CentOS7中配置DNS服务器

  查看某个区域开启的所有服务
  [root@localhost ~]# firewall-cmd --zone=public --list-all

1.配yum源
2.改主机名为jison.com
hostnamectl set-hostname jison.com
3.修改网卡的ip地址等命令
TYPE=Enternet
HWADDR=00:00:00:00:01
IPADDR=192.168.1.109
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.109
4.装包bind，bind-utils
yum install bind bind-utils
5.启named服务
systemctl enable named
systemctl start named
6.配/etc/named.conf、/etc/named.rfc1912.zones
（1）[root@yutianedu ~]# vim /etc/named.conf
options {
       listen-on port 53 { any; };               # 设置监听
        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; };           # 允许查询
recursion yes;
        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* 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";
include "/etc/named.root.key";

（2）# vim /etc/named.rfc1912.zones
# 在该文件的最末尾加入以下内容
zone "jison.com" IN {
        type master;
        file "jison.zone";
        allow-update { none; };
};
7.配zones
cd /var/named
cp -p named.localhost jison.zone
vi jison.zone
# cp –p /var/named/named.localhost   /var/named/jison.zone
# vim /var/named/google.zone
$TTL 7200
@       IN SOA ns.jison.com. root.jison.com. (
                                2014112499      ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
@       NS      ns.jison.com.
ns      A       172.25.254.201
www    A        172.25.254.201
ftp     A       172.25.254.12
8.重启named服务
systemctl restart named.service
9.在防火墙中允许外界访问named服务
firewall-cmd --permanent --add-service=dns
firewall-cmd --reload
10.测试：nslookup
vim /etc/resolv.conf
nameserver 172.25.254.201        # 指定DNS服务器地址

ping www.jison.com
