无法通过python连接mysql

Question

I did a python -m pip install mysql-connector and able to successfully run import mysql.connector through python. But when I am trying to run the below code.

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword"
)

print(mydb)

It is failing with InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (10061 No connection could be made because the target machine actively refused it)

Since I did pip install for mysql.connector I am not sure of user and passwd.

Answer 1

I connected my database instance from Amazon RDS to mySql workbench, created a python file that looks like his and got the exact error. Everyone says you could have a system firewall problem but nothing straight forward.

Answer 2

The connector is just a means of communicating with a mysql database programically.

You need this, or access to a mysql server to use the connector. https://dev.mysql.com/downloads/mysql/

The host is obviously localhost when you want to access it locally on your machine. This only works if the server is running on your machine. You can connect a remote server by changing the host to a valid IP address and providing valid credentials. If you use it remotely make sure the server has access through the firewall and that you properly forward the TCP port you decide to use. You may not have to forward, but I would as a general rule of thumb to make it one less thing to check when troubleshooting.

Good luck
