ERROR 1044 (42000): Access denied for user [email?protected] to database ‘meitu‘

解決方法：

1. 在/etc/my.cnf的[mysqld]字段下加入：skip-grant-tables ， 如下截圖

2. 再重啟mysqld服務

[[email?protected] ~]$ systemctl restart mysqld

這時的mysql不需要密碼即可登錄數據庫

3. 登錄進入mysql，執行以下命令

mysql > use mysql;

mysql > delete from user where USER=‘‘;

mysql > flush privileges;

mysql > exit;

4. 再刪除/etc/my.ini中的skip-grant-tables，重啟mysqld服務即可正常建庫了。
