Flask-SQLAlchemy PyMySQL - Access Denied Error

问题:

OS: RHEL Python Version: 3.6 SQLAlchemy Version: 1.1.10 PyMySQL Version: 0.7.11 MySQL Distrib: 5.7.17-13

import pymysql  conn = pymysql.connect(host='localhost', port=3306, user='testuser', passwd='###########', db='mysql')  cur = conn.cursor()  cur.execute("SELECT Host,User FROM user")  print(cur.description)  print()  for row in cur:     print(row)  cur.close() conn.close() 

When I try to execute the above code I'm getting the following error message, but I'm still able to connect to mysql using the same account and password via command line.

pymysql.err.OperationalError: (1045, "Access denied for user 'testuser'@'127.0.0.1' (using password: YES)") 

I tried searching all over the internet for this error message but I could not figure out the actual issue. I would really appreciate if anyone could help me fix this issue.

I found the issue: The default auth plugin for MySQL 5.7 was sha256 which is not supported by PyMySQL. Changed it to mysql_native_password and that fixed the issue.
