Gitlab 迁移恢复数据

背景：腾讯云先买了一台服务器，双十一发现有更优惠的，果断退款备份文件，重新购买
前提条件：新旧gitlab的版本一致，可参考我的另外一篇文章，安装gitlab并汉化
1.备份原gitlab的文件

gitlab-rake gitlab:backup:create
#备份完成，CD进去看一下备份结果
cd /var/opt/gitlab/backups
ls -l
total 244
-rw-r--r-- 1 git git 245760 Nov 12 15:33 1604389250_2020_11_03_12.3.5_gitlab_backup.tar

将改文件下载到本地，同时，备份配置文件（rb和关键的json）

cd /etc/gitlab
[root@VM-0-17-centos gitlab]# ls -l
total 116
-rw------- 1 root root 95205 Nov  3 17:07 gitlab.rb
-rw------- 1 root root 15611 Nov  3 17:27 gitlab-secrets.json
drwxr-xr-x 2 root root  4096 Nov  3 16:51 trusted-certs

备份gitlab.rb(可选)和gitlab-secrets.json(必须备份，不然恢复时系统异常)
将3个文件传到服务器，新服务器装好后，先运行一下，进去设置默认密码
开始上传文件至新服务器，对应文件传至对应目录，给777 root权限
重要！！！
执行gitlab恢复命令，此处请不要gitlab-cli stop，会无法恢复，提示找不到sock

直接执行恢复命令，不要stop gitlab

gitlab-rake gitlab:backup:restore BACKUP=1604389250_2020_11_03_12.3.5

输入2次交互的YES，等待恢复成功

恢复成功后，最好重启一些，恢复完成
