Remove a MySQL User
To remove a user from MySQL, we again use the DROP command.

It only takes one simple command to delete a user in MySQL, but BEWARE; dropping a user can not be undone! The command is as follows:

</p>
<p>mysql&gt; DROP USER 'testuser'@'localhost';</p>
<p>

If a user of the name testuser does not exist, then you’ll receive this error:

</p>
<p>mysql&gt; ERROR 1396 (HY000): Operation DROP USER failed for 'testuser'@'localhost'</p>
