Linux平台 Oracle 11gR2 RAC安装指导：
Part1： Part2： Part3：三、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：RAC1Host：172.16.7.112Protocol：SSHUser 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/$ lsinstall 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.shChanging permissions of /opt/app/oraInventory.Adding read,write permissions for group.Removing read,write,execute permissions for world.Changing groupname of /opt/app/oraInventory to oinstall.The execution of the script is complete.[root@jyracdb1 ~]# /opt/app/11.2.0/grid/root.shPerforming root user operation for Oracle 11g The following environment variables are set as: ORACLE_OWNER= grid ORACLE_HOME= /opt/app/11.2.0/gridEnter the full pathname of the local bin directory: [/usr/local/bin]: The contents of "dbhome" have not changed.

节点2执行两个脚本的屏幕输出如下：
