Access denied for user 'root'@'127.0.0.1' (using password: YES)

这个错误提示是因为在使用Navicat连接MySQL时，使用的用户名为root，密码为YES，但是被拒绝了。这个问题可能有几种原因。首先，根据引用\[1\]和引用\[2\]，可能是因为在连接MySQL时输入的密码不正确。你可以尝试重新输入密码，确保密码的正确性。其次，根据引用\[3\]，可能是因为在连接MySQL时使用的是127.0.0.1而不是localhost。在MySQL中，使用127.0.0.1是通过TCP/IP协议连接到本机的，而使用localhost是通过Unix Socket连接到本机的。你可以尝试在my.cnf的\[mysql\]区域里设置protocol=tcp，来默认选择TCP/IP的连接方式，或者为localhost设置一个密码。希望这些解决方法能够帮助你解决问题。
