Server Installation

How to setup MoinMoin for various web servers / gateway interfaces.

Please note that you require server admin experience for a server installation. It is not in the scope of this documentation to teach you (web) server configuration/administration, but just to show you how MoinMoin is installed. If you are unsure about your experience level, please try the Quick Installation first.

MoinMoin and WSGI

MoinMoin is a WSGI application, therefore the best environment to run a MoinMoin instance in is a WSGI-aware one.

Here are some of them:

Also we will cover some legacy deployment methods for serving MoinMoin from non-WSGI-aware setups. The needed adapters are included in the MoinMoin distribution.

Apache with mod_wsgi

The details of how to install mod_wsgi or Apache is out of scope of this document. Please follow the install instructions for each respective software package. The Apache documentation is here, and the mod_wsgi instructions has set-up details. Some users have documented their install process in detail on the user-supported how-to page on the MoinMoin wiki.

If everything has been configured to your liking, you can test your setup with the application contained in test.wsgi (please read the hints included in the file).

Some further hints for usage of mod_wsgi:

MoinMoin specific installation

MoinMoin installation

You may, but do not need to, install MoinMoin to system specific locations via the use of setup.py.

(!) You can place the MoinMoin package (a directory called MoinMoin/ containing most of the code) anywhere you like, no specific location in the filesystem is required.

If you choose to use setup.py, you can install MoinMoin using:

python setup.py install --force --record=install.log --prefix='/usr/local' --install-data=/srv
# or alternatively, to the default system location:
python setup.py install --force --record=install.log
# --force is important, without it setup.py might not overwrite outdated files at the destination

With --install-data=/path you could change the prefix of the wiki instance directory (share/moin) to /path.

/!\ Please note that using setup.py as shown above will overwrite all files at the destination. So if you modified files there, your modifications will be lost. However it won't remove outdated files there so if you had used setup.py before for the same destination, maybe clean up at the destination before installing a new moin version.

(!) If you need to modify files, do not do so in their original location, but copy them to some safe place first and then edit them there.

The file install.log will contain a complete log of installed files.

You may want to keep it in case you have trouble locating some of the file(s) mentioned below.

Python path setup

Code: From here on we will use /moin/code to refer to the parent directory of the MoinMoin/ package directory.

Config: You can place the wiki config files (they are just Python code) anywhere you like, no specific location is required. We will use /moin/config to refer to the directory that contains your wiki config files.

To make MoinMoin and Python find the needed files, you need to make those locations known:

For this to work, you can simply edit moin.wsgi (or in case you deploy with CGI/FCGI/etc.: the corresponding script for these deployment methods from the wiki/server/ directory). There is already example code in those files, just remove the comment (# hash character) and change them accordingly:

sys.path.insert(0, '/moin/code')
sys.path.insert(0, '/moin/config')

You can place moin.wsgi anywhere you like. Just make your web server find and use it.

MoinMoin wiki configuration

Although the code is now ready to run, your wiki is not configured yet.

You now have to create your wiki configuration within the /moin/config/ directory.

Single wiki

Just copy the file wiki/config/wikiconfig.py from the distribution archive to /moin/config/.

The file is thoroughly commented to ease you through the configuration. Make sure that if you configure paths in the file, that those paths are absolute paths. This way you ensure that the needed files are definitely found and save yourself some troubles. The essential configuration directives are:

/!\ We don't require any specific file system locations, but please be careful: data_dir contains sensitive informations that must not be read by anything or anyone except the running moin wiki code. For example, you must not make data_dir accessible directly via the web server, thus you must not copy it to a directory below document root of your web server. Any other permanent storage location on a fast local filesystem will be fine.

You need to copy the complete contents of the wiki/data/ directory we provide in the distribution archive to the location you specified as data_dir. The same goes for wiki/underlay/ and the location you specified as data_underlay_dir.

Multiple wikis

Just copy the files wiki/config/wikifarm/* from the dist archive to /moin/config/.

Now follow the directions as for a single wiki (see above) for each of your farm wikis.

Special wiki farm hints:

Static file serving

MoinMoin also comes with some static files like images, CSS, Javascript, Java applet files, etc. (see the MoinMoin/web/static/htdocs/ directory in the distribution archive). They are needed for things like styling, icons and additional client-side functionality.

MoinMoin serves those files by a built-in static file server at the path '/moin_staticXYZ' (XYZ like in MoinMoin version X.Y.Z, e.g. /moin_static190 for moin 1.9.0).

Please note that this path is relative to the script root, so:

Running MoinMoin with Apache / mod_wsgi

Now you should be able to simply run the moin.wsgi script the same way you ran test.wsgi above.

Running MoinMoin with other WSGI servers

Have a look at moin.wsgi and the documentation of your web server's WSGI support. As WSGI is a standard, it should be quite similar and easy to adapt.

Running MoinMoin with CGI, FastCGI, SCGI or AJP

If you are not running a WSGI capable server and want to deploy MoinMoin with one of the other methods (like CGI, FastCGI, SCGI or AJP), just use the appropriate script for the desired method from wiki/server/ (instead of moin.wsgi):

Now edit that script (similarly as shown above for moin.wsgi) to make Python find the moin code and wiki configuration files.

For setting up your particular web server to speak any of these protocols to the moin application, please refer to the web server's documentation.

/!\ When using the scripts for FastCGI, SCGI or AJP (not CGI), be aware that they can also act as externally spawned processes to the web server. Via the means of commandline parameters they can be bound to an interface or UNIX socket and also do threading or forking for performance.

Try running moin.cgi --help for an example. When run without any options by the web server, control of sockets and the like is left to the web server.

Note: The non-WSGI deployment scripts use flup to convert FastCGI/SCGI/AJP/CGI to WSGI (we bundle flup with moin). Please see the flup documentation for more details.

Running MoinMoin with anything else

In the unlikely case none of the above deployment methods work for you, you can try to:

Alternatively, you can also run moin with any of the supported methods (on some other IP or some other port) and use your (unsupported) main web server as a proxy.

Testing your setup

You can test if everything works by following these steps:
