Why Meza?

edit

To make it possible for everyone to have a modern, fully-featured MediaWiki installation. Standard MediaWiki is easy to install, but increasingly its newer and better features are contained within extensions with more complicated install procedures. Additionally, they may be particularly difficult to install on Enterprise Linux derivatives (e.g. Red Hat, CentOS, etc.). This project aims to make features like VisualEditor, CirrusSearch, etc., easy to install, backup, reconfigure, and maintain in a robust and well-tested way.

Who is using Meza?

Requirements

edit
  1. System Requirements:
    1. 8GB RAM minimum suggested. For trying out Meza with 2GB RAM or even less, see Meza/Setup on a low-memory system
    2. 25GB minimum available free space in /opt (Linux). Meza will initially use <2GB but logs and media can easily require much more over time.
  2. Operating system:
    1. Rocky Linux 8.9 (RHEL 8 equivalent)
    2. Mac, Windows, or Linux using the Vagrant or Virtual Box install instructions
  3. Minimal install: Attempting to install it on a Linux server with many other packages already installed may not work properly due to conflicts
  4. Mail: meza does not configure any mail services. The best option is to use the $wgSMTP mediawiki variable to attach to an external SMTP service.

See Meza/Known Enterprise Challenges for challenges, conflicts, and common errors.

Install

edit

There are step-by-step explanations of how to set up Meza in the following environments:

  1. Install with Vagrant: This is the easiest way to try Meza on your personal computer
  2. Install on Virtual Box: This requires a little more work, but is good if you don't like Vagrant
  3. Install on existing server: This assumes you already have a server you can SSH into
  4. Install on Wikimedia Cloud VPS instance: If you want to configure a Wikimedia Cloud VPS instance for MediaWiki with Meza
  5. Install on multiple servers: Install Meza components separately on different servers
  6. Meza/Common Test Environment (CTE)

Upgrading

edit

From Meza 35.x

edit

New procedure docs are needed for upgrading from Meza 35.x but initial testing shows that it can be done in the same way as before. ie. sudo meza update X.Y.Z (where X.Y.Z is the version you want, e.g. 39.7.0 to get the latest version), followed by sudo meza deploy your-environment-name to deploy it.

At the time of writing, the latest version is 

Meza 39.7.0-5-g65fae07
Commit 65fae07371574094d4bc63c164f56c2450f1b62b
Mediawiki EZ Admin

From Meza 31.x

edit

You should do a two-phase upgrade to get to the 35.x LTS version, then another upgrade to get to the 39.x LTS version.

Run sudo meza update 35.23.0 (35.23.0 is the last 35.x release). Then deploy it with sudo meza deploy your-environment-name.

After testing, repeat this procedure for a 39.x tag.

If you have an older version of Meza

edit

If you have an older version, see Meza/Upgrade from Meza 27.x

Autodeployer

edit

You can define a version of Meza to use in your config, and by changing your config you can automatically upgrade Meza. See more about Autodeployer.

Usage

edit

After install you'll have a fully functional MediaWiki wiki farm installation with VisualEditor, CirrusSearch, Semantic MediaWiki, and many other extensions. With your new installation, you can do the following:
