rhel6.x的双机互信搭建

双机互信的搭建

1准备的工作

两台主机node1  192.168.1.60

       node2  192.168.1.80

2，node1的准备工作

[root@localhost ~]# ssh-keygen -t rsa

[root@localhost ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@centos

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added '192.168.1.80' (RSA) to the list of known hosts.

^C[root@localhost ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]

[root@localhost ~]# setenforce 0    //要关闭selinux防火墙

[root@localhost ~]# ssh 192.168.1.80 'ifconfig'  //在node2上执行ifconfig命令

Address 192.168.1.60 maps to bogon, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

         inet addr:192.168.1.80  Bcast:192.168.1.255  Mask:255.255.255.0

3，node2的准备工作

[root@localhost ~]# ssh-keygen -t rsa

The key's randomart image is:
