系统环境：
操作系统：RedHat EL5（64）
Oracle 软件：Oracle 11gR2、Oracle GI
对于Oracle 11g使用ASM作为存储系统，必须要构建Oracle GI的环境。
安装Oracle GI:
1、以grid用户的身份登录系统安装
开始安装
安装注意选择standalone server
建立磁盘组
确认用户组
确认安装目录（由于/u01下空间，不足，后改为/dsk1下）
安装
以root用户，执行root.sh脚本
[root@bjsrv ~]#/dsk1/11.2.0/grid/root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= grid
ORACLE_HOME= /dsk1/11.2.0/grid
Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: y
Copying dbhome to /usr/local/bin ...
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: y
Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: y
Copying coraenv to /usr/local/bin ...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.

如果，大家在Oracle 11g构建过RAC，可以看出这个root.sh和在RAC下略有不同
安装完成
