CentOS7安装配置DNS服务器

#更改主机名称
#vi /etc/sysconfig/network
# Created by anaconda
NETWORKING=yes
HOSTNAME=bigcloud.local
#修改文件/etc/hosts,内容如下：
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.188.135  bigcloud bigcloud.localdomain
#修改DNS配置
# vi /etc/resolv.conf
添加如下
DNS1=192.168.188.11
DNS2=192.168.188.12
DOMAIN=bigcloud.local
安装bind
rpm -Uvh bind-9.9.4-14.el7.x86_64.rpm

#启动服务 
# service named start
Redirecting to /bin/systemctl start  named.service
#修改配置文件。 
#在修改之前，先进行备份，这是一个好习惯 
# cp /etc/named.conf  /etc/named.conf.bak
# vi /etc/named.conf  
#建议：先将原有配置注释，再写新的配置，如下所示 
options { 
        //listen-on port 53 { 127.0.0.1; }; 
        listen-on port 53 { any; }; 
 
#将 dnssec 设置"yes"修改为 no，示例如下： 
        //dnssec-enable yes; 
        dnssec-enable no; 
        //dnssec-validation yes; 
        dnssec-validation no; 
        dnssec-lookaside auto; 
 
#将 allow-query 设置修改为 any，示例如下： 
        //allow-query     { localhost; }; 
        allow-query     { any; }; 
allow-transfer { 192.168.188.11; 192.168.188.12; };#设置辅助DNS的地址
forwarders {202.102.224.68; 202.102.227.68; }; # 配置DNS转发器
};
 
 
 
// LEAUS Add  添加正向ZONE
zone "bigcloud.local" IN {
        type master;
        file "bigcloud.zone";
};
//添加反向ZONE
zone "0.0.10.in-addr.arpa" IN { 
#此处IP地址根据自己所设置的网段不同而更改
        type master; 
        file "10.0.0.zone"; 
}; 
#创建ZONE文件
#cd /var/named/
#vi bigcloud.zone
