【踩坑】Django django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password:

問題背景

Django項目初始化，在MySQL數據庫中創建表報錯

python  manage.py   migrate

報錯如下：

django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password: 

解決過程

• 嘗試1：bind-address = 0.0.0.0
  my.cnf配置文件中注釋掉bind-address = 127.0.0.1，新增配置bind-address = 0.0.0.0，重啟MySQL服務

[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1
bind-address = 0.0.0.0

結果：同樣報錯

• 嘗試2：修改root用戶的權限，刷新權限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
FLUSH PRIVILEGES;

結果：同樣報錯

• 嘗試3：修改root的密碼

mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';

結果：同樣報錯

*** 崩潰的分割線 ***

• 嘗試4：嘗試在本地連接數據庫

import mysql.connector

conn = mysql.connector.connect(host="127.0.0.1",user='root',database='website',password='YourPassword')

# 獲游標標對象

print(conn)

報錯：Authentication method 'caching_sha2_password' is not supported，原因在MySQL 8.X中 caching_sha2_password is the default authentication plugin rather than mysql_native_password.

解決辦法：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourPassword';
FLUSH PRIVILEGES;

結果：問題解決
