14：安装Oracle Clusterware

（1）解压软件包
这里假定数据库所有软件放在了/rac目录下，首先需要解压Oracle的两个软件包，操作如下：
[root@node-rac1 rac]#ls
linux_11gR1_database_1013.zip linux_x86_11gR1_clusterware.zip
[root@node-rac1 rac]#unzip linux_x86_11gR1_clusterware.zip
[root@node-rac1 rac]#unzip linux_11gR1_database_1013.zip
（2）安装补丁包
解压完成，安装补丁包
[root@node-rac1 rac]#/rac/clusterware/rpm
[root@node-rac1 rac]#rpm -Uvh cvuqdisk-1.0.1-1.rpm
在节点node-rac1安装完成后，继续在node-rac2进行补丁安装。
（3）验证安装环境
在开始安装之前，可以使用oracle自动的一个检测脚本验证系统环境是否可以进行安装，香港虚拟主机，以oracle身份登录系统，执行如下命令：
[oracle@node-rac1 ~]$/rac/clusterware/runcluvfy.sh stage -pre crsinst -n node-rac1,node-rac2 -verbose
（4）开始安装
以oracle用户登录Linux图形界面，然后执行安装脚本：
[oracle@node-rac1 ~]$ cd /rac/clusterware/
[oracle@node-rac1 clusterware]$ ./runInstaller
接着就会弹出图形安装向导界面，安装过程非常简单，美国空间，香港空间，这里仅仅给出安装图解，所有操作内容以截图为准，不做描述。

根据安装向导提示，以root用户身份在所有节点上分别执行上述两个脚本，要一个节点一个节点地执行，在node-rac1执行root.sh时的信息如下：
[root@node-rac1 crs]# ./root.sh
WARNING: directory '/app/oracrs/product/11.0.6' is not owned by root
WARNING: directory '/app/oracrs/product' is not owned by root
/etc/oracle does not exist. Creating it now.

node-rac1
Cluster Synchronization Services is inactive on these nodes.
node-rac2

继续在node-rac2执行root.sh脚本，输出如下：
[root@node-rac2 crs]# ./root.sh
WARNING: directory '/app/oracrs/product/11.0.6' is not owned by root
WARNING: directory '/app/oracrs/product' is not owned by root

最后，给出安装完成验证信息，显示如下：
