一、?? 备份之前

两台服务器gitlab版本必须一致,本例均为12.10.11

二、?? Gitlab创建备份

#创建备份文件

[root@localhost backups]# gitlab-rake gitlab:backup:create

Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data?and are not included in this backup. You will need these files to restore a backup.??Please back them up manually.Backup task is done.

红字部分表示?gitlab.rb 和 gitlab-secrets.json 两个文件包含敏感信息。未被备份到备份文件中。需要手动备份。

使用以上命令会在/var/opt/gitlab/backups目录下创建一个名称类似为1621612926_2021_05_21_12.10.11_gitlab_backup.tar的压缩包, 这个压缩包就是Gitlab整个的完整部分。

[root@localhost backups]# ls -l

-rw------- 1 git git 2969600 May 21 10:40 1621608054_2021_05_21_12.10.11_gitlab_backup.tar

-rw------- 1 git git 2969600 May 21 12:02 1621612926_2021_05_21_12.10.11_gitlab_backup.tar

需手动备份的文件:

?? /etc/gitlab/gitlab.rb 配置文件须备份

?? /var/opt/gitlab/nginx/conf nginx配置文件

?? /etc/postfix/main.cfpostfix 邮件配置备份

?? ?/etc/gitlab/gitlab-secrets.json 存储了gitlab的db secret信息

??如果想修改备份路径,可在/etc/gitlab/gitlab.rb文件下编辑

gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"

三、?? 定时备份

计划每天凌晨五点进行备份

?

[root@localhost ~]# crontab -l

0 5 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

四、??? 备份迁移

??本例是通过scp命令将源备份数据复制至新服务器之下,由于有端口限制,故对端口进行了处理:

源端服务器

[root@localhost backups]# scp -P 12018 /var/opt/gitlab/backups/1621846817_2021_05_24_12.10.11_gitlab_backup.tar root@10.78.56.115:/var/opt/gitlab/backups/

root@10.78.56.115's password:

1621612926_2021_05_21_12.10.11_gitlab_backup.tar?????????????????????????????????????????? 100% 2900KB?? 3.5MB/s?? 00:00

注意:

l? 新服务器的gitlab版本和老服务器的gitlab版本一致

l? scp -P 端口,这个P是大写

五、??? 备份文件恢复

1.? 修改文件权限

[root@cqgitlab backups]# chmod 777 1621846817_2021_05_24_12.10.11_gitlab_backup.tar

2.? 关闭相关服务

关闭数据库连接服务

[root@cqgitlab backups]# gitlab-ctl stop unicorn

ok: down: unicorn: 0s, normally up

[root@cqgitlab backups]# gitlab-ctl stop sidekiq

ok: down: sidekiq: 0s, normally up

[root@cqgitlab backups]# gitlab-ctl stop nginx

ok: down: nginx: 1s, normally up

?这里注意不要关闭gitlab所有服务(gitlab-ctl stop),否则会报错:

Gitlab数据备份和恢复_Gitlab

3.? 执行恢复

??gitlab-rake gitlab:backup:restore BACKUP=备份文件编号

[root@cqgitlab backups]# gitlab-rake gitlab:backup:restore BACKUP=1621846817_2021_05_24_12.10.11

??注意:

l? 此处命令是文件编号,不是文件名称

l? 交互界面会有两次让输入“yes”

Gitlab数据备份和恢复_Gitlab_02Gitlab数据备份和恢复_Gitlab_03


4.? 开启服务

以下几个文件需手动恢复:

?? /etc/gitlab/gitlab.rb 配置文件

?? /var/opt/gitlab/nginx/conf nginx配置文件

?? /etc/postfix/main.cfpostfix 邮件配置备份

?? ?/etc/gitlab/gitlab-secrets.json 存储了gitlab的db secret信息

[root@cqgitlab gitlab]# mv /tmp/gitlab* .? #将备份在tmp目录下的文件手动进行恢复

[root@cqgitlab backups]# gitlab-ctl start

ok: run: alertmanager: (pid 12840) 1696s

ok: run: gitaly: (pid 12857) 1696s

ok: run: gitlab-exporter: (pid 12888) 1695s

ok: run: gitlab-workhorse: (pid 12893) 1695s

ok: run: grafana: (pid 12904) 1694s

ok: run: logrotate: (pid 12924) 1694s

ok: run: nginx: (pid 12947) 1693s

ok: run: node-exporter: (pid 12965) 1693s

ok: run: postgres-exporter: (pid 12971) 1693s

ok: run: postgresql: (pid 12984) 1692s

ok: run: prometheus: (pid 12993) 1692s

ok: run: redis: (pid 13014) 1691s

ok: run: redis-exporter: (pid 13025) 1691s

ok: run: sidekiq: (pid 25051) 0s

ok: run: unicorn: (pid 25057) 1s

检查状态

?Gitlab数据备份和恢复_Gitlab_04

都无问题,两边的Gitlab同步完成,数据一致
