Centos tutorial 2: add an operator account

Because the root user has full operation permissions on the system, in order to avoid some mistakes, we recommend that you log on to the system as a general user. If necessary, you need root operation permissions, then, run the "Su-" command to log on as the root user.

 

1. Create an amonest account:

 
[Root @ localhost ~] # Useradd amonest
 

 

2. Set the amonest password:

 
[Root @ localhost ~] #PasswdAmonestchanging PasswordForUser amonest. New Password: # enter the password. retype new password: # enter the password again.Passwd: All authentication tokens updated successfully.
 

 

3. Add the amonest account to the wheel group.

 
[Root @ localhost ~] # Usermod-G wheel amonest
 

 

4. ConfigurationOnly the user in the wheel group can run the "Su-" command to log on as the root user. Users in other groups can run the "Su-" command and enter the correct root password, you cannot log on as the root user. OpenIn the/etc/PAM. d/su file, locate the following line, remove the comment and save it:

 
# Auth required pam_wheel.so use_uid
 

Then run the following command:

 
[Root @ localhost ~] #Echo "Su_wheel_only Yes">/Etc/Login. Defs
 

 

OK. Now you can log out of root and use amonest to log on. Run the "Su-" command when the root permission is required.
