MariaDB/MediaWiki

You must install either MySQL or MariaDB on your Linux distribution. MariaDB is strongly preferred, but otherwise they are both compatible as they are forks.

Then, follow these instructions to set up the database securely.

Now, start the MySQL/MariaDB server for the first time.

sudo systemctl start mysql

Once the server works, enable it to start at every boot.

sudo systemctl enable mysql

Finally, create a database and user for MediaWiki to use. Remember this database name, username and password, since you will need it once you configure MediaWiki. Change the password placeholder with your real password.

sudo mysql

CREATE DATABASE wikidb;
GRANT ALL PRIVILEGES ON wikidb.* TO 'wikiuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
