rac+CentOS48
RAC安装：
1.创建虚拟机，创建目录rac1,rac2 ,sharedstorage用于放磁盘
创建rac1,创建虚拟机时磁盘15G，再增加一个网卡，
，创建第一块共享磁盘0.5G，ocr1.disk SCSI1:
0
创建第二块共享磁盘0.5G，ocr1.disk SCSI1:
1
创建第三块共享磁盘3G，ocr1.disk SCSI1:
2
创建第四块共享磁盘3G，ocr1.disk SCSI1:
3
创建第五块共享磁盘3G，ocr1.disk SCSI1:
4
创建第六块共享磁盘3G，ocr1.disk SCSI1:
5
2.安装linux
安装好linux后，退出光盘,安装VMtool,VM-vmtool,双击vmware包
两个网卡的IP：
172。

重新启动 init6
安装ORACLE之前，要安装RPM包
sysstat.............rpm包
rpm-qa|grepgcc
rpm-ivhopenmotif21-2.1.3.......rpm
vi/etc/hosts
增加以下信息：
#public
172.30.0.77 rac1
172.30.0.78 rac2
#private
172.30.1.77 rac1-rac1-priv

#Virtual
172.30.2.77 rac1- rac1-vip
172.30.2.79 rac2- rac2-vip
vi/etc/sysctl.conf
增加内核参数
kernel.shmall=2097152
kernel.shmmax=2147483648
kernel.shmmni=4096
#semaphores:
semmsl,semmns,semopm,semmni
kernel.sem=25032000100128
