Phabricator/Local Dev Environment

From mediawiki.org

This page started life as User:BBearnes (WMF)'s notes from setting up a local dev environment for Phabricator, with some additions by MModell.

The hostname used here is: http://phabricator.lan/

An alternative pre-configured environment exists, which allows to use our existing deployment to spin up a working local Phab/Phorge instance via Scap. See here.

Phabricator / Phorge installation

[edit]

See Phabricator installation guide or Phorge installation guide for basics.

For stability, stick to PHP 7 and avoid distributions with PHP 8.1+ for the time being.

Install system dependency packages

[edit]
  • On Debian Bullseye:
    sudo apt install php-gd php-zip php-apcu php-mysql php-mbstring php-curl nginx php-fpm mariadb-server
    (or replace nginx with apache2 when using Apache HTTPD)
  • On Fedora:
    sudo dnf install httpd mariadb-server php php-gd php-mbstring php-mysqlnd php-opcache php-pecl-apcu-bc php-pecl-zip php-xml php-process

When using Apache, install its php module. For PHP 7: sudo apt install libapache2-mod-php7.4

Pull Wikimedia Phabricator code

[edit]
  • If not done yet, set up your SSH key in Wikimedia GitLab to git clone in the next step
  • cd ~/code/wmf/
  • git clone git@gitlab.wikimedia.org:repos/phabricator/deployment.git phab-deployment
  • cd phab-deployment/
  • git submodule init
  • git submodule update --force

Set up MySQL/MariaDB database privileges

[edit]
  • sudo systemctl start mariadb
  • sudo mariadb
  • MariaDB [mysql]> CREATE USER 'phabricator'@'localhost' IDENTIFIED BY 'password';
  • MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'phabricator'@'localhost';
  • MariaDB [mysql]> FLUSH PRIVILEGES
  • MariaDB [mysql]> Bye

Initialize database

[edit]

~/code/wmf/phab-deployment/phabricator/bin/storage upgrade --force

Configure database access

[edit]
  • ~/code/wmf/phab-deployment/phabricator/bin/config set mysql.host "localhost"
  • ~/code/wmf/phab-deployment/phabricator/bin/config set mysql.user phabricator
  • ~/code/wmf/phab-deployment/phabricator/bin/config set mysql.pass 'password'

Enable Phabricator developer mode

[edit]
  • ~/code/wmf/phab-deployment/phabricator/bin/config set phabricator.developer-mode true
  • Optionally, set a DB prefix to avoid conflicts when testing with several versions:
    ~/code/wmf/phab-deployment/phabricator/bin/config set storage.default-namespace "wmfphab"

Configure PHP

[edit]

Per http://phabricator.lan/config/issue/extension.opcache.devmode/ shown in the installed instance, make the following changes on Debian in the file php.ini. (The command php --ini locates the configuration file.) 

diff --git a/php/7.4/fpm/php.ini b/php/7.4/fpm/php.ini

Set Phabricator base URL

[edit]

~/code/wmf/phab-deployment/phabricator/bin/config set phabricator.base-uri 'http://phabricator.lan/'

Define system host

[edit]

Add to the file /etc/hosts the following line:
127.0.1.1 phabricator.lan

Configure webserver

[edit]

Note: This section only applies when using Apache HTTPD instead of Nginx:

  • Enable the two required modules: a2enmod rewrite; a2enmod php7.4
  • Create the file /etc/apache2/sites-available/001-wmfphab.conf with the following content:
<VirtualHost *>
  ServerName phabricator.lan
  DocumentRoot ~/code/wmf/phab-deployment/phabricator/webroot
<Directory "~/code/wmf/phab-deployment/phabricator/webroot">
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>
  RewriteEngine on
  RewriteRule ^/rsrc/(.*)    -                       [L,QSA]
  RewriteRule ^/favicon.ico  -                       [L,QSA] 
  RewriteRule ^/(.*)$       /index.php?__path__=/$1  [B,L,QSA]
</VirtualHost>
  • sudo ln -s /etc/apache2/sites-available/001-wmfphab.conf /etc/apache2/sites-enabled/001-wmfphab.conf
  • sudo rm /etc/apache2/sites-enabled/000-default.conf

Start webserver

[edit]

sudo systemctl start nginx
(or
sudo systemctl start apache2
when using Apache HTTPD)

Load custom Phabricator extensions

[edit]

For antivandalism, misc and translations: 

~/code/wmf/phab-deployment/phabricator/bin/config set load-libraries '["~/code/wmf/phab-deployment/libext/ava/src","~/code/wmf/phab-deployment/libext/misc/src","~/code/wmf/phab-deployment/libext/translations/src"]'

Then config is under http://phabricator.lan/config/group/ , for example http://phabricator.lan/config/group/antivandalism/

Administration, etc.

[edit]

Creating test data

[edit]

This requires developer mode, but there's a `lipsum` command: 

~/code/wmf/phab-deployment/phabricator/bin/lipsum generate tasks

Starting daemons

[edit]
~/code/wmf/phab-deployment/phabricator/bin/phd start

Auth lock

[edit]

Disallows configuring authentication methods in the user interface 

~/code/wmf/phab-deployment/phabricator/bin/auth lock

Recover access to a local account

[edit]

See https://we.phorge.it/book/phorge/article/configuring_accounts_and_registration/ , basically: 

~/code/wmf/phab-deployment/phabricator/bin/auth recover someUsername
