[terry笔记]redhat5.5_11gR2_RAC_安装
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
:: 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—
--如果只创建一个oracle用户我试验也可以，但是会造成一定的混乱，因为grid和database两个的软件的目录中，存在相同的命令--
[root@node1 Server]#groupadd -g 1000 oinstall
[root@node1 Server]#groupadd -g 1001 dba
[root@node1 Server]#groupadd -g 1002 oper
[root@node1 Server]#groupadd -g 1003 asmadmin
[root@node1 Server]#groupadd -g 1004 asmoper
[root@node1 Server]#groupadd -g 1001 asmdba
[root@node1 Server]#useradd –u 1000 –g oinstall –G dba,asmdba,oper oracle
[root@node1 Server]#passwd oracle
[root@node1 Server]#useradd –u 1001 –g oinstall –G dba,asmadmin,asmoper,asmdba,oper grid
[root@node1 Server]#passwd grid
[oracle@node6 ~]$ id
uid=1000(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1002(oper),1005(asmdba)

--创建相关目录--
[root@node1 Server]# mkdir -p /u01/ora11g/oracle
[root@node1 Server]# mkdir -p /u01/ora11g/grid
[root@node1 Server]# mkdir -p /opt/ora11g

[root@node1 Server]# chown -R grid:oinstall /opt/ora11g
[root@node1 Server]# chmod 777 /u01
--关闭系统ntp服务（同步时间），11gR2自带同步时间的服务，移除ntp服务的配置文件，不然GRID还是会找ntp--
[root@node1 /]# service ntpd stop
[root@node1 /]# chkconfig ntpd off
[root@node1 /]# chkconfig sendmail off
[root@node1 /]# mv /etc/ntp.conf /etc/ntp.conf.bk

--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
