Gitlab備份和恢復操做記錄

 

前面已經介紹了Gitlab環境部署記錄，這裏簡單說下Gitlab的備份和恢復操做記錄：

1）Gitlab的備份目錄路徑設置

[root@code-server ~]# vim /etc/gitlab/gitlab.rb
gitlab_rails['manage_backup_path'] = true
gitlab_rails['backup_path'] = "/data/gitlab/backups"    //gitlab備份目錄
gitlab_rails['backup_archive_permissions'] = 0644       //生成的備份文件權限
gitlab_rails['backup_keep_time'] = 7776000              //備份保留天數爲3個月（即90天，這裏是7776000秒）

[root@code-server ~]# mkdir -p /data/gitlab/backups
[root@code-server ~]# chown -R git.git /data/gitlab/backups
[root@code-server ~]# chmod -R 777 /data/gitlab/backups
 
如上設置了gitlab備份目錄路徑爲/data/gitlab/backups，最後使用下面命令重載gitlab配置文件，是上述修改生效！
root@code-server ~]# gitlab-ctl reconfigure

2）GItlab備份操做（使用備份命令"gitlab-rake gitlab:backup:create"）

手動備份gitlab
[root@code-server backups]# gitlab-rake gitlab:backup:create
Dumping database ... 
Dumping PostgreSQL database gitlabhq_production ... [DONE]
done
Dumping repositories ...
 * treesign/treesign ... [DONE]

done

Uploading backup archive to remote storage  ... skipped
Deleting tmp directories ... done
done
done
done
done
done
done
done
Deleting old backups ... done. (0 removed)

而後查看下備份文件（文件權限是設定好的644）
[root@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

編寫備份腳本，結合crontab實施自動定時備份，好比天天0點、6點、12點、18點各備份一次
[root@code-server backups]# pwd
/data/gitlab/backups
[root@code-server backups]# vim gitlab_backup.sh 
#!/bin/bash
/usr/bin/gitlab-rake gitlab:backup:create CRON=1

注意：環境變量CRON=1的做用是若是沒有任何錯誤發生時， 抑制備份腳本的全部進度輸出

[root@code-server backups]# crontab -l
0 0,6,12,18 * * * /bin/bash -x /data/gitlab/backups/gitlab_backup.sh > /dev/null 2>&1

3）Gitlab恢復操做

GItlab只能還原到與備份文件相同的gitlab版本。
假設在上面gitlab備份以前建立了test項目，而後不當心誤刪了test項目，如今就進行gitlab恢復操做：
 
1）中止相關數據鏈接服務
[root@code-server backups]# gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up
[root@code-server backups]# gitlab-ctl stop sidekiq
ok: down: sidekiq: 1s, normally up
[root@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）如今經過以前的備份文件進行恢復（必需要備份文件放到備份路徑下，這裏備份路徑我自定義的/data/gitlab/backups，默認的是/var/opt/gitlab/backups）
[root@code-server backups]# pwd
/data/gitlab/backups
[root@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的恢復操做會先將當前全部的數據清空，而後再根據備份數據進行恢復
[root@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)?

最後再次啓動Gitlab

run: unicorn: (pid 104497) 4s; run: log: (pid 194443) 163260s

恢復命令完成後，能夠check檢查一下恢復狀況

而後稍等一會（若是啓動gitlab後，訪問出現500，這是由於redis等程序還沒徹底啓動，等一下子訪問就ok了），再次登陸Gitlab，就會發現以前誤刪除的test項目已經恢復了！
 
另外：Gitlab遷移與恢復同樣，可是要求兩個GitLab版本號一致
