篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了centos7配置YUM安装DNS服务相关的知识，希望对你有一定的参考价值。
1、配置DNS地址
vim /etc/resolv.conf nameserver 192.168.1.100 #注：这里的地址是你DNS服务器本机的地址
2、安装dns服务
yum install bind bind-utils
3、启动服务
启动DNS服务：service named start 重启DNS服务：systemctl restart named.service 设置开机启动：systemctl enable named
4、编辑dns配置文件
vim /etc/named.conf
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";
allow-query { any;};
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
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";
};
#新增demo.com域名
zone "demo.com" {
type master;
file "/var/named/demo.com";
};
#新增demo1.com域名
zone "demo1.com" {
type master;
file "/var/named/demo1.com";
};
#include "/etc/named.rfc1912.zones";
#include "/etc/named.root.key";
#zone "testdongy.com" {
# type master;
# file "/var/named/testdongy.com";
#};#如上是我已经配置好的，复制即可
5、配置DNS域解析文件
vim /var/named/demo1.com $TTL 3H @ IN SOA @ demo1.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 AAAA ::1 a IN A 192.168.2.171 b IN A 192.168.2.172 www IN A 192.168.2.171 dev IN A 192.168.2.171
最后重启一下DNS服务器即可,客户机只需指定所配置的地址即可验证。
systemctl restart named.service
6、下面是我win7的DNS配置192.168.2.107
连接特定的 DNS 后缀: 描述: Realtek PCIe GBE Family Controller 物理地址: B0-83-FE-83-A4-4B 已启用 DHCP: 否 IPv4 地址: 192.168.2.102 IPv4 子网掩码: 255.255.255.0 IPv4 默认网关: 192.168.2.1 IPv4 DNS 服务器: 192.168.2.107, 223.5.5.5 IPv4 WINS 服务器: 已启用 NetBios over Tcpip: 是 连接-本地 IPv6 地址: fe80::d25:5b:dda3:f08d%11 IPv6 默认网关: IPv6 DNS 服务器:
7、开始验证
如下就是验证所得结果，好了，验证成功，服务完成了。
