# Overview

The GitLab installation consists of setting up the following components:

1. Packages / Dependencies
2. Ruby
3. System Users
4. GitLab shell
5. Database
6. GitLab
7. 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
    apt-get upgrade
    apt-get install sudo

**Note:**
Vim is an editor that is used here whenever there are files that need to be
edited by hand. But, you can use any editor you like instead.

    # Install vim
    sudo apt-get install -y vim

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


# 2. 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


# 3. System Users

Create a `git` user for Gitlab:

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


# 4. 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


# 5. Database

To setup the MySQL/PostgreSQL database and dependencies please see [`doc/install/databases.md`](./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://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
    # or
    sudo /etc/init.d/gitlab restart


# 7. 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`](./installation.md#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!

Visit YOUR_SERVER for your first GitLab login.
The setup has created an admin account for you. You can use it to log in:

    admin@local.host
    5iveL!fe

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

**Enjoy!**

# 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 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.
