Linux-centos7.4-dns II (Build a separate DNS server for resolution)

Environment:
Linux Server one (dual NIC)
Intranet ip:192.168.80.180
External network ip:192.168.90.180
Linux client one, IP address: 192.168.80.10
Win7 client One, IP address: 192.168.90.10
Ensure network interoperability between server and two clients,
Server testing

Linux Client Testing

Win7 Client Testing

First step: Server Configuration
--------------1. Installation Service----------------
[[email protected] ~]# Yum install-y bind bind-utils//install DNS service with nslookup command
[[email protected] ~]# systemctl stop FIREWALLD//Turn off firewall
[[email protected] ~]# Setenforce 0//Turn off SELinux
-------------2. Edit the master configuration file---------------
[Email protected] ~]# vi/etc/named.conf
...............
Options {
Listen-on Port: (any;}; Listen to all addresses on the server
Listen-on-v6 Port 53 {:: 1;};
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;}; Allow all people to access
Skip to line 52 and delete the following four lines (delete the zone opening)
Zone "." in {
Type hint;
File "named.ca";
};
Save exit
[[email protected] ~]# named-checkconf//Check syntax error
---------------3. Edit the Zone profile----------------
[Email protected] ~]# Vi/etc/named.rfc1912.zones
Delete all zone openings (or add a view configuration above each)
Add the following content:
View "LAN" {//config Intranet
match-clients {192.168.80.0/24;};
Zone "Hello.com" in {
Type master;
File "Hello.com.zone.lan";
};
};
View "WAN" {//Configure Extranet
match-clients {any;};
Zone "Hello.com" in {
Type master;
File "Hello.com.zone.wan";
};
};
Save exit
[[email protected] ~]# named-checkconf//Check syntax error
----------4. Edit the Zone data profile------------
[Email protected] ~]# cd/var/named
[[email protected] named]# cp-p named.localhost Hello.com.zone.lan//Create Intranet Zone data profile
[[email protected] named]# cp-p named.localhost Hello.com.zone.wan//Create an Extranet zone data profile
[[Email protected] named]# VI Hello.com.zone.lan//Edit Intranet area data profile
Modify the following configuration:
$TTL 1D
@ in SOA @ rname.invalid. (
0; Serial
1D; Refresh
1H; Retry
1W; Expire
3H); Minimum
NS @
A 192.168.80.180//native address
www in A 192.168.80.180//www.hello.com corresponding address
Save exit
[[Email protected] named]# VI Hello.com.zone.wan//Edit extranet Zone Data profile
Modify the following configuration:
$TTL 1D
@ in SOA @ rname.invalid. (
0; Serial
1D; Refresh
1H; Retry
1W; Expire
3H); Minimum
NS @
A 192.168.90.180//native address
www in A 192.168.90.180//www.hello.com corresponding address
Save exit
[[email protected] named]# named-checkconf//Check syntax
----------5. Start the service----------------
[[email protected] named]# systemctl start named//Start DNS Service
[Email protected] named]# Netstat-anpu | grep named//view DNS service status
Show

Step Two: Client testing
---------1.linux Client Test-----------
[[email protected] ~]# systemctl stop FIREWALLD//Turn off firewall
[[email protected] ~]# Setenforce 0//Turn off SELinux
[[email protected] ~]# vi/etc/resolv.conf//Configure DNS
Add domain Name: (all other delete)
NameServer 192.168.80.180
Save exit
[email protected] ~]# nslookup www.hello.com//parsing www.hello.com

Successful parsing
---------2.win7 Client Test----------
Shutting down the firewall
Add DNS to 192.168.90.180,

Parse www.hello.com,

Parse success
