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

People, first of all I have already turned all topics around here and the error in question remains. I have tested several solutions presented here and indexed in google but it will not, since everything I try results in "ERROR 1045 (28000): Access denied for user 'weslei' @ 'localhost' (using password: NO)", the connection will not will not. I uninstalled mysql, I reinstalled and I'm running version 8.0.11 for Linux on i686 (MySQL Community Server - GPL)
