How to configure RHEL5 DNS, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

RHEL5 is added on the basis of RHEL4. The same improvement of the system also allows more people to apply RHEL5, so this requires RHEL5 to be more powerful in configuration, mainly RHEL5 DNS configuration in service configuration, so here is a detailed introduction to the configuration of DNS in RHEL5:

1.RHEL5 DNS configuration installation

After installation, you will find that the named.conf file cannot be found under / etc/, so create it manually! Note that it is not created in the etc directory

Echo > / var/named/chroot/var/etc/named.conf

Vi named.conf

Edit content:

Options

{

Directory "/ var/named"

}

Zone "."

{

Type hint

File "named.ca"

}

Save and exit!

You can see here that the content is very simple, much less than the named.conf under AS4. Options is used to describe global properties, in which directory is set, and a zone is added to the working directory of the specified server. "." Analysis file named.ca pointing to a root domain to generate a named.ca file, you can first configure an available DNS

2. RHEL5 DNS configuration creation content

Create a resolv.conf DNS parsing file with only nameserver 127.0.0.1

Echo "nameserver 127.0.0.1" > / etc/resolv.conf

Then use instructions to create named.ca

Dig-t NS. > / var/named/chroot/var/named/named.ca

Start the domain name service

Service named start

3.RHEL5 DNS configuration edit file

At this point, we can edit the above resolv.conf file and add other dns to it, such as:

Vi / etc/resolv.conf

Nameserver 127.0.0.1

Nameserver 202.103.24.68

Save and exit!

You can use host www.163.com to test whether it can be parsed

4.RHEL5 DNS configuration completes file editing

Next, let's continue to finish the named.conf file.

The editing content is as follows:

Vi named.conf

Options

{

Directory "/ var/named"

}

Zone "."

{

Type hint

File "named.ca"

}

Zone "xxx.com"

{

Type master

File "xxx.com.zone"

}

Zone "1.168.192.in-addr.arpa"

{

Type master

File "192.168.1.rev"

}

Save and exit!

Now that you have finished editing, you can see that you have added your own domain name and added positive and negative resolution!

5.RHEL5 DNS configuration add the appropriate file

Add the corresponding parsing file

/ var/named/chroot/var/named/xxx.com.zone and / var/named/chroot/var/named/192.168.1.rev

And edit the file:

Vi xxx.com.zone

@ IN SOA rhel5.com. Root (

20060801

1H

15M

1W

1D)

IN NS ns

IN MX 10 mail

Ns IN A 192.168.1.159

Www IN A 192.168.1.159

Mail IN A 192.168.1.159

Save and exit!

Vi 192.168.1.rev

@ IN SOA rhel5.com. Root (

20060801

1H

15M

1W

1D)

IN NS ns.xxx.com.

159 IN PTR ns.xxx.com.

159 IN PTR www.xxx.com.

159 IN PTR mail.xxx.com.

Save and exit!

Note: be sure to use Tab alignment!

Now that the configuration is complete, restart the named service:

Service named restart

Now let's test it:

[root@rhel5 /] # nslookup www.xxx.com

Server: 127.0.0.1

Address: 127.0.0.1#53

Name: www.xxx.com

Address: 192.168.1.159

[root@rhel5 /] # nslookup mail.xxx.com

Server: 127.0.0.1

Address: 127.0.0.1#53

Name: mail.xxx.com

Address: 192.168.1.159

You can see that it can be parsed successfully!

RHEL5 DNS is a little more troublesome than RHEL4 DNS, even if you choose the DNS service when you install the system, you should install the RPM package of bind after entering the system normally, and then install the RPM package of caching-nameserver. The system will install the bind.util package by default, so that the package used by the DNS service will be fully installed.
