I could use some help figuring out what's the problem with running the development server for one of my django projects. When I run python managy.py runserver, I get an error that ends with this:

OperationalError: could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?

Never before has anything like this happened to me while working with Django, so I will be very thankful for every possible solution.

Sounds like you are using Postgresql database and it(database) is not answering

In the settings.py, search for this code and make sure if it is correct:

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3',
    'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
   }
}

And Then start postgresql database service: 

systemctl start postgresql
systemctl enable postgresql
systemctl status postgresql  # Check if it is running correctly.

UPDATE: If you are familiar with databases, then its better to setup a database server of your own and use credentials to login. 

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'databasename',
    'USER': 'databaseuser',
    'PASSWORD': 'userpassword',
    'HOST' : 'localhost',
    'PORT': '',
     }
}

  • If `postgresql` throws back an error about something like *not found* or *not in directory*. Make sure if it is on your system: `sudo apt-get install postgresql postgresql-contrib` – Shameer Kashif Mar 16 '18 at 04:05
