ubuntu22.04配置bind9（dns服务器配置）

1.安装bind9

ubuntu@dns:~$ sudo  su -
[sudo] password for ubuntu:
root@dns:~# apt install bind9

2.指定解析文件

root@dns:~# vim /etc/bind/named.conf.default-zones
// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/usr/share/dns/root.hints";
};
 
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
 
zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};
 
zone "127.in-addr.arpa" {
        type master;
        file "/etc/bind/db.127";
};
 
zone "0.in-addr.arpa" {
        type master;
        file "/etc/bind/db.0";
};
 
zone "255.in-addr.arpa" {
        type master;
        file "/etc/bind/db.255";
};
 
zone "openstack.jiangxi" {       # 此处指定域名
        type master;
        file "/etc/bind/db.openstack.jiangxi";   #指定域名数据库存放位置
};
 

3.配置域名数据库文件

root@dns:~# vim /etc/bind/db.openstack.jiangxi
$TTL 1D
@    IN    SOA    master    admin.openstack.jiangxi.    ( 1 1D 5H 5H 2H )
           NS     master
master     A      192.168.80.83
controller A      192.168.80.80
compute01  A      192.168.80.81
compute02  A      192.168.80.82
 
 
root@dns:~# systemctl restart bind9    #重启bind9服务
