Connecting to MySQL database via SSH

Question

I am trying to connect my python program to a remote MySQL Database via SSH.

I am using Paramiko for SSH and SQLAlchemy.

Here is what I have so far:

import paramiko
from sqlalchemy import create_engine

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('host', port=port, username='user', password='pass')

engine = create_engine('mysql+mysqldb://user:pass@host/db')

I am getting an error:

sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (2003, "Can't connect to MySQL server on 'mcsdev.croft-it.com' (60)")

Sorry I posted a duplicated answer before. Here is a more elaborated answer tailored exactly to your question ;)

If you still in need of connecting to a remote MySQL db via SSH I have used a library named sshtunnel, that wraps ands simplifies the use of paramiko (a dependency of the sshtunnel).

With this code I think you will be good to go:

from sshtunnel import SSHTunnelForwarder
from sqlalchemy import create_engine

server =  SSHTunnelForwarder(
     ('host', 22),
     ssh_password="password",
     ssh_username="username",
     remote_bind_address=('127.0.0.1', 3306))

server.start()

engine = create_engine('mysql+mysqldb://user:pass@127.0.0.1:%s/db' % server.local_bind_port)

# DO YOUR THINGS

server.stop()
