2.6 KiB

From 3.1 to 4.0

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

Important changes

  • Support for SQLite was dropped
  • Support for Gitolite 2 was dropped
  • Projects are organized in namespaces
  • The GitLab post-receive hook needs to be updated
  • The configuration file needs to be updated
  • Availability of python2 executable

Most of projects has post-receive file as symlink to Gitolite /home/git/.gitolite/hooks/post-receive. But some of them may have a real file. In this case you should rewrite it with symlink to Gitolite hook.

I wrote a bash script which will do it automatically for you. Just make sure all path inside is valid for you

1. Stop GitLab & Resque

sudo service gitlab stop

2. Update GitLab


# Get latest code
sudo -u gitlab -H git fetch
sudo -u gitlab -H git checkout 4-0-stable

# Install gems for MySQL
sudo -u gitlab -H bundle install --without development test postgres

# Update repos permissions
sudo chmod -R ug+rwXs /home/git/repositories/
sudo chown -R git:git /home/git/repositories/

# Migrate db
sudo -u gitlab -H bundle exec rake db:migrate RAILS_ENV=production

# Enable namespaces (**Warning!** All projects in groups will be moved to subdirectories)
sudo -u gitlab -H bundle exec rake gitlab:enable_namespaces RAILS_ENV=production

3. Update post-receive hooks (Requires Gitolite v3 )

Step 1: Rewrite post-receive hook

sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
sudo chown git:git /home/git/.gitolite/hooks/common/post-receive

Step 2: Update project hooks to be symlinks to the Gitolite hook

# 1. Check paths in script
sudo -u gitlab -H vim lib/support/rewrite-hooks.sh

# 2. Run script
sudo -u git -H lib/support/rewrite-hooks.sh

4. Replace config with new one

# backup old one
sudo -u gitlab -H cp config/gitlab.yml config/gitlab.yml.old

# copy new one
sudo -u gitlab -H cp config/gitlab.yml.example config/gitlab.yml

# edit it
sudo -u gitlab -H vim config/gitlab.yml

5. Disable ssh known_host check for own domain

echo "Host localhost
   StrictHostKeyChecking no
   UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config

echo "Host YOUR_DOMAIN_NAME
   StrictHostKeyChecking no
   UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config

6. Check GitLab's status

sudo -u gitlab -H bundle exec rake gitlab:check RAILS_ENV=production

7. Start GitLab & Resque

sudo service gitlab start
