# From 9.3 to 9.4 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](https://about.gitlab.com/blog/archives.html) for installation guide links by version. ### 1. Stop server ```bash sudo service gitlab stop ``` ### 2. Backup ```bash cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production ``` ### 3. 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. <https://nodejs.org/en/download/> Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage JavaScript dependencies. ```bash curl --silent --show-error https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list sudo apt-get update sudo apt-get install yarn ``` More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install). ### 5. Update Go NOTE: GitLab 9.2 and higher only supports Go 1.8.3 and dropped support for Go 1.5.x through 1.7.x. Be sure to upgrade your installation if necessary. You can check which version you are running with `go version`. Download and install Go: ```bash # Remove former Go installation folder sudo rm -rf /usr/local/go curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772 go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \ sudo tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/ rm go1.8.3.linux-amd64.tar.gz ``` ### 6. 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 sudo -u git -H git checkout -- locale ``` For GitLab Community Edition: ```bash cd /home/git/gitlab sudo -u git -H git checkout 9-4-stable ``` OR For GitLab Enterprise Edition: ```bash cd /home/git/gitlab sudo -u git -H git checkout 9-4-stable-ee ``` ### 7. Update gitlab-shell ```bash cd /home/git/gitlab-shell sudo -u git -H git fetch --all --tags sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION) sudo -u git -H bin/compile ``` ### 8. Update gitlab-workhorse Install and compile gitlab-workhorse. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/). If you are not using Linux you may have to run `gmake` instead of `make` below. ```bash cd /home/git/gitlab-workhorse sudo -u git -H git fetch --all --tags sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION) sudo -u git -H make ``` ### 9. Update Gitaly If you have not yet set up Gitaly then follow [Gitaly section of the installation guide](../install/installation.md#install-gitaly). As of GitLab 9.4, Gitaly is a mandatory component of GitLab. #### Check Gitaly configuration Due to a bug in the `rake gitlab:gitaly:install` script your Gitaly configuration file may contain syntax errors. The block name `[[storages]]`, which may occur more than once in your `config.toml` file, should be `[[storage]]` instead. ```shell sudo -u git -H sed -i.pre-9.4 's/\[\[storages\]\]/[[storage]]/' /home/git/gitaly/config.toml ``` #### Compile Gitaly ```shell cd /home/git/gitaly sudo -u git -H git fetch --all --tags sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION) sudo -u git -H make ``` ### 10. Update MySQL permissions If you are using MySQL you need to grant the GitLab user the necessary permissions on the database: ```bash mysql -u root -p -e "GRANT TRIGGER ON \`gitlabhq_production\`.* TO 'git'@'localhost';" ``` If you use MySQL with replication, or just have MySQL configured with binary logging, you will need to also run the following on all of your MySQL servers: ```bash mysql -u root -p -e "SET GLOBAL log_bin_trust_function_creators = 1;" ``` You can make this setting permanent by adding it to your `my.cnf`: ``` log_bin_trust_function_creators=1 ``` ### 11. Update configuration files #### New configuration options for `gitlab.yml` There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`: ```sh cd /home/git/gitlab git diff origin/9-3-stable:config/gitlab.yml.example origin/9-4-stable:config/gitlab.yml.example ``` #### Nginx configuration Ensure you're still up-to-date with the latest NGINX configuration changes: ```sh cd /home/git/gitlab # For HTTPS configurations git diff origin/9-3-stable:lib/support/nginx/gitlab-ssl origin/9-4-stable:lib/support/nginx/gitlab-ssl # For HTTP configurations git diff origin/9-3-stable:lib/support/nginx/gitlab origin/9-4-stable:lib/support/nginx/gitlab ``` If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx configuration as GitLab application no longer handles setting it. 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]. [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/9-4-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/9-4-stable/config/initializers/smtp_settings.rb.sample#L13 #### Init script There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`: ```sh cd /home/git/gitlab git diff origin/9-3-stable:lib/support/init.d/gitlab.default.example origin/9-4-stable:lib/support/init.d/gitlab.default.example ``` Ensure you're still up-to-date with the latest init script changes: ```bash cd /home/git/gitlab sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab ``` For Ubuntu 16.04.1 LTS: ```bash sudo systemctl daemon-reload ``` ### 12. Install libs, migrations, etc. GitLab 9.4 [introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/24570) a dependency on on the `re2` regular expression library. To install this dependency: ```bash sudo apt-get install libre2-dev ``` Ubuntu 14.04 (Trusty Tahr) doesn't have the `libre2-dev` package available, but you can [install re2 manually](https://github.com/google/re2/wiki/Install). ```bash 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 # Compile GetText PO files sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production # Update node dependencies and recompile assets sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production # Clean up cache sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production ``` **MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md). ### 13. Start application ```bash sudo service gitlab start sudo service nginx restart ``` ### 14. 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 (9.3) ### 1. Revert the code to the previous version Follow the [upgrade guide from 9.2 to 9.3](9.2-to-9.3.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.
