use the following default installation command, MoinMoin will be installed to the Python directory:

  •     python setup.py --quiet install

You won't need to change your PYTHONPATH then, but depending on your system environment you might not be able to use that command, especially when you are not the root user on a UNIX system. If you don't know where your Python directory is, this command will tell you:

  •     python -c "import sys; print sys.prefix"

The directory structure we showed above will then be created in that directory. If you're interested in the exact list of files that are installed, use the --record option of distutils.



Trouble-shooting

Built-in test

There's a built-in diagnostic mode that's useful when doing an install; just append "?test" to the URL of your wiki:

lynx --dump http://`hostname`/mywiki?test

If you see an import error here, but "python -c "import MoinMoin"" works, it's likely a result of missing file permissions or a wrong PYTHONPATH setting within the web server environment.



UNIX Installation

Index

Installation when you are root or the webmaster

When you are root or the webmaster on the host you want to install MoinMoin on, you can place the software in a "standard" location, and also better integrate MoinMoin into your webserver. Especially, you can use a "nice" base URL that does not include "cgi-bin" or "moin.cgi" at all.

Most GNU/Linux distributions come with Apache pre-installed. In the following description, we assume the file system layout of a SuSE 7.0 system, that is:

  • /etc/httpd/httpd.conf - the main httpd configuration file

  • /var/log/httpd/error_log - log containing error messages

Installing MoinMoin

Before creating a wiki instance, you have to download and install the basic MoinMoin software. We assume you already have downloaded the distribution archive to "/tmp" 1.

Open a shell and enter the following commands:

cd /tmp
tar xfz moin-0.11.tgz
cd moin-0.11
python setup.py install --record=install.log

This will install all necessary files into the sys.prefix directory of your Python interpreter (usually either "/usr" or "/usr/local"), and create a "install.log" file listing all the files that are created there. The command "python -c 'import sys; print sys.prefix'" will tell you where your Python interpreter is installed, we assume "/usr/local" here.

  1. If you want to install the current development version from CVS, replace "/tmp" with your "moin" working directory. (1)

Creating a wiki instance

You could run your wiki directly using the sample wiki created in "/usr/local/share/moin", but this is not recommended for two reasons:

  1. updating your wiki is more complicated and more dangerous.
  2. creating a second wiki instance, even if you currently don't plan for one, is much easier.

We need to know what user and group your Apache server runs on, so issue this command:

  • jh@localhost:~ > egrep "^User|^Group" /etc/httpd/httpd.conf
    User wwwrun
    Group nogroup

This shows a typical result "wwwrun.nogroup", which we will use later on.

To create an instance named "mywiki", enter these commands on a root shell prompt:

cd /usr/local/share/moin
mkdir mywiki
cp -r data mywiki
cp cgi-bin/* mywiki
chown -R wwwrun.nogroup mywiki
chmod a+rx mywiki/*.cgi

"mywiki" is the name of your wiki instance, you might want to chose a different name best fitting the intended use of this instance; just don't name it simply "wiki", because that would result in problems later on.

Then, append these lines to "/etc/httpd/httpd.conf":

Alias /wiki/ "/usr/local/share/moin/htdocs/"
ScriptAlias /mywiki "/usr/local/share/moin/mywiki/moin.cgi"

The first line you only need once; the second line is needed once for each wiki instance (of course, each one with another wiki name and path).

That is all, restart your Apache server ("/etc/rc.d/apache restart" on SuSE) and try to access your new-born wiki with the URL "http://127.0.0.1/mywiki/". You should see the FrontPage, try to edit and save it, and if that works, see if your edit is reflected on the RecentChanges page.

Finally, edit "moin_config.py" and at least change "sitename" and "logo_url" to some personal values:

sitename = 'My Wiki'
logo_url = '/images/mywiki-logo.gif'

For a personal or intranet installation, you'll normally also add the line

allowed_actions = ['DeletePage', 'AttachFile']

Troubleshooting

The first thing to do when your wiki does not work as expected is to issue the command "tail /var/log/httpd/error_log" to display the most recent errors. Usually, you will get a hint on what went wrong, like missing file system permissions. Also, always consult the HelpOnInstalling/TroubleShooting page for further hints on your problem.

Dueling Pythons

The most common problem you might encounter is when you have Python 1.5.2 installed into "/usr", and a newer Python distribution into "/usr/local"; this is typical for GNU/Linux distributions that still come bundled with version 1.5.2 of Python.

In that case, if you enter "python" on your prompt, you will usually get the more recent Python interpreter, because "/usr/local/bin" is in your PATH. The situation is different in your webserver environment, and thus you might have to change the bang path of "moin.cgi", like this:

"""
    MoinMoin - CGI Driver Script
...
"""

Distutils does not work

If you have problems with the distutils install step, note that you need to have the Python development package installed on some Unix distributions. On Mandrake, you need to "rpm -i python-devel-2.1.1-3mdk.i586.rpm".

Missing file permissions

If you are root, the installed files may be readable only by root, but they must also be readable by the web server before the wiki will work. This includes both the Python modules and the site itself. For the data directory, the web server also needs write access. To fix this, first find out where the Python module directory is; look in install.log, or run the command:

python -c "import sys; print '%s/lib/python%s/site-packages' % ( sys.prefix, sys.version[:3] )"

For the example below, we'll assume that the Python module directory is /usr/local/lib/python2.1/site-packages. Make the files world-readable using the following commands:

cd /usr/local
chmod -R a+rX lib/python2.1/site-packages/MoinMoin share/moin

/!\ Note that by making everything under /usr/local/share/moin world-readable, local users can read the files containing your wiki. You don't really need to do that, since the mywiki directory is owned by the webserver. If you don't want that, you do a "chmod -R o-rwx share/moin/mywiki" after the above commands.

Installation into your home directory

Installation into your shell account's home directory is typically used on a host shared by many users and where you are not the root user. This usually implies that you cannot change the httpd.conf file, and also you cannot copy files into the machine's cgi-bin and htdocs directories. For this situation, Apache includes the UserDir directive, which maps all URLs that start with "/~username" to a directory in your home directory, where you have write permissions and thus can install MoinMoin.

Making sure /~username URLs work

This kind of setup can only work if your webmaster has configured the host's Apache server so that the UserDir mechanism works. Here's how to check for this:

  • jh@localhost:~ > ls -ld public_html
    drwxr-xr-x   2 jh       users          35 Jan 31 00:29 public_html

If this does not show a listing like above, then you might need to create the public_htmldirectory. Note that this directory must be readable (r-x) by the web server.

  • jh@localhost:~ > lynx -error_file=/dev/stderr -dump http://localhost/~jh/ >/dev/null
       URL=http://localhost/~jh/ (GET)
    STATUS=HTTP/1.1 200 OK

You see here that we get a "200 OK" status response, which means that you can access your public_html area. If it does not work, you will probably get a "403 Forbidden" or a "404 Not Found" response. The first one normally indicates that you need to fix the permissions of your home directory (~) or your ~/public_html. But we also need to be able to execute CGI scripts, so we test that, too.

  • jh@localhost:~ > cat >~/public_html/test.cgi
    #!/bin/sh
    echo Content-Type: text/plain
    echo
    echo IT WORKS
    <CTRL-D>
    jh@localhost:~ > chmod a+rx ~/public_html/test.cgi
    jh@localhost:~ > lynx -dump http://localhost/~jh/test.cgi
    IT WORKS

If you see anything else than "IT WORKS", then you are not allowed to execute CGI scripts. How you get that to work is not in the scope of this description, ask your webmaster!

A working Python installation, and a working diff command is also assumed.

  • jh@localhost:~ > python -V
    Python 2.1
    jh@localhost:~ > diff --version
    diff - GNU diffutils version 2.7

(!) The command line examples show your input in bold typewriter, and the sample output in plain typewriter. The examples use "jh" as the user's name, which means you have to replace your own one whereever "jh" appears. The same is true for version numbers (0.11) and download URLs.

Getting the distribution archive and doing the basic installation

The following commands will fetch and install the nightly CVS tarball, i.e. the current development version. To get the official distribution version, use an appropriate URL.

  • mkdir ~/tmp
    cd ~/tmp
    wget http://moin.sf.net/files/moin-0.11.tar.gz
    tar xfz moin-0.11.tar.gz
    cd moin-0.11
    python setup.py --quiet install --home=$HOME --record=install.log

This will install the MoinMoin software into the directories "~/lib/python/MoinMoin", "~/bin", and "~/share/moin". You'll find a detailed file list in "install.log".

Setting up a wiki instance

The next step is to create a copy of the wiki data and the config file.

  • mkdir ~/wiki
    cd ~/wiki
    cp ~/share/moin/cgi-bin/moin_config.py .
    cp -r ~/share/moin/data .
    chmod -R o+rwX data
    vi moin_config.py

The last command starts the editor, you need to at least change the "data_dir" and "url_prefix" config values, as you can see in the following diff:

  • @@ -28,4 +28,4 @@
     interwikiname = None
    -data_dir = './data/'
    -url_prefix = '/wiki'
    +data_dir = '/home/jh/wiki/data/'
    +url_prefix = '/~jh/wiki'
     logo_url = url_prefix + '/img/moinmoin.gif'

Setting up public_html and testing the installation

Now we create the public part of the wiki, which is directly accessible by the web browser.

  • cd ~/public_html
    cp -r ~/share/moin/htdocs wiki
    cp ~/share/moin/cgi-bin/*.cgi .
    chmod a+rx *.cgi

To be able to execute the CGI script in your home directory, you need to extend Python's path within that script, and possibly adapt the bang path (that is the first line of the script). So, change "moin.cgi" similarly to this diff:

  • @@ -1,2 +1,2 @@
    -#! /usr/bin/env python
    +#! /usr/local/bin/python2.1
    
    @@ -11,4 +11,4 @@
    
    -#import sys
    -#sys.path.append('/usr/local/home/USERNAME/lib/python')
    +import sys
    +sys.path.extend(['/home/jh/wiki', '/home/jh/lib/python'])

Finally, you can test your wiki installation by running the MoinMoin CGI Diagnosis:

  • lynx -dump http://localhost/~jh/moin.cgi?test

And now, your wiki should work and is available at the URL "http://localhost/~jh/moin.cgi". Conclude your tests by editing and saving the FrontPage and checking out RecentChanges, which should reflect that edit.

Many users prefer to install software products in a folder other than the installation default. Python typically changes the default installation folder name with each point release, and Apache has changed the default installation folder name with the release of version 2. Instead of enumerating all the possibilities at each step, this procedure will use the Reference name in the table below as the installed location for each product. Substitute your real installation location when editing configuration files and entering commands.

This installation procedure was tested with Apache 1.3.26 and Apache 2.0.44 for Windows running on Windows/ME, and using Python 2.1, 2.2 and 2.3a.

Preparation

MSI Installer

Installation of Apache and one alternative distribution of Python require the Microsoft MSI Installer. The latest version, 2.0, was released in September of 2001. You will know you don't have the correct version if you receive errors after double-clicking on a file name ending in .msi. To get the latest version, go to http://www.microsoft.com/, search for msi installer, and follow the instructions. There are two versions, one for Windows/ME, 98, and 95; and another for Windows 2000 and NT. Windows/XP has the 2.0 version and requires no update.

WinZip, unzip, ...

MoinMoin is distributed in a zipped format for Windows users. Some versions of Windows are distributed with an unzip utility, many other Windows users rely on WinZip, a popular shareware program, available from http://www.winzip.com/. There are many alternative compression utilities that are compatible with the .zip format. Since the .zip format is so commonly used for downloaded files, this procedure assumes you have a zip utility and know how to use it. If not, download WinZip or an alternative and review the instructions.

WinCVS

WinCVS is a GUI front end which can be used to retrieve MoinMoin module updates soon after they are committed to the SourceForge CVS system. Most users should never need to use this. If you really need a new MoinMoin feature that has just been committed to CVS now, and don't mind testing fresh code, then you can read more about it in MoinMoin:MoinMoinWinCvs.

You can install MoinMoin directly from your \CVSRoot\moin folder, just follow the installation instructions below as if you unzipped the current release into that folder. Note there is a potential problem if you instruct WinCVS to mark files with the Read-Only attribute. The setup program will not work correctly the second time you try to reinstall MoinMoin from \CVSRoot\moin because it will fail while attempting to overwrite the Read-Only files from the prior installation.

Installing Apache

To obtain the latest version of Apache, go to http://www.apache.org/, and click on the link to HTTP Server. Find the link to download the Win32 Binary (MSI Installer) version. Read the Apache documentation to determine the correct installation procedure for your situation. Questions and problems with the Apache installation process should be resolved thru use of the resources provided by the Apache organization. Be sure your webserver runs correctly before proceeding.

Warning: the procedure described above tends to trivialize the installation of the Apache web server. Apache can be installed and running on your PC in a very few minutes with only a cursory examination of the Apache documentation. Before you undertake the installation of any web server that can be accessed through the internet, you should exercise a controlled level of paranoia and assess the potential damage that may be caused by hackers accessing or destroying sensitive data. This should include not only the all data which resides on the PC which will host the Apache web server, but all other PCs on the local LAN which participate in any form of file sharing.

Windows/ME, 98SE, 98, 95, and probably NT should be considered inappropriate hosts for any Apache web server that can be accessed via the internet. Use either Windows/2000 or XP and install all security patches available for your operating system.

Do not let the above discourage you from installing MoinMoin. Most of the internet activity probing your system for weaknesses will be from virus infected Windows/NT systems running IIS whose owners have neglected to apply available security patches. The starting Apache configuration is secure and you will not have a problem provided you:

  • Regularly review and apply security patches for your installed software.
  • Understand the ramifications of any changes you make to the Apache config files.
  • Regularly review the Apache logs for suspicious activity.
  • Regularly take backups of your data.

Installing Python

There are currently two different distributions of Python available for Windows. The normal Python distribution is available from http://www.python.org. This is distributed as a windows executable (.exe) file.

An alternative distribution called ActivePython is available from http://www.activestate.com. This distribution uses the MSI Installer and contains some tools specific to the Windows operating system and a popular Windows IDE called Pythonwin. ActivePython is available for free; an email address is requested (but not required) before downloading.

MoinMoin will work with either distribution, but requires Python release 2.0 or later. Download and install the distribution of your choice. Questions and problems dealing with the Python installation process should be resolved through the use of resources provided by Python.org or ActiveState. Be sure your Python installation is correct before proceeding.

Installing MoinMoin

Download the current version of MoinMoin from http://moin.sourceforge.net/ into C:\TEMP or an alternative location. Be sure to choose the version in the .zip format rather than the .tgz format.

Using your favorite unzip utility discussed above, unzip the MoinMoin distribution file into the same folder. You should then have a folder C:\TEMP\moin-x.x where "x.x" is the current release number. This folder will contain a setup.py file in addition to several other files and subfolders.

Open an MS-DOS or console window and enter the commands:

C:
cd \TEMP\moin-x.x
C:\Python\python setup.py install --record=install.log

The above commands will add MoinMoin to your C:\Python installation and create an install.log file in C:\temp\moin-x.x listing all the copied files. You may use Windows Explorer to examine the newly created folders within C:\Python. You should find a C:\Python\share\moin folder with subfolders cgi-bin, data, and htdocs. If you have Python 2.0 or 2.1 you will find a folder C:\Python\MoinMoin, but with Python 2.2 and later it will be C:\Python\Lib\site-packages\MoinMoin. The MoinMoin folder contains many Python scripts and several subfolders.

You are now ready to create a wiki instance.

Creating a Wiki Instance

It is a good practice to try to keep all of your personal or site specific data under a few root folders. This way you can easily backup your important data on a regular basis without having to waste time either backing up static files or picking out dozens of important folders scattered throughout your folder structure. You should avoid placing your wiki data under the C:\Python folder so that you can later upgrade Python or MoinMoin without accidentally overwriting or deleting your wiki data. For the same reason, you probably don't want to place your wiki data within the C:\Apache folder. The default personal folder under many Windows versions is called C:\My Documents.

Choose a location appropriate for you; the following instructions assume you will be creating one or more wiki instances in C:\Moin\ and the first wiki instance will be named mywiki.

You may replace the name mywiki with almost any name you wish, but do not use wiki because that is used by MoinMoin for loading standard images and style sheets. Although this can be changed later, the plan is that the name you choose for mywiki will become part of the url used to access your site, e.g. http://myorganization.org/mywiki/FrontPage.

Start an MS-DOS or console window and enter the commands below. This will create a clone of the MoinMoin wiki in the mywiki folder. The wikidata folder will be used later for mywiki customization, such as logos and style sheets.

cd C:\
md Moin
md Moin\wikidata
md Moin\mywiki
md Moin\mywiki\data
cd \Python\share\moin
xcopy data        C:\Moin\mywiki\data /E
copy  cgi-bin\*.* C:\Moin\mywiki\*.*

If your server is going to run multiple wikis, you need to create additional clones. The commands below will create mywiki2. The wikidata folder created above can contain custom logos and style sheets for all your wikis.

cd C:\
md Moin\mywiki2
md Moin\mywiki2\data
cd \Python\share\moin
xcopy data        C:\Moin\mywiki2\data /E
copy  cgi-bin\*.* C:\Moin\mywiki2\*.*

Use your editor to edit the file C:\Moin\mywiki\moin.cgi. Change the first line (the shebang statement) to point to your local Python executable program. Note the forward slashes -- Apache uses the Unix convention for folder separators. This tells Apache the moin.cgi file is an executable script that will be interpreted by a program to be loaded from C:/Python/python.

The next step is to tell Apache that is has more work to do. Use your editor to append the following lines to C:\Apache\conf\httpd.conf.

Alias       /wiki/     "C:/Python/share/moin/htdocs/"
Alias       /wikidata/ "C:/Moin/wikidata"
ScriptAlias /mywiki    "C:/Moin/mywiki/moin.cgi"

The Alias lines for wiki and wikidata above instructs Apache to serve GIF images, style sheets, etc. from the specified folders and subfolders. The ScriptAlias line is needed once for each wiki instance, so if you have multiple wikis, repeat the statement using mywiki2, mywiki3, etc. The ScriptAlias statement instructs Apache to execute scripts from the specified folder. See the Apache docs for a complete explanation.

Test your changes by restarting your Apache server and try to access your newborn wiki with the URL http://127.0.0.1/mywiki. You should see the FrontPage, try to edit and save it, and if that works, verify your edit is reflected on the RecentChanges page.

Finally, edit C:\Moin\mywiki\moin_config.py and at least change sitename to the name of your wiki:

sitename = 'My Wiki'

If you want to replace the MoinMoin logo with one named mywikilogo.gif, copy your logo to C:\Moin\wikidata and change logo_url in moin_config.py as follows:

logo_url = '/wikidata/mywikilogo.gif'

For a personal or intranet installation, you'll normally also add this line to moin_config.py:

allowed_actions = ['DeletePage', 'AttachFile']

Additional configuration details can be found in HelpOnConfiguration.

And now, it is up to you and your user community to transform your wiki into an informative and useful tool. You will probably want to retain most of the HelpOn~ pages dealing with editing, delete those pages with irrelevant information (like this page, don't let your users or boss know how easy it was to install MoinMoin ;) ), and rewrite the FrontPage to introduce your wiki topic.

Troubleshooting

The first place to look for clues when the unexpected happens is to try changing your url to: http://127.0.0.1/mywiki?test. If Apache can find and execute the module C:/Moin/mywiki/moin.cgi, a page of diagnostics titled MoinMoin CGI Diagnosis will be displayed. Check the output for error messages.

The second place to look for is C:\Apache\logs\error.log. The following are common errors grouped by the message displayed by your browser.

Internal Server Error

If the Apache log shows a message "The system cannot find the file specified." then a possibility is the shebang statement in moin.cgi is incorrect.

If the Apache log shows a different error message, then the MoinMoin Python scripts may be abending. To determine the cause, you could try temporarily renaming moin.cgi to moin.py, loading moin.py with the Python idle IDE and executing it to determine if there are any error messages.

Not Found

If the Apache error log shows the message "File does not exist: C:/Apache/htdocs/mywiki", the ScriptAlias statement in httpd.conf may be incorrect.

The Page Cannot be found

If the Apache error log shows the message "File does not exist: C:/Apache/htdocs/????", you may have mistyped the url "http://127.0.0.1/mywiki" into your browser.

FrontPage Loads Without Icons

If the Apache Error log shows many error messages "File does not exist: C:/Apache/htdocs/wiki", then the Alias statement in httpd.conf may be incorrect.



Windows Installation using IIS

Index

Requirements

Before you install MoinMoin:MoinMoin, make sure you have the necessary infra-structure in place, namely the Internet Information Services webserver (any version should be OK), and a Python installation (version 2.0 or higher is recommended, don't run 1.5.2 without a compelling reason).

In the following description, we assume that you have installed or will install things to these locations:

  • IIS to its default location
  • C:\Python - the Python interpreter

  • C:\Moin - MoinMoin itself

Quite often, you might want to install things elsewhere, which is no problem at all; you just have to adapt any paths that appear in a command or config file to the locations you have chosen.

This installation procedure was tested with IIS 5 for Windows running on Windows 2000sp2, and using Python 2.2.

Preparation

Installing IIS

You currently need an external webserver to run MoinMoin.

From Microsoft: (http://www.microsoft.com/windows2000/en/server/iis/)

  • To install IIS, add components, or remove components: Click Start, point to Settings, click Control Panel and start the Add/Remove Programs application. Select Configure Windows, click the Components button, and then follow the on-screen instructions to install, remove, or add components to IIS.

Make sure that your webserver runs without problems before you start to install MoinMoin; problems with your webserver installation are not in the scope of this document.

Installing Python

Download Python 2.1.2 and install it. Python installation is done via a standard Windows installer program.

Installing MoinMoin

Before creating a wiki instance, you have to download and install the basic MoinMoin software. We assume you already have downloaded the distribution archive to the "C:\TEMP" directory1.

Open a console window and enter the following commands:

C:
cd \temp
unzip moin-0.11.zip
cd moin-0.11
python setup.py install --prefix=C:\Moin --record=install.log

This will install all necessary files to the "C:\Moin" directory, and create a "install.log" file listing all the files that are created there.

  1. If you want to install the current development version from CVS, replace "C:\TEMP" with your "moin" working directory. (1)

Creating a Wiki Instance

You could run your wiki directly using the sample wiki created in "C:\Moin", but this is not recommended for two reasons:

  1. updating your wiki is more complicated and more dangerous.
  2. creating a second wiki instance, even if you currently don't plan for one, is much easier.

So, enter these commands in a console window:

cd \Moin
md mywiki
md mywiki\data
xcopy share\moin\data mywiki\data /E
copy share\moin\cgi-bin mywiki
copy share\moin\htdocs\index.html mywiki\default.htm

"mywiki" is the name of your wiki instance, you might want to chose a different name best fitting the intended use of this instance; just don't name it simply "wiki", because that would result in problems later on.

We have to make sure that moin.cgi can find the MoinMoin directory, so that "import MoinMoin" will work. You can either setup a PYTHONPATH environment variable which includes the installation path, but sometimes it can be tricky to make sure the variable will be set in the CGI environment. The easiest way to make sure MoinMoin can be imported is to append to sys.path within moin.cgi.

You can change the first two lines of code in moin.cgi to something like this:

   1 import sys
   2 sys.path.append(r'C:\Moin')

Notice that we're pointing to the directory which contains the MoinMoin directory, not the directory itself.

  • /!\ Python 2.2: Python 2.2 changed the installation layout. Because of this, you have to change the line of code given above to "sys.path.append(r'C:\Moin\Lib\site-packages')".

Next, you'll need to create two virtual directories in IIS. One for the shared data, and one for this specific wiki instance.

Go to Control Panel => Administrative Tools => Internet Information Service. Open up the tree to Default Web Site.

Right click on Default Web Site and choose New => Virtual directory. This will bring up a wizard with the manditory useless first screen, hit next. Enter "wiki" for the alias name and hit next. Browse to "C:\Moin\share\moin\htdocs" and hit next. Leave the Access permissions at their defaults and hit next. And now you're done, hit finish!

Now follow the same steps, but set the alias to "mywiki" and the path to "C:\Moin\mywiki".

Now you need to setup the 'mywiki' alias so that it will run Python to interpret .cgi files. Right click on your new 'mywiki' alias and choose Properties. On the first tab (Virtual Directory), click the Configuration button. The first tab is the App Mappings tab, which defines which programs to use for each file exetension. Click Add. Browse to your python.exe (probably something like c:\pythonXX\python.exe). Then add -u %s %s after the Python executable path. The Executable line will look something like this: C:\Python22\python.exe -u %s %s. In the Extension box enter .cgi with the begining period. Confirm that the Check that file exists option is not checked (if it is, MoinMoin won't be able to display sub pages). Ok, you're done with the alias configuration, click OK several times to get back out of all the dialog boxes.

If you add another wiki instance, you'll only need to setup the reference to its folder, they can safely share the "wiki" alias which points to static files only.

That is all, try to access your new-born wiki with the URL "http://127.0.0.1/mywiki/". You should see the FrontPage, try to edit and save it, and if that works, see if your edit is reflected on the RecentChanges page.

Finally, edit "moin_config.py" and at least change "sitename" and "logo_url" to some personal values:

sitename = 'My Wiki'
logo_url = '/images/mywiki-logo.gif'

For a personal or intranet installation, you'll normally also add the line

allowed_actions = ['DeletePage', 'AttachFile']

Troubleshooting

If you see an error like "ImportError: No module named MoinMoin", it means that python cannot find MoinMoin. See above for how to set your PYTHONPATH or add to sys.path.
