ORACLE RAC用DNS服务器的配置

荒川之神2024-11-11 18:42

一、搭建本地YUM源

二、安装DNS全部组建

yum -y install bind*

三、规划您RAC集群所有IP

#public

192.168.16.111 rac1.ntt.com rac1

192.168.16.112 rac2.ntt.com rac2

192.168.16.121 rac3.ntt.com rac3

192.168.16.122 rac4.ntt.com rac4

#private

10.10.10.111 rac1-priv.ntt.com rac1-priv

10.10.10.112 rac2-priv.ntt.com rac2-priv

10.10.10.121 rac3-priv.ntt.com rac3-priv

10.10.10.122 rac4-priv.ntt.com rac4-priv

#vip

192.168.16.113 rac1-vip.ntt.com rac1-vip

192.168.16.114 rac2-vip.ntt.com rac2-vip

192.168.16.123 rac3-vip.ntt.com rac3-vip

192.168.16.124 rac4-vip.ntt.com rac4-vip

#scan

192.168.16.115 rac11-scan.ntt.com rac11-scan

192.168.16.116 rac11-scan.ntt.com rac11-scan

192.168.16.117 rac11-scan.ntt.com rac11-scan

192.168.16.125 rac12-scan.ntt.com rac12-scan

192.168.16.126 rac12-scan.ntt.com rac12-scan

192.168.16.127 rac12-scan.ntt.com rac12-scan

#storge

192.168.16.188 storge.ntt.com storge

#database

192.168.16.100 hadoop.ntt.com hadoop

四、DNS配置文件
