在對mysql數據庫進行操作的時候裸删，報了如下錯誤
mysql> set password for root@localhost = password('123456');
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
解決辦法，刷新一下權限表
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> set password for root@localhost = password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
