基于Linux的Oracle 11g RAC安装(2)



二、安装CRS

节点名称为rac01, rac02, 安装前可使用命令检查系统安装环境:

$ ./runcluvfy.sh stage -pre crsinst -n rac01,rac02 -verbose

开始安装CRS

$ ./runInstaller

一些截图:

集群配置, 这里添加集群节点.

指定网卡接口类型 

OCR配置

 Voting Disk配置  安装完成, 需要在集群每个节点以root用户运行如下脚本:
/u01/app/oraInventory/orainstRoot.sh
/u01/app/11.1.0/crs/root.sh   运行完脚本点击OK完成CRS安装.

节点rac01运行脚本输出:

[root@rac01 oraInventory]# ./orainstRoot.sh

安装完成后集群状态检查

1. 可在任意时候通过cluvfy命令检查CRS激活和配置情况:

[oracle@rac01 bin]$ ./cluvfy comp crs -n rac01,rac02

Verifying CRS integrity

Checking CRS integrity…

Checking daemon liveness…
Liveness check passed for "CRS daemon".

Checking daemon liveness…
Liveness check passed for "CSS daemon".

Checking daemon liveness…
Liveness check passed for "EVM daemon".

Checking CRS health…
CRS health check passed.

CRS integrity check passed.

Verification of CRS integrity was successful.

结果显示集群各组件都在健康的运行.

 

2. crs_stat命令提供集群状态摘要

[oracle@rac01 bin]$ ./crs_stat -t
