Oracle 11gR2构建RAC之（5）–安装Oracle并建库
系统环境：
操作系统：RedHat EL5
Cluster： Oracle GI(Grid Infrastructure)
Oracle： Oracle 11.2.0.1.0
如图所示：RAC 系统架构
五、安装Oracle并建库
以oracle用户登录系统并安装Oracle软件和建立数据库
只安装软件，然后再建库
安装在RAC环境
安装软件
按照提示运行脚本（all nodes）
[root@node1 ~]# /u01/app/oracle/product/11.2.0/db_1/root.sh
Running Oracle 11g root.sh script... The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /u01/app/oracle/product/11.2.0/db_1 Enter the full pathname of the local bin directory: [/usr/local/bin]: 脚本运行成功后，即可完成Oracle的安装！
以grid运行asmca工具建立磁盘组：
建立dg1磁盘组用于存储database
建立dg1 磁盘组成功
创建rcy1 diskgroup用于存储recovery area
@至此，ASM磁盘组创建成功！
以oracle用户通过dbca建库：
建立RAC下的database
注意建立在所有node上
选择ASM存储，并通过OMF方式管理datafile
开始建库
建库完成后，即完成了Oracle 11g RAC的架构
验证：

@至此，整个Oracle 11g RAC的部署和架构全部完成！
