Python MySQL connection. Running on a Virtual Machine

Question

I am trying to establish a connection to MySQL that is running locally using python. i use the following code

import MySQLdb
db = MySQLdb.connect("localhost","username","password","dbname")

I am working on a virtual machine and I am running both the Python and MySQL on the VM. I am not able to make a connection.

I get this errror

OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

I have tried providing the ip address of the VM in place of localhost and still didn't work. I tried specifying the port number too. Is the connection different because it runs on a VM??

Answer 1

When you try to connect directly to mysql Database from command line does it work?

What OS is your VM running? If its a Unix then is there a mysqld process runnning?

In any case this may not have anything to do with Python. Your code snipppet looks ok. You just need to resolve the connectivity issue. Look at this page for details on how you could get to to the root of this problem.

I hope that this helps.

Assuming your client and mysql server on same machine as you said and mysql server is running you can try following

In your my.cnf which would be mostly in /etc/mysql/my.cnf in linux or check with your mysql installation on windows to find my.cnf

look for bind-address directive and set IP address to your VM host.If on linux you can see your VM ip using ifconfig or ipconfig on windows

you may also try commenting out skip-networking line if not already to allow remote clients

Restart mysqld

/etc/init.d/mysqld restart on debian based distros, service mysqld restart for Redhat or restart mysql service on windows
