This article shows you how to establish general users in the administrator group in the CentOS Linux system. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

In general, the average user can log in as a root user to configure the system at the administrator level by executing the "su -" command and entering the correct root password. However, in order to further strengthen the security of the system, it is necessary to establish a group of administrators, which only allows users of this group to log in as root users by executing the "su -" command, while users of other groups cannot log in as root users even if they execute "su -" and enter the correct root password. Under UNIX, the name of this group is usually "wheel".

[root@sample ~] # usermod-G wheel CentOSpub ← adds the general user CentOSpub to the administrators group wheel group

[root@sample ~] # vi / etc/pam.d/su ← opens this configuration file

# auth required / lib/security/$ISA/pam_wheel.so use_uid ← find this line and remove the "#" at the beginning of the line

↓

Auth required / lib/security/$ISA/pam_wheel.so use_uid ← changes to this state (approximately on line 6)

[root@sample ~] # echo "SU_WHEEL_ONLY yes" > > / etc/login.defs ← add statement to the end of the line

When you are done, you can create a new user, and then use this new user test to find that users who have not joined the wheel group execute the "su -" command and cannot log in as a root user even if they enter the correct root password.
