If you have root-level access to a hosting server, this means that you'll have full control of it. That is to say, you can install any server-side application irrespective of the changes that it'll make to the software environment on your server, and you will be able to both access and update any kind of file, including system files, and change any settings. This can be done by connecting to the server as a root user that has full privileges to perform all these things and also to generate other users, including users who also have full privileges. The connection can be established through a web-based graphical interface or a Secure Shell console. For security reasons, it's recommended that you make one more user for your daily work and employ the root user only when you have to modify the server or to set up software which may be needed by some script-driven app that you wish to run.
Full Root-level Access in VPS Hosting
You will be able to take care of your new virtual private servers at the root level regardless of the plan that you have chosen, as long as the server is ordered with either the cPanel or the DirectAdmin web hosting Control Panel, or devoid of Control Panel at all. In the first case, multiple system settings can be managed through an easy to work with web-based interface, whereas in the second, you will need to do everything using a console, unless you decide to install a Control Panel yourself. In either case, you will have full control over the VPS in addition to any kind of system or custom content on it at all times, which makes this kind of web hosting perfect for any app which you can't run with a shared web hosting account because of the restricted level of access - frameworks, VoIP and audio/video streaming software, etc. The final VPS Control Panel option is Hepsia, yet the root access to your server is restricted.
Full Root-level Access in Dedicated Web Hosting
You'll have full root-level access to your dedicated server whatever the package you pick throughout the registration process, as long as the server is ordered with cPanel or DirectAdmin, or without website hosting Control Panel at all. In all of these three cases, you will be able to modify any part of the software environment in any way you see fit, that makes our server plans perfect for multi-media applications with specific requirements that can't be covered if you use a shared hosting account. The main difference between these options is that when you choose cPanel or DirectAdmin, you'll have a web-based graphical interface to control a variety of server-side options and also any web content which you generate or upload, whereas when you order the server with no Control Panel, you'll have to perform everything using a Secure Shell console or to install a Control Panel of your own liking, provided that it is compatible with the OS that you have chosen throughout the sign up process. With the last Control Panel option that you'll be able to select on the order page - Hepsia, the root access will be limited.
