Phabricator Ubuntu Installation Guide

Phabricator Ubuntu Installation Guide

Phabricator Ubuntu Installation Guide

This is a supplement to the official Phabricator Installation Guide, because their guide will leave you with all kinds of permission and config errors and ~15,000 setup issues on startup.

Install bonus packages:

# apt-get install mercurial subversion python-pygments sendmail imagemagick

Create necessary users and add phd-user to sudoers:

# adduser phd --home /home/phd
# adduser phd sudo
# adduser git

And create repo directory if phabricator will be hosting repos:

# mkdir /var/repo
# chown -R phd /var/repo
# chgrp -R phd /var/repo

Install phabricator:

su phd
cd /home/phd
wget http://www.phabricator.com/rsrc/install/install_ubuntu.sh
bash install_ubuntu.sh

Recommended Phabricator Configurations to set:

cd /home/phd/phabricator

# Generally acceptable settings:
./bin/config set mysql.pass <MYSQL_ROOT_PASSWD>
./bin/config set phabricator.base-uri 'http://phabricator.mydomain.net/'
./bin/config set phd.user phd
./bin/config set environment.append-paths '["/usr/lib/git-core"]'
./bin/config set diffusion.ssh-user git
./bin/config set pygments.enabled true

# for local-disk file storage only:
mkdir /home/phd/phabricator-files
chmod -R 755 /home/phd/phabricator-files
./bin/config set storage.local-disk.path /home/phd/phabricator-files

# Set true if you want to allow public http cloning:
./bin/config set policy.allow-public true
# Set to true if you want to allow http pushes
./bin/config set diffusion.allow-http-auth false
# You most likely want prototype apps, they are very useful:
./bin/config set phabricator.show-prototypes true
# You may want this true, depending on your workflow:
./bin/config set differential.require-test-plan-field false

# recommended silliness-enabling settings:
./bin/config set files.enable-imagemagick true
./bin/config set remarkup.enable-embedded-youtube true

This needs to be appended to /etc/sudoers (NOTE: verify your binary locations):

git ALL=(phd) SETENV: NOPASSWD: /usr/bin/git-upload-pack, /usr/bin/git-receive-pack, /usr/bin/hg, /usr/bin/svnserve
www-data ALL=(phd) SETENV: NOPASSWD: /usr/bin/git-upload-pack, /usr/lib/git-core/git-http-backend, /usr/bin/hg

Apache Configuration:

First verify that apache is displaying a default page on port 80, then setup apache configuration file (see examples below) and enable phabricator site:

# cat /etc/apache2/sites-available/phabricator.conf
<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName phabricator.mydomain.net
        ServerAlias phabricator.mydomain.net
        ServerAdmin webmaster@example.com

        DocumentRoot /home/phd/phabricator/webroot

        RewriteEngine on
        RewriteRule ^/rsrc/(.*)     -                       [L,QSA]
        RewriteRule ^/favicon.ico   -                       [L,QSA]
        RewriteRule ^(.*)$          /index.php?__path__=$1  [B,L,QSA]

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
        <Directory "/home/phd/phabricator/webroot">
                Require all granted

And here is an example of an HTTPS-enabled phabricator conf:

<IfModule mod_ssl.c>
        <VirtualHost *:80>
                ServerName phabricator.mydomain.net
                Redirect permanent / https://phabricator.mydomain.net
        <VirtualHost *:443>

                # Change this to the domain which points to your host.
                ServerName phabricator.mydomain.net
                SSLEngine on
                SSLCertificateKeyFile /etc/ssl/private/phabricator.key
                SSLCertificateFile /etc/ssl/certs/phabricator_mydomain.net.crt
                SSLCertificateChainFile /etc/ssl/certs/phabricator_mydomain.net.ca-bundle
                SSLProtocol All -SSLv2 -SSLv3

                # Change this to the path where you put 'phabricator' when you checked it
                # out from GitHub when following the Installation Guide.
                # Make sure you include "/webroot" at the end!
                DocumentRoot /home/phd/phabricator/webroot

                RewriteEngine on
                RewriteRule ^/rsrc/(.*)     -                       [L,QSA]
                RewriteRule ^/favicon.ico   -                       [L,QSA]
                RewriteRule ^(.*)$          /index.php?__path__=$1  [B,L,QSA]
                <Directory "/home/phd/phabricator/webroot">
                        Require all granted

Make sure mod_php and mod_rewrite are enabled, and mod_ssl if you intend to set up SSL

# a2dissite 000-default
# a2ensite phabricator
# service apache2 restart

Configure mysql and storage:

Add these new lines to /etc/mysql/my.cnf under the [mysqld] heading:

ft_boolean_syntax=' |-><()~*:""&^'

This new line should be about 40% of the memory of the box:


And also adjust max_allowed_packet to 32M (this line will already exist)

max_allowed_packet      = 32M

Restart mysql and run phabricator storage upgrade:

service restart mysql
./bin/storage upgrade

Configure php:

Adjust the following fields in /etc/php5/apache2/php.ini

post_max_size = 8M
date.timezone = Etc/UTC

Then restart apache

service apache2 restart

Restart phd daemons:

./bin/phd restart

Enable ssh clone & push

Change default ssh port to something other than port 22 (I like to use 2222)

# edit Port setting here
vim /etc/ssh/sshd_config
# restart sshd service
service sshd restart

Make executable ssh hook for phabricator ssh daemon

# copy ssh hook to executable location
cp /home/phd/phabricator/resources/sshd/phabricator-ssh-hook.sh /usr/lib/phabricator-ssh-hook.sh
chown root /usr/lib/phabricator-ssh-hook.sh
chmod 755 /usr/lib/phabricator-ssh-hook.sh
# Modify hook to match your system (hint: vcs-user == git)
vim /usr/lib/phabricator-ssh-hook.sh

Create phabricator ssh daemon on port 22

# Copy the examply sshd config
cp /home/phd/phabricator/resources/sshd/sshd_config.phabricator.example /etc/ssh/sshd_config.phabricator
# Edit AuthorizedKeysCommand, AuthorizedKeysCommandUser, and AllowUsers
vim /etc/ssh/sshd_config.phabricator
# Start the phabricator sshd
/usr/sbin/sshd -f /etc/ssh/sshd_config.phabricator

Now you should be able to run this command:

echo {} | ssh git@phabricator.mydomain.net conduit conduit.ping

And get output like this:


Refer to the phabricator configuration guide for next steps:

At this point, you should be able to host and clone repositories via HTTP & SSH. Refer to the Diffusion Hosting Configuration Guide for trouble-shooting.

Also see the official Phabricator Configuration Guide for additional advanced configuration steps.
