我试图创建我的第一个数据库，但出现错误

Question

I just started learning MySql for Python on W3Schools. I copied the code that was given as an example and I run it in IDLE, but I got an error.

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="myusername",
  passwd="mypassword"
)

mycursor = mydb.cursor()

mycursor.execute("CREATE DATABASE mydatabase")

Here is the full traceback:

  File "C:\Users\risto\AppData\Local\Programs\Python\Python37-32\lib\site-packages\mysql\connector\network.py", line 509, in open_connection
    self.sock.connect(sockaddr)
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

During handling of the above exception, another exception occurred:

mysql.connector.errors.InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (10061 No connection could be made because the target machine actively refused it)

Can someone help me?

Answer 1

the service about MySQL is not running, or filtered by some firewall rule.
