DNS domain name system
Features: (1) recursive query and iterative Query
(2) Distributed Database
(3) Resolve the domain name to an IP address
(4) three types of DNS are available: primary DNS server, secondary DNS server, and cache DNS server.
(5) 13 Global root domain servers

1. Software Package
Bind. i386 -- main service package
Bind-chroot.i386-cage environment Software Package
Bind-devel.i386-Development Kit
Bind-libs.i386-library files
Bind-utils.i386-Toolkit
[Root @ rootbug ~] # Rpm-qa | package under grep ^ bind--- rhel6.3
Bind-utils-9.8.2-0.10.rc1.el6.x86_64
Bind-chroot-9.8.2-0.10.rc1.el6.x86_64

Bind-dyndb-ldap-1.1.0-0.9.b1.el6.x86_64
------------- Why is the software package tangled ?? Because the names of these software packages have a relationship with each half of the three DNS words ---------

2. install the software package
[Root @ rootbug ~] # Yum install bind *-y

3. view the configuration file
In RHEL6, whether bind-chroot is installed or not, the configuration files are mainly/var/named. conf files.
(1) Modify/etc/named. conf
[Root @ rootbug ~] # Vim/etc/named. conf
------- Omit other 10 million lines of code ----------------

Options {
Listen-on port 53 {any ;}; -- change 127.0.0.1 in the original configuration file to any, which indicates listening to all
Listen-on-v6 port 53 {: 1 ;};
Directory "/var/named"; -- directory for storing domain data files
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;}; -- change the localhost of the configuration file to any, which indicates that everyone can query this server.
Recursion yes;

------- Omit other 10 million lines of code ----------------
Save the modification and exit.
(2) Configure/etc/named. rfc1912.zones and add the domain configuration.
[Root @ rootbug ~] # Vim/etc/named. rfc1912.zones
Add a Domain According to the configuration file format. Here I add a rootbug.com domain. The data file of the domain is placed under the data under the directory "/var/named", and the name is master.rootbug.com. zone. Pay attention to the semicolon ";" When configuring the domain.
Zone "rootbug.com" IN {
Type master;
File "data/master.rootbug.com. zone ";
};

Save and exit after configuration.

(3) create a data file for master.rootbug.com. zone.
[Root @ rootbug ~] # Vim/var/named/data/master.cluster.com. zone

"Remember to add some, you can also write the Internet domain name of the DNS server; and here you can write multiple NS, representing multiple DNS servers in your company.

Dns in a 172.16.2.151
Bbs in a 2.2.2.2

 

Save and exit

(4) Start the DNS server
[Root @ rootbug ~] #/Etc/init. d/named start ---- it takes some time to start the first configuration.

(5) Whether the client authenticates the DNS server correctly
Windows Client Authentication
Enter 172.16.2.151 in the IP Address Configuration DNS column.
