GitLab 中文文档

From 8.3 to 8.4

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. Get latest code

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:

sudo -u git -H git checkout 8-4-stable

OR

For GitLab Enterprise Edition:

sudo -u git -H git checkout 8-4-stable-ee

4. Update gitlab-shell

cd /home/git/gitlab-shell
sudo -u git -H git fetch --all
sudo -u git -H git checkout v2.6.10

5. 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-workhorse
sudo -u git -H git fetch --all
sudo -u git -H git checkout 0.6.2
sudo -u git -H make

6. 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

# 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

7. 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:

git diff origin/8-3-stable:config/gitlab.yml.example origin/8-4-stable:config/gitlab.yml.example

Init script

We updated the init script for GitLab in order to set a specific PATH for gitlab-workhorse.

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

8. Start application

sudo service gitlab start
sudo service nginx restart

9. 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:

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 (8.3)

1. Revert the code to the previous version

Follow the upgrade guide from 8.2 to 8.3, 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.
