Linux DNS Service installation configuration

System Conventions:

1. Domain Name: redhat.com

2, ns:192.168.101.168

3, web:192.168.101.11, 192.168.101.12

4, mail:192.168.101.10

1. Install bind

Yum Install Bind-libs bind-utils bind

2. Turn off SELinux, firewall

Vim/etc/selinux/config

Selinux=disabled

Setenforce 0

Service Iptables Stop

Chkconfig iptables off

3. Configure bind

Cp/etc/named.conf/etc/named.conf.bak

Vim/etc/named.conf

Options {

Directory "/var/named";

# limit IP Recursive queries

allow-recursion {192.168.101.0/24;};

};

Zone "." in {

Type hint;

File "named.ca";

};

Zone "localhost" in {

Type master;

File "Named.localhost";

};

Zone "0.0.127.in-addr.arpa" in {

Type master;

File "Named.loopback";

};

4. Modify DNS

Vim/etc/resolv.conf

NameServer 192.168.101.168

5. Test configuration file

Named-checkzone "localhost"/var/named/named.localhost

Named-checkzone "0.0.127.in-addr.arpa"/var/named/named.loopback

6. Start bind

# during startup if the quote: Generating/etc/rndc.key

# workaround generates a rndc-key:

Rndc-confgen-r/dev/urandom-a

Service named start

7. Test to find root DNS

Dig-t NS. @192.168.101.168

Ping www.baidu.com

Chkconfig named on

# At this point a DNS cache server configuration is complete.

8. Configuration forward parsing

Vim/etc/named.conf

Add

Zone "Redhat.com" in {

Type master;

File "Redhat.com.zone";

};

9. Add forward parsing configuration file

Vim/var/named/redhat.com.zone

$TTL 86400

@ in SOA ns1.redhat.com. Admin.redhat.com. (

2015010101; Serial

1H; Refresh

5M; Retry

1W; Expire

3H); Minimum

In NS ns1

In MX ten Mail

NS1 in A 192.168.101.168

Mail in A 192.168.101.10

www in A 192.168.101.11

www in A 192.168.101.12

# License Related Documents

chmod 640/var/named/redhat.com.zone

Chgrp Named/var/named/redhat.com.zone

10. Configure Reverse resolution

Vim/etc/named.conf

Add

Zone "101.168.192.in-addr.arpa" in {

Type master;

File "192.168.101.zone";

};

11. Add Reverse resolution configuration file

Vim/var/named/192.168.101.zone

$TTL 86400

@ in SOA ns1.redhat.com. Admin.redhat.com. (

2015010101; Serial

1H; Refresh

5M; Retry

1W; Expire

3H); Minimum

In NS ns1.redhat.com.

168 in PTR ns1.redhat.com.

Ten in PTR mail.redhat.com.

One in PTR www.redhat.com.

In PTR www.redhat.com.

12. Test and restart

Named-checkconf

Named-checkzone "Redhat.com"/var/named/redhat.com.zone

Named-checkzone "101.168.192.in-addr.arpa"/var/named/192.168.101.zone

Service named restart
