Select Version to Install

Make sure you view this update guide from the tag (version) of GitLab you would like to install. In most cases this should be the highest numbered production tag (without rc in it). You can select the tag in the version dropdown in the top left corner of GitLab (below the menu bar).

0. Backup 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 1\. Stop server sudo service gitlab stop 2\. Get latest code for the stable branch In the commands below, replace LATEST\_TAG with the latest GitLab tag you want to update to, for example v8.0.3. Use git tag -l 'v\*.\[0-9\]' --sort='v:refname' to see a list of all tags. Make sure to update patch versions only (check your current version with cat VERSION). cd /home/git/gitlab sudo -u git -H git fetch --all sudo -u git -H git checkout -- Gemfile.lock db/schema.rb sudo -u git -H git checkout LATEST\_TAG -b LATEST\_TAG 3\. Install libs, migrations, etc. cd /home/git/gitlab \# PostgreSQL sudo -u git -H bundle install --without development test mysql --deployment \# MySQL sudo -u git -H bundle install --without development test postgres --deployment \# Optional: clean up old gems sudo -u git -H bundle clean \# Run database migrations sudo -u git -H bundle exec rake db:migrate RAILS\_ENV=production \# Clean up assets and cache sudo -u git -H bundle exec rake gitlab:assets:clean gitlab:assets:compile cache:clear RAILS\_ENV=production 4\. Update gitlab-workhorse to the corresponding version cd /home/git/gitlab sudo -u git -H bundle exec rake "gitlab:workhorse:install\[/home/git/gitlab-workhorse\]" RAILS\_ENV=production 5\. Update gitlab-shell to the corresponding version cd /home/git/gitlab-shell sudo -u git -H git fetch --all --tags sudo -u git -H git checkout v\`cat /home/git/gitlab/GITLAB\_SHELL\_VERSION\` -b v\`cat /home/git/gitlab/GITLAB\_SHELL\_VERSION\` 6\. Start application sudo service gitlab start sudo service nginx restart 7\. Check application status Check if GitLab and its environment are configured correctly: cd /home/git/gitlab 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 If all items are green, then congratulations upgrade complete!
