开始测试oracle 11g rac，本本的性能有限，因此装个单节点rac。步骤如下：
网卡绑定
修改/etc/modprobe.conf 和/etc/sysconfig/network-scripts下的ifcfg-bond* ifcfg-eth*
这里不再多说
配置Xmanager连接
vi /usr/share/gdm/defaults.conf
将[xdmcp]下的Enable=false 改成 Enable=true
AllowRemoteRoot=false 改成 AllowRemoteRoot=true
使之生效：
gdm-restart

安装cvuqdisk包
在grid安装目录中的rpm下，安装这个包
[root@rac rpm]# rpm -ivh cvuqdisk-1.0.9-1.rpm
Preparing... ########################################### [100%]
Using default group oinstall to installpackage
1:cvuqdisk ###########################################[100%]
若cvuqdisk的所有者不为oinstall，则需要设置环境变量CVUQDISK_GRP的值为该用户组
安装Grid Infrastructure
使用grid用户登录，执行runInstaller来安装
这里的cluster name 添集群名称，scan name填上在dns服务器中配置的scan ip对应的名称
创建asm disk group，用于存放ocr和vote，冗余度normal为3倍，high为5倍
