(2003, "Can't connect to MySQL server on '192.168.60.172' (99)")错误

mysql连上一段时间连不上报错了,

(2003, "Can't connect to MySQL server on '192.168.60.172' (99)")

此类错误是连接数超过设定的限制引起

检查到代码如下:

class PathProperty(object):
    def __init__(self,place, path=''):
        self.path = path
        self.place = place
        self.mysqldb = mysql_connect()

    def get_state(self):
        quary_sql = 'select state from cmdb_test.path_info_history where path= \'{}\' and site=\'{}\''.format(self.path,self.place)
        con = self.mysqldb.select(quary_sql)
        data = con.fetchone()
        return data[0]

    def get_path(self):
        quary_sql = 'select path from cmdb_test.path_info_history where site=\'{}\''.format(self.place)
        con = self.mysqldb.select(quary_sql)
        data = con.fetchone()
        return data[0]

    def get_company(self,):
        quary_sql = 'select company from cmdb_test.path_info_history where path= \'{}\' and site=\'{}\''.format(self.path, self.place)
        con = self.mysqldb.select(quary_sql)
        data = con.fetchone()
        return data[0]

此类中在初始化进行了连接mysql动作,导致多次实例化类,造车循环中多次链接.

由此,在类__init__加动作操作时危险的.
