If you have root-level access to a hosting server, it indicates that you will have full control over it. That is to say, you can install any server-side app whatever the changes that it'll make to the software setting on the server, and you will be able to both access and customize any kind of file, including system files, and change various settings. You can do this by connecting to the server as a root user that has full privileges to perform the aforementioned things and to make other users, which includes users who 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 different user for your everyday work and use the root user only when you have to modify the server or to install software which may be required by a script-driven app that you would like to run.
Full Root-level Access in VPS
You'll be able to control your new virtual private servers at the root level whatever the plan that you've chosen, as long as the server is ordered with either the cPanel or the DirectAdmin web hosting Control Panel, or without any Control Panel at all. In the first case, multiple system settings can be controlled via an easy to work with web-based interface, whereas in the second, you'll need to do everything via a console, until you decide to set up a Control Panel yourself. In either case, you will have full control over the VPS plus any system and / or custom content on it at all times, that makes this kind of hosting perfect for any app that you can't run with a shared web hosting account due to the limited degree of access - frameworks, VoIP and audio/video streaming software, and so on. The final VPS Control Panel option is Hepsia, yet the root access to your server will be restricted.
Full Root-level Access in Dedicated Hosting
In case you pick the cPanel or the DirectAdmin website hosting Control Panel, you will have full root access to your new dedicated server, regardless of which of our packages you'll select during the signup process. The same is valid when you choose not to add a Control Panel at all. All of our servers will provide you with the option to run both really resource-demanding apps that are too heavy for a standard shared website hosting account and applications that have certain requirements as to what the software environment on the server has to be. The latter is something which can't be achieved on a shared machine, because no server-side software can be set up on it. The difference between the aforementioned solutions is that without having a Control Panel, server management can be done only from a console, while if you acquire cPanel or DirectAdmin, the majority of system settings along with your website content can be controlled through a graphical interface. If you choose Hepsia, which is the last Control Panel option on the registration page, you'll receive a server with restricted root access.
