Licence

MediaWiki is free software licensed under version 2 of the GNU General Public License. Because MediaWiki is licensed free of charge, there is no warranty, to the extent permitted by applicable law. Read the full text of the GNU GPL version 2 for details.

System Requirements

MediaWiki requires PHP 5.2.3+ (except for 5.3.1) and either MySQL 5.0.2+, PostgreSQL, or SQLite. For more information, please read the system requirements and compatibility.

Note: To get a suitable version of PHP on CentOS 5.6, install the php53 package instead of php.

Download through Git/command line

For downloading MediaWiki from Git or from the command line, see Download from Git.

Notes

• PHP 5 support has been required since MediaWiki 1.7 – if you are using PHP 4, you should upgrade now! It's no longer supported by the PHP group, and has lots of bugs. Many shared hosting providers offer both PHP 4 and PHP 5, running simultaneously. If you cannot upgrade, you should use MediaWiki 1.6.12 (download). Note that this version is no longer supported.
• MySQL 4 support has been required since MediaWiki 1.6 – if you are using an older version of MySQL and cannot upgrade, you should use MediaWiki 1.5.8 (download). Note that this version is no longer supported, but should still support PHP 4 as well.
• MySQL 5 support is required since MediaWiki 1.19 – if you are using an older version of MySQL and cannot upgrade, you should use MediaWiki 1.18.4 (download).

• Project:Test reports is where to report bugs and give feedback about such unstable releases (which often have minor temporary problems, which are quickly fixed... but need to be found first)
