CentOS 6.5 DNS Server Setup

Brief steps:

1. Add the domain in the main configuration file of bind

2. Create a zone file for the domain in/var/named

3. Edit the zone file to add the required information

4. Detect firewall or SELinux settings

5. Start the BIND service and restart the network service

6. Client-side test domain name resolution

1. Installing the DNS server components

Install bind

Yum-y Install bind bind-chroot bind-util bind-libs

2. Edit the DNS master configuration file

vi/etc/named.conf Modify the master configuration file, such as:

Edit complete, save exit

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M01/84/17/wKioL1eFptOB5c4KAABST7VsWsY491.png "title=" 1.png " alt= "Wkiol1efptob5c4kaabst7vswsy491.png"/>

3, then modify the Named.rfc1912.zones file, Vi/etc/named.rfc1912.zones, such as:

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/84/17/wKioL1eFpu_CnzNoAABaiinoDlI966.png "title=" 2.png " alt= "Wkiol1efpu_cnznoaabaiinodli966.png"/>

4. Add set DNS forward parsing

Modify zone configuration file, forward parsing:

#cd/var/named/

#cp Named.localhost soundmobii.com

#vi soundmobii.com (same as the zone file name defined in the main profile [/etc/named.rfc1912.zones])

$TTL 1D

@ in SOA @ ns.soundmobii.com. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

@ in NS ns.soundmobii.com.

NS in A 192.168.2.98

Tomcat in CNAME NS

5, modify the zone configuration file, reverse parsing:

#cd/var/named/

#cp Named.localhost 2.168.192.in-addr.arpa

#vi 2.168.192.in-addr.arpa (to match the zone file name defined in the main configuration [/etc/named.rfc1912.zones] file)

$TTL 1D

@ in SOA @ ns.soundmobii.com. (

0; Serial

1D; Refresh

1H; Retry

1W; Expire

3H); Minimum

@ NS ns.soundmobii.com.

98 in PTR ns.soundmobii.com.

6. Change firewall settings and SELinux settings

Getenforce (see if SELinux is turned on)

Setenforce 0

Vi/etc/sysconfig/iptables #配置防火墙端口

-ainput-m State--state new-m tcp-p TCP--dport 53-j ACCEPT

-ainput-m State--state new-m udp-p UDP--dport 53-j ACCEPT

-ainput-m State--state new-m tcp-p TCP--dport 953-j ACCEPT

Service iptables Restart #重启防火墙 to make the rules effective

7. Start the DNS service (note that the DNS services name is called bind in Linux)

Service named start

8, test the detection domain information is normal (important)

Check to see if the configuration file has Read permission before checking ll/var/named

(if not read full line, chmod +r/var/named/* can)

650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M02/84/18/wKiom1eFpzqBVtAaAABcJG_6mlQ529.png "title=" 3.png " alt= "Wkiom1efpzqbvtaaaabcjg_6mlq529.png"/>

9, check the bind file configuration process error prone

The following commands are used to check the bind configuration file and zone file syntax

Named-checkconf/etc/named.conf

Named-checkzone soundmobii.com/var/named/soundmobii.com

10

10. Start the restart DNS service to view service status

Service named restart

Service Network restart

User-side test parsing, test through Nslookup.
