Mengapa MySQL tidak dapat terhubung ke host lokal?

biasanya berarti tidak ada server MySQL yang berjalan di sistem atau Anda menggunakan nama file soket Unix atau nomor port TCP/IP yang salah when trying to connect to the server. You should also check that the TCP/IP port you are using has not been blocked by a firewall or port blocking service.
