建立普通用户信任关系

1是pub文件拷过去，2是更改属主 3是600

# 创建用户目录

ssh root@$IP " /usr/sbin/useradd user1; "

# user1-user1信任

ssh root@$IP " mkdir -p /home/user1/.ssh/; chown user1:user1 /home/user1/.ssh/ "

scp -p /home/user1/.ssh/authorized_keys root@$IP:/home/user1/.ssh/

ssh root@$IP " chown user1:user1 /home/user1/.ssh/authorized_keys; chmod 600 /home/user1/.ssh/authorized_keys "
