Setup Database

GitLab supports the following databases:

• MySQL (preferred)
• PostgreSQL

MySQL

# Install the database packages
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

# Login to MySQL
$ mysql -u root -p

# Create a user for GitLab. (change $password to a real password)
mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';

# Create the GitLab production database
mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;

# Grant the GitLab user necessary permissopns on the table.
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';

# Quit the database session
mysql> \q

# Try connecting to the new database with the new user
sudo -u git -H mysql -u gitlab -p -D gitlabhq_production

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. (change $password to a real password)
template1=# CREATE USER gitlab WITH PASSWORD '$password';

# Create the GitLab production database & grant all privileges on database
template1=# CREATE DATABASE gitlabhq_production OWNER gitlab;

# Quit the database session
template1=# \q

# Try connecting to the new database with the new user
sudo -u git -H psql -d gitlabhq_production
