安装环境:

操作系统:oracle linux 4.8 64位

集群软件:10201_clusterware_linux_x86_64.cpio.gz

数据库:10201_database_linux_x86_64.cpio.gz

cpu:1颗

内存:必须1.5G以上(一般是2G)

本地磁盘:20G(根分区17G,swap是4G,boot分区是512M)

asm下载地址:http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel4-092650.html#oracleasm_rhel4_amd64

asm软件:oracleasm-support-2.1.7-1.el4.x86_64.rpm 

               oracleasmlib-2.0.4-1.el4.x86_64.rpm

               oracleasm-2.6.9-89.35.1.EL-2.0.5-1.el4.x86_64.rpm

IP地址划分:192.168.3.30   rac10g01      eth0

       192.168.3.40   rac10g01      eth0

       192.168.3.50   rac10g01-vip    eth0:1

       192.168.3.60   rac10g02-vip    eth0:1

       10.0.0.1      rac10g01-priv   eth1

       10.0.0.2      rac10g02-priv   eth1

IP说明:

      每台服务器必须两块网卡, public ip和priv ip不能在同一网段.public和priv必须在网卡中写明地址,vip在地址是数据库自己添加的.

1.安装操作系统,图形化安装

    安装系统时将iptable和selinux全部禁用

2.配置虚拟机的网卡
