Gitlab的备份和恢复

1、gitlab的备份

sh
#备份配置文件命令
gitlab-ctl backup-etc --backup-path <DIRECTORY>
#如果不指定--backup-path <DIRECTORY>，则默认备份至/etc/gitlab/config_backup/

----------例：-----------
[root@ubuntu1804 ~]#gitlab-ctl backup-etc
Could not find '/etc/gitlab/config_backup' directory. Creating.
Running configuration backup
Creating configuration backup archive: gitlab_config_1627267534_2021_07_26.tar
/etc/gitlab/
/etc/gitlab/gitlab.rb
/etc/gitlab/gitlab-secrets.json
/etc/gitlab/trusted-certs/
Configuration backup archive complete:
/etc/gitlab/config_backup/gitlab_config_1627267534_2021_07_26.tar
Keeping all older configuration backups
[root@ubuntu1804 ~]#ls /etc/gitlab/config_backup/
gitlab_config_1627267534_2021_07_26.tar
[root@ubuntu1804 ~]#tar tvf /etc/gitlab/config_backup/gitlab_config_1627267534_2021_07_26.tar
drwxrwxr-x root/root         0 2021-07-26 10:45 /etc/gitlab/
-rw------- root/root    121857 2021-07-26 09:36 /etc/gitlab/gitlab.rb
-rw------- root/root     19021 2021-07-26 09:40 /etc/gitlab/gitlab-secrets.json
drwxr-xr-x root/root         0 2021-07-26 09:37 /etc/gitlab/trusted-certs/

#不同版本的备份数据命令
#GitLab 12.2之后版本，默认备份保存在/var/opt/gitlab/backups/下
gitlab-backup create
#GitLab 12.1之前版本，
gitlab-rake gitlab:backup:create

---------备份相关配置---------
#默认在/etc/gitlab/gitlab.rb文件中指定备份路径，如果目录空间不足，可以修改新的目录
#注意：修改完配置需要执行gitlab-ctl reconfigure
# gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"
#备份的文件权限，所有者和所属组为git
# gitlab_rails['backup_archive_permissions'] = 0644
#默认备份过期时长为7天，单位为s, 之后会被自动删除
#gitlab_rails['backup_keep_time'] = 604800

2、gitlab的恢复操作

sh
------恢复的前提条件------
备份和恢复使用的版本要一致
还原相关配置文件后，执行gitlab-ctl reconfigure
确保gitlab正在运行状态

--------新版恢复方法--------
#恢复前先停止两个服务
[root@ubuntu1804 ~]#gitlab-ctl stop puma
[root@ubuntu1804 ~]#gitlab-ctl stop sidekiq
#恢复时指定备份文件的时间部分，不需要指定文件的全名
[root@ubuntu1804 ~]#gitlab-backup restore BACKUP=备份文件名的时间部分

-------例：-------
[root@ubuntu1804 ~]#gitlab-backup restore BACKUP=1583562898_2020_03_07_11.11.8
#Next, restore /etc/gitlab/gitlab-secrets.json if necessary, as previously
mentioned.Reconfigure, restart and check GitLab:

#如果配置文件未修改，此步骤可省略，或者还原配置文件再重新载入
[root@ubuntu1804 ~]#gitlab-ctl reconfigure
[root@ubuntu1804 ~]#gitlab-ctl restart
#观察日志，等待恢复完成，需要再等一会儿再验证是否恢复

#后续检查可选做
[root@ubuntu1804 ~]#gitlab-rake gitlab:check SANITIZE=true
#In GitLab 13.1 and later, check database values can be decrypted especially if
/etc/gitlab/gitlab-secrets.json was restored, or if a different server is the
target for the restore.
[root@ubuntu1804 ~]#gitlab-rake gitlab:doctor:secrets

----------确保还原完成----------
恢复后，项目及用户信息都已还原
注意：可能需要等一段时间才能打开浏览器进行访问
