MediaWiki-Vagrant is a portable MediaWiki development environment. It consists of a set of configuration scripts that automate the creation of a virtual machine that runs MediaWiki.

The virtual machine that MediaWiki-Vagrant creates makes it easy to learn about, modify, and improve MediaWiki's code: useful debugging information is displayed by default, and various developer tools are set up specifically for inspecting and interacting with MediaWiki code, including a powerful debugger and an interactive interpreter. Best of all, because the configuration is automated and contained in a virtual environment, mistakes are easy to undo.


You'll need to install recent versions of Vagrant and VirtualBox.

(Note that experimental support for Parallels, LXC, libvirt (KVM/QEMU), VMWare Fusion, and Microsoft Hyper-V providers exists. See support/ support/ or support/ for details on the former three.)

To check your Vagrant version, run

 vagrant --version

in a directory without a Vagrantfile (e.g. in your home directory). * You must have a 64-bit processor (although your host OS can be 32-bit).

Hardware virtualization extensions must be enabled in your host computer BIOS. The BIOS setting is usually in the “Chipset”, “Processor”, “CPU”, or “Security Settings” menu and may be labeled as “VT-x”, “Intel Virtualization Technology”, “Virtualization Extensions”, “Vanderpool” “AMD-V” or various other names depending on the OEM and system BIOS. * (Optional) For better performance on non-Windows hosts, install NFS. For Debian-based systems (including Ubuntu), run:

sudo apt-get install nfs-kernel-server portmap

You can optionally configure sudo not to prompt you for the password when doing operations related to this NFS service. See

Next, you'll need a copy of the mediawiki-vagrant project files.

If you've downloaded the zip file or tarball, you will need to extract it to a directory of your choice. Once you do that, open up a terminal or a command-prompt, and change your working directory to the location of the extracted (or git-cloned) files.

If you have cloned the git repository you will also need to clone the submodules with:

git submodule update --init --recursive

Run the appropriate setup script for your platform. For Windows, run setup.bat. For Linux and OS X, run Some extra Vagrant plugins, including the bundled mediawiki-vagrant plugin, will be installed.

From there, run vagrant up to provision and boot the virtual machine.

You'll now have to wait a bit, as Vagrant needs to retrieve the base image from Canonical, retrieve some additional packages, and install and configure each of them in turn.

If it all worked, you should be able to browse to and see the main page of your MediaWiki instance.


To access a command shell on your virtual environment, run vagrant ssh from the root mediawiki-vagrant directory or any of its subdirectories.

From there, run mwrepl to interactively evaluate PHP code in a MediaWiki context, or mysql to get an authenticated SQL shell on your wiki's database. If you have multiple wikis enabled, you can run e.g. mwrepl frwiki.

The admin account on MediaWiki is admin / vagrant.


When the vagrant Virtual Machine is running, it will periodically run Puppet (an open source configuration management tool) to update its configuration, which keeps various software packages up to date. To avoid clobbering any changes you may have made to MediaWiki's source code, Puppet will not update MediaWiki.

To pick up other changes to the install, on the host computer in the directory with the vagrant files run git pull --rebase and then vagrant reload. The latter will restart the VM.


You can add roles to MediaWiki-Vagrant! A 'role' represents a set of software configurations required for giving this machine some special function. Mediawiki-Vagrant has several commands to manage enabled roles. See vagrant roles -h for help on usage.

If you'd like to use the Mediawiki-Vagrant codebase to describe a development environment that you could then share with other developers, you should do so by adding a role file to puppet/modules/role/manifests/ and submitting it as a patch to the Mediawiki-Vagrant project.
