Packages / Dependencies

Install the required packages:

sudo apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl git-core openssh-server redis-server postfix checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev

Make sure you have the right version of Python installed.

Install Python

sudo apt-get install python

Make sure that Python is 2.5+ (3.x is not supported at the moment)

python --version

If it’s Python 3 you might need to install Python 2 separately

sudo apt-get install python2.7

Make sure you can access Python via python2

python2 --version

If you get a “command not found” error create a link to the python binary

sudo ln -s /usr/bin/python /usr/bin/python2

Ruby

Download and compile it:

mkdir /tmp/ruby && cd /tmp/ruby
curl --progress http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p392.tar.gz | tar xz
cd ruby-1.9.3-p392
./configure
make
sudo make install

Install the Bundler Gem:

sudo gem install bundler

System Users

Create a git user for Gitlab:

sudo adduser --disabled-login --gecos 'GitLab' git

GitLab shell

GitLab Shell is a ssh access and repository management software developed specially for GitLab.

Login as git

sudo su git

Go to home directory

cd /home/git

Clone gitlab shell

git clone https://github.com/gitlabhq/gitlab-shell.git
cd gitlab-shell
cp config.yml.example config.yml

Edit config and replace gitlab_url with something like ‘http://domain.com/’

vim config.yml

Do setup

./bin/install

Database

Login to MySQL

mysql -u root -p

Create a user for GitLab. (change $password to a real password)

mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';

Create the GitLab production database

mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;

Grant the GitLab user necessary permissopns on the table.

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';

Quit the database session

mysql> \q

GitLab

We’ll install GitLab into home directory of the user “git”

cd /home/git

Clone the Source

Clone GitLab repository

sudo -u git -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab

Go to gitlab dir

cd /home/git/gitlab

Checkout to stable release

sudo -u git -H git checkout 5-0-stable

Note: You can change 5-0-stable to master if you want the bleeding edge version, but do so with caution!

Configure it

cd /home/git/gitlab

Copy the example GitLab config

sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml

Make sure to change “localhost” to the fully-qualified domain name of your
host serving GitLab where necessary

sudo -u git -H vim config/gitlab.yml

Make sure GitLab can write to the log/ and tmp/ directories

sudo chown -R git log/
sudo chown -R git tmp/
sudo chmod -R u+rwX  log/
sudo chmod -R u+rwX  tmp/

Create directory for satellites

sudo -u git -H mkdir /home/git/gitlab-satellites

Create directory for pids and make sure GitLab can write to it

sudo -u git -H mkdir tmp/pids/
sudo chmod -R u+rwX  tmp/pids/

Copy the example Unicorn config

sudo -u git -H cp config/unicorn.rb.example config/unicorn.rb

Important Note: Make sure to edit both files to match your setup.

Configure GitLab DB settings

Mysql

sudo -u git cp config/database.yml.mysql config/database.yml

PostgreSQL

sudo -u git cp config/database.yml.postgresql config/database.yml

Make sure to update username/password in config/database.yml.

Install Gems

cd /home/git/gitlab
sudo gem install charlock_holmes --version '0.6.9'

For MySQL (note, the option says “without”)

sudo -u git -H bundle install --deployment --without development test postgres

Or for PostgreSQL

sudo -u git -H bundle install --deployment --without development test mysql

Initialise Database and Activate Advanced Features

sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production

Install Init Script

Download the init script (will be /etc/init.d/gitlab):

sudo curl --output /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlab-recipes/master/init.d/gitlab
sudo chmod +x /etc/init.d/gitlab

Make GitLab start on boot:

sudo update-rc.d gitlab defaults 21

Check Application Status

Check if GitLab and its environment are configured correctly:

sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

To make sure you didn’t miss anything run a more thorough check with:

sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations on successfully installing GitLab! However there are still a few steps left.

Start Your GitLab Instance

sudo service gitlab start

Nginx

Note: If you can’t or don’t want to use Nginx as your web server, have a look at the Advanced Setup Tips section.

Installation

sudo apt-get install nginx

Site Configuration

Download an example site config:

sudo curl --output /etc/nginx/sites-available/gitlab https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab
sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab

Make sure to edit the config file to match your setup:

Change YOUR_SERVER_IP and YOUR_SERVER_FQDN to the IP address and fully-qualified domain name of your host serving GitLab

sudo vim /etc/nginx/sites-available/gitlab

Restart

sudo service nginx restart

Done!
