MySQL bug整理

整理了一些遇到过的报错信息

1. 远程连接服务器数据库报错：

   Host ‘XXXXXX’ is blocked because of many connection errors. 

   Sol:

   show global variables like ‘%max_connect_errors%';
   set global max_connect_errors=1000000;

   但是这不是问题的根本解决方法，只能一时有效，永久有效可参考以下文章：

2. 跟权限相关的报错

   ERROR 1290 (HY000): The MySQL server is running with the —skip-grant-tables option so it cannot execute this statement. 

   Sol:

   刷新权限列表 flush privileges;
   赋予权限：grant all privileges on . to USER@'%'identified by 'password';

3. SQL语句过长导致执行失败
   Sol:

   更改最大限制

   set global max_allowed_packet = 6*1024*1024;
