# Select Version to Install Make sure you view [this installation guide](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/installation.md) from the branch (version) of GitLab you would like to install. In most cases this should be the highest numbered stable branch (example shown below). ![capture](http://i.imgur.com/d2AlIVj.png) If the highest number stable branch is unclear please check the [GitLab Blog](https://www.gitlab.com/blog/) for installation guide links by version. # 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](https://twitter.com/robinvdvleuten/status/424163226532986880). This installation guide was created for and tested on **Debian/Ubuntu** operating systems. Please read [doc/install/requirements.md](./requirements.md) for hardware and operating system requirements. If you want to install on RHEL/CentOS we recommend using the [Omnibus packages](https://www.gitlab.com/downloads/). This is the official installation guide to set up a production server. To set up a **development installation** or for many other installation options please see [the installation section of the readme](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/README.md#installation). 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. If you find a bug/error in this guide please **submit a merge request** following the [contributing guide](../../CONTRIBUTING.md). - - - # Overview The GitLab installation consists of setting up the following components: 1. Packages / Dependencies 2. Ruby 3. System 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 **Note:** During this installation some files will need to be edited manually. If you are familiar with vim set it as default editor with the commands below. If you are not familiar with vim please skip this and keep using the default editor. # 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 Git installed # Install Git sudo apt-get install -y git-core # Make sure Git is version 1.7.10 or higher, for example 1.7.12 or 1.8.4 git --version Is the system packaged Git too old? Remove it and compile from source. # Remove packaged Git sudo apt-get remove git-core # Install dependencies sudo apt-get install -y libcurl4-openssl-dev libexpat1-dev gettext libz-dev libssl-dev build-essential # Download and compile from source cd /tmp curl --progress https://git-core.googlecode.com/files/git-1.8.5.2.tar.gz | tar xz cd git-1.8.5.2/ make prefix=/usr/local all # Install into /usr/local/bin sudo make prefix=/usr/local install # When editing config/gitlab.yml (Step 6), change the git bin_path to /usr/local/bin/git **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](http://rvm.io/), [rbenv](https://github.com/sstephenson/rbenv) or [chruby](https://github.com/postmodern/chruby) with GitLab in production frequently leads to hard to diagnose problems. For example, GitLab Shell is called from OpenSSH and having a version manager can prevent pushing and pulling over SSH. Version managers are not supported and we stronly advise everyone to follow the instructions below to use a system ruby. 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-p481.tar.gz | tar xz cd ruby-2.0.0-p481 ./configure --disable-install-rdoc make sudo make install Install the Bundler Gem: sudo gem install bundler --no-ri --no-rdoc # 3. System Users Create a `git` user for Gitlab: sudo adduser --disabled-login --gecos 'GitLab' git # 4. Database We recommend using a PostgreSQL database. For MySQL check [MySQL setup guide](database_mysql.md). NOTE: because we need to make use of extensions you need at least pgsql 9.1. # Install the database packages sudo apt-get install -y postgresql-9.1 postgresql-client libpq-dev # Login to PostgreSQL sudo -u postgres psql -d template1 # Create a user for GitLab. template1=# CREATE USER git CREATEDB; # Create the GitLab production database & grant all privileges on database template1=# CREATE DATABASE gitlabhq_production OWNER git; # Quit the database session template1=# \q # Try connecting to the new database with the new user sudo -u git -H psql -d gitlabhq_production # 5. 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 6-9-stable gitlab # Go to gitlab dir cd /home/git/gitlab **Note:** You can change `6-9-stable` to `master` if you want the *bleeding edge* version, but never install master on a production server! ## 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 "example@example.com" 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 # PostgreSQL only: sudo -u git cp config/database.yml.postgresql config/database.yml # MySQL only: sudo -u git cp config/database.yml.mysql config/database.yml # MySQL and remote PostgreSQL only: # 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 '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 # PostgreSQL and MySQL: # Make config/database.yml readable to git only sudo -u git -H chmod o-rwx config/database.yml ## Install Gems **Note:** As of bundler 1.5.2, you can invoke `bundle install -jN` (where `N` the number of your processor cores) and enjoy the parallel gems installation with measurable difference in completion time (~60% faster). Check the number of your cores with `nproc`. For more information check this [post](http://robots.thoughtbot.com/parallel-gem-installing-using-bundler). First make sure you have bundler >= 1.5.2 (run `bundle -v`) as it addresses some [issues](https://devcenter.heroku.com/changelog-items/411) that were [fixed](https://github.com/bundler/bundler/pull/2817) in 1.5.2. cd /home/git/gitlab # For PostgreSQL (note, the option says "without ... mysql") sudo -u git -H bundle install --deployment --without development test mysql aws # Or if you use MySQL (note, the option says "without ... postgres") sudo -u git -H bundle install --deployment --without development test postgres aws ## Install GitLab shell GitLab Shell is an ssh access and repository management software developed specially for GitLab. # Go to the Gitlab installation folder: cd /home/git/gitlab # Run the installation task for gitlab-shell (replace `REDIS_URL` if needed): sudo -u git -H bundle exec rake gitlab:shell:install[v1.9.4] REDIS_URL=redis://localhost:6379 RAILS_ENV=production # By default, the gitlab-shell config is generated from your main gitlab config. You can review (and modify) it as follows: sudo -u git -H editor /home/git/gitlab-shell/config.yml ## Initialize Database and Activate Advanced Features sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production # Type 'yes' to create the database tables. # 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 And if you are installing with a non-default folder or user copy and edit the defaults file: sudo cp lib/support/init.d/gitlab.default.example /etc/default/gitlab If you installed gitlab in another directory or as a user other than the default you should change these settings in /etc/default/gitlab. Do not edit /etc/init.d/gitlab as it will be changed on upgrade. Make GitLab start on boot: sudo update-rc.d gitlab defaults 21 ## Set up logrotate sudo cp lib/support/logrotate/gitlab /etc/logrotate.d/gitlab ## 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 ## Compile assets sudo -u git -H bundle exec rake assets:precompile RAILS_ENV=production ## Start Your GitLab Instance sudo service gitlab start # or sudo /etc/init.d/gitlab restart # 6. 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](https://gitlab.com/gitlab-org/gitlab-recipes/). ## Installation 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 ## Restart sudo service nginx restart # Done! ## 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 If all items are green, then congratulations on successfully installing GitLab! ## Initial Login Visit YOUR_SERVER in your web browser for your first GitLab login. The setup has created an admin account for you. You can use it to log in: root 5iveL!fe **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. **Enjoy!** - - - # Advanced Setup Tips ## Additional markup styles Apart from the always supported markdown style there are other rich text files that GitLab can display. But you might have to install a dependency to do so. Please see the [github-markup gem readme](https://github.com/gitlabhq/markup#markups) for more information. For example, reStructuredText markup language support requires python-docutils: sudo apt-get install -y python-docutils ## 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 If you want to connect the Redis server via socket, then use the "unix:" URL scheme and the path to the Redis socket file in the `config/resque.yml` file. # example production: unix:/path/to/redis/socket ## 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 127.0.0.1; # 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](http://www.omniauth.org/) 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. ### Steps 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](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/gitlab.yml.example) as a reference) * Add the gem to your [Gemfile](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/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](#install-gems) with `--path vendor/bundle --no-deployment` instead of `--deployment`. * Start GitLab `sudo service gitlab start` ### Examples 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](https://github.com/gitlabhq/gitlab-public-wiki/wiki/Custom-omniauth-provider-configurations). While we can't officially support every possible auth mechanism out there, we'd like to at least help those with special needs.
