mysql提⽰gottimeoutreadingcommunicationpackets的解
决⽅法
错误提⽰:

MYSQL server has gone away
引起这个原因是不可怕的.原因是更改了系统的断开时间.

interactive_timeout 的黓认值为28800
wait_timeout 的默认值这:120
根据情况增加吧.
这两个值是⼀个全局变量,可以动态增加,如:
mysql> set global interactive_timeout=28800;
Query OK, 0 rows affected (0.00 sec)
mysql> show global variables like "interactive_timeout";

安卓属于linux系统吗| Variable_name | Value |
+---------------------+-------+
| interactive_timeout | 28800 |

1 row in set (0.00 sec)
可以导致Got timeout reading communication packets错误的原因
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)
scanf用法go语言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)
