Learn about Linux DNS service setup for Beginners

To configure the DNS approximate steps:

1. Configure the IP address, and DNS points to itself.

2. Turn off the firewall and turn off SELinux.

3. Mount and install the bind package

4. Copy the configuration file

5. Configuring named.conf Primary Files

6. Configure forward and backward files

7. Configure the Forward file

8. Configuring Reverse Files

9. Restart the service

10. Testing Services

Body

1. Configure the IP address, and DNS points to itself.

[Email protected] ~]# Vim/etc/sysconfig/network-scripts/ifcfg-eth0

Configuration file:

Device=eth0

hwaddr=00:0c:29:95:7d:8e

Type=ethernet

uuid=de320e6a-e587-4419-bd9e-17d7c7833f9f

Onboot=yes

Nm_controlled=yes

Bootproto=static

ipaddr=192.168.10.10

netmask=255.255.255.0

Ipv6init=no

Userctl=no

dns1=192.168.10.10

: Wq

Save and exit

2. Turn off the firewall and turn off SELinux.

[[Email protected] ~]# service iptables stop

Iptables: Set the chain to policy accept:filter [OK]

Iptables: Clear Firewall rule: [OK]

Iptables: Uninstalling module: [OK]

[Email protected] ~]# Setenforce 0

[Email protected] ~]#

3. Mount and install the bind package

[Email protected] ~]# mkdir/test

[Email protected] ~]# mount/dev/sr0/test

Mount:block Device/dev/sr0 is write-protected, mounting read-only

[Email protected] ~]# cd/test/packages/

[Email protected] packages]# RPM-IVH bind-9.8.2-0.17.rc1.el6_4.6.i686.rpm bind-chroot-9.8.2-0.17.rc1.el6_4.6. i686.rpm cachefilesd-0.10.2-1.el6.i686.rpm

Warning:bind-9.8.2-0.17.rc1.el6_4.6.i686.rpm:header V3 rsa/sha1 Signature, key ID C105b9de:nokey

Preparing ... ########################################### [100%]

1:bind ########################################### [33%]

2:bind-chroot ########################################### [67%]

3:CACHEFILESD ########################################### [100%]

[Email protected] packages]#

Main three configuration files

bind-9.8.2-0.17.rc1.el6_4.6.i686.rpm

bind-chroot-9.8.2-0.17.rc1.el6_4.6.i686.rpm

cachefilesd-0.10.2-1.el6.i686.rpm

4. Copy the configuration file

[Email protected] packages]# cp-rp/usr/share/doc/bind-9.8.2/sample/*/var/named/chroot/

5. Configuring named.conf Primary Files

[Email protected] ~]# cd/var/named/chroot/etc/

[Email protected] etc]# vim named.conf

Set the line number with the "Set nu" command.

Then delete all the text after 110 lines.

Options

{

Directory "/var/named"; "Working" directory

Dump-file "Data/cache_dump.db";

Statistics-file "Data/named_stats.txt";

Memstatistics-file "Data/named_mem_stats.txt";

Listen-on Port: (any;};

LISTEN-ON-V6 Port: (any;};

allow-query {any;}; Change localhost to any

Allow-query-cache {any;};

recursion Yes;

Dnssec-enable Yes;

Dnssec-validation Yes;

Dnssec-lookaside Auto; Delete all comments

};

Logging//This profile is modified to delete the remaining important configuration

{

Channel Default_debug {

File "Data/named.run";

Severity dynamic;

};

};

View "Localhost_resolver"

{

match-clients {any;}; The Mark Red is mainly to be changed

recursion Yes;

Zone "." in {

Type hint;

File "/var/named/named.ca";

};

6. Configure forward and backward files

[Email protected] etc]# vim Named.rfc1912.zones

Zone "test.com" in {

Type master;

File "Named.localhost";

allow-update {none;};

}; Leave these two configurations, the other all deleted

Zone "10.168.192.in-addr.arpa" in {

Type master;

File "Named.loopback";

allow-update {none;};

};

7. Configure the Forward file

[Email protected] etc]# cd/var/named/chroot/var/named/

[Email protected] named]# vim Named.localhost

$TTL 1D

@ in SOA dns.test.com. Root. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

In NS dns.test.com. Don't forget the decimal point

DNS in A 192.168.10.10

www in A 192.168.10.10

FTP in A 192.168.10.10

Save exit

8. Configuring Reverse Files

[Email protected] named]# vim Named.loopback

$TTL 1D

@ in SOA dns.test.com. Root. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

In NS dns.test.com.

Ten in PTR dns.test.com.

Ten in PTR www.test.com.

Ten in PTR ftp.test.com.

9. Restart the service

[Email protected] named]# service network restart

Shutting down interface eth0: Device status: 3 (Disconnected)

Determine

Close Loopback interface: [OK]

Eject loopback interface: [OK]

Popup interface eth0: Active connection Status: activated

Active connection path:/ORG/FREEDESKTOP/NETWORKMANAGER/ACTIVECONNECTION/2

Determine

[Email protected] named]# service named restart

Stop named:[OK]

generating/etc/rndc.key:[OK]

Start named:[OK]

[Email protected] named]#

10. Testing

[email protected] named]# nslookup 192.168.10.10

server:192.168.10.10

address:192.168.10.10#53

10.10.168.192.in-addr.arpa name = dns.test.com.

10.10.168.192.in-addr.arpa name = www.test.com.

10.10.168.192.in-addr.arpa name = ftp.test.com.

The analysis proves that we are successful.
