Platform requirements:

The project is designed for the Linux operating system.

It may work on FreeBSD and Mac OS, but we don't test our application for these systems and can't guarantee stability and full functionality.

We officially support (recent versions of) these Linux distributions:

  • Ubuntu Linux
  • Debian/GNU Linux

It should work on:

  • Fedora
  • CentOs
  • RedHat

You might have some luck using these, but no guarantees:

  • MacOS X
  • FreeBSD

Gitlab does not run on Windows and we have no plans of making Gitlab compatible.

This installation guide created for Debian/Ubuntu and properly tested.

The installation consists of 6 steps:

  1. Install packages / dependencies
  2. Install ruby
  3. Install gitolite
  4. Install and configure Gitlab.
  5. Start the web front-end
  6. Start a Resque worker (for background processing)

IMPORTANT

Please make sure you have followed all the steps below before posting to the mailinglist with installation and configuration questions.

Only create a Github Issue if you want a specific part of this installation guide updated.

Also read the Read this before you submit an issue wiki page.

First 3 steps can be easily skipped with simply install script:

# Install curl and sudo 
apt-get install curl sudo

# 3 steps in 1 command :)
curl https://raw.github.com/gitlabhq/gitlabhq/master/doc/debian_ubuntu.sh | sh

Now you can go to step 4"

1. Install packages

Keep in mind that sudo is not installed for debian by default. You should install it with as root: apt-get update && apt-get upgrade && apt-get install sudo

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install -y wget curl gcc checkinstall libxml2-dev libxslt-dev sqlite3 libsqlite3-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev libmysql++-dev make build-essential zlib1g-dev libicu-dev redis-server openssh-server git-core python-dev python-pip libyaml-dev sendmail

# If you want to use MySQL:
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

2. Install ruby

wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p290.tar.gz
tar xzfv ruby-1.9.2-p290.tar.gz
cd ruby-1.9.2-p290
./configure
make
sudo make install

3. Install gitolite

Create user for git:

sudo adduser \
  --system \
  --shell /bin/sh \
  --gecos 'git version control' \
  --group \
  --disabled-password \
  --home /home/git \
  git

Create user for gitlab:

# ubuntu/debian
sudo adduser --disabled-login --gecos 'gitlab system' gitlab

Add your user to git group:

sudo usermod -a -G git gitlab

Generate key:

sudo -H -u gitlab ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa

Get gitolite source code:

cd /home/git
sudo -H -u git git clone git://github.com/gitlabhq/gitolite /home/git/gitolite

Setup:

sudo -u git sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" >> /home/git/.profile'
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; /home/git/gitolite/src/gl-system-install"
sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
sudo chmod 0444 /home/git/gitlab.pub

sudo -u git -H sed -i 's/0077/0007/g' /home/git/share/gitolite/conf/example.gitolite.rc
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gl-setup -q /home/git/gitlab.pub"

Permissions:

sudo chmod -R g+rwX /home/git/repositories/
sudo chown -R git:git /home/git/repositories/
sudo chown gitlab:gitlab /home/git/repositories/**/hooks/post-receive

CHECK: Logout & login again to apply git group to your user

# clone admin repo to add localhost to known_hosts
# & be sure your user has access to gitolite
sudo -u gitlab -H git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin 

# if succeed  you can remove it
sudo rm -rf /tmp/gitolite-admin

IMPORTANT! If you cant clone gitolite-admin repository - DONT PROCEED INSTALLATION

4. Install gitlab and configuration. Check status configuration.

sudo gem install charlock_holmes
sudo pip install pygments
sudo gem install bundler
cd /home/gitlab
sudo -H -u gitlab git clone -b stable git://github.com/gitlabhq/gitlabhq.git gitlab
cd gitlab

sudo -u gitlab mkdir tmp

# Rename config files
sudo -u gitlab cp config/gitlab.yml.example config/gitlab.yml

Select db you want to use

# SQLite
sudo -u gitlab cp config/database.yml.sqlite config/database.yml

# Or 
# Mysql
sudo -u gitlab cp config/database.yml.example config/database.yml
# Change username/password of config/database.yml  to real one

Install gems

sudo -u gitlab -H bundle install --without development test --deployment

Setup DB

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

Checking status:

sudo -u gitlab bundle exec rake gitlab:app:status RAILS_ENV=production


# OUTPUT EXAMPLE
Starting diagnostic
config/database.yml............exists
config/gitlab.yml............exists
/home/git/repositories/............exists
/home/git/repositories/ is writable?............YES
remote: Counting objects: 603, done.

Can clone gitolite-admin?............YES
UMASK for .gitolite.rc is 0007? ............YES

If you got all YES - congrats! You can go to next step.

5. Server up

Application can be started with next command:

# For test purposes 
sudo -u gitlab bundle exec rails s -e production

# As daemon
sudo -u gitlab bundle exec rails s -e production -d

You can login via web using admin generated with setup:

admin@local.host
5iveL!fe

6. Run resque process (for processing queue).

# Manually
sudo -u gitlab bundle exec rake environment resque:work QUEUE=* RAILS_ENV=production BACKGROUND=yes

# Gitlab start script
./resque.sh

**Ok - we have a working application now. ** **But keep going - there are some thing that should be done **

Nginx && Unicorn

Install Nginx

sudo apt-get install nginx

Unicorn

cd /home/gitlab/gitlab
sudo -u gitlab cp config/unicorn.rb.orig config/unicorn.rb
sudo -u gitlab bundle exec unicorn_rails -c config/unicorn.rb -E production -D

Edit /etc/nginx/nginx.conf. In the http section add:

upstream gitlab {
    server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.socket;
}

server {
    listen YOUR_SERVER_IP:80;         # e.g., listen 192.168.1.1:80;
    server_name YOUR_SERVER_FQDN;     # e.g., server_name source.example.com;
    root /home/gitlab/gitlab/public;
    
    # individual nginx logs for this gitlab vhost
    access_log  /var/log/nginx/gitlab_access.log;
    error_log   /var/log/nginx/gitlab_error.log;
    
    location / {
        # serve static files from defined root folder;.
        # @gitlab is a named location for the upstream fallback, see below
        try_files $uri $uri/index.html $uri.html @gitlab;
    }
    
    # if a file, which is not found in the root folder is requested, 
    # then the proxy pass the request to the upsteam (gitlab unicorn)
    location @gitlab {
      proxy_redirect     off;
      
      # you need to change this to "https", if you set "ssl" directive to "on"
      proxy_set_header   X-FORWARDED_PROTO http;
      proxy_set_header   Host              $http_host;
      proxy_set_header   X-Real-IP         $remote_addr;
    
      proxy_pass http://gitlab;
    }
}

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

Restart nginx:

/etc/init.d/nginx restart

Create init script in /etc/init.d/gitlab:

#! /bin/bash
### BEGIN INIT INFO

NAME=unicorn
DESC="Gitlab service"
PID=/home/gitlab/gitlab/tmp/pids/unicorn.pid
RESQUE_PID=/home/gitlab/gitlab/tmp/pids/resque_worker.pid

case "$1" in
  start)
        CD_TO_APP_DIR="cd /home/gitlab/gitlab"
        START_DAEMON_PROCESS="bundle exec unicorn_rails $DAEMON_OPTS"
        START_RESQUE_PROCESS="./resque.sh"

        echo -n "Starting $DESC: "
        if [ `whoami` = root ]; then
          sudo -u gitlab sh -l -c "$CD_TO_APP_DIR > /dev/null 2>&1 && $START_DAEMON_PROCESS && $START_RESQUE_PROCESS"
        else
          $CD_TO_APP_DIR > /dev/null 2>&1 && $START_DAEMON_PROCESS && $START_RESQUE_PROCESS
        fi
        echo "$NAME."
        ;;
  stop)
        echo -n "Stopping $DESC: "
        kill -QUIT `cat $PID`
        kill -QUIT `cat $RESQUE_PID`
        echo "$NAME."
        ;;
  restart)
        echo -n "Restarting $DESC: "
        kill -USR2 `cat $PID`
        echo "$NAME."
        ;;
  reload)
        echo -n "Reloading $DESC configuration: "
        kill -HUP `cat $PID`
        echo "$NAME."
        ;;
  *)
        echo "Usage: $NAME {start|stop|restart|reload}" >&2
        exit 1
        ;;
esac

exit 0

Adding permission:

sudo chmod +x /etc/init.d/gitlab

Gitlab autostart:

sudo update-rc.d gitlab defaults

Now you can start/restart/stop gitlab like:

sudo /etc/init.d/gitlab restart
