Note: If you are using xampp, there are different steps you need to take after installing. More info here

Installation

Follow the LAMP guide. Then Install php-gd and uncomment ;extension=gd.so in php.ini, same for php-intl (needs icu) and php-xcache (here add extension=xcache.so) and finally install mediawiki, all available from the official repositories.

Instead of mysql you can install sqlite3 or postgresql.

Configuration

First, adjust the open_basedir in /etc/php/php.ini to include the webapps directory (allows update.php to be run from the command line):

open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/

Now do the steps corresponding to your web server.

Apache

Create /etc/webapps/mediawiki/httpd-mediawiki.conf from the provided example apache.example.conf in the same directory. Edit it to remove the open_basedir line, which is already in php.ini.

  • Add the following lines to /etc/httpd/conf/httpd.conf
LoadModule php5_module modules/libphp5.so
Include conf/extra/php5_module.conf
Include /etc/webapps/mediawiki/httpd-mediawiki.conf
  • Adjust permissions in /usr/share/webapps/mediawiki/.htaccess, e.g. to

allow from all

Restart the httpd.service daemon.

Open the wiki in a browser and do the initial setup to create LocalSettings.php. Then save it to /usr/share/webapps/mediawiki/LocalSettings.php.

Nginx

To get MediaWiki working with Nginx, create the following file:

/etc/nginx/mediawiki.conf

location / {
   index index.php;
   try_files $uri @mediawiki;
}
location @mediawiki {
   rewrite ^/([^?]*)(?:\?(.*))? /index.php?title=$1$2 last;
}
location ~ \.php?$ {
   include fastcgi.conf;
   fastcgi_pass php;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
   try_files $uri /index.php;
   expires max;
   log_not_found off;
}
location ^~ /maintenance/ {
   return 403;
}
location ^~ /cache/ {
   deny all;
}

Ensure that php-fpm is installed, and in your /etc/nginx/nginx.conf file, ensure that you have an upstream directive named php, similar to this one:

/etc/nginx/nginx.conf
upstream php {
   server unix:/var/run/php-fpm/php-fpm.sock;
}

Include a server directive, similar to this

/etc/nginx/nginx.conf
server {
  listen 80;
  server_name mediawiki;
  root /usr/share/webapps/mediawiki;
  index index.php;
  include mediawiki.conf;
}

Tips and tricks

Mathematics (texvc)

Usually installing texvc package and enabling it in config are enough:

 $wgUseTeX = true;

If you get problems, try to increase limits for shell commands:

 $wgMaxShellMemory = 8000000;
 $wgMaxShellFileSize = 1000000;
 $wgMaxShellTime = 300;

Unicode

Check that php, apache and mysql uses UTF-8. Otherwise you may face strange bugs because of encoding mismatch.
