提供DNS服务的软件bind,服务名named
[root@localhost ~]# yum install bind -y [root@localhost ~]# rpm -ql bind //查看bind生成的文件 /etc/named.conf //bind主配置文件 /etc/named.rfc1912.zones //定义zone的文件 /var/named/named.ca //根解析库文件 /var/named/slaves //从ns服务器文件夹 [root@localhost ~]# cp -a /etc/named.conf /etc/named.bak //文件备份 -a不会改变文件的所属者，所属组，时间等。 1>如果直接cp 的话相当于创建一个新文件把/etc/named.conf的内容复制进去。 针对1> 方法：chown root:named /etc/named.conf
关闭防火墙，selinux
[root@localhost ~]#systemctl stop status firewalld [root@localhost ~]#setenforce 0
修改主配置文件
[root@localhost ~]# vim /etc/named.conf
[root@localhost ~]# cat /etc/named.conf
options {
listen-on port 53 { 192.168.189.128; };
directory "/var/named";
};
zone "zuoye.com" IN {
type master;
file "named.zuoye.com";
};
添加文件
[root@localhost ~]# cd /var/named [root@localhost named]# vim named.zuoye.com [root@localhost named]# cat named.zuoye.com $TTL 1D @ IN SOA master.zuoye.com. admin.zuoye.com. ( 1016 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum IN NS master.zuoye.com. wwww IN CNAME www.zuoye.com. master IN A 192.168.189.128 www IN A 192.168.189.128 [root@localhost named]# systemctl restart named //重启DNS服务
修改主机DNS解析的优先性
[root@localhost named]# vim /etc/resolv.conf [root@localhost named]# cat /etc/resolv.conf # Generated by NetworkManager search localdomain nameserver 192.168.189.128 nameserver 192.168.189.22
