mysql error: [1045: Access denied for user: 'linpha_0GnF@localhost' (Using password: YES)] in CONNECT(localhost:, '****', '****', demo_demo)
Access denied for user: 'linpha_0GnF@localhost' (Using password: YES)

mysql>
SET PASSWORD FOR 'root'@'localhost' = OLD_PASSWORD('123456');

假如是新装的mysql，确定执行过类似以上的命令了吗？
