Gitlab备份和恢复操作记录
作者：互联网
前面已经介绍了Gitlab环境部署记录，这里简单说下Gitlab的备份和恢复操作记录：
1）Gitlab的备份目录路径设置
[root@code-server ~]# vim /etc/gitlab/gitlab.rb gitlab_rails['manage_backup_path'] = true gitlab_rails['backup_path'] = "/data/gitlab/backups" //gitlab备份目录 gitlab_rails['backup_archive_permissions'] = 0644 //生成的备份文件权限 gitlab_rails['backup_keep_time'] = 7776000 //备份保留天数为3个月（即90天，这里是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 如上设置了gitlab备份目录路径为/data/gitlab/backups，最后使用下面命令重载gitlab配置文件，是上述修改生效！ root@code-server ~]# gitlab-ctl reconfigure
2）GItlab备份操作（使用备份命令"gitlab-rake gitlab:backup:create"）
手动备份gitlab [root@code-server backups]# gitlab-rake gitlab:backup:create Dumping database ... Dumping PostgreSQL database gitlabhq_production ... [DONE] done Dumping repositories ... * treesign/treesign ... [DONE] * gateway/gateway ... [DONE] * treesign/treesign-doc ... [SKIPPED] * qwsign/qwsign ... [DONE] * qwsign/qwsign-doc ... [DONE] * test/test ... [DONE] done Dumping uploads ... done Dumping builds ... done Dumping artifacts ... done Dumping pages ... done Dumping lfs objects ... done Dumping container registry images ... [DISABLED] Creating backup archive: 1510471890_2017_11_12_9.4.5_gitlab_backup.tar ... 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) 然后查看下备份文件（文件权限是设定好的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 编写备份脚本，结合crontab实施自动定时备份，比如每天0点、6点、12点、18点各备份一次 [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：环境变量CRON=1的作用是如果没有任何错误发生时， 抑制备份脚本的所有进度输出 [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恢复操作
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 [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）现在通过之前的备份文件进行恢复（必须要备份文件放到备份路径下，这里备份路径我自定义的/data/gitlab/backups，默认的是/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 [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.

Do you want to continue (yes/no)? yes Deleting tmp directories ... done done done done done done done done [root@code-server backups]# 最后再次启动Gitlab [root@code-server backups]# gitlab-ctl start ok: run: gitaly: (pid 98087) 2138s ok: run: gitlab-monitor: (pid 98101) 2138s ok: run: gitlab-workhorse: (pid 98104) 2137s ok: run: logrotate: (pid 98117) 2137s ok: run: nginx: (pid 98123) 2136s ok: run: node-exporter: (pid 98167) 2136s ok: run: postgres-exporter: (pid 98173) 2136s ok: run: postgresql: (pid 98179) 2135s ok: run: prometheus: (pid 98187) 2135s ok: run: redis: (pid 98230) 2134s ok: run: redis-exporter: (pid 98234) 2134s ok: run: sidekiq: (pid 104494) 0s ok: run: unicorn: (pid 104497) 1s [root@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: gitlab-workhorse: (pid 98104) 2141s; run: log: (pid 194362) 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 [root@code-server backups]# gitlab-rake gitlab:check SANITIZE=true Checking GitLab Shell ... GitLab Shell version >= 5.3.1 ? ... OK (5.3.1) Repo base directory exists? default... yes Repo storage directories are symlinks? default... no Repo paths owned by git:root, or git:git? default... yes Repo paths access is drwxrws---? default... yes hooks directories in repos are links: ... 5/1 ... ok 6/2 ... ok 5/3 ... repository is empty 12/4 ... ok 12/5 ... ok Running /opt/gitlab/embedded/service/gitlab-shell/bin/check Check GitLab API access: OK Access to /var/opt/gitlab/.ssh/authorized_keys: OK Send ping to redis server: OK gitlab-shell self-check successful Checking GitLab Shell ...

Finished 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
