Overview
A full new installation of the latest LTS (Long Term Support) Media Wiki instance is in most cases the best option, for both new deployments and restoration of older deployments from backup. This procedure has been written to support both new deployments and restoration of old deployments from backup and possibly upgrade into the new instance.
Pick the Latest LTS Release
Always install the latest LTS (Long Term Support) release.
Pick the latest LTS minor version from this pages:
Pick the latest patch version from this page, by navigating down the minor version folder and selecting the latest released patch:
The article was last updated for Media Wiki 1.39.6.
Install httpd
Install or upgrade to the newest stable httpd version for your platform. The Media Wiki compatibility page does not recommend any specific httpd version.
Installation instructions:
Install letsencrypt Certificates
The specific Media Wiki SSL and certificate configuration from /etc/httpd/conf.d/ssl.conf (the Listen directive and the only virtual host) and /etc/letsencrypt or /etc/pki/tls must be transferred manually from the backup file, after the web server and generic HTTPS support is installed.
No change in /etc/httpd/conf/httpd.conf should be required. If the state of another wiki is restored, the restoration script will remind of the need to apply SSL configuration and the required steps.
PHP
PHP Installation
Select the newest compatible stable version from:
It is probably OK to install the latest stable PHP version even if it is not explicitly specified on the compatibility page. Media Wiki 1.39 works well with PHP 8.3 even if PHP 8.3 is not mentioned on the compatibility page.
Installation and httpd configuration instructions:
PHP Configuration
Some PHP installations come with error reporting set to dump all errors, including some not appropriate for production, like deprecation messages.
Install MariaDB
Select the newest compatible stable version from:
It is probably OK to install the latest stable MariaDB version even if it is not explicitly specified on the compatibility page.
Installation and post-install configuration instructions:
Install the Media Wiki Release
Go to https://releases.wikimedia.org/mediawiki/, download the latest patch corresponding to the selected LTS release and expand it in the httpd document root.
Perform a New Instance Initialization
Regardless on whether we are installing a new Media Wiki instance to use it as such, or we intend do restore an old instance, a full new instance initialization is required in both cases.
Create the MariaDB Database
This procedure will create the Media Wiki dedicated database user and database. The difference between a new installation that will used as such and a new installation that will be used to restore an old instance is that in the former case the database and the user created now will be used in production. In the latter case, they will be eventually be discarded and deleted, to be replaced with the restored database and user.
⚠️ Do not use "=" as a password character.
For a new instance to be used in production, use valid, production values:
export MEDIAWIKI_USER=novaordis_wiki
export MEDIAWIKI_PASSWORD=... # Do not use "=" as a password character
export MEDIAWIKI_DATABASE=novaordis_wiki
For a restoration:
export MEDIAWIKI_USER=tmp_mediawiki_user
export MEDIAWIKI_PASSWORD=tmp_mediawiki_passwd
export MEDIAWIKI_DATABASE=tmp_mediawiki_db
Connect to MariaDB using the database root password configured when the database cluster was installed.
Configure httpd to Serve the Media Wiki Instance
Run the Initialization Procedure and Create LocalSettings.php
Post Restoration
Database Cleanup
Drop the temporary database and user:
DROP DATABASE tmp_mediawiki_db;
DROP USER 'novaordis_wiki'@'localhost';
COMMIT;
