VMware上安装Oracle 10g RAC-ASM+裸设备
操作系统版本RHEL5.5-64bit,oracle10g,vmware workstation6.5,clusterware10.0.2版本的,两台虚拟机双网卡,本地磁盘40G,共享
2.给虚拟机添加共享磁盘,首先在node1上面添加一块共享磁盘,选择分配全部的空间(虚拟机下一定要这么设置,否则会导致共享存储配置不成功)
node1添加共享磁盘(sharedisk.vmdk)-开机-关机,然后编辑node1的虚拟机配置文件,添加如下选项:
然后编辑node2的虚拟机配置文件,添加如下选项:
关闭虚拟机软件,,然后分别打开两台虚拟机的电源,共享磁盘配置完毕
3.oracle安装环境准备
这里参照我以前的文章,oracle安装前期准备工作的设置
在两个节点上面创建对应文件夹
这里oracle的变量设置做下更改
4.建立hangcheck模块加载(在两个节点上面操作)
5.配置两台机器无密码访问,这里的配置要在两个节点上面进行
(1)以oracle 用户登录
(2)在oracle 用户的主目录内创建.ssh 目录并设置正确的权限
完成后,在node1 上执行:
如果不需要输入密码就出现系统日期,说明SSH 配置成功。
6.磁盘规划
这里我把共享磁盘分成6个区,sdb1和sdb2配制成裸设备,作为OCR镜像,sdb5,6,7也配置成裸设备,作votedisk镜像,sdb配置成ASM用来存放数据库
配置裸设备
在node2上面执行 partprobe,然后同样建立裸设备
7.在两个节点上面安装,注意要下载和自己内核版本对应的包
在两个节点上面执行/etc/init.d/oracleasm configure
分别输入oracle,dba,y,y
在node1上面配置ASM
在node2上面执行扫描(不需要配置)
8.开启安装进程,在两个节点上面以root用户身份运行
然后切换到oracle用户,开始安装clusterware
1)选择CRS的安装目录
2)两个集群节点的配置
3)选择eth0网卡为公网IP
4)配置OCR存储位置
5)配置votedisk存储位置
6)安装
7)执行最后的安装脚本
在节点node1上面执行
在节点node2上面执行
在节点node1上面执行
在节点node2上面执行
安装结束,查看节点状态
