How to configure name servers for Linux CentOS

To define your nameservers in CentOS you need to edit the resolv.conf file with your favorite text editor:

#    vi /etc/resolv.conf

Add your nameservers as follows and save, for example Google's name servers are:

#    vi /etc/resolv.conf

      nameserver 8.8.8.8
      nameserver 8.8.4.4

Note: Max. three nameservers can be used/defined at a time.
