gitlab数据迁移

由于Gitlab自身的兼容性问题，高版本的Gitlab无法恢复低版本备份的数据,需要注意在b服务器部署和a服务器一样版本的gitlab
查看gitlab版本的命令:

[root@xxxx ~]# gitlab-rake gitlab:env:info

备份原192.168.0.108服务器上的的数据

gitlab-rake gitlab:backup:create RAILS_ENV=production

备份后的文件一般是位于/var/opt/gitlab/backups下, 自动生成文件名文件名如1558334901_2019_05_20_10.3.4_gitlab_backup.tar

将生成的tar文件拷贝到192.168.0.246服务器上相应的backups目录下
可以利用scp进行直接拷贝.

scp root@192.168.0.108:/var/opt/gitlab/backups/1558334901_2019_05_20_10.3.4_gitlab_backup.tar /var/opt/gitlab/backups

在192.168.0.246服务器恢复数据

gitlab-rake gitlab:backup:restore RAILS_ENV=production BACKUP=1558334901_2019_05_20_10.3.4
