MediaWiki is available as a part of Fedora Extras (4 or later). In order to install it, you should run

# yum install mediawiki

as root. After installation, open the file /usr/share/doc/mediawiki-x.y.z/INSTALL.fedora and follow the instructions there.

Note that in recent installations the INSTALL file is at /usr/share/mediawiki/INSTALL

If you need support for mathematical formulas, you also need to install mediawiki-math:

# yum install mediawiki-math

If you have a more recent Fedora, there is no package mediawiki-math. Because mediawiki requires "texvc" for LaTeX you'll also need to install LabPlot

# yum install LabPlot

On Fedora Core 4, installing version 1.5.8-1, additional steps are needed to enable inline LaTeX translation. Some of these steps are described in the following file:

/usr/share/doc/mediawiki-math-1.5.8/README

If LaTeX formulas are displayed without translation, you might need to uncomment the following line manually in LocalSettings.php, and possibly also restart your httpd server:

$wgUseTeX = true;

Here is a method to restart the httpd server under Fedora:

/etc/init.d/httpd restart       - from root prompt (not recommended) 
sudo /etc/init.d/httpd restart  - from user prompt with sudo configured

After enabling $wgUseTeX, you might see an error message such as this:

In MediaWiki file Math.php one finds this source code line:

global $wgMathDirectory, $wgTmpDirectory, $wgInputEncoding;

In my default LocalSettings.php I found these lines:

$IP = "/var/www/mediawiki";
$wgUploadDirectory  = "$IP/images";
# ...
$wgMathDirectory    = "{$wgUploadDirectory}/math";
$wgTmpDirectory     = "{$wgUploadDirectory}/tmp"; 
$wgTexvc            = '/usr/bin/texvc';
$wgUseTeX           = true;

Which suggested this fix:

cd /var/www/mediawiki/images
sudo mkdir math 
sudo mkdir tmp 
sudo chown apache math tmp
sudo chmod 775 math tmp 

And then there was math.

For Fedora-specific bug reports, use http://bugzilla.redhat.com/ with the product field set to "Fedora Extras" and the component field to "mediawiki".

If you have no error with php but no png generated, it's seems to be a problem with a configuration file of Tex. I solved my problem executing

fmtutil-sys --all
