第8步：安装Oracle

1. 1. 安装Oracle

注意，安装Oracle时需要以oracle用户身份执行，在那之前需要以root身份执行xhost+，即命令：

代码1

[root@sgdb1~]# xhost+

[root@sgdb1~]# su - oracle

图1  执行xhost+

[oracle @sgdb1~]$ cd database

[oracle @sgdb1~]$ ./runinstaller

图2       执行runInstaller

1. 1. 1. 取消软件更新

4. 4. 4. Oracle安装方式

点击【Oracle Real Application Clusters Database Installation】，选择RAC方式安装，并将两个节点勾选。

安装到最后阶段，需要在两节点（SGDB1与SGDB2）上分别以root身份执行这个脚本：

图46       安装结束前需要执行的脚本
