It's useful to make a backup just in case things go south: (With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version)
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
sudo service gitlab stop
cd /home/git/gitlab
sudo -u git -H git pull origin 6-2-stable
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.7.9
cd /home/git/gitlab
# MySQL
sudo -u git -H bundle install --without development test postgres --deployment
#PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
sudo -u git -H bundle exec rake assets:clean RAILS_ENV=production
sudo -u git -H bundle exec rake assets:precompile RAILS_ENV=production
sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
sudo service gitlab start
sudo service nginx restart
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
