Debian——DNS

---

前言

版本Debian10.7,三台机子，server/node1/node2

---

一、环境

192.168.26.10 server server.zedd.com
192.168.26.11 node1 node1.zedd.com
192.168.26.12 node2 node2.zedd.com

二、主机名修改、安装

1.修改主机名

root@debian:~# echo server > /etc/hostname
root@debian:~# vim /etc/hosts
127.0.1.1       server.zedd.com server //修改
//保存退出，更新主机名
root@debian:~# hostname -F /etc/hostname
root@debian:~# hostname
server
root@debian:~# hostname -f
server.zedd.com
root@debian:~# bash
root@server:~#

node1/node2 相同操作

2.安装

root@server:~# apt install bind9 dnsutils -y
root@node1:~# apt install dnsutils -y
root@node2:~# apt install dnsutils -y

---

二、配置

1.修改工作目录路径

root@server:~# cd /etc/bind/
root@server:/etc/bind# vim named.conf.options
directory "/etc/bind/";		//修改

2.添加区域

root@server:/etc/bind# vim named.conf

正向区域文件创建

root@server:/etc/bind# cp db.empty db.zedd
root@server:/etc/bind# vim db.zedd

反向区域文件创建

root@server:/etc/bind# cp db.127 db.ddez
root@server:/etc/bind# vim db.ddez

权限
chown -R bind:bind /etc/bind

三、测试

//重启服务,添加DNS
root@server:/etc/bind# systemctl restart bind9
root@server:/etc/bind# cat /etc/resolv.conf
nameserver 192.168.26.10		//添加
nameserver 8.8.8.8
root@node1:~# cat /etc/resolv.conf
nameserver 192.168.26.10
root@node2:~# cat /etc/resolv.conf
nameserver 192.168.26.10

server
