mkdir -p /etc/udev/scripts
vi /etc/udev/scripts/iscsidev.sh
#!/bin/sh
# FILE:/etc/udev/scripts/iscsidev.sh
BUS=${1}
HOST=${BUS%%:*}
[ -e/sys/class/iscsi_host ] || exit 1
file="/sys/class/iscsi_host/host${HOST}/device/session*/iscsi_session*/

[grid@rac1:/u01]$cd /u01/app/grid/soft
[grid@rac1:/u01/soft]$rz
linuxx64_12201_grid_home
解压文件
unzip linuxx64_12201_grid_home.zip
删除压缩包节约空间
[grid@rac1:/u01/soft]$rm -rf linuxx64_12201_grid_home.zip
验证
./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup -verbose
如果报PRVE-0421 : No entry exists in /etc/fstab for mounting /dev/shm
可忽略掉
进行安装
./gridSetup.sh
如果磁盘状态为Member的话，执行重建
dd if=/dev/zero of=/dev/sdb bs=1024 count=2056
23、grid用户，rac1查看集群状态
cd /u01/soft/grid/bin
./crs_stat -t

创建DATA和FRA磁盘组
24、oracle用户，rac1安装Oracle数据库软件
mkdir -p /u01/app/soft/
cd /u01/app/soft/
rz
linuxx64_12201_database.zip
unzip linuxx64_12201_database.zip
rm -rf linuxx64_12201_database.zip
cd database/
./runInstaller
重建完成的图忘记截了（直接点完成就好了）
25、oracle用户，rac1安装数据库
