备份准备

两台服务器gitlab版本必须一致，本例均为12.7.8

Gitlab创建备份

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

备份完成最后提示：
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。

需手动备份的文件：

Ø /etc/gitlab/gitlab.rb 配置文件须备份

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

Ø /etc/postfix/main.cfpostfix 邮件配置备份

Ø /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：

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

定时备份

计划每天凌晨2点进行备份

1	0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

备份文件恢复

修改文件权限

1	chmod 777 1629196316_2021_08_17_12.7.8_gitlab_backup.tar

关闭相关服务

1 2	gitlab-ctl stop unicorn gitlab-ctl stop sidekiq

执行恢复

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

1	gitlab-rake gitlab:backup:restore BACKUP=1629196316_2021_08_17_12.7.8

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”

开启服务

以下几个文件需手动恢复：

Ø /etc/gitlab/gitlab.rb 配置文件

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

Ø /etc/postfix/main.cfpostfix 邮件配置备份

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

1	gitlab-ctl start

安装问题

gitlab-ctl reconfigure 出现 No such file or directory

1 2	/opt/gitlab/embedded/bin/gitlab-logrotate-wrapper: No such file or directory /opt/gitlab/embedded/service/gitlab-rails/bin/sidekiq-cluster: No such file or directory

可以从其他机器拷贝一份，也可以通过来回修改unicorn端口号自动生成文件

恢复出现Backup::Error: Backup failed
