        查看48机器ssh_config配置文件中 PasswordAuthentication值为yes, 说明已经开启了ssh密码登录, 手动执行scp输入密码可以远程拷贝成功:

        报密码错误, 因为执行scp的shell脚本中没有输入48的密码, 所以是没有配置ssh免密码登录, 或是之前配置的免密码登录失效了.

        设置ssh免密码登录. 

        将44机器上的id_rsa.pub复制到48机器.ssh目录下:

root@mach4:/var/log# scp /root/.ssh/id_rsa.pub root@192.168.0.48:~/.ssh/abc
root@192.168.0.48's password: 
id_rsa.pub   

root@mach8:~/.ssh# cat ./abc >> ./authorized_keys
