会列出很多内容，检测是否符合安装Clusterware的条件，其中需要单独安装一个compat_db的包，oracle-validated包不会装这个
另外会报几个其他compat包检测失败则不用理会，因为只是版本不对而已
如果还碰到其他的没有passed的内容，则需要处理，直到除以上几个错误之外全都pass为止
--开始安装
cd ./clusterware
./runInstall -ignoreSysPreReqs (参数可以忽略大小写，命令不允许)
运行OUI到最后，会要求分别在2个节点执行2个脚本，顺序为：脚本1：RAC1->RAC2 ->脚本2：RAC1->RAC2
前3个次执行都没有问题，到第4步，在节点2上执行root.sh的时候，会报错：
[root@rac2 bin]# /u01/oracle/10.2.0/crs_1/root.sh

需要耐心等待好几分钟（90s+600s），然后会出现一个报错，这是由于Oracle在10.2.0.1上的bug所致，解决办法是通过修改$ORA_CRS_HOME/bin下满的vipca和srvctl文件，分别在这2个文件的第124行和168行（注意，不是文件末尾，否则更改可能会无效）添加unset LD_ASSUME_KERNEL后保存退出，再重新再节点2执行root.sh
[root@rac2 bin]# /u01/oracle/10.2.0/crs_1/root.sh
WARNING: directory '/u01' is not owned by root
Checking to see if Oracle CRS stack is already configured
Oracle CRS stack is already configured and will be running under init(1M)
[root@rac2 bin]# ./crs_stat -t
CRS-0202: No resources are registered.
此时由于还没有配置vip，因此没有资源被注册，去任意节点运行vipca（前提是这个节点的vipca已修改过），如果报以下错误：
[oracle@rac1 bin]$ vipca
Error 0(Native: listNetInterfaces:[3])
[Error 0(Native: listNetInterfaces:[3])]
那么需要配置一下网卡：
[oracle@rac1 bin]$ ./oifcfg iflist
eth0 192.168.1.0
eth1 10.0.0.0
[oracle@rac1 bin]$ ./oifcfg getif
[oracle@rac1 bin]$ ./oifcfg setif -global eth0/192.168.1.0:public
[oracle@rac1 bin]$ ./oifcfg setif -global eth1/10.10.10.1:cluster_interconnect
[oracle@rac1 bin]$ ./oifcfg getif
eth0 192.168.1.0 global public
eth1 10.10.10.1 global cluster_interconnect
注意要有打开图形界面的权限，并用root用户去执行vipca，而不是oracle用户，否则会报权限不足
[oracle@rac1 bin]$ vipca
Insufficient privileges.
Insufficient privileges.
接着就会跳出vip配置助手的OUI界面，开始配置vip，输入vip的节点别名后会自动填补vip的IP地址（过程略）
运行完vipca后退出，再次执行crs_stat，就会发现资源都已经注册到crs了
[root@rac1 bin]# ./crs_stat -t
