1、准备
例：两台192.168.11.10(主),192.168.11.11(从),域名www.test1.com
# 主从DNS服务器均需要安装bind、bind-chroot、bind-utils yum -y install bind bind-utils bind-chroot # 如果防火墙开启，配置防火墙，添加服务(防火墙已禁用则忽略) firewall-cmd --permanent --add-service=dns firewall-cmd --reload
2、主DNS服务器(192.168.11.10)配置
# 编辑配置文件
vim /etc/named.conf
# 找到其中两行
listen-on port 53 { 127.0.0.1; };
allow-query { localhost; };
# 修改为
listen-on port 53 { any; };
allow-query { any; };
3、配置正向解析
# 编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域
zone "test1.com" IN {
type master;
file "data/test1.com.zone";
};
# 创建test1.com.zone解析域
vim /var/named/data/test1.com.zone
$TTL 3H
@ IN SOA test1.com. root (
20180928 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
IN NS @
IN A 192.168.11.10
www IN A 192.168.11.10
ftp IN A 192.168.11.10
# 编辑/etc/resolv.conf，添加
search localdomain
nameserver 192.168.11.10
4、重启DNS服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
5、检查解析是否成功
# ping命令验证 ping -c 4 www.test1.com # 输出如下即解析成功 PING www.test1.com (192.168.11.10) 56(84) bytes of data. 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=3 ttl=64 time=0.066 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=4 ttl=64 time=0.057 ms --- www.test1.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.033/0.053/0.066/0.014 ms # nslookup命令验证 nslookup >www.test1.com # 输出如下即解析成功 Server: 192.168.11.10 Address: 192.168.11.10#53 Name: www.test1.com Address: 192.168.11.10
6、配置反向解析
# 编辑文件/etc/named.rfc1912.zones，在末尾添加
vim etc/named.rfc1912.zones
zone "11.168.192.in-addr.arpa" IN {
type master;
file "data/11.168.192.zone";
};
# 创建11.168.192.zone解析域
vim /var/named/data/11.168.192.zone
$TTL 3H
@ IN SOA web3.com. root (
20180928; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS www.test1.com.
10 IN PTR www.test1.com.
10 IN PTR ftp.test1.com.
7、重启DNS服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
8、检查解析是否成功
# ping命令验证 ping -c 4 192.168.11.10 # 输出如下即解析成功 PING 192.168.11.10 (192.168.11.10) 56(84) bytes of data. 64 bytes from 192.168.11.10: icmp_seq=1 ttl=64 time=0.061 ms 64 bytes from 192.168.11.10: icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from 192.168.11.10: icmp_seq=3 ttl=64 time=0.081 ms 64 bytes from 192.168.11.10: icmp_seq=4 ttl=64 time=0.060 ms --- 192.168.11.10 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.058/0.065/0.081/0.009 ms # nslookup命令验证 nslookup 192.168.11.10 # 输出如下即解析成功 Server: 192.168.11.10 Address: 192.168.11.10#53 10.11.168.192.in-addr.arpa name = ftp.test1.com. 10.11.168.192.in-addr.arpa name = www.test1.com.
9、配置从DNS服务器(192.168.11.11)
# 先修改主DNS服务器(192.168.11.10)的配置/etc/named.rfc1912.zones
vim /etc/named.rfc1912.zones
zone "test1.com" IN {
type master;
file "data/test1.com.zone";
allow-transfer {192.168.11.11;};
notify yes;
also-notify {192.168.11.11;};
};
zone "11.168.192.in-addr.arpa" IN {
type master;
file "data/11.168.192.zone";
allow-transfer {192.168.11.11;};
notify yes;
also-notify {192.168.11.11;};
};
10、配置从DNS服务器(192.168.11.11)正向解析
# 编辑named.conf文件
vim /etc/named.conf
# 找到其中两行
listen-on port 53 { 127.0.0.1; };
allow-query { localhost; };
# 修改为
listen-on port 53 { any; };
allow-query { any; };
# 编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域
vim /etc/named.rfc1912.zones
zone "test1.com" IN {
type slave;
file "data/test1.com.zone"; };
masters { 192.168.11.10; };
# 创建test1.com.zonek空文件
touch /var/named/data/test1.com.zone
# 设置所有者
chown named:named test1.com.zone
# 编辑/etc/resolv.conf，添加
vim /etc/resolv.conf
search localdomain
nameserver 192.168.11.11
11、重启DNS服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
12、检测解析是否成功
# ping命令验证 ping -c 4 www.test1.com # 输出如下即解析成功 PING www.test1.com (192.168.11.10) 56(84) bytes of data. 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=3 ttl=64 time=0.066 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=4 ttl=64 time=0.057 ms --- www.test1.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.033/0.053/0.066/0.014 ms # nslookup命令验证 nslookup >www.test1.com # 输出如下即解析成功 Server: 192.168.11.11 Address: 192.168.11.11#53 Name: www.test1.com Address: 192.168.11.10
13、配置从DNS服务器(192.168.11.11)反向解析
# 在文件/etc/named.rfc1912.zones中添加
vim etc/named.rfc1912.zones
zone "11.168.192.in-addr.arpa" IN {
type master;
file "data/11.168.192.zone";
masters { 192.168.11.10; };
};
# 创建空文件11.168.192.zone
touch /var/named/data/11.168.192.zone
# 设置所有者
chown named:named 11.168.192.zone
14、重启DNS服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
15、查看文件/var/named/data/test1.com.zone和/var/named/data/11.168.192.zone是否有二进制数据
cat /var/named/data/test1.com.zone cat /var/named/data/11.168.192.zone
16、检查解析是否成功
# ping命令验证 ping -c 4 192.168.11.11 # 输出如下即解析成功 PING 192.168.11.11 (192.168.11.11) 56(84) bytes of data. 64 bytes from 192.168.11.11: icmp_seq=1 ttl=64 time=0.061 ms 64 bytes from 192.168.11.11: icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from 192.168.11.11: icmp_seq=3 ttl=64 time=0.081 ms 64 bytes from 192.168.11.11: icmp_seq=4 ttl=64 time=0.060 ms --- 192.168.11.11 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.058/0.065/0.081/0.009 ms # nslookup命令验证 nslookup 192.168.11.11 # 输出如下即解析成功 Server: 192.168.11.11 Address: 192.168.11.11#53 10.11.168.192.in-addr.arpa name = ftp.test1.com. 10.11.168.192.in-addr.arpa name = www.test1.com.
