ERROR 1045 (28000): Access denied for user root'@'localhost' (using password: NO

回答: 当你启动数据库时，出现了ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)的错误。这个错误通常是由于没有正确的用户名和密码所引起的。如果你很久没有使用这台电脑的MySQL，可能忘记了用户名和密码。解决这个问题的方法是使用正确的用户名和密码进行登录。如果你在终端上使用默认密码登录出现了类似的错误，可能是由于密码不正确所导致的。你可以尝试使用正确的密码登录。<em>1</em><em>2</em><em>3</em>
