Introduction[edit]

This article gives instructions for people who want to run MediaWiki on a ALT Linux system.

Prerequisites: Apache, MySQL and PHP[edit]

Versions of packages in ALT Linux branch/4.0 are ok for MediaWiki.

Just do a

apt-get update
apt-get install lamp-server
chkconfig httpd2 on
service httpd2 start
chkconfig mysqld on
service mysqld start
a2enmod mod_php5

For branch/p7 you also have to do

apt-get install php5-dom

PHP security configuration[edit]

PHP in ALT Linux has quite secure defaults, so change the following settings in /etc/php/<version>/apache-mod_php/php.ini:

  • safe_mode - turn it off
  • memory_limit - raise to 500M
  • suhosin.executor.func.blacklist, suhosin.executor.eval.blacklist, disable_functions - remove 'system', 'chdir', 'popen' and 'passthru' from those blacklists.
  • remove 'exec', 'shell_exec', 'chdir' from blacklists

Page editing will break on very long pages unless you change the limit in /etc/php/<version>/apache-mod_php/php.d/suhosin.ini:

  • suhosin.post.max_value_length - increase it to 650000

Do

service httpd2 restart

Installation[edit]

For experienced users, here is the quick version of the installation instructions. Most users will want to go through all the passages.

  1. Check that your system meets the minimum requirements shown nearby; Installation requirements has more details.
  2. Download MediaWiki (direct link to download the stable release version) and extract the archive to a web-accessible folder on your server.
  3. Point your browser to the directory where MediaWiki was extracted and follow the link to the setup screen. It should be in the form http://domain/directory/mw-config/index.php. Replace directory with the path to your extracted MediaWiki folder. If installing on a local machine, replace domain with localhost. If you install locally and later want to access your wiki from domain, then you will need to change LocalSettings.php from localhost to domain. If installed on a remote server, replace domain with your server's domain name (eg: www.myserver.com).
  4. Follow the on-screen instructions to complete the process.

These instructions are deliberately brief. There is a lot that could go wrong, so if in doubt, you are advised to read the full instructions!
