bind：服务器

bind-utils：客户端（测试用）

配置文件：/etc/named.conf

客户端测试工具：/usr/bin/dig

• /usr/bin/host

• /usr/bin/nslookup

安装

yum -y install bind bind-utils

启动服务

systemctl start named

现在已经能够为自己提供dns服务了

为别的主机提供服务需修改配置文件

修改配置文件

vim /etc/named.conf

options {
	listen-on port 53 { localhost; };	#此处改为localhost 侦听的地址 或者注释掉或者删掉
	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; };  #此处改为any ，是允许所有主机来访问

	recursion yes;

	dnssec-enable yes;
	dnssec-validation yes;

	/* Path to ISC DLV key */
	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";  #named.ca 是根地址
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

配置文件相关

在配置zone的type时，有三种类型：

• hint：用来配置.的域名配置
• master：主服务器
• slave：从服务器

重新加载配置

rndc reload

此时别的主机就能访问本机DNS服务了
