gitlab的备份与恢复与迁移

一.gitlab的备份
1.1 创建备份目录,并授权

[root@linux-node1 ~]# mkdir /data/backups/gitlab -p
[root@linux-node1 ~]# chown -R git.git /data/
[root@linux-node1 ~]# ll /data/ -d
drwxr-xr-x 3 git git 20 Dec 20 16:21 /data/
1.2 修改gitlab配置

设置备份路径
[root@7mini-node1 ~]# vim /etc/gitlab/gitlab.rb
201 gitlab_rails['backup_path'] = "/data/backups/gitlab"   #备份路径
204 gitlab_rails['backup_keep_time'] = 604800   #备份7天
 
 
[root@7mini-node1 ~]# mkdir -p /data/backups/gitlab
[root@7mini-node1 ~]# gitlab-ctl reconfigure
[root@7mini-node1 ~]# gitlab-ctl restart

1.3.定时任务备份

1
2
[root@7mini-node1 ~]# crontab -l
0 2 * * *  /usr/bin/gitlab-rake  gitlab:backup:create

1.4.手动执行脚本进行备份

[root@7mini-node1 ~]# cd /data/backups/gitlab/
[root@7mini-node1 gitlab]# ls
1525934310_gitlab_backup.tar
[root@7mini-node1 gitlab]# ll
total 80
-rw------- 1 git git 81920 May 10 14:38 1525934310_gitlab_backup.tar
[root@7mini-node1 gitlab]# date -d @1525934310

1.5 恢复备份

删除gitlab中的app1的项目,再恢复
停止数据写入服务:

4
[root@7mini-node1 ~]# gitlab-ctl stop unicorn
ok: down: unicorn: 1s, normally up
[root@7mini-node1 ~]# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
恢复数据
1
2
[root@7mini-node1 ~]# gitlab-rake gitlab:backup:restore BACKUP=1525934310
[root@7mini-node1 ~]# gitlab-ctl restart

丢失的文件又还原了 

 gitlab的备份与恢复与迁移

二.gitlab迁移

迁移如同备份与恢复的步骤一样, 只需要将老服务器/var/opt/gitlab/backups目录下的备份文件拷贝到新服务器上的/var/opt/gitlab/backups即可(如果你没修改过默认备份目录的话). 
但是需要注意的是新服务器上的Gitlab的版本必须与创建备份时的Gitlab版本号相同.(注意必须相同,否则会出现问题的)

比如新服务器安装的是最新的9.52版本的Gitlab, 那么迁移之前, 可以将老服务器的Gitlab 升级为9.52在进行备份

1
2
/etc/gitlab/gitlab.rb gitlab  配置文件须迁移,迁移后需要调整数据存放目录
/var/opt/gitlab/nginx/conf     nginx配置文件目录须迁移

还原

[root@linux-node1 ~]# gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up
[root@linux-node1 ~]# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
[root@linux-node1 ~]# chmod 777 /var/opt/gitlab/backups/1481598919_gitlab_backup.tar
[root@linux-node1 ~]# gitlab-rake gitlab:backup:restore BACKUP=1481598919

  

三.gitlab升级与出现问题解决办法

下载gitlab的RPM包并进行升级

1
2
官网下载最新版本 gitlab对应软件包  [gitlab官网](https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-8.12.13-ce.0.el7.x86_64.rpm)
使用 rpm -Uvh gitlab-ce-8.12.13-ce.0.el7.x86_64

如果直接升级出现如下报错

1
2
3
4
报错.
Error executing action `run` on resource 'ruby_block[directory resource: /var/opt/gitlab/git-data/repositories]'
解决方法:
sudo chmod 2770 /var/opt/gitlab/git-data/repositories

查看版本信息

1
2
[root@localhost backups]# head -1 /opt/gitlab/version-manifest.txt
gitlab-ce 9.5.2

四.gitlab更改默认Nginx

  更换gitlab自带Nginx,使用自行编译Nginx来管理gitlab服务。

编辑gitlab配置文件禁用自带Nignx服务器

1
2
3
4
5
vi /etc/gitlab/gitlab.rb
...
#设置nginx为false,关闭自带Nginx
nginx['enable'] = false
...

  检查默认nginx配置文件,并迁移至新Nginx服务

1
2
/var/opt/gitlab/nginx/conf/nginx.conf          #nginx配置文件,包含gitlab-http.conf文件
/var/opt/gitlab/nginx/conf/gitlab-http.conf    #gitlab核心nginx配置文件

 

重启 nginx、gitlab服务

1
2
gitlab-ctl reconfigure
service nginx restart

出现502报错

1
chmod -R o+x /var/opt/gitlab/gitlab-rails

  

五. gitlab邮箱的配置

126邮件配置:
gitlab_rails['time_zone'] = 'Asia/Shanghai'
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = 'xiaoming@126.com'  #发件邮箱设置
gitlab_rails['gitlab_email_display_name'] = 'gitlab'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.126.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "xiaoming"
gitlab_rails['smtp_password'] = "your password"
gitlab_rails['smtp_domain'] = "126.com"
gitlab_rails['smtp_authentication'] = "login"
