GitLab备份与恢复 | 易学教程

因公司更换服务器服务商，服务器迁移到另外一家服务商,今天就模拟线上迁移gitlab的操作

git-A IP:192.168.82.184

git-B IP:192.168.82.184

在做备份迁移前提是版本号一样，否则会失败.

Step 1.gitlab备份 gita-A

#创建备份

$ gitlab-rake gitlab:backup:create STRATEGY=copy

#备份的文件路径

$ ll /var/opt/gitlab/backups
total 160
-rw-------. 1 git git 163840 Mar 31 04:17 1585642648_2020_03_31_12.9.1_gitlab_backup.tar

Step 2.将git-A 备份/var/opt/gitlab/backups/1585642648_2020_03_31_12.9.1_gitlab_backup.tar 复制到git-B

$ scp /var/opt/gitlab/backups/1585642648_2020_03_31_12.9.1_gitlab_backup.tar root@193.168.82.185:/var/opt/gitlab/backups/

Step 3.gitlab恢复

说明：恢复前需要先停掉数据连接服务

#git-B 操作

$ gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up

$ gitlab-ctl stop sidekiq
ok: down: sidekiq: 1s, normally up

1.修改权限，600没有权限恢复

$ ls -lh /var/opt/gitlab/backups/

total 160K
-rw-------. 1 root root 160K Mar 31 04:17 1585642648_2020_03_31_12.9.1_gitlab_backup.tar


$ chmod 777 /var/opt/gitlab/backups/1585642648_2020_03_31_12.9.1_gitlab_backup.tar

2.恢复

说明：会有两次需要输入yes

$ gitlab-rake gitlab:backup:restore BACKUP=1585642648_2020_03_31_12.9.1

This task will now rebuild the authorized_keys file.
You will lose any data stored in the authorized_keys file.
Do you want to continue (yes/no)? yes

Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data 
and are not included in this backup. You will need to restore these files manually.
Restore task is done.

3.重启gitlab

$ gitlab-ctl start unicorn
$ gitlab-ctl start sidekiq

4.访问git-A & git-B

说明：git-A 做备份前时创建了一个项目testprojects，备份恢复到git-B数据一样.
