主机： 192.168.0.21
备用机： 192.16.0.29
操作环境: CentOs7

主仓库实现已经配置好

git clone [email protected]:/home/data/git/gittest.git

备用仓库

添加用户

[root@localhost home]# id git
id: git：无此用户
[root@localhost home]# useradd git
[root@localhost home]# passwd git

进入/home/data/git目录

从远程仓库克隆镜像仓库

git clone -mirror [email protected]:/home/data/git/gittest.git

更新镜像库

git remote update

使用公钥使更新时免输密码

ssh-keygen -t rsa -C "[email protected]"

ssh [email protected] 'cat >> .ssh/authorized_keys' < /root/.ssh/id_rsa.pub

再试试

git remote update

Crontab实现定时更新

编写脚本文件

/home/data/git/sh/updategit.sh编写

#!/bin/sh
cd /home/data/git/gittest.git
git remote update >> /home/data/git/log/gitupdate.log

记得赋执行权限

chmod 755 gitupdate.sh

crontab -e
