MediaWiki-Vagrant/ja



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.

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.

Quick start
If you are installing MediaWiki-Vagrant from the USB distribution, follow the steps in the README rather than the first four steps.   Git を入手   最新の VirtualBox を入手   Vagrant 1.5.4 を入手  Get the code and create your machine:  $ git clone https://gerrit.wikimedia.org/r/mediawiki/vagrant $ cd vagrant $ git submodule update --init --recursive $ vagrant up Running Windows? Get Git and run these commands in a Git Bash shell.  If prompted, enter your Gerrit user name (recommended), or just hit Enter. When Vagrant is done configuring your machine, browse to http://127.0.0.1:8080/ to find your MediaWiki instance. The admin password is. Linux repositories may provide older versions that are not compatible with MediaWiki-Vagrant.
 * Running Mac? 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.


 * 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  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.

git submodule update --init
 * If you're not running Windows, MediaWiki-Vagrant uses NFS to share some folders with the host machine (your computer). You need to set up your computer as an "NFS server", see e.g. Ubuntu instructions.
 * If you got any puppet errors you might need to init puppet submodules, on vagrant directory run:
 * If you have additional questions, IRC is a good option, specifically the channel.

基本的な使用法


The  command-line tool on the host machine provides several subcommands for controlling your virtual machine. You've already used one:, which turns on the virtual machine. Like most  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 takes about a hour on a broadband connection, but it only needs to happen once. When you run  in the future, it'll simply boot up the machine.

starts an interactive login shell on the virtual machine. It'll log you in as the user ; root access is available to via , 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 you may be prompted to update the version of VirtualBox Guest Additions. Updating will improve the performance and reliability of your machine, so go ahead and do it, by running.

The command  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.

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.

Use  to keep your git repositories and database schema up to date. This command is equivalent of performing  for core and all extension directories, followed by running the   script.

Log out of your virtual machine by typing  or by pressing. Now that you're back in a standard command prompt, you can run  to shut down the virtual machine and   to bring it back up. 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  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.  $ vagrant list-roles
 * 1) Display a list of available roles.

 $ vagrant enable-role role
 * 1) Turn on role for this machine.

 $ vagrant disable-role role Watch a short screencast demonstrating how to use roles. /Roles has more information about some roles.
 * 1) Turn off role for this machine.

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.

デバッグ
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.


 * 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 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/... )

Debugging Unit Tests
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 you vagrant directory.
 * Create a php file unittest.php in the root of mediawiki directory (mapped as /w on apache). Do not commit this file to the repository.


 * In the above file, change argv parameter to the name of your test file
 * Navigate to http://127.0.0.1:8080/w/unittest.php
 * Follow #Debugging instructions to attach your debugger

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. 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/"

How do I...?

 * 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 vagrant git-update from the host. Or you can use regular git fetch, pull , 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.


 * Update system software?
 * vagrant provision does not update system packages in the VM. When you connect with vagrant ssh the login message will inform you <tt>NN packages can be updated. NN updates are security updates.</tt> In vagrant ssh:
 * to update all packages, enter sudo apt-get update && apt-get upgrade
 * for "automatic installation of security (and other) upgrades", similar to labs instances, enter sudo unattended-upgrade
 * 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, ips, box name & url) can be customized via .settings.yaml file. See Vagrantfile for the description of each setting.
 * 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?
 * Place your custom Puppet manifests in . Puppet will automatically apply any .pp files that it finds in that directory.


 * 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 git pull --ff-only


 * 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, edit  file and add these values (see Vagrantfile for more settings):

Alternatively, you can do it by creating Vagrantfile-extra.rb (see support/ dir for an example):
 * Change the editor used for git commit messages?

高度な使用法
As an alternative to managing all MediaWiki settings in a single, large LocalSettings.php 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.

例:

<pre style="background-color: #efefef; border: 0; display: inline-block; font-family: Consolas, monaco, monospace; margin: 0.4em 0 1em; padding: 0.2em 0.6em;"> 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.

Authoring roles
MediaWiki-Vagrant uses Puppet to configure MediaWiki on the virtual machine. Puppet is a configuration management tool that works by providing 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. MediaWiki-Vagrant's Puppet code is located in the. These roles depend on Puppet modules in. The Puppet code is generally well-documented and contains examples that demonstrate its proper usage.

Setting up labs instances
You can use Labsvagrant to configure Wikimedia Labs machines with a given MediaWiki-Vagrant role.
