MySQL數據庫未連接到Python

Question

我正在嘗試通過此代碼將python連接到mysql-（我正在使用mysql.connect庫）

import mysql.connector

cnx = mysql.connector.connect(user='root', 
                          password='password',
                          host='127.0.0.1',
                          database='db')
print(cnx)
cnx.close()

但是它繼續引發錯誤-

Traceback (most recent call last):

我已經在工作台中啟動了mysql服務器，並且還檢查了狀態。 此外，還存在名為“ db”的數據庫，還檢查主機是否正確。 ->也刪除了ssl。

看來您的MySQL Server版本是8.x，在這種情況下，默認的MySQL連接器是caching_sha2_password 。 另一方面，您的錯誤可能是因為您的python客戶端連接器不支持此身份驗證插件 ，因此您應將身份驗證插件明確更改為舊的（ mysql_native_password ）。

cnx = mysql.connector.connect(user='root', password='password',
                          host='127.0.0.1', database='db',
                          auth_plugin='mysql_native_password')
