When you have root-level access to a hosting server, it indicates that you will have full control over it. In other words, you can install any server-side app irrespective of the changes that it will make to the software environment on your server, and you're able to both access and customize any file, including system files, and change various settings. This can be done by connecting to the server as a root user which has full privileges to do the aforementioned things as well as to create other users, which includes users who also have full privileges. The connection can be established through a web-based graphical interface or a Secure Shell console. For safety reasons, it's recommended that you make another user for your daily work and use the root user only when you need to customize the server or to set up software that may be needed by a script-driven application that you want to run.
Full Root-level Access in Dedicated Servers
If you pick the cPanel or the DirectAdmin web hosting Control Panel, you will have full root access to your new dedicated server, no matter which of our packages you'll select during the registration process. The very same is valid when you choose not to install a Control Panel at all. Our servers provide you with the chance to run both very resource-demanding apps that are too heavy for a shared website hosting account and applications that have specific requirements as to what the program environment on your server needs to be. The latter is something that can't be achieved on a shared machine, because no server-side software can be set up on it. The difference between the abovementioned solutions is that without a Control Panel, server management can be done only from a console, whereas if you acquire cPanel or DirectAdmin, the majority of system settings along with your site content will be controlled through a graphical interface. If you select Hepsia, which is the last Control Panel option on the registration page, you will get a server with restricted root access.
