Add Root Password Mysql Nginx Ubuntu 16.04
What is a root password?
In the context of computer security, a root password is a user account that is given access to and control over all of the resources operated by an operating system. This includes the entire file system, the user database, all security features, the hardware itself (with the right information), and so on. The root password is also referred to as the Administrator password or Superuser (SU) password, depending on the operating system.
Root passwords are used to protect a computer from unauthorized access and to restrict access to certain areas of a system, including system files. Root passwords are generally considered more secure than typical user or “service” accounts, since they usually come with more comprehensive rights and privileges, such as the ability to create, modify, and delete files and directories. Furthermore, root passwords are generally changed more frequently than user or service passwords, since they offer a more direct route into a system.
Why do we need a root password?
A root password is required to make changes to system files, create accounts, and to perform system-level maintenance tasks. It is the most secure access point for any system and should be used only when necessary. The root password should be changed frequently, in order to ensure the security of the system.
For example, when updating system software, running system diagnostics, or making changes to system configurations, you must know and enter the root password. Without the root password, these activities cannot be performed, and so it is essential that the root password is known and kept secure.
