实现脚本自动备份Gitlab档案并同步到远程

参考：Gitlab的备份与恢复

Gitlab服务器与备份服务器进行密钥配对，免密使用scp传输Gitlab备份文件

Gitlab Server: 192.168.0.55
Bakcup SWerver: 192.168.0.222

• 在Gitlab服务器上生产密钥对

ssh-keygen -t rsa

• 拷贝Gitlab上的公钥上传到备份服务器的指定目录（~/.ssh/authorized_keys）:默认为当前用户的.ssh/authorized_keys文件内，笔者使用的是root账户

# 在gitlab上执行，如果端口不是默认的22，采用scp的方式拷贝gitlab公钥
ssh-copy-id root@192.168.0.222

创建shell定时备份Gitlab档案到远程脚本

定时执行脚本（crontab）

• 编辑/etc/crontab

# 在crontab文件中添加对应定时任务
# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed

# add by wanghui,每天凌晨两点备份Gitlab
#m h d m w

• 重启cron任务

/etc/init.d/crond reload
/etc/init.d/crond restart 

• 定时删除备份服务器上的备份文件
