MediaWiki

MediaWiki requires the iconv extension, so you need to uncomment extension=iconv in /etc/php7/php.ini.

Optional dependencies:

• For thumbnail rendering, install either ImageMagick or php7-gd. If you choose the latter, you also need to uncomment extension=gd.
• For more efficient Unicode normalization, install php7-intl and uncomment extension=intl.

Enable the API for your DBMS:

• If you use MariaDB, uncomment extension=mysqli.
• If you use PostgreSQL, install and uncomment .
• If you use SQLite, install and uncomment .

Second, tweak the session handling or you might get a fatal error () by finding the session.save_path path. A good choice can be /var/lib/php/sessions or .

You will need to create the directory if it does not exist and then restrict its permissions:

# mkdir -p /var/lib/php/sessions/
# chown http:http /var/lib/php/sessions
# chmod go-rwx /var/lib/php/sessions

If you use PHP's open_basedir and want to allow file uploads, you need to include (mediawiki symlinks to ).

Follow Apache HTTP Server#PHP.

Copy to and edit it as needed.

Add the following line to :

Include conf/extra/mediawiki.conf

Restart the daemon.

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

/etc/nginx/mediawiki.conf

location / {
   index index.php;
   try_files $uri $uri/ @mediawiki;
}
location @mediawiki {
   rewrite ^/(.*)$ /index.php;
}
location ~ \.php$ {
   include /etc/nginx/fastcgi_params;
   fastcgi_pass unix:/var/run/php-fpm7/php-fpm.sock;
   fastcgi_index index.php;
   fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
   try_files $uri @mediawiki;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
   try_files $uri /index.php;
   expires max;
   log_not_found off;
}
# Restrictions based on the .htaccess files
location ~ ^/(cache|includes|maintenance|languages|serialized|tests|images/deleted)/ {
   deny all;
}
location ~ ^/(bin|docs|extensions|includes|maintenance|mw-config|resources|serialized|tests)/ {
   internal;
}
location ^~ /images/ {
   try_files $uri /index.php;
}
location ~ /\. {
   access_log off;
   log_not_found off; 
   deny all;
}
location /rest.php {
   try_files $uri $uri/ /rest.php?$args;
}

Ensure that is installed and is started.

Include a server directive, similar to this

Finally, restart and daemons.

You should have Lighttpd installed and configured. "mod_alias" and "mod_rewrite" in server.modules array of lighttpd is required. Append to the lighttpd configuration file the following lines

Restart the daemon.

Set up a database server as explained in the article of your DBMS: MariaDB, PostgreSQL, SQLite or MySQL.

If you have set a non-empty root password for the database server, MediaWiki can automatically create the database during the next step. (See MariaDB#Reset the root password for how to set this password retrospectively for MariaDB.) Otherwise the database needs to be created manually - see upstream instructions.

Open the wiki URL (usually http://your_server/mediawiki/index.php) in a browser and do the initial configuration. Follow upstream instructions.

The generated file is offered for download, save it to and create symbolic link to it from :

# ln -s /etc/webapps/mediawiki/LocalSettings.php /usr/share/webapps/mediawiki/LocalSettings.php

This file defines the specific settings of your wiki. Whenever you upgrade the mediawiki package, it will not be replaced.

Usually installing texvc and enabling it in the configuration is enough:

$wgUseTeX = true;

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

Check that PHP, Apache HTTP Server and MariaDB all use UTF-8. Otherwise you may face strange bugs because of encoding mismatch.

The VisualEditor MediaWiki extension provides a rich-text editor for MediaWiki. Follow mw:Extension:VisualEditor to install it.

You will also need the Parsoid Node.js backend, which is available in .

Adjust the path to MediaWiki in :

parsoidConfig.setInterwiki( 'localhost', 'http://localhost/mediawiki/api.php' );

After that enable and start .

Alternatively, one may also use the package, and configure the service via the yaml file, where the following lines should be present:

The matching part in the mediawiki settings:

/etc/webapps/mediawiki/LocalSettings.php

$wgVirtualRestConfig['modules']['parsoid'] = array(
  // URL to the Parsoid instance - use port 8142 if you use the Debian package - the parameter 'URL' was first used but is now deprecated (string)
  'url' => 'http://localhost:8000/',
  // Parsoid "domain" (string, optional) - MediaWiki >= 1.26
  'domain' => 'localhost',
  // Parsoid "prefix" (string, optional) - deprecated since MediaWiki 1.26, use 'domain'
  'prefix' => 'localhost',
  // Forward cookies in the case of private wikis (string or false, optional)
  'forwardCookies' => false,
  // request timeout in seconds (integer or null, optional)
  'timeout' => null,
  // Parsoid HTTP proxy (string or null, optional)
  'HTTPProxy' => null,
  // whether to parse URL as if they were meant for RESTBase (boolean or null, optional)
  'restbaseCompat' => null,
);

After configuration, the service may be started (restarted) and (if not done yet) enabled.
