Before you install MoinMoin, make sure you have the necessary infrastructure in place, namely the Internet Information Services webserver (any version should be OK), and a Python installation (at least version 2.3 is required, the latest python release is recommended).

These instructions make the basic assumption that you will have these components installed in their default locations. In reality, you'll probably have them installed elsewhere (on "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 confusion and problems later on.

We have to make sure that moin.cgi can find the MoinMoin directory, so that "import MoinMoin" will work. 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 #!python
   2 import sys
   3 sys.path.append('C:/Moin/Lib/site-packages')

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

Configuring IIS

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

Configuring IIS 5.0 and above

  1. Open Internet Services Manager (Start > Settings > Control Panels > Administrative Tools > ...). Open up the tree to Default Web Site.

  2. Right click on Default Web Site and choose New > Virtual directory.

    1. This will bring up a wizard with the mandatory useless first screen, hit next.

    2. Enter "moin_static182" (assuming you are installing moin 1.8.2) for the alias name, hit next.

    3. Browse to "C:\Moin\share\moin\htdocs", hit next.

    4. Leave the Access permissions at their defaults, hit next.

    5. And now you're done, hit finish!

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

  4. Use IIS Admin to remove permissions to read the data directory:

    1. expand the "mywiki" node

    2. right click on data

    3. select Properties

    4. and uncheck Read.

    5. Repeat these steps with the underlay directory.

  5. Now you need to setup the 'mywiki' alias so that it will run Python to interpret .cgi files.

    1. On Windows Server 2003, click the Create button under Application Settings to create an application space.

    2. Right-click on your new 'mywiki' alias and choose Properties. On the first tab (Virtual Directory), click the Configuration button.

    3. The first tab is the App Mappings tab, which defines which programs to use for each file extension.

    4. Click Add. Browse to your python.exe (probably something like c:\pythonXX\python.exe).

    5. 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 beginning period.

    6. Make sure that the Check that file exists option is not checked (if it is, MoinMoin won't be able to display sub pages).

    7. Ok, you're done with the alias configuration, click OK several times to get back out of all the dialog boxes.

  6. 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.

IIS 6.0 (Windows Server 2003)

The instructions below also apply to IIS 6.0 but the more aggressive security settings in newer version of IIS disallow the usage of unknown CGI extensions. That means you will always get a 404 error unless you do this:

  1. Open IIS Manager (Start > Programs > Administrative Tools > IIS Manager).

  2. Go to the Web Service Extensions folder.

  3. Under the Action menu, select Add a new Web service extension....

  4. For Extension name, give it a name such as .cgi or Python cgi or similar.

  5. Under Required files click the Add... button and type in the exact command-line string you used above. Eg: c:\python24\python.exe -u "%s" "%s", then click the Ok button.

  6. Make sure the Set extension status to Allowed checkbox is checked and click the Ok button.

Another change that may be necessary if you are receiving HTTP Error 403 19 1314 while using IIS 6.0 is to adjust the Identity settings for the Application Pool that is being used by your site. The following steps assume you are adjusting the Default Web Site.

  1. Open IIS Manager (Start > Programs > Administrative Tools > IIS Manager).

  2. Go to the Application Pool folder.

  3. Select the Application Pool you wish to adjust. (likely DefaultAppPool ) When you do this on the right you will see the Application pools for each site on the server. This will include a Description (likely Default Application ) and a Path (<Default Web Site>). In this way you can be certain you are adjusting the appropriate Application Pool.

  4. With DefaultAppPool still selected right click and select Properties.

  5. Select the Identity tab and with Predefined clicked use the drop down box to change the Identity to Local System instead of Network Service. Please be aware that this is a workaround since you SHOULD set your group settings to allow Network Service to access the cgi scripts.

Under Windows Server 2003, you will also need to give your IUSR_MACHINENAME account Modify access to the mywiki\data and mywiki\underlay sub-directories, as file system permissions are more restricted by default than previous Windows versions.

You will need to change the Custom Errors setting for 404 before you can create new pages. To do this, follow these steps:

  1. Open IIS Manager, right-click on 'mywiki' (or whatever your wiki instance directory is called), and select Properties.

  2. On the Custom Errors tab, find the 404 entry; click the Set to Default button.

You should now be able 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.

IIS 7.0 (Windows Server 2008)

Configuring wikiconfig.py

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

sitename = u'My Wiki'
logo_string = u'<img src="/mywiki/images/mywiki-logo.gif" alt="MyWiki Logo">My Wiki'

Where "images" is a directory under your "mywiki" instance.

NOTE: The configuration variable "url_prefix" in "wikiconfig.py" should match the alias for "C:\Moin\share\moin\htdocs" or themes will not work ("/wiki" for the instructions above). This way, any reference in "wikiconfig.py" to "/wiki/something" will look in the shared data directory and a reference to "/mywiki/something" will look in the wiki instance directory. These are considered absolute paths because relative paths will not work correctly.

Troubleshooting

IIS URLScan problem

If you see an error like "The system cannot find the file specified." when trying to run Moin on IIS the problem may be URLScan. By default URLScan blocks any URLs that use PATH_INFO. To solve the problem, edit the URLScan.ini file in the %SystemRoot%\system32\inetsrv\urlscan\urlscan.ini directory. I changed the line allowdotinpath from 0 to 1. As follows 

allowdotinpath=1               ; if 1, allow dots that are not file extensions

Also, you might have to add the following setting: 

[options]
AllowHighBitCharacters=1

Next save the URLScan.ini and then restart the IIS service. Your wiki should now work.

For more information, please reference the Microsoft article How to configure the URLScan tool
