DNS服务器配置

此博文仅供学习之用，若文中有不足之处，请大家指正

例如我是搭建在集群上

master.chmei.com 192.168.0.50

slave1.chmei.com 192.168.0.51

slave2.chmei.com 192.168.0.52

slave3.chmei.com 192.168.0.53

slave4.chmei.com 192.168.0.54

做好虚拟机的初始化，保证网络可用

在主服务器(192.168.2.50)[我这里随机选一台机子做主服务器，我这里只是做个例子，也可建在这五台虚拟机以外的机子上]：

yum -y install bind-libs bind-utils bind

cd /etc/

mv named.conf named.conf.backup

vim named.conf

options {

        listen-on port 53 { any; };

        listen-on-v6 port 53 { ::1; };

        directory       "/var/named";

        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; };

        allow-recursion { 192.168.0.1/24; };

notify yes;

};

zone "." IN {

        type hint;

        file "named.ca";

};

zone "0.0.127.in-addr.arpa" IN {

        type master;

        file "named.loopback";

allow-transfer { none; };

};

zone "gzcd.com" IN {

        type master;

        file "chmei.com.zone";

allow-transfer { any; };

};

zone "0.168.192.in-addr.arpa" IN {

        type master;

        file "192.168.0.zone";

allow-transfer { any; };

};

chmod 640 named.conf

chown root:named named.conf

cd /var/named/

vim chmei.com.zone

chmod 640 192.168.0.zone

chown root:named 192.168.0.zone

vim /etc/resolv.conf

nameserver 192.168.0.50

nameserver 192.168.0.1

四台从服务器

yum -y install bind-libs bind-utils bind

cd /etc/

mv named.conf named.conf.backup

vim named.conf

options {

        listen-on port 53 { any; };

        listen-on-v6 port 53 { ::1; };

        directory       "/var/named";

        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; };

        recursion yes;

};

zone "." IN {

        type hint;

        file "named.ca";

};

zone "0.0.127.in-addr.arpa" IN {

        type master;

        file "named.loopback";

};

zone "chmei.com" IN {

        type slave;

        file "slaves/chmei.com.zone";

masters { 192.168.0.50; };

};

zone "0.168.192.in-addr.arpa" IN {

        type slave;

        file "slaves/192.168.0.zone";

masters { 192.168.0.50; };

};

chmod 640 /etc/named.conf

chown root:named /etc/named.conf

vim /etc/resolv.conf

nameserver 192.168.0.51

nameserver 192.168.0.1

最后检查三台服务器的时间是否一致，防火墙是否允许互为通信，SELINUX最好处于关闭状态，最后三台服务器都启动named服务：service named start

chkconfig named on

chkconfig --list

使用host master.chmei.com   host slave1.chmei.com   host slave2.chmei.com等查看是否能反向解析成功，

能成功解析出IP地址即为配置成功。

关闭SELINUX：

setenforce 0       临时关闭，重启PC后失效

sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/selinux/config    永久关闭

若不会设置防火墙，该PC也无机密，只是做练习之用，建议关闭防火墙：service iptables stop
