节点1：
[root@xzxt1 ~]# chkconfig NetworkManager off
[root@xzxt1 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[root@xzxt1 ~]# chkconfig iptables off
节点2：
[root@xzxt2 ~]# chkconfig NetworkManager off
[root@xzxt2 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[root@xzxt2 ~]# chkconfig iptables off
重新启动server。
假设不进行手工grid检查，当图形化安装grid时也会报出对应错误。能够參考另外一篇文章。链接地址例如以下：
