Python code to establish an ssh to remote server and then connect to MYSQL

问题

I am trying to write some python code to establish an ssh connection to a remote server and then execute some MYSQL queries (I have left these out of the example for simplicity). As far as I can gather the ssh is working but I can't seem to get into the database. Can anyone help?

import MySQLdb
import decimal
import operator
import os
import paramiko



mykey = paramiko.RSAKey.from_private_key_file("C:/Users/Desktop/keyname.pem")

ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('ec2-blah-blah.compute.amazonaws.com', username='ec2-user', pkey = mykey) 

conn = MySQLdb.connect(
    host="127.0.0.1",
    port = 3306,
    user="root",
    passwd="password",
    db="MyDB")

The errors I get are:

File "C:\Python27\lib\site-packages\MySQLdb__init__.py", line 81, in Connect return Connection(*args, **kwargs) File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in in it super(Connection, self).init(*args, **kwargs2) _mysql_exceptions.OperationalError: (2003, "Can't connect to MySQL server on '12 7.0.0.1' (10061)")

回答1:

The ip address "127.0.0.1" that you use in your connection object refers to localhost, which is the computer the program is running on. You can't remotely connect to the localhost of another computer. You need to replace the host ip address with the ip address of the remote server.

Also you should only need the MySQLdb.connect object, not the ssh object if you connect correctly.
