在使用mysql 5.5.58-0ubuntu0.14.04.1的Ubuntu 14.04中尝试连接到mysql时：
mysql -u root -h 127.0.0.1
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)
虽然如果我没有主机连接它可以正常工作：
mysql -u root -h 127.0.0.1
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)
azureuser@host:/var/www/website$ mysql -u root

我需要能够使用127.0.0.1作为主机而不是localhost，任何关于为什么会发生这种情况的想法？
谢谢！
