How to add Primary and Secondary DNS server - /etc/resolve.conf - Linux

Just finished installed CentOS 5. but it can’t recognize any domain. Finally, found out i haven’t add any domain name server (DNS) in my machine. Below is the steps to add domain name server (DNS) in your machine using /etc/resolve.conf file:-

Open file /etc/resolve.conf
You should see something like this:-

search localhost.localdomain

Add your Primary and Secondary Domain Name server (DNS) ip at the end of the file and it should look like this:-

search localhost.localdomain
nameserver 888.888.888.888
nameserver 888.888.888.999
Save the file and exit
Done! you just added primary and secondary dns server in your machine.
To check if your machine works fine, type ping techiecorner.com. If it has reply means your machine work well. If it show unknown host then your configuration has something wrong. Check and rectify it.
