我試圖創建我的第一個數據庫，但出現錯誤

Question

我剛開始在 W3Schools 上為 Python 學習 MySql。 我復制了作為示例給出的代碼並在 IDLE 中運行它，但出現錯誤。

import mysql.connector

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

mycursor = mydb.cursor()

mycursor.execute("CREATE DATABASE mydatabase")

這是完整的回溯：

  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:

Traceback (most recent call last):
  File "C:/Users/risto/AppData/Local/Programs/Python/Python37-32/mysql1.py", line 6, in <module>
    passwd="mypassword"

    return MySQLConnection(*args, **kwargs)

    self._socket.open_connection()
  File "C:\Users\risto\AppData\Local\Programs\Python\Python37-32\lib\site-packages\mysql\connector\network.py", line 512, in open_connection
    errno=2003, values=(self.get_address(), _strioerror(err)))
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)

有人能幫我嗎？

關於 MySQL 的服務未運行，或被某些防火牆規則過濾。
