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

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

代码31

[root@sgdb1 ~]# /oracle/oraInventory/orainstRoot.sh
