To delete a user:

Using Userdel username to delete the user, first Su root into the super user, and then Userdel username, the Userdel:user pxl is currently logged in the hint, the result is unable to delete, So I used Userdel-r-f username, forcing the deletion of all files related to this user, including home directories and user mailboxes, Userdel-r username Delete all files related to this user, and Userdel username Delete account and group information , home directories and user mailboxes are still in, the user I just created does not have a mailbox. Switch User pxl again no more, delete complete.
