Linux_配置辅助DNS服务（基础）
【RHEL8】—DNSserver1；【RHEL7】—DNSserver2；【Centos7】—DNSclient
！！！测试环境我们首关闭防火墙和selinux（DNSserver1、DNSserver2、DNSclient都需要）
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@localhost ~]# setenforce 0

一、在DNSserver1和DNSserver2上安装DNS服务
1、安装DNS服务
//DNSserver1
[root@DNSserver1 ~]# yum install -y bind
[root@DNSserver1 ~]# systemctl start named
[root@DNSserver1 ~]# systemctl enable named
Created symlink /etc/systemd/system/multi-user.target.wants/named.service → /usr/lib/systemd/system/named.service.
//DNSserver2
[root@dnsserver2 ~]# yum install -y bind
[root@dnsserver2 ~]# systemctl start named
[root@dnsserver2 ~]# systemctl enable named
Created symlink from /etc/systemd/system/multi-user.target.wants/named.service to /usr/lib/systemd/system/named.service.
2、查看IP
//DNSserver1
[root@DNSserver1 ~]# ifconfig
ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.0.140 netmask 255.0.0.0 broadcast 10.255.255.255
inet6 fe80::fa13:32e0:3b9f:2196 prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:cd:6a:1b txqueuelen 1000 (Ethernet)
RX packets 1848 bytes 164945 (161.0 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1399 bytes 195583 (190.9 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 596 bytes 50400 (49.2 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 596 bytes 50400 (49.2 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
//DNSserver2
[root@dnsserver2 ~]# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.0.150 netmask 255.255.255.0 broadcast 10.0.0.255
inet6 fe80::e220:bff8:e997:50c4 prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:b3:4d:83 txqueuelen 1000 (Ethernet)
RX packets 1786 bytes 137533 (134.3 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1638 bytes 355972 (347.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 68 bytes 5772 (5.6 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 68 bytes 5772 (5.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
二、编辑配置文件
1、在/etc/named.conf文件里面修改全局配置信息（DNSserver1和DNSserver2都需要修改）
//DNSserver1
[root@DNSserver1 ~]# vim /etc/named.conf
.........
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
secroots-file "/var/named/data/named.secroots";
recursing-file "/var/named/data/named.recursing";
allow-query { any; };
.........
//DNSserver2
[root@dnsserver2 ~]# vim /etc/named.conf
.........
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { any; };
.........
2、在DNSserver1上配置：在/etc/named.rfc1912.zones子配置文件里面添加正向和反向的解析区域
[root@DNSserver1 ~]# arpaname 10.0.0.140
[root@DNSserver1 ~]# vim /etc/named.rfc1912.zones
.........
zone "test.com" IN {
type master;
file "test.zone";
allow-transfer { 10.0.0.150; };
}; zone "0.0.10.in-addr.arpa" IN {
type master;
file "10.0.0.arpa";
allow-transfer { 10.0.0.150; };
};
//在文件的最后添加
3、在DNSserver2上配置：在/etc/named.rfc1912.zones子配置文件里面添加正向和反向的解析区域
[root@dnsserver2 ~]# arpaname 10.0.0.150
150.0.0.10.IN-ADDR.ARPA
[root@dnsserver2 ~]# vim /etc/named.rfc1912.zones
..........
zone "test.com" IN {
type slave;
masters { 10.0.0.140; };
file "slaves/test.zone";
}; zone "0.0.10.in-addr.arpa" IN {
type slave;
masters { 10.0.0.140; };
file "slaves/10.0.0.arpa";
};
//在文件的最后添加
4、在DNSserver1上配置：复制生成正向和反向区域解析数据库文件
[root@DNSserver1 ~]# cd /var/named/
[root@DNSserver1 named]# ls
data dynamic named.ca named.empty named.localhost named.loopback slaves
[root@DNSserver1 named]# cp -a named.localhost test.zone
[root@DNSserver1 named]# cp -a named.loopback 10.0.0.arpa
5、在DNSserver1上配置：编辑正向区域解析数据库文件
[root@DNSserver1 named]# vim test.zone
$TTL 1D
@ IN SOA test.com. root.test.com. (
2020031601 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns1.test.com.
NS ns2.test.com.
A 127.0.0.1
AAAA ::1
ns1 A 10.0.0.140
ns2 A 10.0.0.150
www A 10.0.0.1
aaa A 10.0.0.2
bbb A 10.0.0.3
ccc A 10.0.0.4
ddd A 10.0.0.5
6、在DNSserver1上配置：编辑反向区域解析数据库文件
[root@DNSserver1 named]# vim 10.0.0.arpa
$TTL 1D
@ IN SOA test.com root.test.com. (
2020031601 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns1.test.com.
NS ns2.tst.com.
A 127.0.0.1
AAAA ::1
PTR localhost.
ns1 A 10.0.0.140
ns2 A 10.0.0.150
1 PTR www
2 PTR aaa
3 PTR bbb
4 PTR ccc.test.com
5 PTR ddd.test.com
7、在DNSserver1、DNSserver2上配置：配置文件语法检测
//DNSserver1
[root@DNSserver1 ~]# named-checkconf /etc/named.conf
[root@DNSserver1 ~]# named-checkconf /etc/named.rfc1912.zones
//DNSserver2
[root@dnsserver2 ~]# named-checkconf /etc/named.conf
[root@dnsserver2 ~]# named-checkconf /etc/named.rfc1912.zones
8、在DNSserver1上配置：正向和反向区域解析测试
[root@DNSserver1 ~]# named-checkzone test.com /var/named/test.zone
zone test.com/IN: loaded serial 2020031601
OK
[root@DNSserver1 ~]# named-checkzone test.com /var/named/10.0.0.arpa
zone test.com/IN: loaded serial 2020031601
OK
9、重启DNS服务，查看端口（DNSserver1和DNSserver2都需要）
//DNSserver1
[root@DNSserver1 ~]# systemctl restart named
[root@DNSserver1 ~]# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

//DNSserver2
[root@dnsserver2 ~]# systemctl restart named
[root@dnsserver2 ~]# netstat -tunlp
Active Internet connections (only servers)

udp6 0 0 :::53 :::* 2118/named
udp6 0 0 ::1:323 :::* 767/chronyd
10、在DNSserver2上检查是否获取正向和反向区域解析数据库文件
[root@dnsserver2 ~]# ll /var/named/slaves/
总用量 8
-rw-r--r--. 1 named named 834 7月 30 09:52 10.0.0.arpa
-rw-r--r--. 1 named named 527 7月 30 09:52 test.zone
到这里DNS服务端搭建完成
三、DNS客户端测试
1、查看客户端主机的IP
[root@dnsclient ~]# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.0.129 netmask 255.255.255.0 broadcast 10.0.0.255
inet6 fe80::fe04:212a:5e53:cec4 prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:b3:89:a5 txqueuelen 1000 (Ethernet)
RX packets 22880 bytes 29553230 (28.1 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 4707 bytes 583379 (569.7 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 148 bytes 12796 (12.4 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 148 bytes 12796 (12.4 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
2、测试是否能与服务器端互通
[root@dnsclient ~]# ping -c 3 10.0.0.140
PING 10.0.0.140 (10.0.0.140) 56(84) bytes of data.
64 bytes from 10.0.0.140: icmp_seq=1 ttl=64 time=2.15 ms
64 bytes from 10.0.0.140: icmp_seq=2 ttl=64 time=0.403 ms
64 bytes from 10.0.0.140: icmp_seq=3 ttl=64 time=0.424 ms --- 10.0.0.140 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 0.403/0.993/2.153/0.820 ms
3、安装bind-utils包
[root@dnsclient ~]# yum install -y bind-utils
[root@dnsclient ~]# rpm -qa bind-utils
bind-utils-9.11.4-16.P2.el7_8.6.x86_64
4、在客户端 /etc/resolv.conf 加入服务端的DNS
[root@dnsclient ~]# vim /etc/resolv.conf
[root@dnsclient ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 10.0.0.140
nameserver 10.0.0.150
nameserver 8.8.8.8
5、测试
[root@dnsclient ~]# nslookup www.test.com
Server: 10.0.0.140
Address: 10.0.0.140#53 Name: www.test.com
Address: 10.0.0.1
[root@dnsclient ~]# nslookup 10.0.0.1
1.0.0.10.in-addr.arpa name = www.0.0.10.in-addr.arpa. [root@dnsclient ~]# nslookup aaa.test.com
Server: 10.0.0.140
Address: 10.0.0.140#53 Name: aaa.test.com
Address: 10.0.0.2
[root@dnsclient ~]# nslookup 10.0.0.2
2.0.0.10.in-addr.arpa name = aaa.0.0.10.in-addr.arpa. [root@dnsclient ~]# nslookup bbb.test.com
Server: 10.0.0.140
Address: 10.0.0.140#53 Name: bbb.test.com
Address: 10.0.0.3
[root@dnsclient ~]# nslookup 10.0.0.3
3.0.0.10.in-addr.arpa name = bbb.0.0.10.in-addr.arpa. [root@dnsclient ~]# nslookup ccc.test.com
Server: 10.0.0.140
Address: 10.0.0.140#53 Name: ccc.test.com
Address: 10.0.0.4
[root@dnsclient ~]# nslookup 10.0.0.4
4.0.0.10.in-addr.arpa name = ccc.test.com.0.0.10.in-addr.arpa. [root@dnsclient ~]# nslookup ddd.test.com
Server: 10.0.0.140
Address: 10.0.0.140#53 Name: ddd.test.com
Address: 10.0.0.5
[root@dnsclient ~]# nslookup 10.0.0.5
5.0.0.10.in-addr.arpa name = ddd.test.com.0.0.10.in-addr.arpa. [root@dnsclient ~]# nslookup
> server 10.0.0.13
Default server: 10.0.0.13
Address: 10.0.0.13#53
> set q=mx
> test.com
