# Overview
2012-03-12 13:47:57 +01:00
The GitLab installation consists of setting up the following components:
2012-12-05 20:34:11 +01:00
1. Packages / Dependencies
2012-10-24 19:59:48 +02:00
2. Ruby
2012-12-05 20:34:11 +01:00
3. System Users
2012-10-24 19:59:48 +02:00

2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
# 1. Packages / Dependencies
2012-03-12 13:47:57 +01:00
`sudo` is not installed on Debian by default. If you don't have it you'll need
to install it first.
# run as root
apt-get update && apt-get upgrade && apt-get install sudo
2012-12-05 20:34:11 +01:00
Make sure your system is up-to-date:
2012-03-12 13:47:57 +01:00
sudo apt-get update
sudo apt-get upgrade
**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
2012-12-05 20:34:11 +01:00
Install the required packages:
2012-12-12 22:36:20 +01:00
sudo apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev wget 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
2012-12-12 22:36:20 +01:00
# 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
2012-12-05 20:34:11 +01:00
# 2. Ruby
2012-03-12 13:47:57 +01:00
Download and compile it:
mkdir /tmp/ruby && cd /tmp/ruby
2012-12-05 20:34:11 +01:00
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
2012-03-12 13:47:57 +01:00
./configure
make
sudo make install
Install the Bundler Gem:
sudo gem install bundler
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
# 3. System Users
Create a user for Git and Gitolite:
2012-03-12 13:47:57 +01:00
sudo adduser \
--system \
--shell /bin/sh \
2012-12-05 20:34:11 +01:00
--gecos 'Git Version Control' \
2012-03-12 13:47:57 +01:00
--group \
--disabled-password \
--home /home/git \
git
2012-12-05 20:34:11 +01:00
Create a user for GitLab:
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
sudo adduser --disabled-login --gecos 'GitLab' gitlab
2012-12-05 20:34:11 +01:00
# Add it to the git group
2012-12-09 15:05:24 +01:00
sudo usermod -a -G git gitlab
2012-12-05 20:34:11 +01:00
# Generate the SSH key
2012-12-05 18:21:28 +01:00
sudo -u gitlab -H ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa
2012-03-12 13:47:57 +01:00
2012-10-24 19:59:48 +02:00
# 4. Gitolite
Clone GitLab's fork of the Gitolite source code:
cd /home/git
2012-12-17 14:11:33 +01:00
sudo -u git -H git clone -b gl-v320 https://github.com/gitlabhq/gitolite.git /home/git/gitolite
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
Setup Gitolite with GitLab as its admin:
**Important Note:**
2012-12-05 20:34:11 +01:00
GitLab assumes *full and unshared* control over this Gitolite installation.
2012-12-05 20:34:11 +01:00
# Add Gitolite scripts to $PATH
sudo -u git -H mkdir /home/git/bin
sudo -u git -H sh -c 'printf "%b\n%b\n" "PATH=\$PATH:/home/git/bin" "export PATH" >> /home/git/.profile'
2012-12-05 18:21:28 +01:00
sudo -u git -H sh -c 'gitolite/install -ln /home/git/bin'
2012-08-29 01:03:04 +02:00
2012-12-05 20:34:11 +01:00
# Copy the gitlab user's (public) SSH key ...
2012-03-12 13:47:57 +01:00
sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
sudo chmod 0444 /home/git/gitlab.pub
2012-03-12 13:47:57 +01:00
# ... and use it as the admin key for the Gitolite setup
2012-08-29 01:03:04 +02:00
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gitolite setup -pk /home/git/gitlab.pub"
Fix the directory permissions for the configuration directory:
# Make sure the Gitolite config dir is owned by git
sudo chmod 750 /home/git/.gitolite/
sudo chown -R git:git /home/git/.gitolite/
2012-12-12 22:36:20 +01:00
Fix the directory permissions for the repositories:
2012-12-05 20:34:11 +01:00
# Make sure the repositories dir is owned by git and it stays that way
2012-12-12 22:36:20 +01:00
sudo chmod -R ug+rwXs,o-rwx /home/git/repositories/
2012-03-12 13:47:57 +01:00
sudo chown -R git:git /home/git/repositories/
2012-12-22 23:35:52 +01:00
## Disable StrictHostKeyChecking for localhost and your domain
echo "Host localhost
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config
echo "Host YOUR_DOMAIN_NAME
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config
# If gitolite domain differs
echo "Host YOUR_GITOLITE_DOMAIN
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config
2012-12-05 20:34:11 +01:00
## 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
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
# If it succeeded without errors you can remove the cloned repo
sudo rm -rf /tmp/gitolite-admin
2012-03-12 13:47:57 +01:00
**Important 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)
2012-12-05 20:34:11 +01:00
and make sure you have followed all of the above steps carefully.
2012-03-12 13:47:57 +01:00
# 5. Database
2012-10-24 19:42:55 +02:00
See `doc/install/databases.md`
2012-10-24 19:42:55 +02:00
2012-10-24 19:59:48 +02:00
# 6. GitLab
2012-03-12 13:47:57 +01:00
# We'll install GitLab into home directory of the user "gitlab"
2012-03-12 13:47:57 +01:00
cd /home/gitlab
2012-12-05 20:34:11 +01:00
## Clone the Source
2012-10-24 19:59:48 +02:00
2012-12-23 12:57:40 +01:00
# Clone GitLab repository
sudo -u gitlab -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab
2012-12-23 12:58:41 +01:00
# Go to gitlab dir
cd /home/gitlab/gitlab
2012-12-23 12:57:40 +01:00
# Checkout to stable release
sudo -u gitlab -H git checkout 4-0-stable
**Note:**
2012-12-23 12:57:40 +01:00
You can change `4-0-stable` to `master` if you want the *bleeding edge* version, but
2012-12-05 20:34:11 +01:00
do so with caution!
2012-12-05 20:34:11 +01:00
## Configure it
2012-10-24 19:59:48 +02:00
2012-12-05 20:34:11 +01:00
cd /home/gitlab/gitlab
2012-12-05 20:34:11 +01:00
# Copy the example GitLab config
2012-12-05 18:21:28 +01:00
sudo -u gitlab -H cp config/gitlab.yml.example config/gitlab.yml
2012-03-12 13:47:57 +01:00
2012-12-07 17:28:05 +01:00
# 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
2012-12-12 22:36:20 +01:00
# Make sure GitLab can write to the log/ and tmp/ directories
sudo chown -R gitlab log/
sudo chown -R gitlab tmp/
sudo chmod -R u+rwX log/
sudo chmod -R u+rwX tmp/
2012-12-05 20:34:11 +01:00
# Copy the example Unicorn config
2012-12-05 18:21:28 +01:00
sudo -u gitlab -H cp config/unicorn.rb.example config/unicorn.rb
2012-10-10 01:41:33 +02:00
**Important Note:**
2012-12-05 20:34:11 +01:00
Make sure to edit both files to match your setup.
## Configure GitLab DB settings
# Mysql
sudo -u gitlab cp config/database.yml.mysql config/database.yml
# PostgreSQL
sudo -u gitlab cp config/database.yml.postgresql config/database.yml
Make sure to update username/password in config/database.yml.
2012-12-05 20:34:11 +01:00
## Install Gems
2012-10-24 19:59:48 +02:00
cd /home/gitlab/gitlab
sudo gem install charlock_holmes --version '0.6.9'
# For mysql db
sudo -u gitlab -H bundle install --deployment --without development test postgres
# Or For postgres db
sudo -u gitlab -H bundle install --deployment --without development test mysql
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
## Configure Git
2012-12-05 20:34:11 +01:00
GitLab needs to be able to commit and push changes to Gitolite. In order to do
that Git requires a username and email. (We recommend using the same address
used for the `email.from` setting in `config/gitlab.yml`)
2012-12-05 20:34:11 +01:00
sudo -u gitlab -H git config --global user.name "GitLab"
sudo -u gitlab -H git config --global user.email "gitlab@localhost"
2012-12-12 22:36:20 +01:00
## Setup GitLab Hooks
2012-12-05 20:34:11 +01:00
sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
sudo chown git:git /home/git/.gitolite/hooks/common/post-receive
2012-12-05 20:34:11 +01:00
## Initialise Database and Activate Advanced Features
2012-10-24 19:50:34 +02:00
2012-12-05 20:34:11 +01:00
sudo -u gitlab -H bundle exec rake gitlab:app:setup RAILS_ENV=production
## 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
2012-12-05 20:34:11 +01:00
## 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:
2012-12-12 22:36:20 +01:00
sudo -u gitlab -H bundle exec rake gitlab:check RAILS_ENV=production
2012-03-12 13:47:57 +01:00
If all items are green, then congratulations on successfully installing GitLab!
However there are still a few steps left.
2012-03-12 13:47:57 +01:00
## Start Your GitLab Instance
2012-03-12 13:47:57 +01:00
2012-10-24 19:50:34 +02:00
sudo service gitlab start
2012-12-12 22:36:20 +01:00
# or
sudo /etc/init.d/gitlab restart
2012-03-12 13:47:57 +01:00
2012-10-24 19:50:34 +02:00
# 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" section.
2012-12-05 20:34:11 +01:00
## Installation
sudo apt-get install nginx
2012-12-05 20:34:11 +01:00
## Site Configuration
Download an example site config:
2012-09-04 18:44:17 +02:00
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
2012-03-12 13:47:57 +01:00
2012-12-05 20:34:11 +01:00
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
2012-12-05 20:34:11 +01:00
# of your host serving GitLab
sudo vim /etc/nginx/sites-enabled/gitlab
2012-03-13 19:19:03 +01:00
2012-12-05 20:34:11 +01:00
## Restart
sudo /etc/init.d/nginx restart
2012-03-13 19:19:03 +01:00
2012-12-05 20:34:11 +01:00
# Done!
2012-12-05 20:34:11 +01:00
Visit YOUR_SERVER for your first GitLab login.
The setup has created an admin account for you. You can use it to log in:
2012-03-12 13:51:21 +01:00
admin@local.host
5iveL!fe
**Important Note:**
2012-12-05 20:34:11 +01:00
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!**

## Custom Redis Connection
If you'd like Resque to connect to a Redis server on a non-standard port or on
2012-12-05 20:34:11 +01:00
a different host, you can configure its connection string via the
`config/resque.yml` file.
2012-12-05 20:34:11 +01:00
# example
production: redis.example.tld:6379
