基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境:3.安装Oracle RAC-3.4.安装Grid Infrastructure
3.4.安装Grid Infrastructure
3.4.1.安装Grid
|
1.运行 grid的安装文件runInstaller |

安装图 略
以root用户按顺序执行
1.[root@rac1 ~]# /u01/app/oraInventory/orainstRoot.sh
2.[root@rac2 ~]# /u01/app/oraInventory/orainstRoot.sh
3.[root@rac1 ~]# /u01/app/11.2.0/grid/root.sh
4.[root@rac2 ~]# /u01/app/11.2.0/grid/root.sh 运行完脚本后,点击ok完成安装.如果不能rac-scan,那么会报错
