Set up the DNS service in linux and set up the linuxdns Service

Set up the DNS service in linux and set up the linuxdns Service

I will not elaborate on the theoretical knowledge too much here.

Need to Know: http://baike.baidu.com/subview/22276/15346050.htm? Fr = aladdin

Go to build

Software used: Vmware workstation 10 rhel6.3 (64-bit)

Operating system used:

[Root @ wang ~] # Uname-

Linux wang 2.6.32-279. el6.x86 _ 64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

First, mount the image

[Root @ wang ~] # Mount/dev/cdrom/opt/

Then configure yum. By default, the yum package has been installed.

Configure local yum source now

[Root @ wang ~] # Cd/etc/yum. repos. d/

[Root @ wang yum. repos. d] # ls

Rhel-source.repo

[Root @ wang yum. repos. d] # vi rhel-source.repo

Save and exit

Use yum list for testing

[Root @ wang yum. repos. d] # yum list

Use yum to install the main DNS package bind

[Root @ wang yum. repos. d] # yum install bind-*-y

Next, modify the configuration file.

[Root @ wang ~] # Vi/etc/named. conf

Check file correctness

[Root @ wang ~] # Named-checkconf/etc/named. conf

[Root @ wang ~] #

Next we will talk about copying the/var/named file to the chroot directory. chroot is developed as a DNS security consideration and serves as a confusing attacker.

 

[Root @ wang ~] # Cd/var/named/

[Root @ wang named] #

[Root @ wang named] # ls

Chroot data dynamic named. ca named. empty named. localhost named. loopback slaves

[Root @ wang named] #

[Root @ wang named] #

[Root @ wang named] # cp named. */var/named/chroot/var/named/

[Root @ wang named] #

Do not confuse the chroot named directory with the previous one.

[Root @ wang named] # pwd

/Var/named/chroot/var/named

[Root @ wang named] # ls

Named. ca named. empty named. localhost named. loopback

Create forward and reverse DNS resolution files

[Root @ wang named] # cp named. empty wang. zone

[Root @ wang named] #

[Root @ wang named] #

[Root @ wang named] # ls

Named. ca named. empty named. localhost named. loopback wang. zone

[Root @ wang named] #

[Root @ wang named] #

[Root @ wang named] # cp named. empty rewang. zone

Here named. empty is the Template File

Modify forward resolution File

[Root @ wang named] # vi wang. zone

Modify reverse resolution File

[Root @ wang named] # vi rewang. zone

Check whether the configured forward file is faulty.

[Root @ wang named] # named-checkzone wang.com/var/named/chroot/var/named/wang. zone

Zone wang.com/IN: loaded serial 0

OK

[Root @ wang named] #

Change the root group in var to the named group.

Original:

[Root @ wang named] # ll

Total 24

-Rw-r -----. 1 root 1892 Dec 5 12:24 named. ca

-Rw-r -----. 1 root 152 Dec 5 12:24 named. empty

-Rw-r -----. 1 root 152 Dec 5 12:24 named. localhost

-Rw-r -----. 1 root 168 Dec 5 nam24 named. loopback

-Rw-r -----. 1 root 189 Dec 5 12:42 rewang. zone

-Rw-r -----. 1 root 185 Dec 5 12:35 wang. zone

After modification:

[Root @ wang named] # chown-R named/var/named/chroot/

[Root @ wang named] # ll

Total 24

-Rw-r -----. 1 named root 1892 Dec 5 named. ca

-Rw-r -----. 1 named root 152 Dec 5 named. empty

-Rw-r -----. 1 named root 152 Dec 5 named. localhost

-Rw-r -----. 1 named root 168 Dec 5 named. loopback

-Rw-r -----. 1 named root 189 Dec 5 rewang. zone

-Rw-r -----. 1 named root 185 Dec 5 wang. zone

[Root @ wang named] #

Start the service next, but sometimes the following problems may occur:

. Generating/etc/rndc. key: stuck here when DNS is started

[Root @ RedHat named] #/etc/init. d/named restart

Stopping named: [OK]

Generating/etc/rndc. key:

^ C

[Root @ redhat named] #

Solution:

[Root @ redhat named] # rndc-confgen-r/dev/urandom-

Wrote key file "/etc/rndc. key"

[Root @ redhat named] #/etc/init. d/named restart

Stopping named: [OK]

Starting named: [OK]

Next, test

Modify the reslov File

[Root @ wang named] # vi/etc/resolv. conf

Add

Search www.wang.com

Nameserver 10.10.39.183

Save and exit.

Then ping

So far, the DNS master configuration is complete. please correct me if you have any shortcomings.
