Linux平台 Oracle 11gR2 RAC安装指导：

Part1：Linux平台 Oracle 11gR2 RAC安装Part1：准备工作

Part2：Linux平台 Oracle 11gR2 RAC安装Part2：GI安装

Part3：Linux平台 Oracle 11gR2 RAC安装Part3：DB安装

三、GI(Grid Infrastructure)安装

3.1 解压GI的安装包

首先grid用户登录，创建解压介质的目录：

mkdir -p /opt/app/media && chmod 777 /opt/app/media && cd /opt/app/media

然后unzip解压安装GI的安装介质

p13390677_112040_Linux-x86-64_3of7.zip

到/opt/app/media这个目录下：

unzip p13390677_112040_Linux-x86-64_3of7.zip -d /opt/app/media

3.2 安装配置Xmanager软件

在自己的Windows系统上成功安装Xmanager Enterprise之后，运行Xstart.exe可执行程序，

配置如下

Session：RAC1
Host：172.16.7.112
Protocol：SSH
User Name：grid
Execution Command：/usr/bin/xterm -ls -display $DISPLAY

点击RUN，输入grid用户的密码可以正常弹出命令窗口界面，即配置成功。

3.3 共享存储LUN的赋权

chown grid:asmadmin /dev/mapper/mpath*

这个重启验证过，multipath对应的原始设备/dev/dm-*的权限重启后会变更为root:disk，而我们需要的权限是grid:asmadmin

chown grid:asmadmin /dev/mapper/mpath*

将这个加入开机启动脚本/etc/rc.local中。

3.4 使用Xmanager图形化界面安装GI

Xmanager通过grid用户登录，进入介质解压目录，运行runInstaller安装GI

$ cd /opt/app/media/grid/
$ ls
install  readme.html  response  rpm  runcluvfy.sh  runInstaller  sshsetup  stage  welcome.html
$ ./runInstaller

我这里设定ASM密码：orclasm

创建SYSDG作为OCR和Voting Disk的ASM磁盘组（3个10G的LUN，冗余级别：normal）

安装过程中可忽略的检查项（如果你的检查项中还有其他的，则不可以忽略）:

Package：pdksh-5.2.14         //这个RHEL中光盘中没有pdksh这个包，之前准备工作中已安装ksh代替
Package:cvuqdisk-1.0.9-1      //这个可以按提示手工修复，也可以忽略安装后自动修复
Device Checks for ASM
Network Time Protocol(NTP)
Task resolv.conf Integrity

root用户执行2个脚本，需要在各节点分别执行

节点1执行两个脚本的屏幕输出如下：

[root@jyracdb1 ~]# /opt/app/oraInventory/orainstRoot.sh
Changing permissions of /opt/app/oraInventory.
