[oracle@node1 ~]$ scp.ssh/authorized_keys node2:~/.ssh
oracle@node2's password: oracle的密码
3）验证信任关系（node1、node2）
node1上验证信任
[oracle@node1 ~]$ ssh node2date
[oracle@node1 ~]$ ssh node2-privdate //私有ip地址验证
[oracle@node1 ~]$ ssh node1date
[oracle@node1 ~]$ ssh node1-privdate
详细操作如下：
[oracle@node1 ~]$ ssh node2date
Thu May 214:46:30 CST 2013
[oracle@node1 ~]$ sshnode2-priv date //不要求输入密码代表信任成功
The authenticity of host 'node2-priv (10.10.10.2)'can't be established.
RSA key fingerprint is16:28:88:50:27:30:92:cb:49:be:55:61:f6:c2:a1:3f.
Are you sure you want to continue connecting (yes/no) yes
Warning: Permanently added 'node2-priv,10.10.10.2'(RSA) to the list of known hosts.

[oracle@node1 ~]$ sshnode2-priv date
Thu May 214:47:05 CST 2013
[oracle@node1 ~]$ ssh node1date
Thu May 214:48:19 CST 2013
[oracle@node1 ~]$ sshnode1-priv date

Thu May 214:48:35 CST 2013
[oracle@node1 ~]$ sshnode1-priv date
Thu May 214:48:36 CST 2013
node2上验证信任
[oracle@node2 ~]$ ssh node1date
[oracle@node2~]$ ssh node1-priv date
[oracle@node2 ~]$ ssh node2date
[oracle@node2~]$ ssh node2-priv date
=====Grid 用户==========================
步骤同oracle 一样，可参考oracle用户下设置
在grid用户下操作：
[root@node1 /]# su– grid
[grid@node1 ~]$mkdir .ssh 创建一个.ssh的隐藏目录
[grid@node1 ~]$ ls-al
1）生成密钥对（rsa+dsa）（node1、node2）
node1生成密钥rsa类型
id_rsa为私钥，自动保存到.ssh下
id_rsa.pub为公钥，自动保存到.ssh下
[grid@node1 ~]$ ssh-keygen-t rsa
Generating public/private rsa key pair.
Enter file in which to save the key(/home/oracle/.ssh/id_rsa): enter
Enter passphrase (empty for no passphrase): enter
Enter same passphrase again: enter
Your identification has been saved in/home/oracle/.ssh/id_rsa.
Your public key has been saved in/home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
64:a6:4a:77:db:33:a4:aa:6e:ca:8f:5f:2f:77:0f:40oracle@node1
node1生成密钥dsa类型
id_dsa为私钥，自动保存到.ssh下
id_dsa.pub为公钥，自动保存到.ssh下
[grid@node1 ~]$ ssh-keygen-t dsa
Generating public/private dsa key pair.
Enter file in which to save the key(/home/oracle/.ssh/id_dsa): enter
Enter passphrase (empty for no passphrase): enter
Enter same passphrase again: enter
Your identification has been saved in/home/oracle/.ssh/id_dsa.
Your public key has been saved in/home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
7c:41:b5:0f:81:06:ad:30:07:4f:8b:1a:9b:94:68:14oracle@node1
node2生成密钥rsa类型
id_rsa为私钥，自动保存到.ssh下
id_rsa.pub为公钥，自动保存到.ssh下
[root@node2 ~]# su – grid
[grid@node2 ~]$ mkdir .ssh
[grid@node2 ~]$ ssh-keygen-t rsa
Generating public/private rsa key pair.
Enter file in which to save the key(/home/oracle/.ssh/id_rsa): enter
Enter passphrase (empty for no passphrase): enter
Enter same passphrase again: enter
Your identification has been saved in/home/oracle/.ssh/id_rsa.
Your public key has been saved in/home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
64:a6:4a:77:db:33:a4:aa:6e:ca:8f:5f:2f:77:0f:40oracle@node1
node2生成密钥dsa类型
id_dsa为私钥，自动保存到.ssh下
