可能导致Got Timeout reading communication packets错误的原因有如下几个：
A client attempts to access a database but has no privileges for it.（没有权限）
A client uses an incorrect password.(密码错误)
A connection packet does not contain the right information.(连接没有包含正确信息)
It takes more than connect_timeout seconds to obtain a connect packet. (获取连接信息起过connect_timeout的时长)
The client program did not call mysql_close() before exiting.(客户端没有调用mysql_close()函数)
The client had been sleeping more than wait_timeout or interactive_timeout seconds without issuing any requests to the server. (客户端的空连接时间过长，超过了wait_timeout和interactive_timeout的时间)
The client program ended abruptly in the middle of a data transfer.(数据传输过程中终结)
