GitLab Documentation

From 6.2 to 6.3

Make sure you view this upgrade guide from the master branch for the most up to date instructions.

Requires version: 6.1 or 6.2.

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

cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout 6-3-stable
# For GitLab Enterprise Edition: sudo -u git -H git checkout 6-3-stable-ee

3. Update gitlab-shell (and its config)

cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.7.9 # Addresses multiple critical security vulnerabilities

The gitlab-shell config changed recently, so check for config file changes and make /home/git/gitlab-shell/config.yml the same as https://github.com/gitlabhq/gitlab-shell/blob/master/config.yml.example

4. Install libs, migrations, etc.

cd /home/git/gitlab

# The Modernizr gem was yanked from RubyGems. It is required for GitLab >= 2.8.0
# Edit `Gemfile` and change `gem "modernizr", "2.5.3"` to
# `gem "modernizr-rails", "2.7.1"``
sudo -u git -H vim Gemfile

# MySQL

# Run a bundle install without deployment to generate the new Gemfile
sudo -u git -H bundle install --without development test postgres --no-deployment

# Install libs (with deployment this time)
sudo -u git -H bundle install --without development test postgres --deployment

# PostgreSQL

# Run a bundle install without deployment to generate the new Gemfile
sudo -u git -H bundle install --without development test mysql --no-deployment

# Install libs (with deployment this time)
sudo -u git -H bundle install --without development test mysql --deployment

# Both MySQL and PostgreSQL
# 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 assets:clean assets:precompile cache:clear RAILS_ENV=production

5. Update config files

TIP: to see what changed in gitlab.yml.example in this release use next command:

git diff 6-2-stable:config/gitlab.yml.example 6-3-stable:config/gitlab.yml.example
# Copy rack attack middleware config
cd /home/git/gitlab
sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb

6. Update Init script

sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab

7. Start application

sudo service gitlab start
sudo service nginx restart

8. Check application status

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

If all items are green, then congratulations upgrade complete!

Things went south? Revert to previous version (6.2)

1. Revert the code to the previous version

Follow the upgrade guide from 6.1 to 6.2, except for the database migration (the backup is already migrated to the previous version).

2. Restore from the backup:

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
