[MySQL] ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/usr/local/MYSQL/var/lib/mysql/mysql.sock' (2)

今天使用了以下指令無法要登進去mysql時噴出了錯誤

mysql -h 127.0.0.1 -u root -ppassword

錯誤訊息
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/usr/local/MYSQL/var/lib/mysql/mysql.sock' (2)

結果加個-h參數就正常了XD，真奇怪
mysql -h 127.0.0.1 -u root -ppassword
