Configuring and hardening security

see [https://www.mediawiki.org/wiki/Manual:Security]

Configure MySQL

sudo mysqladmin -u root password "enter the new password here"

sudo mysql_secure_installation

and follow defaults

Create user for mediawiki

sudo mysql

> CREATE DATABASE <databasename>;

> CREATE USER 'mediawiki'@'localhost' IDENTIFIED BY '<password>';

> USER <databasename>;

> GRANT SELECT, INSERT, UPDATE, DELETE, ALTER ON <databasename>.* TO 'mediawiki'@'localhost';

less secure alternativeGRANT ALL PRIVILEGES ON *.* TO 'mediawiki'@'localhost' IDENTIFIED BY 'password';

Configure PHP

Edit /etc/php/7.3/apache2/php.ini

set

upload_max_filesize = 20M

memory_limit = 128M

register_globals = Off

allow_url_fopen = Off

session.use_trans_sid = 0

Configure MediaWiki

cd /var/www/html

sudo ln -s /var/lib/mediawiki mediawiki

goto http://<hostname>/mediawiki to configure using mysql username and database created earlier

copy LocalSettings.php to /var/lib/mediawiki on host

and harden suecurity

change ownership of mediawiki files

chown -R <username>:<username> /path/to/mediawiki/

where <username> could be your own username but not root or apache user www-data

but mediawiki needs access to images (and cache if using)

chown -R www-data:www-data /path/to/mediawiki/images

chown -R www-data:www-data /path/to/mediawiki/cache

and ensure no write access to other users

chmod -R go-w /path/to/mediawiki
