centos7安装dns正向解析1

安装软件

yum  -y  install  bind  bind-utils

备份一下文件

cp /etc/named.conf /etc/named.conf-123

vi /etc/named.con

options {
    
    
        directory       "/var/named";
};
 
logging {
    
    
        channel default_debug {
    
    
                file "data/named.run";
                severity dynamic;
        };
};

#域名1
zone "jbjb.com" IN {
    
    
        type master;
        file "jbjb.com.zone";
};
#域名2
zone "bbcc.com" IN {
    
    
        type master;
        file "bbcc.com.zone";
};

语法检测

named-checkconf

添加bbcc.com.zone,jbjb.com.zone文件

切换到数据库

cd /var/named/

cat jbjb.com.zone

$TTL 7200
jbjb.com.      IN SOA  jbjb.com.      1234.qq.com        (222    1H      15M     1W      1D)
jbjb.com.      IN      NS      dns1.imooc.com.
dns1.jbjb.com. IN      A       192.168.1.69
www.jbjb.com.  IN      A       192.168.1.66

cat bbcc.com.zone

$TTL 7200
bbcc.com.      IN SOA  bbcc.com.      1234.qq.com        (222    1H      15M     1W      1D)
bbcc.com.      IN      NS      dns1.bbcc.com.
dns1.bbcc.com. IN      A       192.168.1.69
www.bbcc.com.  IN      A       192.168.1.71

注意:邮箱地址，＠在DSN中是保留字符串，所以用.代替

改一下用户权限

chown root:named jbjb.com.zone bbcc.com.zone 

再次语法检测

[root@test69 named]# named-checkzone jbjb.com jbjb.com.zone 
zone jbjb.com/IN: loaded serial 222
OK

测试

客户端使用写上dns服务器的IP192.168.1.69

cat /etc/resolv.conf 
# Generated by NetworkManager
nameserver 192.168.1.69
