ORACLE RAC用DNS服务器的配置

news 2024/11/7 11:40:32

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

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;
        };
};

        type hint;
        file "named.ca";
        //file "/dev/null";
};
 
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

vim /etc/named.rfc1912.zones,

//

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

        type master;
        file "16.168.192.local";
