I will be hosting my site on a Ubuntu 14.04 OS on my droplet.
I will also be hosting my mail server later.( I'll be using gmail for business actually.
Some say that your hostname should be Fully Qualified Domain Name ...
I have installed Apache, Mysql, Webmin & also configured DNS settings for the primary domain but however I want to create a staging site first .i.e. staging.domain.com and then want to make the site live.
