gitlab-ce-omnibus社区版的备份、还原及升级

gitlab-ce-omnibus社区版的备份和还原,可以使用gitlab自带工具,gitlab-rake来完成,详见下面例子

将旧gitlab服务器备份,并还原至新gitlab服务器 ,这两台gitlab服务器必须要同版本,才能还原成功

旧gitlab服务器

  • 更改gitlab备份文件存放位置

vim /etc/gitlab/gitlab.rb

gitlab_rails['backup_path'] = "/mnt"
#该地址是配置存放备份的地方,根据实际情况配置,可以指定为已经挂载好的nfs目录,便于边备份边传输至新gitlab服务器。

gitlab-ctl reconfigure
  • 备份旧gitlab服务器的数据,密钥文件及ssh文件,停止旧gitlab服务

gitlab-rake gitlab:backup:create
#在备份数据巨大,备份路径是网络路径情况下,比较耗时。

cp  /etc/gitlab/gitlab-secrets.json  /mnt/
cp  /etc/ssh/*key*  /mnt/


#gitlab密钥及服务器密钥,在进行gitlab完整迁移和完整还原,是必须要备份的。


gitlab-ctl stop

新gitlab服务器

  • 停止与数据库的连接

gitlab-ctl reconfigure
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
# Verify
gitlab-ctl status
  • 恢复数据及配置至新gitlab主服务器

chown git:git 1564156142_2019_07_26_10.4.3_gitlab_backup.tar
gitlab-rake gitlab:backup:restore backup=timestamp #timesstamp是指gitlab备份包的文件名前面的一串数字,如1564156142
# 如报下面的错误就是文件权限问题导致的

Unpacking backup ... tar: 1564156142_2019_07_26_10.4.3_gitlab_backup.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now



cp -f  /mnt/gitlab-secrets.json  /etc/gitlab/
cp -f /mnt/*key*  /etc/ssh/

 

# key认证问题

可能报错:

报错情况1:(key没有从master复制过来)

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:9DdK4jo9LPLg7snd/vueT3wI2dy0hb7CVYRRGOTU8TY.
Please contact your system administrator.
Add correct host key in /c/Users/cd/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/cd/.ssh/known_hosts:4
ECDSA host key for git.tuandai888.com has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

 

报错情况2:(从master复制过来的key权限没设置好)

ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

 

解决方法:

把master的 /etc/ssh/*key* 文件全部复制到从节点来,并注意权限与master的设置一样,

scp root@[master_IP]:/etc/ssh/*key* /etc/ssh

chown root:ssh_keys ssh_host_ecdsa_key ssh_host_ed25519_key ssh_host_rsa_key

 

  • 重启gitlab服务,并验证

gitlab-ctl restart 
gitlab-rake  gitlab:check SANITIZE=true
#检查新gitlab服务器刚刚导入的数据

gitlab-ctl reconfigure
  • 验证新gitlab主服务器的用户,代码库,提交记录等等是否完整,测试各项操作

  • 递进升级到目前最新的稳定版本

列出当前gitlab所有版本

 yum list gitlab-ce.x86_64  --showduplicates | sort -r 
 
#先升级到当前安装主版本的最后一个子版本,再升级到下一个主版本的合适的子版本。
#升级完一个版本后,确认无报错,数据正常,再升级到下一个版本。
 
#下面就是从7.x.x升级到10.x.x的升级方法 
 yum install -y gitlab-ce-7.14.3-ce.1.el7 
  
 yum install -y gitlab-ce-8.17.8-ce.0.el7
 
 yum install -y gitlab-ce-9.5.9-ce.0.el7 
 
 yum install -y gitlab-ce-10.3.5-ce.0.el7 


gitlab-ctl restart
