配置DNS服务器

1.安装DNS软件包

# 检查是否安装DNS服务相关软件包
rpm -qa|grep bind
yum clean all
# 如果没有安装，设置联网后yum安装bind包
yum -y install bind

2.修改配置文件

# 修改和创建三个配置文件：
# 1.全局配置文件/etc/named.conf
# 2.正向解析文件/var/named/hbliti.com.file
# 3.反向解析文件/var/named/192.168.100.file

#全局配置文件
[root@localhost ~]# vim /etc/named.conf
options {
#修改{}内容为any
    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";
    recursing-file  "/var/named/data/named.recursing";
    secroots-file   "/var/named/data/named.secroots";
#修改{}内容为any
    allow-query     { any; };
#该文件是named.conf包含的文件，属于named.conf。如修改此文件名，后面要跟着修改。
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";#同上
#如果named.conf中修改了文件名，这里跟着修改。
[root@localhost ~]# vim /etc/named.rfc1912.zones
#可以删除原有内容只增加正向解析
zone "hbliti.com" IN {
        type master;
        file "hbliti.com.file";
        allow-update { none; };
};
#增加反向解析
zone "100.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.100.file";
        allow-update { none; };
};

#启动时如果出现下面错误提示，检查三个配置文件编写内容的错误，改正后一般可解决。
[root@localhost etc]# systemctl start named.service
Job for named.service failed because the control process exited with error code. 
See "systemctl status named.service" and "journalctl -xe" for details.
#重启DNS服务
[root@localhost etc]# systemctl restart named.service

测试DNS服务

修改windows系统网卡的DNS地址为192.168.100.254，虚拟dos下运行nslookup命令即可进行测试
