主机IP：192.168.0.155、192.168.0.156、192.168.0.158
- 修改sshd_config配置
vim /etc/ssh/sshd_config
AuthorizedKeysFile .ssh/authorized_keys
- 创建ssh密钥
ssh-keygen
id_rsa是生成的本地密钥
id_rsa.pub是生成的共享密钥，用于对方安全访问本机使用
- 拷贝共享密钥并重启服务
分别将两台机子的id_rsa.pub里面的内容拷贝到另外一台机子的authorized_keys文件中，重启sshd服务即可
192.168.0.156的id_rsa.pub
vim /root/.ssh/id_rsa.pub
