Gitlab备份和恢复操作记录

hyperv

GItlab只能还原到与备份文件相同的gitlab版本。　　
假设在上面gitlab备份之前创建了test项目，然后不小心误删了test项目，现在就进行gitlab恢复操作：
　　
1）停止相关数据连接服务
　　
[iyunv@code-server backups]# gitlab-ctl stop unicorn
　　
ok: down: unicorn: 0s, normally up
　　
[iyunv@code-server backups]# gitlab-ctl stop sidekiq
　　
ok: down: sidekiq: 1s, normally up
　　
[iyunv@code-server backups]# gitlab-ctl status
　　
run: gitaly: (pid 98087) 1883s; run: log: (pid 194202) 163003s
　　
run: gitlab-monitor: (pid 98101) 1883s; run: log: (pid 194363) 163002s
　　
run: gitlab-workhorse: (pid 98104) 1882s; run: log: (pid 194362) 163002s
　　
run: logrotate: (pid 98117) 1882s; run: log: (pid 5793) 160832s
　　
run: nginx: (pid 98123) 1881s; run: log: (pid 194359) 163002s
　　
run: node-exporter: (pid 98167) 1881s; run: log: (pid 194360) 163002s
　　
run: postgres-exporter: (pid 98173) 1881s; run: log: (pid 194204) 163003s
　　
run: postgresql: (pid 98179) 1880s; run: log: (pid 194365) 163002s
　　
run: prometheus: (pid 98187) 1880s; run: log: (pid 194364) 163002s
　　
run: redis: (pid 98230) 1879s; run: log: (pid 194358) 163002s
　　
run: redis-exporter: (pid 98234) 1879s; run: log: (pid 194208) 163003s
　　
down: sidekiq: 8s, normally up; run: log: (pid 194437) 163001s
　　
down: unicorn: 21s, normally up; run: log: (pid 194443) 163001s
　　
2）现在通过之前的备份文件进行恢复
　　
[iyunv@code-server backups]# pwd
　　
/data/gitlab/backups
　　
[iyunv@code-server backups]# ll
　　
total 244
　　
-rw-r--r-- 1 git git 245760 Nov 12 15:33 1510472027_2017_11_12_9.4.5_gitlab_backup.tar
　　
Gitlab的恢复操作会先将当前所有的数据清空，然后再根据备份数据进行恢复
　　
[iyunv@code-server backups]# gitlab-rake gitlab:backup:restore BACKUP=1510472027_2017_11_12_9.4.5
　　
Unpacking backup ... done
　　
Before restoring the database we recommend removing 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)?

最后再次启动Gitlab
　　
[iyunv@code-server backups]# gitlab-ctl start
　　
ok: run: gitaly: (pid 98087) 2138s
　　
ok: run: gitlab-monitor: (pid 98101) 2138s

ok: run: sidekiq: (pid 104494) 0s
　　
ok: run: unicorn: (pid 104497) 1s
　　
[iyunv@code-server backups]# gitlab-ctl status
　　
run: gitaly: (pid 98087) 2142s; run: log: (pid 194202) 163262s
　　
run: gitlab-monitor: (pid 98101) 2142s; run: log: (pid 194363) 163261s

run: logrotate: (pid 98117) 2141s; run: log: (pid 5793) 161091s
　　
run: nginx: (pid 98123) 2140s; run: log: (pid 194359) 163261s
　　
run: node-exporter: (pid 98167) 2140s; run: log: (pid 194360) 163261s
　　
run: postgres-exporter: (pid 98173) 2140s; run: log: (pid 194204) 163262s
　　
run: postgresql: (pid 98179) 2139s; run: log: (pid 194365) 163261s
　　
run: prometheus: (pid 98187) 2139s; run: log: (pid 194364) 163261s
　　
run: redis: (pid 98230) 2138s; run: log: (pid 194358) 163261s
　　
run: redis-exporter: (pid 98234) 2138s; run: log: (pid 194208) 163262s
　　
run: sidekiq: (pid 104494) 4s; run: log: (pid 194437) 163260s
　　
run: unicorn: (pid 104497) 4s; run: log: (pid 194443) 163260s
　　

　　
恢复命令完成后，可以check检查一下恢复情况

然后稍等一会（如果启动gitlab后，访问出现500，这是因为redis等程序还没完全启动，等一会儿访问就ok了），再次登录Gitlab，就会发现之前误删除的test项目已经恢复了！
　　
另外：Gitlab迁移与恢复一样，但是要求两个GitLab版本号一致
