4.Gitlab数据还原失败

原因:gitlab版本restore存在bug,目录权限问题导致还原失败。
issue:https://gitlab.com/gitlab-org/gitlab-ce/issues/46891

first:
#scp 1528963129_2018_06_14_10.8.4_gitlab_backup.tar 192.168.99.115:`pwd`
#chown git.git /var/opt/gitlab/backups/*.tar
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
gitlab-rake gitlab:backup:restore

**错误提示:**
[DONE]
done
Restoring uploads ...
tar: .: Cannot mkdir: No such file or directory
tar: Exiting with failure status due to previous errors
Backup failed

各位看官,看到该提示是不是超蛋疼,大脑飘过十万个草泥马!别急,能解决的,咱可以手动;

5. Gitlab的备份过程

其实就是使用tar打包过程,db 和 repositories 除外!! 

各位看官,说到这里是不是想起来点什么,继续往下看哦 !!!

6.数据还原过程

Unpacking backup ... done
Before restoring the database, we will remove all existing
tables to avoid future upgrade problems. Be aware that if you have
custom tables in the GitLab database these tables and all data will be
removed.

Do you want to continue (yes/no)? yes
Removing all tables. Press `Ctrl-C` within 5 seconds to abort

7.解决数据还原

#cd /var/opt/gitlab/backups
#ls 
1528963129_2018_06_14_10.8.4_gitlab_backup.tar  backup_information.yml  db                      
pages.tar.gz  tmp artifacts.tar.gz builds.tar.gz lfs.tar.gz  repositories      
uploads.tar.gz

restore handy:
#tar xf uploads.tar.gz -C /var/opt/gitlab/gitlab-rails/uploads
#tar xf builds.tar.gz -C /var/opt/gitlab/gitlab-ci/builds
#tar xf pages.tar.gz -C /var/opt/gitlab/gitlab-rails/shared/pages
#tar xf artifacts.tar.gz -C /var/opt/gitlab/gitlab-rails/shared/artifacts

看到这里是不是欣喜若狂,毕竟Gitlab是基础服务,程序员的结晶之地啊!!!

注意: db、repositories 的数据已经还原,了解本质过程很重要的,万物皆有相克!!!

如果数据还原没有提到的,请自行脑补啊,不在多做累述!!!

#以下命令对还原数据可靠性检测
#gitlab-ctl reconfigure
#gitlab-ctl restart
#gitlab-rake gitlab:check SANITIZE=true

8. 新旧域名更改redirect

#grep -rn "external_url" /etc/gitlab/gitlab.rb
  external_url "http://gitlab.xxxxx.com"
#gitlab-ctl reconfigure
#gitlab-ctl restart

redirect 问题:
    点击admin area,然后左下角setting,找到“登录限制”的 Home page URL,修改为新的域名即可!!!
