每次连接都要输入密码
上面链接配置文件名字错了，应为vim /etc/ssh/sshd_config
操作命令过程：
[root@mcw1 ~]# ls .ssh/
ls: cannot access .ssh/: No such file or directory
[root@mcw1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory ‘/root/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Od+6HjBBrHeUA5MP8rwckdakM89XrZNf0/kOjRPB4eI root@mcw1
The key‘s randomart image is:
+---[RSA 2048]----+

| *== .. = .|
| . =Bo. o +o|
| oS+o E =oo|

[root@mcw1 ~]# ls .ssh/

host_ip.txt文件可以通过手动写（当然了这就显得不自动化）你可以使用扫描工具扫描你网络中的主机，然后配合awk等工具生成该文件。ip地址即登录用户名密码的文件实例：
这样就能批量执行命令了：
