[MySQL]ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

콘솔에서 root로 접속하려고 할 때 아래와 같은 에러 메시지가 뜨는 경우가 있다.

[root@nyaongnyaong ~] # mysql -uroot -p

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

이런 경우는 위 에러 메시지를 긁어서 네이버나 구글에서 검색해 보는 게 가장 빠르다.
