Here is the NixOS configuration that you need to get a MediaWiki instance:

edit mediawiki but NO vhosts yet

services.postgresql.enable = true;
services.httpd.enable = true;
services.httpd.adminAddr = "admin@example.org";
services.httpd.extraSubservices =
  [ { serviceType = "mediawiki";
      siteName = "My Wiki";
      logo = "http://www.example.org/wiki-logo.png"; # should be 135x135px
      extraConfig =
        ''
          # See http://www.mediawiki.org/wiki/Manual:Configuration_settings
          $wgEmailConfirmToEdit = true;
        '';
    }
  ];

Then run nixos-rebuild switch. The MediaWiki database will be created automatically.

You should also set up a user account for the administrator. This can be done from the command line:

$ mediawiki-main-createAndPromote --bureaucrat God foobar

Note that various other MediaWiki commands are also accessible from the command line. For instance:

$ mediawiki-main-changePassword --user alice --password foobar

edit mediawiki and vhosts

this example features two vhost entries:

• a normal webpage with an index.html
• a mediawiki presence (which is found at wiki.example.com or wiki.example.com/mywiki

  services.postgresql.enable = true;

  services.httpd = {
    enable = true;
    logPerVirtualHost = true;
    adminAddr="example@example.com";
    hostName = "example.com";

    virtualHosts =
    [ 
      {
        hostName = "www.example.com";
        serverAliases = ["www.example.com"];
        documentRoot = "/www";
      }
     { 
        # Note: do not forget to add a DNS entry for wiki.example.com in the DNS settings
        hostName = "wiki.example.com";
        extraConfig = ''
            RedirectMatch ^/$ /mywiki
          '';
        extraSubservices =
        [
          {
            serviceType = "mediawiki";
            siteName = "My Wiki";
            articleUrlPrefix = "/mywiki";
            #logo = "http://www.example.org/wiki-logo.png"; # should be 135x135px
            extraConfig =
              ''
                # See http://www.mediawiki.org/wiki/Manual:Configuration_settings
                $wgEmailConfirmToEdit = true;
              '';
          }
        ];
      }
    ];
  };

edit 2 or more mediawiki instances using vhosts

notice the added new attributes:

• id="wiki1"
• dbName="mediawiki_wiki1"

the second attribute set (remember? { ... } <- this way looks an attribute set) is just a copy of the first with some modifications as the id and dbname must be different, as well as some other values.

  services.postgresql.enable = true;

  services.httpd = {
    enable = true;
    logPerVirtualHost = true;
    adminAddr="example@example.com";
    hostName = "example.com";

    virtualHosts =

      {
        hostName = "www.example.com";
        serverAliases = ["www.example.com"];
        documentRoot = "/www";
      }
     { 
        # Note: do not forget to add a DNS entry for wiki.example.com in the DNS settings
        hostName = "wiki.example.com";
        extraConfig = ''
            RedirectMatch ^/$ /mywiki
          '';
        extraSubservices =
        [
          {
            serviceType = "mediawiki";
            id="wiki1";
            dbName="mediawiki_wiki1";

            siteName = "My Wiki";

        ];
      }
      {

        hostName = "wiki2.example.com";
        extraConfig = ''
