在REDHAT中，需要安装一些包：
compat,gcc
删除已经安装过的CRS：
1.删除/etc/oracle和/etc/orainst（oratab）文件，删除CRShome中的文件
2。裸设备的建立：/etc/udev/rules.d/60-raw.rules里面添加
ACTION=="add",KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add",KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add",KERNEL=="sdb3",RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add",KERNEL=="sdb4",RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add",KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add",KERNEL=="sdc2",RUN+="/bin/raw /dev/raw/raw6 %N"
#ACTION=="add",KERNEL=="/dev/sdc3",RUN+="raw /dev/raw/raw7 %N"
ACTION=="add",KERNEL=="raw[1-6]",OWNER="oracle",GROUP="oinstall",MODE="600"
重启服务：start_udev
ls -lrt /dev/raw/
