一.GitLab的数据备份
1>.查看GitLab默认存储数据的目录
[root@gitlab201.yinzhengjie.org.cn ~]# ll /var/opt/gitlab/git-data/ total 12 drwx------ 3 git root 4096 Mar 13 04:43 ./ drwxr-xr-x 21 root root 4096 Mar 13 10:08 ../ drwxrws--- 4 git root 4096 Mar 18 10:25 repositories/ [root@gitlab201.yinzhengjie.org.cn ~]#
2>.停止GitLab的数据服务
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl status run: alertmanager: (pid 18999) 0s; run: log: (pid 1630) 642s run: gitaly: (pid 1699) 641s; run: log: (pid 1618) 642s run: gitlab-exporter: (pid 1697) 641s; run: log: (pid 1620) 642s run: gitlab-workhorse: (pid 1695) 641s; run: log: (pid 1631) 642s run: grafana: (pid 1690) 641s; run: log: (pid 1625) 642s run: logrotate: (pid 1696) 641s; run: log: (pid 1623) 642s run: nginx: (pid 1692) 641s; run: log: (pid 1621) 642s run: node-exporter: (pid 1638) 642s; run: log: (pid 1624) 642s run: postgres-exporter: (pid 1689) 641s; run: log: (pid 1628) 642s run: postgresql: (pid 1693) 641s; run: log: (pid 1619) 642s run: prometheus: (pid 1687) 641s; run: log: (pid 1626) 642s run: redis: (pid 1698) 641s; run: log: (pid 1617) 642s run: redis-exporter: (pid 1686) 641s; run: log: (pid 1627) 642s run: sidekiq: (pid 1694) 641s; run: log: (pid 1629) 642s run: unicorn: (pid 1691) 641s; run: log: (pid 1622) 642s [root@gitlab201.yinzhengjie.org.cn ~]#
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl stop unicorn ok: down: unicorn: 0s, normally up [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl stop sidekiq ok: down: sidekiq: 0s, normally up [root@gitlab201.yinzhengjie.org.cn ~]#
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl status run: alertmanager: (pid 18999) 0s; run: log: (pid 1630) 791s run: gitaly: (pid 1699) 790s; run: log: (pid 1618) 791s run: gitlab-exporter: (pid 1697) 790s; run: log: (pid 1620) 791s run: gitlab-workhorse: (pid 1695) 790s; run: log: (pid 1631) 791s run: grafana: (pid 1690) 790s; run: log: (pid 1625) 791s run: logrotate: (pid 1696) 790s; run: log: (pid 1623) 791s run: nginx: (pid 1692) 790s; run: log: (pid 1621) 791s run: node-exporter: (pid 1638) 791s; run: log: (pid 1624) 791s run: postgres-exporter: (pid 1689) 790s; run: log: (pid 1628) 791s run: postgresql: (pid 1693) 790s; run: log: (pid 1619) 791s run: prometheus: (pid 1687) 790s; run: log: (pid 1626) 791s run: redis: (pid 1698) 790s; run: log: (pid 1617) 791s run: redis-exporter: (pid 1686) 790s; run: log: (pid 1627) 791s down: sidekiq: 71s, normally up; run: log: (pid 1629) 791s down: unicorn: 84s, normally up; run: log: (pid 1622) 791s [root@gitlab201.yinzhengjie.org.cn ~]#
3>.手动备份数据
[root@gitlab201.yinzhengjie.org.cn ~]# ll /var/opt/gitlab/backups/ total 8 drwx------ 2 git root 4096 Mar 13 04:43 ./ drwxr-xr-x 21 root root 4096 Mar 13 10:08 ../ [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# gitlab-rake gitlab:backup:create 2020-03-18 10:37:04 +0000 -- Dumping database ...

[root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# ll /var/opt/gitlab/backups/ total 168 drwx------ 2 git root 4096 Mar 18 10:37 ./ drwxr-xr-x 21 root root 4096 Mar 13 10:08 ../ -rw------- 1 git git 163840 Mar 18 10:37 1584527828_2020_03_18_12.8.6_gitlab_backup.tar [root@gitlab201.yinzhengjie.org.cn ~]#
4>.启动GitLab服务
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl start ok: run: alertmanager: (pid 24886) 1352s ok: run: gitaly: (pid 1699) 1352s ok: run: gitlab-exporter: (pid 1697) 1352s ok: run: gitlab-workhorse: (pid 1695) 1352s ok: run: grafana: (pid 1690) 1352s ok: run: logrotate: (pid 1696) 1352s ok: run: nginx: (pid 1692) 1352s ok: run: node-exporter: (pid 1638) 1353s ok: run: postgres-exporter: (pid 1689) 1352s ok: run: postgresql: (pid 1693) 1352s ok: run: prometheus: (pid 1687) 1352s ok: run: redis: (pid 1698) 1352s ok: run: redis-exporter: (pid 1686) 1352s ok: run: sidekiq: (pid 24907) 0s ok: run: unicorn: (pid 24914) 0s [root@gitlab201.yinzhengjie.org.cn ~]#
5>.查看GitLab的WebUI
二.模拟删除数据
1>.访问项目目录，如下图所示，点击"index.html"文件
2>.如下图所示，点击"Delete"
3>.点击"Delete file"文件
删除成功后，会有如下图所示的提示信息。
三.利用第一步备份GitLab的数据进行恢复操作
1>.恢复数据之前，先停止数据服务
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl stop unicorn ok: down: unicorn: 1s, normally up [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl stop sidekiq ok: down: sidekiq: 0s, normally up [root@gitlab201.yinzhengjie.org.cn ~]#
2>.执行恢复数据的命令
[root@gitlab201.yinzhengjie.org.cn ~]# ll /var/opt/gitlab/backups/ total 168 drwx------ 3 git root 4096 Mar 18 11:05 ./ drwxr-xr-x 21 root root 4096 Mar 13 10:08 ../ -rw------- 1 git git 163840 Mar 18 10:37 1584527828_2020_03_18_12.8.6_gitlab_backup.tar [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# gitlab-rake gitlab:backup:restore BACKUP=1584527828_2020_03_18_12.8.6 #指定要恢复的版本,注意BACKUP的名称格式为:unix时间戳_年_月_日_GitLab的版本号
3>.如下图所示,第一个提示信息输入"yes"
4>.如下图所示,第二个提示信息依旧输入"yes"
5>.再次启动GitLab的数据服务
[root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl start unicorn ok: run: unicorn: (pid 37482) 0s [root@gitlab201.yinzhengjie.org.cn ~]# [root@gitlab201.yinzhengjie.org.cn ~]# gitlab-ctl start sidekiq ok: run: sidekiq: (pid 37595) 1s [root@gitlab201.yinzhengjie.org.cn ~]#
6>.再次查看GitLab的WebUI，如下图所示
