解决办法
1、尝试在2个节点手工的执行测试命令：
[oracle@rac01 ~]$ ssh rac02 date
The authenticity of host 'rac02 (192.168.0.122)' can't be established.
ECDSA key fingerprint is 54:f7:6c:22:75:63:ef:d0:ba:94:f6:72:94:90:3d:fa.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'rac02,192.168.0.122' (ECDSA) to the list of known hosts.
oracle@rac02's password:
Permission denied, please try again.

[oracle@rac01 ~]$ ssh rac01 date

同样在节点2执行
[oracle@rac02 ~]$ ssh rac01 date
The authenticity of host 'rac01 (192.168.0.121)' can't be established.
ECDSA key fingerprint is 54:f7:6c:22:75:63:ef:d0:ba:94:f6:72:94:90:3d:fa.

[oracle@rac02 ~]$ ssh rac02 date

2、直接手工移除SSH的相关配置文件：
[oracle@rac01 ~]$ cd $HOME/.ssh
[oracle@rac01 .ssh]$ pwd
/home/oracle/.ssh
[oracle@rac01 .ssh]$ ll
总用量 4
-rw-r--r-- 1 oracle oinstall 362 1月 30 13:43 known_hosts

[oracle@rac01 .ssh]$ rm *
[oracle@rac01 .ssh]$ ll
总用量 0
[oracle@rac01 .ssh]$

[oracle@rac02 ~]$ cd $HOME/.ssh
[oracle@rac02 .ssh]$ ll
总用量 4
-rw-r--r-- 1 oracle oinstall 362 1月 30 13:43 known_hosts
[oracle@rac02 .ssh]$ rm *
[oracle@rac02 .ssh]$ ll
总用量 0
[oracle@rac02 .ssh]$

再执行ssh配置成功
