Apache configuration/oc

Apache is probably the webserver used most with MediaWiki.

PHP en tant que modul Apache
MediaWiki is written to use as an Apache module. Your PHP is probably configured as a module if you start with URLs like this: example.com/index.php/Main_Page You can check which configuration and version of PHP you have by viewing your wiki's Special:Version page, or with phpinfo.

Servidor Linux sus base RedHat/Fedora
Installatz PHP : Recargatz httpd:
 * 1) yum install php php-xml
 * 1) service httpd reload

Servidor Linux sus basa Debian
Installatz lo modul apache2 php5 : Activatz lo modul apache2 php5 : Reaviatz Apache:
 * 1) apt-get install apache2 libapache2-mod-php5 php5-cli php-apc php5-mcrypt
 * 1) a2enmod php5
 * 1) service apache2 restart

PHP en tant que 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
 * 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).

ln -s /home/myuser/public_html/wiki /home/myuser/cgi-bin/wikilink AddHandler php-wrapper .php Action php-wrapper /cgi-bin/cgiwrap/wikiuser/wikilink
 * 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.

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.

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 / 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 really should 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.
