本分分享 GitLab 降級的流程和注意事項。極狐GitLab 為 GitLab 的中文發行版，本文以私有化部署的極狐GitLab 為例來演示整個過程。

【極狐GitLab 推出 GitLab 老舊版本的專業升級服務，可以讓 12.x、13.x、14.x、15.x 等老舊版本的升級平滑不出問題】

首先確定當前的版本資訊，在例項 URL 後面加 /help就可以檢視：

file

當前例項為 17.5.1-jh。我們降級到 17.4.0-jh。

降級之前需要做好備份，執行 gitlab-backup create即可開始備份。

# 開始備份
gitlab-backup create
2024-11-13 04:43:09 UTC -- Dumping database ...
2024-11-13 04:43:09 UTC -- Dumping PostgreSQL database gitlabhq_production ...

Please back them up manually.
2024-11-13 04:43:46 UTC -- Backup 1731472989_2024_11_13_17.5.1-jh is done.
2024-11-13 04:43:46 UTC -- Deleting backup and restore PID file at [/opt/gitlab/embedded/service/gitlab-rails/tmp/backup_restore.pid] ... done

# 檢視備份
ls -ltr /var/opt/gitlab/backups/
-rw------- 1 git git 379535360 Nov 13 04:43 /var/opt/gitlab/backups/1731472989_2024_11_13_17.5.1-jh_gitlab_backup.tar

接著執行降級的步驟，大體為：

  • 停止極狐GitLab
  • 移除當前的軟體包
  • 安裝降級之後的安裝包
  • 重新配置極狐GitLab
  • 恢復備份
  • 啟動極狐GitLab

下面我們一步步演示在 ubuntu 22.04 上如何降級安裝好的極狐GitLab 例項。

整體步驟

停止極狐GitLab

# If running Puma
sudo gitlab-ctl stop puma

# Stop sidekiq
sudo gitlab-ctl stop sidekiq

移除當前的安裝包

# If on Ubuntu: remove the current package
sudo dpkg -r gitlab-jh

安裝降級之後的安裝包

可以執行 apt-cache madison gitlab-jh找到需要降級的對應安裝包資訊。本文選擇降級到 17.4.0-jh.0。

接著執行安裝命令進行低版本極狐GitLab 的安裝：

apt install gitlab-jh=17.4.0-jh.0

安裝成功會顯示如下介面：

重新配置極狐GitLab

執行 reconfigure命令重新配置極狐GitLab

# 重新配置例項
gitlab-ctl reconfigure

# 檢視元件狀態
gitlab-ctl status

恢復資料

# 找到對應的備份檔案，恢復資料
gitlab-backup restore BACKUP=1730349575_2024_10_31_17.4.0-jh
