redhat5.5_11gR2_RAC_安装,这篇主要记录RAC安装的执行步骤，最烦琐的就是前期配置，到后面图形界面runInstaller,asmca,dbca就很容易了。
--hostname检查--
[root@node1 Server]# hostname
node1
--hostname修改，假定两个节点，node1,node2—
[root@node1 Server]#vi /etc/sysconfig/network
[root@node1 Server]#hostname xxx
--修改hosts文件，注意对应的hostname和命名，注意127那两列，不要出现主机名，每台机器需要两个网卡，一个绑定public-ip，一个绑定private-ip，virtual-ip和scan-ip会在安装完grid后自动开通--
[root@node1 Server]# cat /etc/hosts
# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 #public ip 192.168.100.101 node1 192.168.100.102 node2 #virtual ip 192.168.100.201 node1-vip 192.168.100.202 node2-vip #private ip 10.10.10.1 node1-priv 10.10.10.2 node2-priv #scan ip 192.168.100.250 racscan
--创建grid(管理grid)和oracle(管理database)用户，以及oinstall、dba、oper、asmadmin、asmoper、asmdba组—

--在两个节点安装cvuqdisk包并验证--
在两个 Oracle RAC 节点上安装操作系统程序包 cvuqdisk。
如果没有 cvuqdisk，集群验证实用程序就无法发现共享磁盘，当运行（手动运行或在 Oracle Grid Infrastructure 安装结束时自动运行）集群验证实用程序时，会收到这样的错误消息：“Package cvuqdisk not installed”。使用适用于硬件体系结构（例如，x86_64 或 i386）的 cvuqdisk RPM。
cvuqdisk RPM 包含在 Oracle Grid Infrastructure 安装介质上的 rpm 目录中。
设置环境变量 CVUQDISK_GRP，使其指向作为 cvuqdisk 的所有者所在的组（本文为 oinstall）：
[root@node1 rpm]# pwd
/oracle-tools/oracle11gR2_linux/grid/rpm
[root@node1 rpm]# ll

--安装前检查，最后会因为dns过不去，可以忽略。最后就是图形界面安装，先用grid用户安装grid，再用oracle用户安装db，之后用grid用户设置asm，最后oracle用户dbca建立数据库--
