CentOS7 搭建BIDN9 DNS服务器

2019/03/26 Linux

1.安装

1.1. 环境

系统版本: CentOS 7

软件版本: BIND 9.11

IP: 192.168.8.22

1.2. 安装

yum -y install bind

2. 配置

2.1. 修改全局配置文件

修改 /etc/named.conf

修改 listen-on port 53 { any; }; 将监听所有网卡

修改 allow-query { any; }; 接受所有地址请求

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";
        recursing-file  "/var/named/data/named.recursing";
        secroots-file   "/var/named/data/named.secroots";
        allow-query     { any; };

        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;

        bindkeys-file "/etc/named.root.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";
include "/etc/named.root.key";

2.2. 建立本地解析域名

  1. /etc/named.rfc1912.zones 文件中追加

     zone "test.com" IN {
         type master;
         file "test.com.zone";
         allow-update {none;};
     };
    	
     zone "8.168.192.in-addr.arpa" IN {
         type master;
         file "192.168.8.arpa";
         allow-update {none;};
     };
    
  2. 检查是否正确

    named-checkconf

  3. 建立区域文件

    正向解析

     $ cat > /var/named/test.com.zone<<EOF
     $TTL 1D
     @    IN 	SOA    test.com. rname.invalid. (
                                                 0    ; serial
                                                 1D    ; refresh
                                                 1H    ; retry
                                                 1W    ; expire
                                                 3H )    ; minimum
         NS      @
         A       127.0.0.1
         AAAA    ::1
     ns    IN    A    192.168.8.29
     harbor    IN    A    192.168.8.29
     EOF
    

    反向解析

     $ cat /var/named/192.168.8.arpa
     $TTL 1D
     @    IN SOA    test.com. rname.invalid. (
                         0    ; serial
                         1D    ; refresh
                         1H    ; retry
                         1W    ; expire
                         3H )    ; minimum
         IN    NS    @
         A    127.0.0.1
         AAAA    ::1
         PTR    localhost.
     ns    IN    A    192.168.8.29
     244    IN    PTR    ns.test.com
     250    IN    PTR    harbor.test.com
    

    修改文件属主

     chown -R named.named /var/named
    
  4. 重启服务

     systemctl restart named
    

3. 测试

用另外一台主机 使用dig命令测试

$ yum -y install bind-utils

$ dig @192.168.8.22 harbor.test.com +short
192.168.8.29

测试通过
