How to assign root user management permissions to Ubuntu

Article Title: how to assign root user management permissions to Ubuntu. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Ubuntu has a distinctive feature, that is, when you use it for the first time, you cannot log on to the system as the root user. Why? This should begin with the installation of the system. For other Linux systems, the root password is usually set during the installation process, so that the user can use it to log on to the root account or use the su command to convert to the Super User identity. In contrast, Ubuntu does not set a password for the root user or enable the root account when it is installed by default. The problem is, what should I do if I want to run the command as a root user? It doesn't matter. We can use the sudo command for this purpose.

Sudo is a common tool in linux that allows common users to use superuser permissions. This command provides the Administrator with a fine-grained access control method, through it, people can access the system both as Super Users and as other types of users. The advantage of this is that administrators can grant some specific types of Super User Permissions without telling the user the root password, which is what many system administrators dream.

It's easy to set the allocation. Just set a root password for the root user: $ sudo passwd root

You will be prompted to enter the root user password, enter the root password continuously, and then use: $ su

You can switch to the super administrator user to log on!
