Today, I will talk to you about how to install bind on the Linux server. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Install bind

1. To install bind software, you need to install 3 bind, bind-chroot and bind-util.

[root@localhost pub] # yum install-y bind bind-chroot bind-utils

Installed:

Bind.i686 32 9.8.2-0.17.rc1.el6_4.6

Complete!

2. Modify the configuration file "/ etc/named.conf" and append "forward"

[root@localhost pub] # gedit / etc/named.conf

Options {

Listen-on port 53 {127.0.0.1;}

# 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 {localhost;}

Recursion yes

Dnssec-enable yes

Dnssec-validation yes

Dnssec-lookaside auto

/ * Path to ISC DLV key * /

Bindkeys-file "/ etc/named.iscdlv.key"

Managed-keys-directory "/ var/named/dynamic"

Forward only

Forwarders {

8.8.8.8

}

}

3. Set up the firewall, port 53 is needed here. Port 53 of tcp and udp needs to be opened. Remember to restart the firewall.

[root@localhost pub] # gedit / etc/sysconfig/iptables

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 443-j ACCEPT

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 53-j ACCEPT

-An INPUT-m state-- state NEW-m udp-p udp-- dport 53-j ACCEPT

[root@localhost phpMyAdmin] # service iptables restart

Iptables: set chain to policy ACCEPT:filter nat [OK]

Iptables: clear firewall rules: [OK]

Iptables: uninstalling module: [OK]

Iptables: apply firewall rules: [OK]

Iptables: load additional modules: nf_conntrack_ftp [OK]

[root@localhost phpMyAdmin] #

4. Start the service

[root@localhost pub] # service named start

Start named: [OK]

[root@localhost pub] #

5. Test. The command format is "dig website @ ip". Here, the loopback address is used to test whether the request is successful.

[root@localhost pub] # dig www.baidu.com @ 127.0.0.1

; DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 www.baidu.com @ 127.0.0.1
