/!\ Voodoo is not for newbies!

This page gives some nice but advanced tricks for a moin Apache setup. The directives on this page assume that you have knowledge about Apache configuration, newbies should stick to the basic setup.


= Apache Root Wiki =

/!\ This requires the Apache module "mod_rewrite" (which should be standard)

An Apache root wiki is easy, but it has limitations. Since moin needs to access certain static files (images, css, etc.), it intercepts a part of the possible WikiName namespace.

 1. Install moin as normal.
 1. Add the following lines to your VirtualHost config:
  {{{
  RewriteEngine On
  RewriteLogLevel 0
  
  # Point to moin shared static files - DEPENDS ON MOIN VERSION!
  RewriteRule ^/moin_static160/(.*)$ /prefix/share/moin/htdocs/$1 [last]
  
  # Map everything else to moin cgi script
  RewriteRule ^(.*)$ /path/to/moin.cgi$1 [type=application/x-httpd-cgi]
  
  # Setting for FastCGI
  ##RewriteRule ^(.*)$ /path/to/moin.fcg$1 [type=application/x-httpd-fcgi]
}}}

The RewriteRule for Fast''''''CGI here does not work for me: {{{
[Wed Jan 05 01:43:41 2005] [error] [client 10.0.0.1] File does not exist: /home/apache/moin/wiki/share/moin/pw/moin.fcg/RecentChanges, referer: http://moin.dahoam/StartSeite
duplo:/home/danielt# ls /home/apache/moin/wiki/share/moin/pw/moin.fcg
-rwxr-xr-x  1 root  www  1088 Jan  4 23:35 /home/apache/moin/wiki/share/moin/pw/moin.fcg*
}}}

As a workaround I use this: {{{
  RewriteRule ^/?(.*) /_Wikiscript_/moin.fcg/$1
  RewriteRule ^/_Wikiscript_/(.*) /home/apache/moin/wiki/share/moin/pw/$1 [last]
}}}


= Root wiki on Mac OSX =
/!\ This configuration intercepts all userfolder URLs like ''`http://127.0.0.1/~yourname/`'' and offers a blank wiki page instead, so these instructions are offered as an exercise only. There may be a way around this problem but I don't know what it is.

Using the previous information on the moin OS X installation, you end up with a virtual host block like this:
{{{
<VirtualHost *>
   ServerName Gnarlodious
   Alias /moin_static160/ /usr/local/share/moin/htdocs/
   ScriptAlias /mywiki /usr/local/share/moin/mywiki/moin.cgi
   RewriteEngine On
   RewriteRule ^/moin_static160/(.*)$ /usr/local/share/moin/htdocs/$1 [last]
   RewriteRule ^(.*)$ /usr/local/share/moin/mywiki/moin.cgi$1 [type=application/x-httpd-cgi]
</VirtualHost> 
}}}
Remove the following `<IfModule mod_alias.c>` directives added on [[HelpOnInstalling/ApacheOnMacOsx|this page]], as they are now redundant:
{{{
    Alias /moin_static160/ "/moinwiki/share/moin/htdocs/"
    ScriptAlias /mywiki "/moinwiki/share/moin/mywiki/moin.cgi"
}}}
Now restart Apache. You should be able to open a URL like http://127.0.0.1/HelpOnInstalling/ApacheOnMacOsx


= Root wiki with mod python recipe =

Using the above example, I got this working like this:

 1. Install moin as usual and create instance
 1. Use this config in httpd.conf
  {{{
NameVirtualHost 192.115.134.51:80
<VirtualHost 192.115.134.51:80>
    ServerName wiki.nirs.dyndns.org
    ServerAlias wiki
    
    # Rewrite urls
    RewriteEngine On
    RewriteLogLevel 0
    # map static files to htdocs
    RewriteRule ^/moin_static160/(.*)$ /usr/share/moin/htdocs/$1 [last]
    # map everything else to server script
    RewriteRule ^(.*)$ /usr/share/moin/mywiki/moinmodpy.py$1

    <Directory "/usr/share/moin/mywiki">
        # These are copied from the default cgi-bin directory
        AllowOverride None
        Options None
        Order allow,deny
        Allow from all

        # Modpy stuff
        AddHandler python-program .py
        # Add the path to the wiki directory, where moinmodpy.py and 
        # wikiconfig.py are located.
        PythonPath "['/usr/share/moin/mywiki'] + sys.path"
        PythonHandler moinmodpy
        PythonDebug On 
    </Directory>
</VirtualHost>
}}}

(!) It seems to be impossible to get a root modpy wiki without using the moinmodpy wrapper script.
