  • How to install GIT
  • Example shown below


    Important notes

    This guide is long because it covers many cases and includes all commands you need, this is one of the few installation scripts that actually works out of the box.

    Remember read documents for hardware and operating system requirements because this installation guide was created for and tested on Debian/Ubuntu operating systems. 

    The following steps have been known to work. Please use caution when you deviate from this guide. Make sure you don't violate any assumptions GitLab makes about its environment. For example many people run into permission problems because they changed the location of directories or run services as the wrong user.


    The GitLab installation consists of setting up the following components: 

    Packages / Dependencies

    1.     Ruby 

    2.     System 

    3.     Users

    4.     Database

    5.     GitLab 

    6.     Nginx

    1. Packages / Dependencies

    sudo is not installed on Debian by default. Make sure your system is up-to-date and install it.

    # run as root! 

    apt-get update -y 

    apt-get upgrade -y 

    apt-get install sudo -y


    # Install vim and set as default editor 

    sudo apt-get install -y vim 

    sudo update-alternatives --set editor /usr/bin/vim.basic

    Install the required packages (needed to compile Ruby and native extensions to Ruby gems):

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

    Make sure you have the right version of Python installed.

    # Install Python 
    sudo apt-get install -y 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
    # For reStructuredText markup language support install required package: 
    sudo apt-get install python-docutils

    Note: In order to receive mail notifications, make sure to install a mail server. By default, Debian is shipped with exim4 whereas Ubuntu does not ship with one. The recommended mail server is postfix and you can install it with:

    sudo apt-get install -y postfix

    Then select 'Internet Site' and press enter to confirm the hostname.

    2. Ruby

    The use of ruby version managers such as RVM, rbenv or chruby with GitLab in production frequently leads to hard to diagnose problems

    Remove the old Ruby 1.8 if present 

    sudo apt-get remove ruby1.8

    Download Ruby and compile it:

    mkdir /tmp/ruby && cd /tmp/ruby

    curl --progress ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p353.tar.gz | tar xz

    cd ruby-2.0.0-p353

    ./configure --disable-install-rdoc


    sudo make install

    Install the Bundler Gem:

    sudo gem install bundler --no-ri --no-rdo

    3. System Users

    Create a git user for Gitlab:

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

    4. GitLab shell

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

    # Go to home directory 
    cd /home/git
     # Clone gitlab shell 
    sudo -u git -H git clone https://github.com/gitlabhq/gitlab-shell.git 
    cd gitlab-shell 
    # switch to right version 
    sudo -u git -H git checkout v1.7.1 
    sudo -u git -H cp config.yml.example config.yml 
    # Edit config and replace gitlab_url 
    # with something like 'http://domain.com/'
     sudo -u git -H editor config.yml
    # Do setup 
    sudo -u git -H ./bin/install

    5. Database

    To setup the MySQL/PostgreSQL database and dependencies please see doc/install/databases.md.

    6. 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://gitlab.com/gitlab-org/gitlab-ce.git -b 6-8-stable gitlab 

    # Go to gitlab dir 

    cd /home/git/gitlab

    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


    # If you installed Git from source, change the git bin_path to /usr/local/bin/git

    sudo -u git -H editor 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

    sudo chmod u+rwx,g+rx,o-rwx /home/git/gitlab-satellites

    # Make sure GitLab can write to the tmp/pids/ and tmp/sockets/ directories

    sudo chmod -R u+rwX tmp/pids/

    sudo chmod -R u+rwX tmp/sockets/

    # Make sure GitLab can write to the public/uploads/ directory

    sudo chmod -R u+rwX public/uploads

    # Copy the example Unicorn config

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

     # Enable cluster mode if you expect to have a high load instance # Ex. change amount of workers to 3 for 2GB RAM server

    sudo -u git -H editor config/unicorn.rb

    # Copy the example Rack attack config sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb

     # Configure Git global settings for git user, useful when editing via web

    # Edit user.email according to what is set in gitlab.yml

    sudo -u git -H git config --global user.name "GitLab"

    sudo -u git -H git config --global user.email "gitlab@localhost"

    sudo -u git -H git config --global core.autocrlf input

    Important Note: Make sure to edit both gitlab.yml and unicorn.rb 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. 
    # You only need to adapt the production settings (first part). 
    # If you followed the database guide then please do as follows:
     # Change 'root' to 'gitlab'
     # Change 'secure password' with the value you have given to $password 
    # You can keep the double quotes around the password 
    sudo -u git -H editor config/database.yml 
    # Make config/database.yml readable to git only 
    sudo -u git -H chmod o-rwx config/database.yml

    Install Gems

    cd /home/git/gitlab 
    sudo gem install charlock_holmes --version '' 
    # For MySQL (note, the option says "without ... postgres") 
    sudo -u git -H bundle install --deployment --without development test postgres aws 
    # Or for PostgreSQL (note, the option says "without ... mysql")
     sudo -u git -H bundle install --deployment --without development test mysql aws


    Initialize Database and Activate Advanced Features

    sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production 
    # Type 'yes' to create the database. 
    # When done you see 'Administrator account created:'

    Install Init Script


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

    sudo cp lib/support/init.d/gitlab /etc/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

    Start Your GitLab Instance

    sudo service gitlab start

    # or

    sudo /etc/init.d/gitlab restart

    Double-check Application Status

    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

    7. Nginx

    Note: Nginx is the officially supported web server for GitLab. If you cannot or do not want to use Nginx as your web server, have a look at the GitLab recipes.


    sudo apt-get install -y nginx

    Site Configuration

    Download an example site config:

    sudo cp lib/support/nginx/gitlab /etc/nginx/sites-available/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_FQDN to the fully-qualified

    # domain name of your host serving GitLab.

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


    sudo service nginx restart

    Important Note: Please go over to your profile page and immediately change the password, so nobody can access your GitLab by using this login information later on.

    Advanced Setup Tips

    Custom Redis Connection

    If you'd like Resque to connect to a Redis server on a non-standard port or on a different host, you can configure its connection string via the config/resque.yml file.

    # example production: redis://redis.example.tld:6379

    Custom SSH Connection

    If you are running SSH on a non-standard port, you must change the gitlab user's SSH config.

    # Add to /home/git/.ssh/config

    host localhost                  # Give your setup a name (here: override localhost)

    user git                              # Your remote git user

    port 2222                          # Your port number

    hostname;     # Your server name or IP

    You also need to change the corresponding options (e.g. ssh_user, ssh_host, admin_uri) in the config\gitlab.yml file.

    LDAP authentication

    You can configure LDAP authentication in config/gitlab.yml. Please restart GitLab after editing this file.

    Using Custom Omniauth Providers

    GitLab uses Omniauth for authentication and already ships with a few providers preinstalled (e.g. LDAP, GitHub, Twitter). But sometimes that is not enough and you need to integrate with other authentication solutions. For these cases you can use the Omniauth provider.


    These steps are fairly general and you will need to figure out the exact details from the Omniauth provider's documentation.

    • Stop GitLab sudo service gitlab stop
    • Add provider specific configuration options to your config/gitlab.yml (you can use the auth providers section of the example config as a reference)
    • Add the gem to your Gemfile gem "omniauth-your-auth-provider"
    • If you're using MySQL, install the new Omniauth provider gem by running the following command: sudo -u git -H bundle install --without development test postgres --path vendor/bundle --no-deployment
    • If you're using PostgreSQL, install the new Omniauth provider gem by running the following command: sudo -u git -H bundle install --without development test mysql --path vendor/bundle --no-deployment ( These are the same commands you used in the Install Gems section with --path vendor/bundle --no-deployment instead of --deployment).
    • Start GitLab sudo service gitlab start


    If you have successfully set up a provider that is not shipped with GitLab itself, please let us know. You can help others by reporting successful configurations and probably share a few insights or provide warnings for common errors or pitfalls by sharing your experience in the public Wiki. While we can't officially support every possible auth mechanism out there, we'd like to at least help those with special needs.
