Question

我在raspberry pi中有代码，它应该将传感器数据发送到windows 7的远程mysql服务器。我已经在raspberry地址中修改了my.cnf文件的bind-address，我也完成了如下设置，

全部取消。''root'@'％'由'mumbai'识别;

FLUSH PRIVILEGES;

我的代码如下，

import MySQLdb
def temp_sensor():
   conn = MySQLdb.connect(host = '192.168.1.103', user = 'root', passwd
       = 'mumbai', db = 'weather', port = 3306)
            cursor = conn.cursor()
  while True:
        try:
             date = time.strftime("%d/%m/%Y")
             temp,humidity,light = main.reading()
             args= ('192.168.1.145', 'b8:27:eb:06:e4:4b', 'Temp_PI', temp)
             cursor.callproc('SPR_IU_Sensor_Data',args)
             conn.commit()
             time.sleep(interval2)
        except MySQLdb.Error,  e:
             print 'Error %d: %s' % (e.args[0], e.args[1])

给出错误，

 Process Process-1:
   Traceback (most recent call last):
    File "/usr/lib/python2.7/multiprocessing/process.py", line 258,
    self.run()
   File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run
