# Overview

The GitLab installation consists of setting up th following components:

1. Packages / Dependencies
2. Ruby
3. System Users
4. Gitolite
5. Database
6. GitLab
7. Nginx


# 1. Packages / Dependencies

*Keep in mind that `sudo` is not installed on Debian by default. You should install it as root:*

    apt-get update && apt-get upgrade && apt-get install sudo

Make sure your system is up-to-date:

    sudo apt-get update
    sudo apt-get upgrade

Install the required packages:

    sudo apt-get install -y wget curl build-essential checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev zlib1g-dev libicu-dev redis-server openssh-server git-core libyaml-dev postfix

Make sure you have the right version of Python installed.

    # Install Python
    sudo apt-get install python

    # Make sure that Python is 2.x (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

    wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p327.tar.gz
    tar xfvz ruby-1.9.3-p327.tar.gz
    cd ruby-1.9.3-p327
    ./configure
    make
    sudo make install


# 3. System Users

Create a user for Git and Gitolite:

    sudo adduser \
      --system \
      --shell /bin/sh \
      --gecos 'Git Version Control' \
      --group \
      --disabled-password \
      --home /home/git \
      git

Create a user for GitLab:

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

    # Add it to the git group
    sudo addmod -a -G git gitlab

    # Generate the SSH key
    sudo -u gitlab -H ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa


# 4. Gitolite

Clone GitLab's fork of the Gitolite source code:

    sudo -u git -H git clone -b gl-v304 https://github.com/gitlabhq/gitolite.git /home/git/gitolite

Setup Gitolite with GitLab as its admin:

**Important Note**
GitLab assumes *full and unshared* control over this Gitolite installation.

    # Add Gitolite scripts to $PATH
    cd /home/git
    sudo -u git -H mkdir bin
    sudo -u git -H sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" >> /home/git/.profile'
    sudo -u git -H sh -c 'gitolite/install -ln /home/git/bin'

    # Copy the gitlab user's (public) SSH key ...
    sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
    sudo chmod 0444 /home/git/gitlab.pub

    # ... and use it as the Gitolite admin key for setup
    sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gitolite setup -pk /home/git/gitlab.pub"

Fix the directory permissions for the repository:

    # Make sure the repositories dir is owned by git and it stays that way
    sudo chmod -R ug+rwXs /home/git/repositories/
    sudo chown -R git:git /home/git/repositories/

## Test if everything works so far

    # Clone the admin repo so SSH adds localhost to known_hosts ...
    # ... and to be sure your users have access to Gitolite
    sudo -u gitlab -H git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin

    # If it succeeded without errors you can remove the cloned repo
    sudo rm -rf /tmp/gitolite-admin

**Impornant Note**
If you can't clone the `gitolite-admin` repository: **DO NOT PROCEED WITH INSTALLATION**
Check the [Trouble Shooting Guide](https://github.com/gitlabhq/gitlab-public-wiki/wiki/Trouble-Shooting-Guide)
and make sure you have followed all of the above steps carefully.


# 5. Database

See doc/install/databases.md


# 6. GitLab

    We'll install GitLab into the gitlab user's home directory
    cd /home/gitlab

## Clone the Source

    # Clone the latest stable release
    sudo -u gitlab -H git clone -b stable https://github.com/gitlabhq/gitlabhq.git gitlab

**Note***
You can change `stable` to `master` if you want the *bleeding edge* version, but
do so with caution!

## Configure it

    cd /home/gitlab/gitlab

    # Copy the example GitLab config
    sudo -u gitlab -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 gitlab -H vim config/gitlab.yml

    # Copy the example Unicorn config
    sudo -u gitlab -H cp config/unicorn.rb.example config/unicorn.rb

**Important Note**
Make sure to edit both files to match your setup.

## Install Gems

    cd /home/gitlab/gitlab

    sudo gem install charlock_holmes --version '0.6.9'
    sudo gem install bundler
    sudo -u gitlab -H bundle install --deployment --without development test 

## Configure Git

GitLab needs to be able to commit and push changes to Gitolite. In order to do
that Git requires a username and email. (Please use the `email.from` address
for the email)

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

## Setup GitLab hooks

    sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
    sudo chown git:git /home/git/.gitolite/hooks/common/post-receive

## Initialise Database and Activate Advanced Features

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


## Check Application Status

Check if GitLab  and its environment is configured correctly:

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

```

If you are all green - congratulations! You run a GitLab now.
But there are still a few steps to go.


## Install Init Script

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

    sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/init.d/gitlab -P /etc/init.d/
    sudo chmod +x /etc/init.d/gitlab

Make GitLab start on boot:

    sudo update-rc.d gitlab defaults 21


Start your GitLab instance:

    sudo service gitlab start


# 7. Nginx

## Installation
    sudo apt-get install nginx

## Site Configuration

Download an example site config:

    sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab -P /etc/nginx/sites-available/
    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-enabled/gitlab

## Restart

    sudo /etc/init.d/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 connections

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.example.tld:6379
