#* If your Apache server has the [http://www.hardened-php.net/ Hardened PHP patch], you may need to edit several variables in your /etc/php.ini file if you wish to have Wiki pages with large amounts of content. In particular, consider the settings for varfilter.max_value_length, hphp.post.max_value_length, and hphp.request.max_value_length. The default settings may limit your pages to less than 10k or 64k in size.
#* Many people report blank pages in recent versions after submitting articles to their new wiki. A likely cause is the memory limit in default php installations (usually 8 MB). Please check your PHP and/or Apache error logs. To modify this setting edit <code>/etc/php.ini</code> and increase the "memory_limit" setting. For example to raise it to 20 MB replace the existing text with "<code>memory_limit = 20M</code>". Make sure to restart your Apache server after you have changed this value.
# A '''MySQL database server (4.0 or later)''', which will be used to store all the text and data. This is available from the [http://dev.mysql.com/downloads/ official download page].
#* As of version 1.8, [http://www.postgres.org Postgres] is also supported. It should be noted that support for Postgres is very new and not as well tested as the MySQL equivalent.
# '''MediaWiki itself''', which is available from the [http://www.mediawiki.org/wiki/Download official download page]. Development versions are available from the [http://sourceforge.net/projects/wikipedia/ Sourceforge.net project page].
