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 next Linux Distributions:

• Ubuntu
• Debian

It should work on:

• Fedora
• CentOs
• Red Hat

It can work on:

• Mac Os
• FreeBSD

It 100% wont work on Windows

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

The installation consists of 6 steps:

1. install packeges.
2. install ruby
3. install gitolite
4. install gitlab and configuration. Check status configuration.
5. server up.
6. run resque process (for processing queue).

** Before submit an installation issue - please check if you followed all steps **

---

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 http://dl.dropbox.com/u/936096/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 git-core wget curl gcc checkinstall libxml2-dev libxslt-dev sqlite3 libsqlite3-dev libcurl4-openssl-dev libreadline-dev libc6-dev libssl-dev libmysql++-dev make build-essential zlib1g-dev libicu-dev redis-server openssh-server git-core python-dev python-pip sendmail

2. Install ruby

wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p290.tar.gz
tar xfvz 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 -H /home/git/gitolite/src/gl-system-install
sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
sudo chmod 777 /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/

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 git://github.com/gitlabhq/gitlabhq.git gitlab
cd gitlab

# 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 db:setup RAILS_ENV=production
sudo -u gitlab bundle exec rake db:seed_fu RAILS_ENV=production

Checking status:

sudo -u gitlab bundle exec rake gitlab_status


# 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.
remote: Compressing objects: 100% (466/466), done.
remote: Total 603 (delta 174), reused 0 (delta 0)
Receiving objects: 100% (603/603), 53.29 KiB, done.
Resolving deltas: 100% (174/174), 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

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 unicorn_rails -c config/unicorn.rb -E production -D

Edit /etc/nginx/nginx.conf. Add next code to http section:

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

server {
    listen 80;
    server_name mygitlab.com;

    location / {

        root /home/gitlab/gitlab/public;

        if (!-f $request_filename) {
            proxy_pass http://gitlab; 
            break;
        }
    }

}

mygitlab.com - change to your domain.

Restart nginx:

/etc/init.d/nginx restart

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

#! /bin/bash
### BEGIN INIT INFO
# Provides:          unicorn
# Required-Start:    $local_fs $remote_fs $network $syslog
# Required-Stop:     $local_fs $remote_fs $network $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts the unicorn web server
# Description:       starts unicorn
### END INIT INFO

DAEMON_OPTS="-c /home/gitlab/gitlab/config/unicorn.rb -E production -D"
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 $DESC: "
        if [ `whoami` = root ]; then
          sudo -u gitlab sh -c "$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`
        kill -USR2 `cat $RESQUE_PID`
        echo "$NAME."
        ;;
  reload)
        echo -n "Reloading $DESC configuration: "
        kill -HUP `cat $PID`
        kill -HUP `cat $RESQUE_PID`
        echo "$NAME."
        ;;
  *)
        echo "Usage: $NAME {start|stop|restart|reload}" >&2
        exit 1
        ;;
esac

exit 0

Adding permission:

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

When server is rebooted then gitlab must starting:

sudo update-rc.d gitlab defaults

Now you can start/restart/stop gitlab like:

sudo /etc/init.d/gitlab restart
