CentOS6.4下安装Oracle11G集群

前提：使用图形化完成ssh配置，如下图：

错误现象：

安装grid软件时报错INS-41112错误，如下图所示：

两节点进行ping测试，分别ping“公有IP”和“私有IP”，两节点ping通正常后，按如下方式配置：

1、两节点进行SSH验证

节点1：

[grid@test1 ~]$ 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.

[grid@test1 ~]$ ssh rac2priv date

Wed Oct 29 17:04:14 CST 2014

[grid@test1 ~]$ ssh rac1priv date

--验证节点1私有IP

The authenticity of host ‘rac1priv (192.168.56.72)‘ can‘t be established.

RSA key fingerprint is 48:3b:19:c1:d6:5d:fb:9e:32:09:3a:82:4f:2e:ad:81.

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

Warning: Permanently added ‘rac1priv,192.168.56.72‘ (RSA) to the list of known hosts.

[grid@test1 ~]$ ssh rac1priv date

Wed Oct 29 16:40:48 CST 2014

[grid@test2 ~]$ ssh test1 date

--验证节点1公有IP

Wed Oct 29 17:04:14 CST 2014

[grid@test2 ~]$ ssh test2 date

--验证节点2公有IP

Wed Oct 29 17:04:14 CST 2014

节点2：

[grid@test2 ~]$ ssh rac1priv date

The authenticity of host ‘rac1priv (192.168.56.72)‘ can‘t be established.

RSA key fingerprint is 48:3b:19:c1:d6:5d:fb:9e:32:09:3a:82:4f:2e:ad:81.

[grid@test2 ~]$ ssh rac1priv date

Wed Oct 29 16:42:01 CST 2014

[grid@test2 ~]$ ssh rac2priv date

The authenticity of host ‘rac2priv (192.168.56.73)‘ can‘t be established.

[grid@test2 ~]$ ssh rac2priv date

Wed Oct 29 17:05:48 CST 2014

[grid@test2 ~]$ ssh rac1priv date

Wed Oct 29 16:46:32 CST 2014

[grid@test2 ~]$ ssh test1 date

--验证节点1公有IP

Wed Oct 29 16:46:48 CST 2014

[grid@test2 ~]$ ssh test2 date

--验证节点2公有IP

2、在两个节点上关闭不必要的服务

节点1：

[root@test1 /]# chkconfig NetworkManager off

[root@test1 /]# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config

[root@test1 /]# chkconfig iptables off

节点2：

[root@test2 ~]# chkconfig NetworkManager off

[root@test2 ~]# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config

[root@test2 ~]# chkconfig iptables off

重新执行grid安装，正常通过了。
