If you have root-level access to a server, this means that you will have full control over it. That is to say, you can set up any server-side app whatever the changes that it'll make to the software setting on the server, and you're able to both access and change any kind of file, which includes system files, and change any settings. This can be done by connecting to the server as a root user which has full privileges to perform all these things as well as to generate other users, which includes users that also have full privileges. This particular can be established with a web-based graphical interface or a Secure Shell console. For safety reasons, it's recommended that you create a separate user for your daily work and employ the root user only when you need to modify the server or to install software that may be needed by some script-driven application that you would like to run.
Full Root-level Access in Dedicated Hosting
You'll have full root-level access to your dedicated server no matter which plan you pick throughout the registration process, as long as the server is ordered with cPanel or DirectAdmin, or with no web hosting Control Panel at all. In all of these three cases, you're able to modify any part of the software environment in any way you see fit, which makes our server plans suitable for resource-demanding apps with specific requirements which can't be covered when you use a shared website hosting account. The difference between these options is the fact that when you use cPanel or DirectAdmin, you'll have a web-based graphical interface to manage various server-side options as well as any web content that you generate or upload, whereas if you order the server devoid of Control Panel, you will have to perform everything through a Secure Shell console or to set up a Control Panel of your own liking, provided that it is compatible with the OS that you have selected during the registration process. With the third Control Panel option that you'll be able to select on the order page - Hepsia, the root access is restricted.
