作者: ZHQIAN | 来源:发表于2017-10-05 09:03 被阅读38次

    配置文件 /etc/named.conf
    日志文件 /var/log/messages
    准备两台虚拟机(server (IP 192.168.56.2) , client (IP 192.168.56.3))

    在server上安装DNS服务
    关闭防火墙

    #systemctl stop firewalld
    

    查看DNS是否安装

    #yum info named
    

    Step1:下载服务

    # yum install named bind bind-chroot bind-utils //正式安装
    

    Step2:配置named.conf文件

    # vi /etc/named.conf
    

    listen-on port 53 { 127.0.0.1; } //127.0.0.1;改成any;
    allow-query { localhost; } //localhost;改成any;
    在底部插入文本
    zone "mysite.com" IN {
    type master;
    file "mysite.com.zone";
    allow-update { none; };
    };
    Step3:增加自定义域名解析文件及反向解析

    # cd /var/named
    

    Step4:拷贝服务到域名

    #cp  /usr/share/doc/bind-9.9.4/sample/var/named/named.localhost\
      ./mysite.com.zone 
    

    Step5:添加A数据

    #vi mysite.com.zone
    

    www<Tab>IN A<Tab>192.168.1.100
    Step6:配置服务

    #systemctl start named  
    

    Step7:在client上配置resolv.conf

    #vi /etc/resolv.conf
    

    nameserver 192.168.56.2 //nameserver 221.228.255.1前加“#”
    Step8:测试DNS服务

    #ping www.mysite.com
    

    PING www.mysite.com (192.168.1.100) 56(84) bytes of data.
    From 10.20.1.1 icmp_seq=1 Time to live exceeded
    From 10.20.1.1 icmp_seq=2 Time to live exceeded
    From 10.20.1.1 icmp_seq=3 Time to live exceeded
