If you have root-level access to a server, it indicates that you will have full control over it. That is to say, you can install any server-side app no matter what the changes that it'll make to the software setting on your server, and you are able to both access and customize any file, including system files, and modify any settings. This can be done by connecting to the server as a root user that has full privileges to do all these things and also to make other users, including users who also have full privileges. This connection can be established with a web-based graphical interface or a Secure Shell console. For security reasons, it's recommended that you create another 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 Servers
When you select the cPanel or the DirectAdmin website hosting Control Panel, you'll have full root access to your new dedicated server, no matter which of our plans you'll pick during the registration process. Exactly the same is valid when you decide not to get a Control Panel at all. All of our servers provide you with the opportunity to run both really resource-demanding applications that are too heavy for a standard shared hosting account and apps which have particular requirements as to what the program environment on the 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 installed on it. The difference between the abovementioned choices is that without having a Control Panel, server management can be done only via a console, whereas if you obtain cPanel or DirectAdmin, most of the system settings and your web content will be managed through a graphical interface. If you choose Hepsia, which is the last Control Panel option on the registration page, you will have a server with limited root access.
