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
[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
/usr/bin/gitlab-rake gitlab:backup:create Dumping database ... Dumping PostgreSQL database gitlabhq_production ... [DONE] done Dumping repositories ... * java/app1 ... [DONE] * java/app1.wiki ... [SKIPPED] [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 Thu May 10 14:38:30 CST 2018
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:
[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
[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
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
/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
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
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
[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
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
/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
gitlab-ctl reconfigure service nginx restart
出现502报错
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"
