Configure DNS in RHEL5: My version is 5.3

Install bind-9.3.4-10.P1.el5.x86_64.rpm

Bind-chroot-9.3.4-10.P1.el5.x86_64.rpm

Bind-libs-9.3.4-10.P1.el5.i386.rpm

These packages can be found on the RHEL installation disk.

1. Install RHEL5 DNS Configuration
After installation, you will find that the named. conf file cannot be found under/etc/. You need to create it manually !! Note that it is not created in the etc directory,
Echo>/var/named/chroot/etc/named. conf

Vi named. conf

Edit content:
Options
{
Directory "/var/named ";
};
Zone "."
{
Type hint;
File "named. ca ";
};

Save and exit!

Here we can see that the content is very simple, compared with the named in as4. the conf content is much less. options is used to describe the global attributes, where directory is set and a zone is added to the working directory of the specified server ". "The analysis file named pointing to a root domain. ca must generate a named. you can configure an available DNS for the ca file first.

2. RHEL5 DNS Configuration Creation content
Create a resolv. conf DNS resolution file with only nameserver 127.0.0.1
Echo "nameserver 127.0.0.1">/etc/resolv. conf
Then use the command to create named. ca
Dig-t NS.>/var/named/chroot/var/named. ca
Start Domain Name Service
Service named start

3. RHEL5 DNS configuration editing File
In this case, you can edit the above resolv. conf file, and then add other dns such:
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 DNS resolution can be performed.

Now, the local machine can use the dns Service normally.

4. RHEL5 DNS configuration completes file editing
Next, complete the named. conf file.
The Edit 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!
The editing is complete. You can see that you have added your domain name and added a forward/reverse resolution!
