Apache configuration/fr

Apache est le serveur recommandé pour faire fonctionner MediaWiki. D'autres serveurs comme IIS peuvent fonctionner.

PHP en tant que module Apache
MediaWiki est écrit pour utiliser en tant que module Apache. Votre PHP est probablement configuré en tant que module si vous démarrez avec une entrée du type : example.com/index.php/Main_Page Vous pouvez vérifier la configuration et la version de PHP dont vous bénéficiez en visualisant la page Spécial:Version de votre wiki ou bien avec phpinfo.

Serveur Linux sur base RedHat/Fedora
Installez PHP : Rechargez httpd:
 * 1) yum install php php-xml
 * 1) service httpd reload

Serveur Linux sur base Debian
Installez le module apache2 php5 : Activez le module apache2 php5 : Redémarrez Apache: (Debian also has a mediawiki package.)
 * 1) apt-get install apache2 libapache2-mod-php5 php5-cli php-apc php5-mcrypt
 * 1) a2enmod php5
 * 1) apache2ctl restart

PHP as CGI
If PHP is running as a CGI, you will have "ugly" URLs by default, but you can still implement.

CGIWrap
If you have your own server running Apache and are running, you can install CGIWrap. This tool enables you to run the Apache server as a different user for CGIs.

That way, you can create a new user for your MediaWiki pages. Installing CGIWrap is beyond the scope of this document, especially since you must compile it accordingly to your own server. However, as a quick guideline, you can follow these rules:

useradd -M -s /sbin/nologin wikiuser chown apache:apache cgiwrap chmod 500 cgiwrap ln -s /home/myuser/public_html/wiki /home/myuser/cgi-bin/wikilink AddHandler php-wrapper .php Action php-wrapper /cgi-bin/cgiwrap/wikiuser/wikilink chown -R wikiuser:wikiuser *.php chmod -R 500 *.php The files will be accessible as usual. You do not need to specify in your path any cgi-bin, as this is transparently taken care for you.
 * Create a Wikimedia user
 * Have a cgi-bin folder, containing CGIWrap (example in /home/myuser/cgi-bin). Once everything is configured, keep only cgiwrap, move the debug versions to another folder if you ever need it. Your cgiwrap file should be accessible only to Apache (chown and chmod accordingly).
 * Inside the cgi-bin folder, create a symbolic link to the Wikimedia root.
 * In your wiki's .htaccess file, add the following definitions:
 * Finally, chown and chmod all the .php files of your Wikimedia folder to be accessible solely by wikiuser.

I strongly suggest you start out with /cgi-bin/cgiwrapd/... as your php-wrapper, as it will precisely show what is currently working. I also strongly suggest you do not delete your CGIWrap source folder until everything works perfectly as this is a real trial and error process, taking a long time. However, it's all worth your time as your MediaWiki will be run in its own separate process, in its own uid, without being able to interfere any other uid. Inverse is also true, except for root, that can read anything anywhere.

mod_alias and mod_rewrite
The recommended method of involves mod_alias. Other methods use mod_rewrite instead.

mod_security
has been known to cause problems with MediaWiki. If you get errors seemingly at random, check your error log to see whether it is causing problems.

Thread stack size
The stack size for for each Apache thread is configurable and the default varies on different operating systems. To run MediaWiki on Windows environments it may be necessary to increase the stack size (if there are problems), as the 1MB default is small and can cause stack overflows during PHP script execution. The following httpd.conf setting will set the stack size to about 8MB (about a typical Linux default):

Spiders and bots
You can use a file to tell well-behaved spiders not to download dynamically generated pages (edit pages, for instance). This can reduce the load on your webserver, preserve your bandwidth, and prevent duplicate content issues with search engines. However, malicious bots could tie up your webserver and waste your bandwidth by downloading a large volume of pages extremely quickly. Request throttling can help protect against this.
