oracle linux 4.8安装oracle 10g rac环境之cluster安装
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
