如何修复：mysql异常。OperationalError：1045，“用户'root'@'192.168.1.7'的访问被拒绝（使用密码：是）”

Question

Am使用Raspberry Pi 3记录室温，记录的温度必须发送到我的系统，并且应该存储在mysql数据库中。但是无法远程访问mysql。

我确实授予了所有特权并评论了盲人地址

操作系统：ubuntu 18.04

感谢您的帮助

def main():

        while True:

                temperature = sensor.get_temperature()
                print("The temperature is %s celsius" % temperature)
                time.sleep(1)

                #Code to write the recorded temperature in the MYSQL 
                #database 'templog' and table 'temp-at-interrupt'

                db = MySQLdb.connect(host="192.168.1.6", user="root", 
                passwd="root", db="templog")

                cur = db.cursor()
                print("connected to db")

The temperature is 30.625 celsius
