Can't run the server on Django (connection refused)

Question

I finally (think) installed successfully PostgreSQL and also de psycopg2 (I use Windows). Btw, is some way to check it's working properly?

Well, the thing now is that I can't start the server, while I type 'python manage.py runserver' it shows this (at the end of the command):

conn = _connect(dsn, connection_factory=connection_factory, async=async) django.db.utils.OperationalError: could not connect to server: Connection refused (0x0000274D/10061)     Is the server running on host "localhost" (::1) and accepting     TCP/IP connections on port 8000? could not connect to server: Connection refused (0x0000274D/10061)     Is the server running on host "localhost" (127.0.0.1) and accepting     TCP/IP connections on port 8000? 

I've searched a lot of documentation about it, for example in this topic, but I can't find the way to make it work properly. I've tried several changes in the pg_hba and postgresql files, but with no exit. In this moment, pg_hba looks like:

# TYPE  DATABASE        USER            ADDRESS                 METHOD  # IPv4 local connections: host    all             all             127.0.0.1            md5 # IPv6 local connections: host    all             all             127.0.0.1            md5 # Allow replication connections from localhost, by a user with the # replication privilege. #host    replication     postgres        127.0.0.1/32            md5 #host    replication     postgres        ::1/128                 md5 

And postgresql conf looks like:

# - Connection Settings -  listen_addresses = 'localhost'      # what IP address(es) to listen on;                 # comma-separated list of addresses;                 # defaults to 'localhost'; use '*' for all                 # (change requires restart) port = 8000             # (change requires restart) max_connections = 100           # (change requires restart) # Note:  Increasing max_connections costs ~400 bytes of shared memory per # connection slot, plus lock space (see max_locks_per_transaction). #superuser_reserved_connections = 3 # (change requires restart) #unix_socket_directories = ''   # comma-separated list of directories                 # (change requires restart) #unix_socket_group = ''         # (change requires restart) #unix_socket_permissions = 0777     # begin with 0 to use octal notation                 # (change requires restart) #bonjour = off              # advertise server via Bonjour                 # (change requires restart) #bonjour_name = ''          # defaults to the computer name 

Btw, my settings.py of the database look like this:

DATABASES = { 'default': {     'ENGINE': 'django.db.backends.postgresql_psycopg2',     'NAME': 'database1',                           'USER': 'root',     'PASSWORD': '123456',     'HOST': 'localhost',     'PORT': '8000',     } } 

I haven't created a database BTW, how should I do it? What are the applications of the PostgreSQL prompt?

I would highly appreciate help with this issue I've been days searching and trying but with no exit. Thank you very much.

EDIT 1: I tried changing the settings.py port to 5432, but now the error message is the same, just changing the port:

could not connect to server: Connection refused (0x0000274D/10061)     Is the server running on host "localhost" (127.0.0.1) and accepting     TCP/IP connections on port 5432? 

The config files are right this way? Should I change something? I can't find an answer. I tried with python manage.py runserver and both indicating the 127.0.0.1:8000 and 8001, but no changes in the error message. What's going wrong? Thank you very much.

Answer 1

For me it was for postgres not being started and enabled. So I solved the problem by doing so:

sudo systemctl start postgresql sudo systemctl enable postgresql 

Answer 2

Make port default to 5432

DATABASES = { 'default': {     'ENGINE': 'django.db.backends.postgresql_psycopg2',     'NAME': 'database1',                           'USER': 'root',     'PASSWORD': '123456',     'HOST': 'localhost',     'PORT': '5432',     } } 

run the command:

python manage.py runserver 127.0.0.1:8000
