If you have root-level access to a server, this means that you'll have full control over it. That is to say, you can install any server-side app no matter what the changes that it will make to the software environment on your server, and you'll be able to both access and modify any kind of file, including system files, and change any settings. You can do this by connecting to the server as a root user who has full privileges to perform all these things and also to create other users, which includes users that also have full privileges. The connection can be established using a web-based graphical interface or a Secure Shell console. For security reasons, it is recommended that you make a different user for your everyday work and use the root user only when you have to customize the server or to set up software which may be required by some script-driven application that you wish to run.
Full Root-level Access in Dedicated Servers
When you select the cPanel or the DirectAdmin hosting Control Panel, you'll have full root access to your new dedicated server, no matter which of our packages you'll choose during the signup process. The same is valid when you decide not to get a Control Panel at all. Our servers will give you the possibility to run both really resource-demanding applications which are too heavy for a shared web hosting account and applications that have specific requirements as to what the program environment on the website hosting server needs to be. The latter is something that can't be achieved on a shared machine, as no server-side software can be set up on it. The difference between the aforementioned choices is that without a Control Panel, server management can be done only from a console, while if you acquire cPanel or DirectAdmin, the majority of system settings and your site content can be managed through a graphical interface. When you pick Hepsia, that is the last Control Panel option on the registration page, you will have a server with restricted root access.
