mysql SELECT/UPDATE command denied to user 'root'@'localhost' for table 'XXX' 报错1142处理

该问题是因为root没有select权限引起的。

解决：赋予root权限

参考原文：https://www.cnblogs.com/owenma/p/7073297.html

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

-------在输入命令进行操作时报错，把 Create_tablespace_priv = 'Y’去掉解决

9.更新一下：

flush privileges;

10.然后重新启动下mysql，可以解决问题了
