ORACLE RAC用DNS服务器的配置

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

[root@oracle ~]# vi /etc/named.conf

//

// named.conf

//

// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS

// server as a caching only nameserver (as a localhost DNS resolver only).

//

// See /usr/share/doc/bind*/sample/ for example named configuration files.

//

options {

listen-on port 53 { any; }; #默认监听IP是127.0.0.1，any或者注释掉就是允许所有IP

listen-on-v6 port 53 { any; }; #ip6监听地址

directory "/var/named"; #存放区域配置文件的目录

dump-file "/var/named/data/cache_dump.db";

statistics-file "/var/named/data/named_stats.txt";

memstatistics-file "/var/named/data/named_mem_stats.txt";

allow-query { any; }; #只允许本地主机localhost，any或者注释掉就是允许所有主机查询

recursion yes; #是否开启迭代查询功能

dnssec-enable yes;

dnssec-validation yes;

/* Path to ISC DLV key */

bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";

};

logging {

channel default_debug {

file "data/named.run";

severity dynamic;

};

};

zone "." IN {

type hint;

file "named.ca";

//file "/dev/null";

};

include "/etc/named.rfc1912.zones";

include "/etc/named.root.key";

vim /etc/named.rfc1912.zones,

// named.rfc1912.zones:

//

// Provided by Red Hat caching-nameserver package

//

// ISC BIND named zone configuration for zones recommended by

// RFC 1912 section 4.1 : localhost TLDs and address zones

// (c)2007 R W Franks

//

// See /usr/share/doc/bind*/sample/ for example named configuration files.

//

//配置正向解析Zone

zone "ntt.com" IN {

type master;

file "ntt.com.zone";

allow-update { none; };

};

//注意，这个域名要和后面配置的一致

//配置反向解析Zone

zone "16.168.192.in-addr.arpa" IN {

type master;

file "16.168.192.local";

allow-update { none; };

};
