# Select Version to Install
Make sure you view this installation guide from the branch (version) of GitLab CI you would like to install. In most cases
this should be the highest numbered stable branch (example shown below).
If this is unclear check the [GitLab Blog](http://blog.gitlab.org/) for installation guide links by version.
## GitLab CI 7.12 requires GitLab 7.12 or newer
other [requirements](requirements.md)
# Setup:
## 1. Packages / Dependencies
`sudo` is not installed on Debian by default. Make sure your system is
up-to-date and install it.
sudo apt-get update
sudo apt-get upgrade
**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
sudo apt-get install vim
sudo update-alternatives --set editor /usr/bin/vim.basic
Install the required packages:
sudo apt-get install wget curl gcc checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev libmysql++-dev make build-essential zlib1g-dev openssh-server git-core libyaml-dev postfix libpq-dev libicu-dev openssl nodejs
sudo apt-get install redis-server
# 2. Ruby
Download Ruby and compile it:
mkdir /tmp/ruby && cd /tmp/ruby
curl --progress http://cache.ruby-lang.org/pub/ruby/ruby-2.1.6.tar.bz2 | tar xj
cd ruby-2.1.6/
./configure --disable-install-rdoc
make
sudo make install
Install the Bundler Gem:
sudo gem install bundler --no-ri --no-rdoc
## 3. GitLab CI user:
sudo adduser --disabled-login --gecos 'GitLab CI' gitlab_ci
## 4. Prepare the database
We recommend PostgreSQL but you can also use MySQL
### MySQL
# Install the database packages
sudo apt-get install mysql-server mysql-client libmysqlclient-dev
# Login to MySQL
$ mysql -u root -p
# Create the GitLab CI database
mysql> CREATE DATABASE IF NOT EXISTS `gitlab_ci_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
# Create the MySQL User change $password to a real password
mysql> CREATE USER 'gitlab_ci'@'localhost' IDENTIFIED BY '$password';
# Grant proper permissions to the MySQL User
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `gitlab_ci_production`.* TO 'gitlab_ci'@'localhost';
# Logout MYSQL
mysql> exit;
### PostgreSQL
# Install the database packages
sudo apt-get install -y postgresql-9.1 libpq-dev
# Login to PostgreSQL
sudo -u postgres psql -d template1
# Create a user for GitLab CI. We do not specify a password because we are using peer authentication.
template1=# CREATE USER gitlab_ci;
# Create the GitLab CI production database & grant all privileges on database
template1=# CREATE DATABASE gitlab_ci_production OWNER gitlab_ci;
# Quit the database session
template1=# \q
# Try connecting to the new database with the new user
sudo -u gitlab_ci -H psql -d gitlab_ci_production
## 5. Get code
cd /home/gitlab_ci/
sudo -u gitlab_ci -H git clone https://gitlab.com/gitlab-org/gitlab-ci.git
cd gitlab-ci
sudo -u gitlab_ci -H git checkout 7-12-stable
## 6. Setup application
# Edit application settings
# Production
sudo -u gitlab_ci -H cp config/application.yml.example config/application.yml
sudo -u gitlab_ci -H editor config/application.yml
# Development
#sudo -u gitlab_ci -H cp config/application.yml.example.development config/application.yml
# Copy the example secrets file
sudo -u gitlab_ci -H cp config/secrets.yml.example config/secrets.yml
sudo -u gitlab_ci -H chmod 0600 config/secrets.yml
# Edit web server settings
sudo -u gitlab_ci -H cp config/unicorn.rb.example config/unicorn.rb
sudo -u gitlab_ci -H editor config/unicorn.rb
# Create socket and pid directories
sudo -u gitlab_ci -H mkdir -p tmp/sockets/
sudo chmod -R u+rwX tmp/sockets/
sudo -u gitlab_ci -H mkdir -p tmp/pids/
sudo chmod -R u+rwX tmp/pids/
# Change the permissions of the directory where build traces are stored
sudo chmod -R u+rwX builds/
### Install gems
# For MySQL (note, the option says "without ... postgres")
sudo -u gitlab_ci -H bundle install --without development test postgres --deployment
# Or for PostgreSQL (note, the option says "without ... mysql")
sudo -u gitlab_ci -H bundle install --without development test mysql --deployment
### Setup db
# mysql
sudo -u gitlab_ci -H cp config/database.yml.mysql config/database.yml
# postgres
sudo -u gitlab_ci -H cp config/database.yml.postgresql config/database.yml
# Edit user/password (not necessary with default Postgres setup)
sudo -u gitlab_ci -H editor config/database.yml
# Setup tables
sudo -u gitlab_ci -H bundle exec rake setup RAILS_ENV=production
# Setup schedules
sudo -u gitlab_ci -H bundle exec whenever -w RAILS_ENV=production
### Secure secrets.yml
The `secrets.yml` file stores encryption keys for sessions and secure variables.
Backup `secrets.yml` someplace safe, but don't store it in the same place as your database backups.
Otherwise your secrets are exposed if one of your backups is compromised.
## 8. Install Init Script
Copy the init script (will be /etc/init.d/gitlab_ci):
sudo cp /home/gitlab_ci/gitlab-ci/lib/support/init.d/gitlab_ci /etc/init.d/gitlab_ci
Make GitLab CI start on boot:
sudo update-rc.d gitlab_ci defaults 21
Start your GitLab CI instance:
sudo service gitlab_ci start
# or
sudo /etc/init.d/gitlab_ci start
# 8. Nginx
## Installation
sudo apt-get install nginx
## Site Configuration
Download an example site config:
sudo cp /home/gitlab_ci/gitlab-ci/lib/support/nginx/gitlab_ci /etc/nginx/sites-available/gitlab_ci
sudo ln -s /etc/nginx/sites-available/gitlab_ci /etc/nginx/sites-enabled/gitlab_ci
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 CI
sudo editor /etc/nginx/sites-enabled/gitlab_ci
## Check your configuration
sudo nginx -t
## Start nginx
sudo /etc/init.d/nginx start
# 9. GitLab OAuth2 application
Go to the admin area of GitLab, to the `Application` section. Create an application for the GitLab CI
For callback URL use: `http://ci.example.com/user_sessions/callback` if you use http, or `https://ci.example.com/user_sessions/callback` if you use https.
When `app_id` and `app_secret` are generated add them to the GitLab CI config:
```
production:
gitlab_server:
url: 'http://gitlab.example.com'
app_id: XXXXXX
app_secret: XXXXXX
```
# 10. Runners
Now you need Runners to process your builds.
Checkout the [Gitlab Runner section](https://about.gitlab.com/gitlab-ci/#gitlab-runner) to install it
# Done!
Visit YOUR_SERVER for your first GitLab CI login.
You will be asked to authorize with your GitLab credentials.
**Enjoy!**
## Advanced settings
### SMTP email settings
If you want to use SMTP do next:
# Copy config file
sudo -u gitlab_ci -H cp config/initializers/smtp_settings.rb.sample config/initializers/smtp_settings.rb
# Edit it with your settings
sudo -u gitlab_ci -H editor config/initializers/smtp_settings.rb
Restart application
### 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
