I got a simple Django 1.3.* project, i would like to run it over my localhost.
I installed all necessary modules like: python-mysqldb, rptz etc...
I have ubuntu 10.04 installed with python 2.7.2.
When i tried to start project in terminal

thor@thor:/media/SAJAT - Projects/project/simple project$ python manage.py runserver

I got the following error message:

> Validating models...

_mysql_exceptions.OperationalError: (2003, "Can't connect to MySQL server on '172.17.30.101' (110)")

I have no idea where this IP address comes from 172.17.30.101' (110) because of my mysql server has been installed on my computer(localhost)

Here is my settings.py file

 DATABASES = 
 'default': 
 'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
 'NAME': 'dbname', # Or path to database file if using sqlite3.
 'USER': 'dbuser', # Not used with sqlite3.
 'PASSWORD': '123456', # Not used with sqlite3.
 'HOST': '127.0.0.1', # Set to empty string for localhost. Not used with sqlite3.
 'PORT': '', # Set to empty string for default. Not used with sqlite3.
 #'PORT': '3306', i tried with this too # Set to empty string for default. Not used with sqlite3.
 #'PORT': '3360', i tried with this too # Set to empty string for default. Not used with sqlite3.

I have no idea how should be resolve this kind of errors.

First and foremost Django 1.3 has been unsupported for over a year (since 1.5's release, Feb 2013). You should consider it dangerous to leave in public-facing circumstances. Ubuntu 10.04 Server will reach that state in less than a year too... So besides your actual problem, you need to consider a infrastructure upgrade.

That your site is connecting to a random-looking reserved (it's not a legal public IP) on the standard POP3 port. I can't see any circumstance where this could happen accidentally. Something in your setup is causing this to happen.

My money's on your settings, like another definition of DATABASES that you haven't noticed. Confirm this by adding this to one of your views:

from django.conf import settings
print settings['DATABASES']

And see what comes out the other side. From there it's just finding the problem.

Failing that

• Check that old DATABASE_* settings aren't interfering in a similar method


• Trace the connection back through the MySQL module code. You can see what's going on in your trace. Track that back (inserting print statements if you have to) until you get to the point where your connection is being formed.
