系统环境：
操作系统：RedHat EL5
Cluster： Oracle GI(Grid Infrastructure)
Oracle： Oracle 11.2.0.1.0
如图所示：RAC 系统架构
三、安装GI之前，可以以grid用户的身份对环境进行检测。
以grid 用户的身份校验安装环境（在grid的安装软件包目录下）

grid]$ ./runcluvfy.sh stage -pre crsinst -n node1,node2 -fixup -verbose
---在检测中会提示，“failed”的位置，需要fixup.

、需要安装的软件包（all nodes）
配置yum安装环境：
[root
@node1
yum.repos.d]# cp rhel-debuginfo.repo yum.repo
[root
@node1
yum.repos.d]# ls
rhel-debuginfo.repo yum.repo
[root
@node1
yum.repos.d]# cat yum.repo
[Base]

baseurl=file:
///media/Server
enabled=

gpgcheck=

gpgkey=file:
///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
挂载linux ISO 光盘：
[root
@node1
yum.repos.d]#mount /dev/hdc /media

、配置用户之间的信任关系（oracle和grid）
建立节点之间oracle 、grid 用户之间的信任（通过ssh 建立公钥和私钥）
=====Oracle==========

）生成密钥对（all nodes）
[oracle
@node1
~]$ ssh-keygen -t rsa
Generating

rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Enter passphrase (empty

no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your
public
