简易搭建局域网内部dns服务器

现状

管理内部的局域网的机器过多,不想浪费精力在对IP的记忆上,为了更方便的管理和使用,需要搭建一台内部
局域网服务器。

准备两台最小化Centos 7 服务器,一台用来搭建dns服务器,一台用来测试dns;一台window 10 用来测试dns,机器IP如下:

  • dns 服务器 IP:192.168.122.254
  • linux 客户端IP:192.168.0.71
  • window 客户端IP:192.168.0.254

实现步骤

配置部署服务端

在需要搭建dns服务的centos 7机器上操作

yum -y install bind  bind-chroot bind-utils
# 主要文件目录解析
/etc/named.conf  #主配置文件
/etc/named.rfc1912.zones #拓展配置文件
/var/named/              #zone 配置文件目录
#需要修改的配置如下:
listen-on port 53 { any; };

vim /etc/named.conf
options {
    listen-on port 53 { any; };  #监听0.0.0.0 53端口,ipv4
    listen-on-v6 port 53 { ::1; }; #监听0.0.0.0 53端口,ipv6
    directory   "/var/named";     #zone 目录
    dump-file   "/var/named/data/cache_dump.db"; #服务器存放数据库文件的路径名
    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";
    allow-query     { any; }; #允许查询
    recursion yes; #运行迭代
    dnssec-enable yes; 
    dnssec-validation yes;

    /* Path to ISC DLV key */
    bindkeys-file "/etc/named.iscdlv.key";

    managed-keys-directory "/var/named/dynamic";

    pid-file "/run/named/named.pid";
    session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
    type hint;
    file "named.ca";
};

include "/etc/named.rfc1912.zones"; #扩展配置文件
include "/etc/named.root.key";
#修改拓展文件
#添加下面信息:
zone "szlz.com" IN {
        type master;
        file "szlz.com.zone";
};

vim /etc/named.rfc1912.zones
zone "szlz.com" IN {
        type master;
        file "szlz.com.zone";
};


zone "localhost.localdomain" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
};

zone "localhost" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
};

zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
        type master;
        file "named.loopback";
        allow-update { none; };
};

zone "1.0.0.127.in-addr.arpa" IN {
        type master;
        file "named.loopback";
        allow-update { none; };
};

zone "0.in-addr.arpa" IN {
        type master;
        file "named.empty";
        allow-update { none; };
};
#配置zone
cd /var/name/
#需要-a选项,保留权限,如果named没有权限,无法启动
cp -a  named.localhost  szlz.com.zone
vim szlz.com.zone 

$TTL 1D
@       IN SOA  @ dns.szlz.com. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum

#启动bind并开机自启动
systemctl start named
systemctl enable named

开启防火墙

systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld
iptables -A INPUT -p tcp --dport 53 -j ACCEPT

配置linux客户端

登录dns测试服务器

vim /etc/resolv.conf
nameserver 192.168.122.254
nameserver 114.114.114.114 

配置windows客户端
