From 8.15 to 8.16
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 at the top left corner of GitLab (below the menu bar).
If the highest number stable branch is unclear please check the GitLab Blog for installation guide links by version.
1. Stop server
sudo service gitlab stop
2. Backup
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
3. Update Ruby
We will continue supporting Ruby < 2.3 for the time being but we recommend you upgrade to Ruby 2.3 if you're running a source installation, as this is the same version that ships with our Omnibus package.
You can check which version you are running with ruby -v.
Download and compile Ruby:
mkdir /tmp/ruby && cd /tmp/ruby
curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
echo '1014ee699071aa2ddd501907d18cbe15399c997d ruby-2.3.3.tar.gz' | shasum -c - && tar xzf ruby-2.3.3.tar.gz
cd ruby-2.3.3
./configure --disable-install-rdoc
make
sudo make install
Install Bundler:
sudo gem install bundler --no-ri --no-rdoc
4. Get latest code
cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
For GitLab Community Edition:
cd /home/git/gitlab
sudo -u git -H git checkout 8-16-stable
OR
For GitLab Enterprise Edition:
cd /home/git/gitlab
sudo -u git -H git checkout 8-16-stable-ee
5. Install libs, migrations, etc.
cd /home/git/gitlab
# MySQL installations (note: the line below states '--without postgres')
sudo -u git -H bundle install --without postgres development test --deployment
# PostgreSQL installations (note: the line below states '--without mysql')
sudo -u git -H bundle install --without mysql development test --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 assets:clean assets:precompile cache:clear RAILS_ENV=production
MySQL installations: Run through the MySQL strings limits and Tables and data conversion to utf8mb4 tasks.
6. Update gitlab-workhorse
Install and compile gitlab-workhorse. This requires Go 1.5 which should already be on your system from GitLab 8.1.
cd /home/git/gitlab
sudo -u git -H bundle exec rake "gitlab:workhorse:install[/home/git/gitlab-workhorse]" RAILS_ENV=production
7. Update gitlab-shell
cd /home/git/gitlab-shell
sudo -u git -H git fetch --all --tags
sudo -u git -H git checkout v4.1.1
8. Update configuration files
New configuration options for gitlab.yml
There are new configuration options available for gitlab.yml. View them with the command below and apply them manually to your current gitlab.yml:
cd /home/git/gitlab
git diff origin/8-15-stable:config/gitlab.yml.example origin/8-16-stable:config/gitlab.yml.example
Git configuration
Configure Git to generate packfile bitmaps (introduced in Git 2.0) on
the GitLab server during git gc.
cd /home/git/gitlab
sudo -u git -H git config --global repack.writeBitmaps true
Nginx configuration
Ensure you're still up-to-date with the latest NGINX configuration changes:
cd /home/git/gitlab
# For HTTPS configurations
git diff origin/8-15-stable:lib/support/nginx/gitlab-ssl origin/8-16-stable:lib/support/nginx/gitlab-ssl
# For HTTP configurations
git diff origin/8-15-stable:lib/support/nginx/gitlab origin/8-16-stable:lib/support/nginx/gitlab
If you are using Apache instead of NGINX please see the updated Apache templates. Also note that because Apache does not support upstreams behind Unix sockets you will need to let gitlab-workhorse listen on a TCP port. You can do this via /etc/default/gitlab.
SMTP configuration
If you're installing from source and use SMTP to deliver mail, you will need to add the following line to config/initializers/smtp_settings.rb:
ActionMailer::Base.delivery_method = :smtp
See smtp_settings.rb.sample as an example.
Init script
Ensure you're still up-to-date with the latest init script changes:
cd /home/git/gitlab
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
For Ubuntu 16.04.1 LTS:
sudo systemctl daemon-reload
9. Start application
sudo service gitlab start
sudo service nginx restart
10. 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:
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
If all items are green, then congratulations, the upgrade is complete!
Things went south? Revert to previous version (8.15)
1. Revert the code to the previous version
Follow the upgrade guide from 8.14 to 8.15, 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
If you have more than one backup *.tar file(s) please add BACKUP=timestamp_of_backup to the command above.
