// 配置用戶權限
[root@testss share]# cd /home/git
[root@testss git]# mkdir .ssh
[root@testss git]# chmod 700 .ssh/
[root@testss git]# chmod 600 /home/git/.ssh/authorized_keys 
[root@testss git]# chown git.git .ssh/ -R

//建立雙機互信
[root@testss git]# cat ~/.ssh/id_rsa.pub > ~/.ssh/authorized_keys

// git免密登陸
[root@testss git]# cat ~/.ssh/id_rsa.pub > /home/git/.ssh/authorized_keys
