Here’s how to use your dual IP address equipment Network Presence VPS running the CentOS flavour of Redhat Linux, to run your Name Servers (ns1 and ns2) for your own Domains.<\/p>\n
First, you need two separate live to the Internet IPv4 IP Addresses and if you’re VPS Plan is one of our popular Value VPS Plans, then you only have a single IP address to start. So our “Extra IP Address for your VPS<\/a>” Professional Services product provides you with another IP address that can be configured to your CentOS VPS.<\/p>\n If you need to configure another IP address to your CentOS VPS, then replace X.X.X.X and Y with details supplied by us in the following shell command extract (run as the ‘root’ user when logged into your VPS by SSH client) :<\/p>\n ifup eth0:0 ## or reboot now..<\/code><\/p>\n Then with your dual IP Addresses running on your VPS, you can now install the BIND\/named Name Server packages for CentOS with:<\/p>\n This just installs the software, but doesn’t configure it in any way and you next need to populate the various files that BIND Like most RHEL-based RPMs and open-source software distributions, the bind Package has installed example and documentation files into So now we copy relevant example files and then configure your local Name Server for your Domain name and the following creates a named.conf file for you in the “chroot” directory tree of the CentOS “bind-chroot” package. Please substitute YOURDOMAIN.CO for your full domain name.<\/p>\n Now configure your \/etc\/named.conf.local, with a template looking like:<\/p>\n If you have a separate Secondary Name Server, then its named.conf.local file would be (to be a ‘slave’ Name Server from your Primary’s IP address, assuming that the Primary Name Server is on X.X.X.X and the Secondary is on IP addr Y.Y.Y.Y, being the above referenced ‘IP-ADDRESS-OF-YOUR-SECONDARY-NAME-SERVER’:<\/p>\n Make sure that the running Name Server software will be able to read those files with commands like (as root):<\/p>\n Last step in the setup is to create the “Zone Files” (the actual files containing your domain’s data or information) and continuing to use the template\/demo domain name of YOURDOMAIN.CO and your VPS IP Address of X.X.X.X, here’s a template Zone File for YOURDOMAIN.CO:<\/p>\n With the templates and filenames listed above updated for your actual domain names, you can now test that your configuration works with:<\/p>\n If all is “Ok” in that output, now start your Name Server with:<\/p>\n And make sure it’ll start at system bootup with:<\/p>\n That should do it, start testing with the ‘dig’ commands, substituting your actual domain name with something like:<\/p>\n Or from a remote host with:<\/p>\n FYI and Network Presence customers are welcome to contact us<\/a> for help setting up their Name Servers, regards, Here’s how to use your dual IP address equipment Network Presence VPS running the CentOS flavour of Redhat Linux, to run your Name Servers (ns1 and ns2) for your own Domains.
