13 建立和测试用户等效性
仅在一个节点上执行
exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add
例如
[oracle@inthrac01 ~]$ exec /usr/bin/ssh-agent $SHELL
[oracle@inthrac01 ~]$ /usr/bin/ssh-add
Enter passphrase for /home/oracle/.ssh/id_rsa:
Identity added: /home/oracle/.ssh/id_rsa (/home/oracle/.ssh/id_rsa)
Identity added: /home/oracle/.ssh/id_dsa (/home/oracle/.ssh/id_dsa)
测试
[oracle@inthrac01 ~]$ ssh oracle@inthrac02 date
Wed Jan 27 01:07:58 CST 2010
如果前面没有输入过密码的话，这里会提示输入密码一次。以后就不会叻
14 安装CRS
加入CRS的环境变量
建立CRS目录
export ORACLE_BASE=/u01/app/oracle
export CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
mkdir $ORACLE_BASE/product/10.2.0/crs_1 -p
从Oracle网站下载10201_clusterware_linux32.zip
15. 安装ASM和Raw device
asm的安装这里不做介绍叻
ASM在10g的CRS里是不能存ocr和vote disk，所以我们这里可用ocfs/ocfs2和raw device来存ocr和vote disk
这里介绍raw device的方法。
这里我是用NAS的方式做的共享存储。
共享设备是/dev/sdd /dev/sde
其中
/dev/sdd 400M
/dev/sde 600M
/dev/sdd 给vote disk /dev/sde给ocr
在每个节点上修改/etc/sysconfig/rawservices
/dev/raw/raw1 /dev/sde1
/dev/raw/raw2 /dev/sdd1
执行
service rawdevices start
chown root:oinstall /dev/raw/raw[12]
chmod 660 /dev/raw/raw[12]
一切就绪，下面就开始安装叻
以Oracle用户登录一个节点，或者用客户端图形软件，我一般使用nx
unzip -x 10201_clusterware_linux32.zip
执行上面提到的建立用户等效性
exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add
保险起见，你可以先运行安装包里的cluvfy来检验一下安装
cluvfy/runcluvfy.sh stage -pre crsinst -n inthrac01
cluvfy/runcluvfy.sh stage -pre crsinst -n inthrac02
如果有时在节点上等效性验证失败的话，你可以执行一下ssh oracle@inthrac01 date，比如我在节点1上等效性验证失败，执行ssh oracle@inthrac01 dat，第一次输入密码，再执行一次，如果不需要密码，在检验一次，就可以通过叻。
安装crs软件
安装完成，根据提示，分别在两个节点执行$ORACLE_BASE/oraInventor/orainstRoot.sh
都执行完以后，再分别在两个节点执行$CRS_HOME/root.sh
执行结果如下
WARNING: directory '/u01/app/oracle/product/10.2.0' is not owned by root

Waiting for the Oracle CRSD and EVMD to start

我们现在执行crsctl check crs看看crs的状况
[oracle@inthrac01 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
CRS已经安装成功了。
下面用crs_stat -t看看我们的crs里的应用
[oracle@inthrac02 ~]$ crs_stat -t
CRS-0202: No resources are registered.
这里提示是没有资源注册，为什么了。你可以注意到我们在上面root.sh的结果看到
在最后执行的节点上，会出现
The given interface(s), "eth0" is not public. Public interfaces should be used to configure virtual IPs.
vip配置失败，而vip的资源应用时所有的基础，这个有问题，其他的也都没有registery进来，解决方法在其中一个节点上以root执行vipca，手工配置vip。
[oracle@inthrac01 ~]$vipca
安装结束我们在看看这些resouce的状态
[oracle@inthrac01 ~]$ crs_stat -t
