CentOS6.4下安装Oracle11G集群
前提：使用图形化完毕ssh配置，例如以下图：
错误现象：
安装grid软件时报错INS-41112错误，例如以下图所看到的：
两节点进行ping測试。分别ping“公有IP”和“私有IP”，两节点ping通正常后，按例如以下方式配置：
1、两节点进行SSH验证
节点1：
[[email protected] ~]$ ssh rac2priv date
--验证节点2私有IP
The authenticity of host ‘rac2priv (192.168.56.73)‘ can‘t be established.
RSA key fingerprint is a3:ab:da:a3:f1:0a:40:02:97:0c:96:2b:ad:43:60:b7.
Are you sure you want to continue connecting (yes/no)?
yes
Warning: Permanently added ‘rac2priv,192.168.56.73‘ (RSA) to the list of known hosts.

Wed Oct 29 17:04:14 CST 2014
[[email protected] ~]$ ssh rac1priv date
--验证节点1私有IP

[[email protected] ~]$ ssh rac1priv date
Wed Oct 29 16:40:48 CST 2014
[[email protected] ~]$ ssh test1 date
--验证节点1公有IP
Wed Oct 29 17:04:14 CST 2014
[[email protected] ~]$ ssh test2 date
--验证节点2公有IP
Wed Oct 29 17:04:14 CST 2014

[[email protected] ~]$ ssh test1 date
--验证节点1公有IP

2、在两个节点上关闭不必要的服务
节点1：
[[email protected] /]# chkconfig NetworkManager off
[[email protected] /]# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config
[[email protected] /]# chkconfig iptables off
节点2：
[[email protected] ~]# chkconfig NetworkManager off
[[email protected] ~]# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config
[[email protected] ~]# chkconfig iptables off
又一次运行grid安装，正常通过了。
