在rac2执行脚本

这里出现了一个错误

根据提示查看日志

[grid@rac1 grid]$ vi /u01/app/oraInventory/logs/installActions2016-04-10_04-57-29PM.log

由错误日志可知，是因为没有配置resolve.conf，可以忽略

安装完成

安装grid清单位置

至此grid集群软件安装完成

2.安装grid后的资源检查

以grid用户执行以下命令。
[root@rac1 ~]# su - grid

检查crs状态

[grid@rac1 ~]$ crsctl check crsCRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online12345

检查Clusterware资源

[grid@rac1 ~]$ crs_stat -t -v

检查集群节点

[grid@rac1 ~]$ olsnodes -n
rac1    1rac2    2123

检查两个节点上的Oracle TNS监听器进程

[grid@rac1 ~]$ ps -ef|grep lsnr|grep -v 'grep'|grep -v 'ocfs'|awk '{print$9}'LISTENER_SCAN1
LISTENER123

确认针对Oracle Clusterware文件的Oracle ASM功能：
如果在 Oracle ASM 上暗转过了OCR和表决磁盘文件，则以Grid Infrastructure 安装所有者的身份，使用给下面的命令语法来确认当前正在运行已安装的Oracle ASM:

[grid@rac1 ~]$ srvctl status asm -a
ASM is running on rac2,rac1
ASM is enabled.123

3.为数据和快速恢复去创建ASM磁盘组

官方文档中规定了不同冗余策略下OCR、Voting disk、Database和Recovery所需的大小

只在节点rac1执行即可
进入grid用户下
[root@rac1 ~]# su - grid
利用asmca
[grid@rac1 ~]$ asmca

这里看到安装grid时配置的OCR盘已存在

添加DATA盘，点击create，使用裸盘raw4

同样创建FRA盘，使用裸盘raw5

ASM磁盘组情况
