GitLab备份
1、设置gitlab备份目录
vim /etc/gitlab/gitlab.rb
gitlab_rails['backup_path'] = "/opt/gitlab_bak"
加载配置文件
gitlab-ctl reconfigure
2、创建备份
gitlab-rake gitlab:backup:create

查看备份文件
ll /opt/gitlab_bak
total 448436 -rw------- 1 git git 229591040 Jan 27 21:30 1643290228_2022_01_27_14.6.3-ee_gitlab_backup.tar
3、数据还原
注意：数据恢复时，gitlab的版本要与原备份的gitlab版本一致
停止数据连接服务
注意，不能执行gitlab-ctl stop,直接停掉gitlab服务，因为gitlab还原需要用到redis和postgresql连接
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
进行数据恢复
注意备份文件的权限，要设置为git：
chown -R git:git /opt/gitlab_bak/1654781429_2022_06_09_14.8.2-ee_gitlab_backup.tar
还原命令：
gitlab-rake gitlab:backup:restore BACKUP=1643895551_2022_02_03_14.6.3-ee 备份文件名称的前半部分
注意，通过这种方法将gitlab迁移到新主机上时，在修改项目信息或者删除项目时会报500错误：
这是由于前后的token不一致导致的，需要进入gitlab的数据库将token信息清除掉
进入gitlab数据库：适配14.8.2-ee版本，其他版本的命令可能不一致
gitlab-rails dbconsole --database main
执行以下命令，将token进行删除：
UPDATE projects SET runners_token = null, runners_token_encrypted = null;
UPDATE namespaces SET runners_token = null, runners_token_encrypted = null;
UPDATE application_settings SET runners_registration_token_encrypted = null;
刷新页面，500错误消失，修改成功
