Start with a WebServer

• Building Web Servers

Now Do A Backup!

Download MediaWiki

• Check the download page for latest version. (ATM, the current version turns out to be 1.40.1)
  • Adjust the following commands appropriately (i.e.: replace 1.40.1 with the current version number) if needed.
• wget https://releases.wikimedia.org/mediawiki/1.40/mediawiki-1.40.1.tar.gz

Unpack MediaWiki

• Extract it
• tar -xvzf mediawiki-1.40.1.tar.gz

There are a couple of different ways to set up the root of your wiki.

You can either set it up to be reached

as part of your regular web site

• sudo mkdir /var/www/html/wiki
• sudo cp -r mediawiki-1.40.1/* /var/www/html/wiki
• sudo chmod -R ugo+rwX /var/www/html/wiki/images

Your wiki will be reached at http://www.ServerAddress.tld/wiki/

or at an independent URL

• sudo mkdir /var/www/wiki
• sudo cp -r mediawiki-1.40.1/* /var/www/wiki
• sudo chmod -R ugo+rwX /var/www/wiki/images

Your wiki will be reached at http://wiki.ServerAddress.tld/

(Once you set up Name-based Virtual Host Support)

Set Up MediaWiki

Create the database

• sudo mysql -u root -p

CREATE DATABASE MY_WIKI;
GRANT ALL PRIVILEGES ON MY_WIKI.* TO 'USERNAME'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace MY_WIKI with a database name of your choice. If you are installing multiple wikis on a single server, they each need a uniquely named database.

Replace USERNAME with the username you set up while installing the LAMP Stack

Adjust PHP Settings

• sudo vi /etc/php/8.2/apache2/php.ini

(this may be in a slightly different location depending on version of php installed...)

increase upload_max_filesize to 200M

increase post_max_size to 200M

Your wiki is installed

Now Do A Backup!

Browse to http://www.ServerAddress.tld/wiki/ or http://wiki.ServerAddress.tld/ (depending on which way you set it up above...)
