    话说，ssh key 都已经生成好了么？

看上面的两个帖子即可.

主机之间互相都能SSH将会有安全隐患：任一台失守则全部完蛋

import paramiko

CMD=("mkdir -p /root/.ssh/ ; echo 'your_key'> /root/.ssh/authorized_keys ;chmod 600 /root/.ssh/authorized_keys")

IPS=['1.1.1.1','2.2.2.2']

def Remote_control(IP):
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(IP, username='jesse', password='lol')
        ssh.exec_command("%s" %CMD)

for i in IPS:
   Remote_control(i)

同意12楼的观点，其实有一台可以登录其他服务器就可以了，没必要所有的机器都要互相走密钥吧

tomer

不互走也行，那1对N互信也行啊！！

    脚本运行没有问题，
$ more hostFile
192.168.100.1 abc zcxc123 JQ1
192.168.100.2 abc zcxc123 JQ2
192.168.100.3 abc zcxc123 JQ3

# sh a -f hostFile
script starts to execute...
gererating keys and some preparation...
gererating keys and all preparation completed successfully!

authenticating for host 192.168.100.1...

authenticating for host 192.168.100.3...
authentication for host 192.168.100.3 completed successfully!

   我看用户的.ssh下也生成了 authorized_keys
   
   但是ssh登录，还要求输入密码

$ssh 192.168.100.3
abc@192.168.100.3's password:

    我刚才试了一下，root的可以
   普通用户不可以

tomer

找到原因了，需要做下权限设置
chmod 700 ~/.ssh
chmod 600 authorized_keys
