MediaWiki-Vagrant/pl





MediaWiki-Vagrant is a portable MediaWiki development environment. It consists of a set of configuration scripts for Vagrant and VirtualBox that automate the creation of a virtual machine that runs MediaWiki. Since the configuration is geared towards easy development rather than security, MediaWiki-Vagrant is not recommended for publicly accessible wikis.

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.

System requirements

 * CPU
 * 64-bit x86 processor


 * OS
 * Linux, macOS, or Windows


 * Memory
 * At least 4 GiB RAM total on your system, preferably 8 GiB or more, in order to run both the host operating system and the VM. Do not attempt to run on a system with only 2 GiB RAM, it will eventually fail.


 * Disk
 * For complex installations you must have 10-12 GB free on the primary drive (/home partition for Linux, C: drive for Windows). Note in particular that the VM disk images will be stored under your home directory by default.


 * Network
 * Active network connection with sufficient bandwidth to download Debian Linux updates and MediaWiki source code


 * Time for setup
 * 20 minutes to 2 hours, depending on conditions and if you have any troubles

Quick start
(If you are installing MediaWiki-Vagrant from the USB distribution, follow the steps in the README rather than the first five steps.)


 * 1) Get Git
 * 2) (Linux only) Install NFS if it is not already installed. In Ubuntu, use  . Fedora usually come with NFS installed; if not run.
 * 3) Get VirtualBox
 * 4) Get the latest Vagrant
 * 5) Get the code and create your machine:
 * ( This will clone into your user home directory. )
 * When prompted, enter your Gerrit user name (recommended), or just press Enter.
 * If you want to use a release branch instead of the latest version, you can specify it now with
 * 1) Enable additional MediaWiki features, e.g.:
 * 2) When Vagrant is done configuring your machine, issue the command , or browse to http://dev.wiki.local.wmftest.net:8080/ to find your MediaWiki instance. You can login with user Admin and password vagrant.

If you run Windows
Get Git for Windows and run the  commands in its Git Bash shell. Instead of, run   from a   shell.

If using the WSL Linux-compatible shell on Windows 10: run commands with  instead of. Run  instead of , which does not work in the Linux bash shell.

The account running Vagrant will probably need the "Create Symbolic Links" permission (the easy way to achieve that is running as administrator).

Troubleshooting startup
If your issues are not answered here, IRC is a good option, specifically the channel.


 * Sometimes you can fix broken installations (e.g. one saying "No wiki found..." by running  which will rebuild the virtual machine without repeating the most time-consuming parts of the installation process.

Any host
vagrant up --provider=virtualbox
 * You can try installing the versions of VirtualBox and Vagrant that your Linux distribution provides. If you're running recent Debian or Ubuntu, try sudo apt-get install virtualbox vagrant to install the packages for VirtualBox and Vagrant.
 * If you get errors from vagrant up, instead install the most recent versions of VirtualBox and Vagrant.
 * If you run into error message like "Couldn't open file $CLONED_REPOSITORY/trusty-cloud", try the following command:
 * If you got any puppet errors you might need to init puppet submodules, on vagrant directory run git submodule update --init
 * Use http://127.0.0.1:8080/info.php to check that Apache/PHP is up and running.

You might want to compare the output of the initial run of vagrant up in your terminal with this sample. The initial setup may take a long time; if it seems to hang somewhere but there are no errors, just give it a while. For example:
 * If you get warnings that your VirtualBox Guest Additions are the wrong version, you can try installing the vagrant-vbguest plugin which updates them automatically.
 * Vagrant rarely loses pairing with your VM. This thread discusses some ways to work around it (e.g. attaching old VM harddrive to the new profile)
 * Make sure that  repository is up to date:
 * Make sure that you have enabled virtualization in the BIOS. Sometimes this is under the Security settings.
 * Make sure your language encoding settings are UTF-8. If you get "invalid byte sequence in US-ASCII", try (re)setting your LANG and LC_ALL environment variables to something suitable.

Windows-specific
To turn Hyper-V back on set it back to auto instead of off This will get VirtualBox working, but will prevent you from using any Hyper-V VMs you may have, such as Windows Phone emulators. This may be unstable.
 * If you are on Windows and you get "guest machine entered an invalid state" - "poweroff", try downloading a 4.3.15 build of VirtualBox (there is a known problem with 4.3.14 on Windows). If that does not help, make sure you enable Hardware Virtualization Technology (VT-x or AMD-V) in BIOS. Hardware Virtualization is required. It is not an optional performance enhancement. (Some laptops require you to remove the power cable and battery for 30 seconds )
 *  VirtualBox is incompatible with Microsoft's Hyper-V.  If you have Hyper-V enabled – which may be the default if you have installed Visual Studio – you'll get the above errors trying to boot up a VM in VirtualBox. There are three possibilities:
 * In command prompt, run bcdedit /set hypervisorlaunchtype off to turn off Hyper-V and reboot.
 * Disable Hyper-V through 'Add/Remove Windows Features' in Control Panel and reboot.
 * or, use the Hyper-V provider for Vagrant instead of VirtualBox.

Mac-specific

 * NFS errors To avoid NFS errors, while installing, ensure the firewall will accept connections: Apple > System Preferences > Security & Privacy > Firewall > Firewall Options. You will need to UNcheck "Block all incoming connections" and probably also UNcheck "Enable stealth mode" in order to accept the following: netbiosd, nfsd, rpc.lockd, rpc.rquotad, rpcbind, VBoxHeadless. Note, you may need to restart your computer and change the status to "Allow incoming connections" during a couple s. After installation, you may be able to re-check "Block all incoming connections and "Enable stealth mode" now that the firewall rules have been updated.
 * Alternatively you can turn off NFS shares via

Debian and Ubuntu
You need to set up your computer as an "NFS server", see e.g., Ubuntu instructions. On Debian, sudo apt-get install nfs-kernel-server will work; you may need to  as well. ''' Note that Debian's NFS server will not start without an entry in. ''' If  doesn't show "nfs" services running, this is likely what's going on. Adding your home directory as the last line in  and then /etc/init.d/nfs-kernel-server restart will usually be good enough to get you past this chicken-and-egg problem.
 * MediaWiki-Vagrant uses NFS to share some folders with the host machine (your computer).
 * The NFS shares used by MediaWiki-Vagrant cannot be run from an encrypted directory, as may be the case if you are running on Ubuntu and using an encrypted home directory. To run MediaWiki-Vagrant, you can either:
 * Move the MediaWiki-Vagrant directory to an unencrypted volume (e.g., ) before running
 * Alternatively, you can turn off NFS shares via
 * NFS setup seems to get stuck sometimes (initial  hangs at "Mounting NFS shared folders"). Restarting the NFS daemon on the host helps. (See #5802.)
 * If you are getting port forwarding errors saying the ports are in use, you may need to open up VirtualBox, entirely remove the virtual machine, and try again.
 * may tell you that "The executable 'bsdtar' Vagrant is trying to run was not found in the PATH variable." You can fix this on Ubuntu with.
 * On Ubuntu with Secure Boot enabled, you will have a difficult time installing VirtualBox. Your machine may give you guff when you run . If it does, you can rectify the situation by signing the associated kernel module. Step-by-step instructions can be found in this askubuntu post.

Fedora

 * If you get Network 10.11.12.13 is not available. after running, disable SELinux via   or fix your SELinux setup.
 * If you get The provider for this Vagrant-managed machine is reporting that it is not yet ready for SSH. after running, make sure to explicitly set the provider, for example via   followed by
 * If you get mount.nfs: mount to NFS server '10.11.12.13:download-directory/vagrant' failed: RPC Error: Unable to receive, run

Basic usage
The vagrant command-line tool on the host machine provides several subcommands for controlling your virtual machine. You've already used one: vagrant up, which turns on the virtual machine. Like most vagrant subcommands, you need to run it from the MediaWiki-Vagrant directory or one of its children. When you first run it, Vagrant will fetch a system image and set up requisite software for running MediaWiki. This can take 1–2 hours of CPU and wall clock time on a broadband connection, but it only needs to happen once. When you run vagrant up in the future, it will simply boot up the machine.

vagrant ssh starts an interactive login shell on the virtual machine. It'll log you in as the user vagrant ; root access is available to via sudo, which is passwordless. Because the virtual machine is entirely sandboxed within your computer, it is configured for convenience, not security. As a rule, whenever you encounter a password prompt, the password is.

When you log in, you should see a colorful MediaWiki banner and a few reminders of useful commands.

The command phpsh will start an interactive PHP interpreter with MediaWiki's codebase already loaded. You can type in some code, hit 'enter', and the code will be evaluated immediately. If you start a line with '=', its computed value will be pretty-printed. Type ? for quick help or help start for additional instructions.

The  folder corresponds to the MediaWiki-Vagrant folder on your host machine, and its contents is shared. MediaWiki's code is installed in. This allows you to use your normal editor environment on your host machine to edit the MediaWiki code that runs on your virtual machine.

Updating
Use vagrant git-update to keep your git repositories, external libraries, and database schema up to date. This command is equivalent to running


 * 1) git pull in   and all extension and skin directories
 * 1) composer update to ensure that the latest Composer-managed libraries are available
 * 1) finally the   script.

You should also occasionally (or when needed for a new feature) update MediaWiki-Vagrant itself, which vagrant git-update does not include. Run:

… in your MediaWiki-Vagrant root directory. This will take effect when you run:

You can run that command immediately after you run git pull, or sometime after.

Log out of your virtual machine by typing logout or by pressing Ctrl. Now that you're back in a standard command prompt, you can run vagrant halt to shut down the virtual machine and vagrant up to bring it back up. vagrant destroy will delete the virtual machine's files; this command is useful if you want to return your instance to a pristine state. (You'll need to follow up with vagrant up to provision a fresh instance.)

Using roles
MediaWiki-Vagrant sets up a basic MediaWiki instance by default, but it also knows how to configure a range of complementary software, including some popular MediaWiki extensions and their dependencies. These optional software stacks are collectively known as 'roles', and MediaWiki-Vagrant offers an easy and powerful command-line interface for managing them.

Watch a short screencast demonstrating how to use roles. Roles has more information about some roles.

If you add many roles, you may need to increase memory available to the Vagrant VM. In particular, setting up the "browsertests" role involves compiling the  ruby Gem which is a memory-hungry task; if it fails try freeing some memory in the VM or increasing its memory allocation.

See the section Authoring roles below if you're interested in adding roles to MediaWiki-Vagrant.

centralauth
There are some roles that require special attention, centralauth role does not run db migrations automatically via puppet and requires running those by hand. If you get errors on provisioning this role try to run this script on the extension and see the errors it outputs:

mwscript extensions/CentralAuth/maintenance/migrateAccount.php --username 'Admin' --auto

Once you get a more concrete error you probably need to know what migration you need to run from the ones here:

extensions/CentralAuth/db_patches

wikidata
A simple  would fail. Here is a complete set of commands to make the Wikidata role up and running.

Log out from Vagrant, then you can happily run:

Note that the first provision may complain, thus looking like a failure. However, if you run a second provision, you will see that everything goes fine.

You may then point your browser to http://wikidata.wiki.local.wmftest.net:8080/. To create a new wikidata item load http://wikidata.wiki.local.wmftest.net:8080/wiki/Special:NewItem and to create a new property navigate to http://wikidata.wiki.local.wmftest.net:8080/wiki/Special:NewProperty

How to import a Wikidata dump
The Vagrant command, which imports an XML file into MediaWiki, does not handle wikis other than the default one (see T183274). You need to run the  script inside the Vagrant box.

Here is the procedure to import XML dumps.


 * download the  chunks. For instance:


 * enable the import of Wikibase entities (see phab:T72898). Append the following line to your :


 * the following BASH script can help you monitor the process. You can paste it in a  file. Note that the highlighted line calls the actual import script:


 * log into the Vagrant box and run the script. Debug messages should show up there:


 * you can follow the progress log from outside the Vagrant box:

Local MediaWiki core copy
Sometimes you may want to start over from scratch by removing the entire vagrant directory or cleaning out the vagrant/mediawiki directory. In order to speed up the vagrant provisioning process, you may want to consider keeping a local, updated clone of the MediaWiki core that you copy into vagrant/mediawiki.

for example, assuming you are cloning MediaWiki repos into ~/projects/mediawiki/ :

Update cloned repos
Update the cloned repos as often as possible/necessary.

Or to update all cloned repos:

Vagrant reload
If you change configuration (e.g. vagrant_ram, your VM/MediaWiki website freezes, or you experience a problem, vagrant reload may resolve it. This will restart your guest.  Some roles also require reloading, which should happen automatically.

When to enable roles
Enable roles only once you've successfully run your first vagrant up.

Note that vagrant destroy will not reset the enabled roles. Be sure to disable all roles after running vagrant destroy, then run vagrant up. Then you can re-enable any roles and run vagrant provision.

Vagrant behind proxy
If you are behind a proxy, Vagrant might throw some errors. You can install vagrant-proxyconf. It’s a plugin that allows your virtual machine to use specified proxies. This is a quick set up guide. For a detailed documentation you may check here.

Install the plugin:

To configure proxy settings for all pieces of software on all vagrant VMs, add the following lines to your  (default  ).

Replace the addresses with the IP and port number of your proxy server. Use the config.proxy.no_proxy option to list out all the sites/domains for which you might want to bypass proxy. For example,

Now when you run a vagrant up, there shouldn’t be any warnings.

To disable the plugin, set config.proxy.enabled to false or empty string (""). You can also disable it for specific applications. For example,

MediaWiki-Vagrant prep
You may want to consider using a shell script such as mw-vagrant-prep to prepare a directory for a MediaWiki-Vagrant install.

Provisioning
You can debug the provisioning process by running

PHP
You can debug PHP with Xdebug. Debugging in PHP is different from other client-side debugging. Your IDE listens for incoming connections, and when you access the server with a browser, a special header instructs PHP to connect to your IDE. See MediaWiki-Vagrant/Advanced usage for further information.

Chrome

 * For Chrome users, you should get XDebug Helper, and optionally Clear Cache, HTTP headers, and Mod Headers. Configure clear cache to automatically reload after clearing, and set up keyboard shortcuts (e.g. Ctrl+R for clear&reload, Ctrl+Shift+D to switch XDebugger on/off)

Firefox

 * Firefox users should check out easy Xdebug.
 * Install and configure an xdebug-compatible IDE on your machine (Eclipse, PhpStorm, Emacs, etc.)
 * In IDE, start listening for the incoming debug connection
 * In IDE, set break point at the spot that interests you
 * Enable XDebug in the browser and navigate to your vagrant installation ( http://127.0.0.1:8080/... )

Log files
The MediaWiki logs can be found in /vagrant/logs. There are log files for Apache in /var/log/apache2/, but it seems they are not written to. The MySQL query log can be obtained by issuing SET GLOBAL general_log = 'ON'; in a client and then looking at /var/lib/mysql/*.log.

Running and debugging unit tests
To run the tests for ALL extensions:

To run unit tests for a single extension:

You can append path/to/tests/to/run.

Some tests may require running as the proper user to create lock files and such, hence this command runs as the "user"  that handles web requests.

For building coverage reports, see Manual:PHP unit testing/Code coverage#MediaWiki-Vagrant.

Debugging phpunit tests is a little more complex. This method is a bit hacky, but can be used until debugging remote interpreter improves (e.g. in phpStorm 8 EAP). This workaround lets you run MediaWiki unit tests from the browser.


 * Download phpunit.phar file to the root of your vagrant directory.
 * Create a php file  in the root of the   directory. Do not commit this file to the repository. Paste the following code into it:


 * In the above file, change argv parameter to the name of your test file
 * Apache maps the root of the MediaWiki directory to . So navigate to http://127.0.0.1:8080/w/unittest.php to run this file
 * Follow #Debugging instructions to attach your debugger

Running browser tests
See.

This link is pointing to deprecated documentation, someone who knows more about testing MediaWiki should update:

Pushing commits
If you're using MediaWiki-Vagrant for development you'll probably want to push some commits to MediaWiki core or an extension's repository using git review. By default, all remotes point to the  URLs. To avoid overriding this on a case by case basis, run:

$ git config --global url."ssh:// @gerrit.wikimedia.org:29418/".insteadOf "https://gerrit.wikimedia.org/r/"

You also need to have your ssh keys in.

Gerrit
To submit changes, use  to navigate to your extensions folder. Then follow the instructions on submitting a patch via gerrit.

Troubleshooting

 * Check PHP version and settings
 * http://127.0.0.1:8080/info.php


 * Edit LocalSettings.php?
 * First, check that there is no role ( vagrant list-roles ) that already does what you need. If not, create a file in  directory. See README and 00-debug.php-example file.


 * Update MediaWiki code?
 * The easiest is to use  from the host.  Or, to just update the code without dependencies, you can use regular git ,  , etc. commands in   and   directories. You can run these commands on the virtual machine, but the file access will be faster on the host machine. MediaWiki-Vagrant pulls code from git master when you initially set up and/or add a role, but doesn't automatically update code after that.


 * Run MediaWiki PHP interpreter
 * ssh to vagrant and run . You might need to run it with


 * Run MediaWiki SQL interpreter
 * ssh to vagrant and run . You might need to run it with

''NN packages can be updated. NN updates are security updates.'' In vagrant ssh:
 * Update virtual machine software packages?
 * does not update system packages in the VM. When you connect with vagrant ssh the login message will inform that you:
 * to update all packages, enter
 * for "automatic installation of security (and other) upgrades", similar to Cloud VPS instances, enter
 * to update to the same packages that are on production WMF servers... TODO


 * Customize Vagrant
 * You should never need to change Vagrantfile directly. There are several aspects of vagrant you can customize:
 * Core settings (git user, ports, ram, ip, port forwarding) can be customized via .settings.yaml file. See  and   for instructions. So for example you may run   to enable port forwarding from host:1234 to guest:80.
 * Perform additional steps after Vagrantfile load by creating a file called Vagrantfile-extra.rb and placing it in the same folder as Vagrantfile - it will be automatically loaded. In case of conflict, values in the 'extra' file will supersede values in this file. See example in support/ directory.


 * Add custom Puppet code?
 * This is ideal if you want to work on your own MediaWiki site locally and let the MediaWiki-Vagrant install your dependencies for you. It's ideal if you have your own fork.  There is a distinction between a role and this use case. Roles are meant to be installed in any order and without breaking. If your fork needs different calls and get in trouble with roles, create your own class and call what you need, including roles.


 * To do so, place your custom puppet code in  with your own class, like so:

To apply your class, add it to the "classes" key in. You can create the file if it doesn't exist.

Then run  to apply the change via Puppet.


 * Update MediaWiki-Vagrant itself?
 * (For example, to use new roles.) In a terminal, change to the vagrant directory on the host computer and enter a regular git command such as . You will typically want to run   after updating to apply any new puppet changes to your virtual machine.


 * Run GUI applications on the virtual machine?
 * If you have an X server installed, SSH into the virtual machine using  to enable X forwarding. (Mac users should update to the latest version of XQuartz.)


 * As an alternative, you can run the virtual machine in GUI mode, which allows you to interact with the VM as though it had a physical display. To enable GUI mode, create a file called  in the root repository folder, with this as its content:


 * Save the file and run  followed by  . The virtual machine's display will appear in a window on your desktop.


 *  Adjust the resources allocated to the VM?
 * If you'd like to allocate more or less CPU / RAM to the VM, see  for instructions.

Alternatively, you can do it by creating Vagrantfile-extra.rb (see support/ dir for an example):


 * Change the editor used for git commit messages?


 * Setup a custom hostname?
 * Go to Horizon, choose Web Proxies, and enter a DNS hostname, say &lt;hostname>

View your new wiki at " http://&lt;hostname>/wiki/ "


 * Make the custom hostname point to homepage of my vagrant role instead of wiki homepage?
 * Create a local.yaml file in the /vagrant/puppet/hieradata directory. In it, add:

Run.


 * Run a branch of MediaWiki other than master?
 * Set the "" key in .  You can create the file if it doesn't exist.

MediaWiki settings
As an alternative to managing all MediaWiki settings in a single, large file, consider grouping your configurations by component or theme, and creating a separate PHP file in   for each group. This makes it quite easy to keep your settings organized, to temporarily disable specific configurations, and to share settings with others.

MediaWiki will automatically load any PHP files in  in lexical order. You can control the order in which your configurations are set by adopting the habit of adding a two-digit prefix to each file name.

For example:

 settings.d/   ├── 10-RunFirst.php ├── 20-SomeExtension.php └── 99-RunLast.php Note that the settings files in  are automatically created and destroyed in response to your Puppet configuration. Don't put your custom settings there, because Puppet will erase or override them. Keep your custom settings files in  instead.

Vagrant flags
vagrant config --list display a list of all current Vagrant flags.

After the initial, in your vagrant directory, you can then set one of the vagrant flags that appears in the config list, e.g.

Job queue
If you're testing something that needs to churn the job queue, you may need to increase the number of job runners. Currently this is not available through LocalSettings.php, but must be set in the config file for the job runner.


 * 1) Open
 * 1) Change the value for the ' ' key from   to the desired value (say,  )
 * 1) Re-provision with
 * 1) Beware this will be a difference from the git master in your code

See instructions above for adjusting CPU core count appropriately (highly recommended for CPU-bound task such as video transcoding).

Additional storage space
By default, there is relatively little free space on the root partition within the VM. If you plan to test uploading and processing of large image and video files, this may be insufficient.

Manual steps:


 * Shut down the VM
 * Open VirtualBox Manager
 * Select the VM and go into Settings
 * Under Storage, select "Controller: SATA" and click the "Add hard disk" icon.
 * Select the default disk image type.
 * Name the disk 'VagrantImageSpace' or similar, and give it enough space (say, 80GB) -- by default the file will start small and expand to actual usage, so give as much space as you might need
 * Close out the dialogs and restart the VM
 * Run  to get a shell inside the terminal
 * Run  to set up new partitions...
 * Type,  ,  , and hit (enter) twice for default size
 * Type  to save the partition table
 * Run  to create the filesystem
 * Run  to edit the mounts list
 * Add line at end:
 * save out
 * Run  to mount the filesystem
 * Run  to set the file permissions
 * Exit the shell
 * Reboot the VM

Authoring roles
The virtual machine created by MediaWiki-Vagrant resembles Wikimedia's production environment in key respects, and it uses the same tool—Puppet—that Wikimedia's technical operations team uses to manage production servers and Wikimedia Cloud VPS instances. Puppet is a configuration management tool that provides a domain-specific language for expressing software configurations in a declarative fashion. Files containing Puppet code are called 'manifests'. When Puppet runs, it interprets the manifests you feed it and configures the machine accordingly. A Vagrant role is a set of Puppet manifests.

MediaWiki-Vagrant's Puppet codebase contains abstractions that make it easy to automate the configuration of MediaWiki extensions and related software. If you are a developer working on a software project that relates to MediaWiki, you are encouraged to submit a patch with a Puppet role for your project. Adding a Vagrant role for your project makes it easy for other developers to check out your work. Using a managed virtual machine as a development sandbox for your project reduces the chance of "works-on-my-machine" errors that often result from geographically remote developers working in incompatible environments.

The easiest way to get started with custom roles is to look at how existing roles are implemented in. These roles depend on Puppet modules in  (usually,   translates to a call to  ) and use files and templates from the other   directories. The Puppet code is generally well-documented and contains examples that demonstrate its proper usage.

Some of the more useful puppet modules are:


 * mediawiki::extension - install and configure an extension (example)
 * mediawiki::import::text - create a documentation or test page on the wiki (example: declaration, page)
 * mediawiki::import::dump - import a wiki dump (example)
 * require_package - install a system package (example)
 * exec - execute a shell command (example)

Setting up an instance on Cloud VPS
You can use MediaWiki-Vagrant in Cloud VPS to install MediaWiki on a Wikimedia Cloud VPS instance and enable MediaWiki-Vagrant roles in it.

Bugs
If you spot a bug in MediaWiki-Vagrant, please report it. First, make sure the bug is not a known Vagrant or VirtualBox bug by searching the Vagrant issue tracker on GitHub and the VirtualBox bugtracker. If it is not, go ahead and submit the bug to Wikimedia Phabricator. Clearly describe the issue and include steps to reproduce, whenever possible.
