ＭySQL默认长链接只能保持8小时，超过后就会自动断开。

peewee报错：

OperationalError: (2006, ‘MySQL server has gone away’)

在peewee中如何维持长连接，可以如下操作：

from peewee import MySQLDatabase
from playhouse.shortcuts import RetryOperationalError

class RetryMySQLDatabase(RetryOperationalError, MySQLDatabase):
    pass

db = RetryMySQLDatabase(
    host='127.0.0.1',
    database='dataname',
    user="root",
    passwd="123456",
    charset='utf8'
)
