In most cases this should be the highest numbered production +tag (without rc in it).

Update Ruby + +NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be +sure to upgrade your interpreter if necessary. + +You can check which version you are running with `ruby -v`. + +Download and compile Ruby: + +```bash +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: + +```bash +sudo gem install bundler --no-ri --no-rdoc +``` + +### 4. Update Node + +GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and +it has a minimum requirement of node v4.3.0. + +You can check which version you are running with `node -v`. If you are running +a version older than `v4.3.0` you will need to update to a newer version. You +can find instructions to install from community maintained packages or compile +from source at the nodejs.org website. + + + + +Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage +JavaScript dependencies. + +```bash +curl --location https://yarnpkg.com/install.sh | bash - +``` + +More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install). + +### 5. Get latest code + +```bash +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: + +```bash +cd /home/git/gitlab + +sudo -u git -H git checkout 9-1-stable +``` + +OR + +For GitLab Enterprise Edition: + +```bash +cd /home/git/gitlab + +sudo -u git -H git checkout 9-1-stable-ee +``` + +### 6.

You can do this +via [/etc/default/gitlab]. + +[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache +[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-1-stable/lib/support/init.d/gitlab.default.example#L38 + +#### 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: + +```ruby +ActionMailer::Base.delivery_method = :smtp +``` + +See [smtp_settings.rb.sample] as an example. + +[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-0-stable/config/initializers/smtp_settings.rb.sample#L13 + +#### Init script + +There might be new configuration options available for [`gitlab.default.example`][gl-example].

Optional: install Gitaly + +Gitaly is still an optional component of GitLab. If you want to save time +during your 9.1 upgrade **you can skip this step**. + +If you have not yet set up Gitaly then follow [Gitaly section of the installation +guide](../install/installation.md#install-gitaly). + +If you installed Gitaly in GitLab 9.0 you need to make some changes in gitlab.yml. + +Look for `socket_path:` the `gitaly:` section. Its value is usually +`/home/git/gitlab/tmp/sockets/private/gitaly.socket`. Note what socket +path your gitlab.yml is using. Now go to the `repositories:` section, +and for each entry under `storages:`, add a `gitaly_address:` based on +the socket path, but with `unix:` in front. + +```yaml + repositories: + storages: + default: + path: /home/git/repositories + gitaly_address: unix:/home/git/gitlab/tmp/sockets/private/gitaly.socket + other_storage: + path: /home/git/other-repositories + gitaly_address: unix:/home/git/gitlab/tmp/sockets/private/gitaly.socket +``` + +Each entry under `storages:` should use the same `gitaly_address`. + +### 11. Start application + +```bash +sudo service gitlab start +sudo service nginx restart +``` + +### 12. Check application status + +Check if GitLab and its environment are configured correctly: + +```bash +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: + +```bash +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 (9.0) + +### 1. Revert the code to the previous version + +Follow the [upgrade guide from 8.17 to 9.0](8.17-to-9.0.md), except for the +database migration (the backup is already migrated to the previous version). + +### 2. Restore from the backup + +```bash +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. + +[yaml]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-1-stable/config/gitlab.yml.example +[gl-example]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-1-stable/lib/support/init.d/gitlab.default.example -- cgit v1.2.1
