1.首先停止mysql服务：service mysqld stop

2.加参数启动mysql：/usr/bin/mysqld_safe --skip-grant-tables &

然后就可以无任何限制的访问mysql了

3.root用户登陆系统：mysql -u root -p mysql

4.切换数据库：use mysql

5.显示所有的表：show tables;

这里就可以访问表了

6.查看user表中root用户的localhost权限：select * from user where user='root' and host='localhost'

7.在显示的列表中显示：root用户的localhost的权限都是'N',表示root用户本地登陆不具有权限

8.修改root用户的localhost权限：

update user set

`Select_priv` = 'Y',

`Insert_priv` = 'Y',

`Update_priv` = 'Y',

`Delete_priv` = 'Y',

`Create_priv` = 'Y',

`Drop_priv` = 'Y',

`Reload_priv` = 'Y',

`Shutdown_priv` = 'Y',

`Process_priv` = 'Y',

`File_priv` = 'Y',

`Grant_priv` = 'Y',

`References_priv` = 'Y',

`Index_priv` = 'Y',

`Alter_priv` = 'Y',

`Show_db_priv` = 'Y',

`Super_priv` = 'Y',

`Create_tmp_table_priv` = 'Y',

`Lock_tables_priv` = 'Y',

`Execute_priv` = 'Y',

`Repl_slave_priv` = 'Y',

`Repl_client_priv` = 'Y',

`Create_view_priv` = 'Y',

`Show_view_priv` = 'Y',

`Create_routine_priv` = 'Y',

`Alter_routine_priv` = 'Y',

`Create_user_priv` = 'Y',

`Event_priv` = 'Y',

`Trigger_priv` = 'Y',

`Create_tablespace_priv` = 'Y'

where user='root' and host='localhost

9.更新一下：flush privileges;

10.然后重新启动下mysql，可以解决问题了
