DNS主从服务

DNS主从服务

• 实验环境:在上一个实验基础上（主服务器）

步骤

修改主服务器中区域信息文件

vim /etc/named.rfc1912.zones
zone "linuxprobe.com" IN {
        type master;
        file "linuxprobe.com.zone";
        allow-update {192.168.18.19;};
};
zone "18.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.18.arpa";
        allow-update {192.168.18.19;};
};

systemctl restart named

修改主服务器中区域信息文件

安装服务

yum -y install bind*
systemctl restart named
systemctl enable named

修改主配置文件

vim /etc/named.conf
options {
        listen-on port 53 { any; };   #监听的端口的ip(ip可多个，any表示所有)
        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; };   #允许dns查询的客户机列表any表示所有

修改区域配置文件

vim /etc/named.rfc1912.zones
zone "linuxprobe.com" IN {
        type slave;
        masters{192.168.18.10;};
        file "slaves/linuxprobe.com.zone";
};
zone "18.168.192.in-addr.arpa" IN {
        type slave;
        masters{192.168.18.10;};
        file "slaves/192.168.18.arpa";
};

systemctl restart named

验证

cd /var/named
ls slaves/
192.168.18.arpa  linuxprobe.com.zone

vim /etc/resolv.conf
nameserver 192.168.18.19

nslookup
