Gitlab备份与恢复

给Gitlab做下数据保障

无奈自建的服务总是要考虑这考虑那，嘎嘎埋埋，成本掂过67…..

事前准备

和部门人员嗦一句，准备停服了，靓仔们

创建本地备份目录

[root@ks-gitlab ~]# mkdir -p /var/opt/gitlab/backups && chown git.git /var/opt/gitlab/backups

配置Gitlab备份参数

# 编辑配置文件如下
[root@ks-gitlab ~]# vim /etc/gitlab/gitlab.rb

....略
gitlab_rails['manage_backup_path'] = true
gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"

###! Docs: https://docs.gitlab.com/ee/raketasks/backup_restore.html#backup-archive-permissions
gitlab_rails['backup_archive_permissions'] = 0644

gitlab_rails['backup_pg_schema'] = 'public'

###! The duration in seconds to keep backups before they are allowed to be deleted
gitlab_rails['backup_keep_time'] = 2592000
....略

编辑完后还需要重配置并重启

[root@ks-gitlab ~]# gitlab-ctl reconfigure

如果没有意外那就正常启动的(～￣▽￣)～

手动触发备份

[root@ks-gitlab ~]# cd /var/opt/gitlab/backups
[root@ks-gitlab backups]# gitlab-rake gitlab:backup:create
