I am having issues connecting to my Postgresql database with my Django website. My database is set up at Port 5434 as there is already an existing database in the default 5432 port.
This is the error I am getting

This is my settings.py file in django
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'database_name',
'USER': 'postgres',
'PASSWORD': '******',
'HOST': 'localhost',
'PORT': '5434',
}
}
Hi, I figured it out. Really stupid mistake. I add two of the Database= {} configuration twice, once at the top of the file and once i the bottom and for got to delete it lol.
This issue is generated for lack of permission.You should give the permission in pg_hba file.
Log into your db user and then play the command psql. The sequensial coammnd is given bellow.
sudo su - postgres
psql
show hba_file;
In my case the output is /var/lib/postgresql/data/pg_hba.conf. Rember this location
\q
ctrl + d # for loging out from postgres user
sudo vim /var/lib/postgresql/data/pg_hba.conf #you can use your prefer text editor
You need to change the file as shown bellow. Just change all method to trust.

Firstly, I'm on Windows 10.
I just started learning Django. I did the tutorials that are with the Django documentation. I need to program an app that uses a PostgreSQL database. This is for a test following up a job interview, so I don't want to mess this up.
When I run the command "python manage.py runserver", I run into the following error :
d:\Utilisateur\Documents\code\code_python\Django\Psycle_test\mysite>python manage.py runserver

Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
The Django documentation says that I need to install psycopg2. Which I did using the command "pip install psycopg2". I configured settings.py in my Django project in order to use a PostgreSQL database :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'myDataBase',
'USER': 'myDataBaseUser',
'PASSWORD': 'password',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
Changing 'ENGINE': 'django.db.backends.postgresql' to 'ENGINE': 'django.db.backends.postgresql_psycopg2' gives me the same error.
I also tried to change '127.0.0.1' to 'localhost' and it still doesn't work.
(The different topics I've seen talk about a postgresql.conf file, but I can't seem to find it anywhere, if it can even solve anything anyway.)
What am I doing wrong?
Edit
After installing PostgreSQL 9.6, creating myDataBase, creating a role myDataBaseUser and granting the privileges to that role, I now get that error:

It seems like you dont have postgres database installed locally. Download it from here
Then going into console you need to create database by create database myDataBase;
create role by create role myDataBaseUser with password 'password'. Grant privileges to the role by
grant all privileges on database "myDataBase" to myDataBaseUser.
Then you will
be able to connect.
In fact, I learn the django from the website:https://docs.djangoproject.com/zh-hans/2.1/intro/tutorial02/
The next is my settting.py
DATABASES = {
# 'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
# }
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_01',
'USER': 'root',
'PASSWORD': '9940',
'HOST': 'localhost', # Or an IP Address that your DB is hosted on
'PORT': '3306',
}
}
mysql :
enter image description here
I want to know how to solve this problem,or I don't know what's the problem?
Thank you very much!
I think DATABASES is right,
I want to connect mysql to django program named mysite, but I run 'python manage.py migrate':

django.db.utils.OperationalError: (2006, <NULL>)
Maybe it's because django can't support the new password encryption of mysql. You should try changing it.
You can do this from the mysql command line client:
I got the same OperationalError: (2006, <NULL>) when using python to connect to MySQL Server on Windows. It seems like the error has something to do with the new authentication method in MySQL 8. I reconfigured the MySQL server from using the recommended authentication method to "Use Legacy Authentication Method" and the error goes away.
I'm following this tutorial to configure my zappa app so I can use AWS lambda functions for my django app. I'm up to "Configure the database" so that's what I'm trying to do. My django app uses postgresql so I'm trying to change my zappa app to postgresql (from the default sqlite). I've successfully created a postgres DB instance on Amazon RDS. The instance setting Publicly accessible is set to Yes.
I've also successfully installed psycopg2 and psycopg2-binary in my zappa app, as well as changing my DB settings:
DATABASES = {
'default': {
'ENGINE': config('DB_ENGINE'),
'NAME': config('DB_NAME'),
'USER': config('DB_USER'),
'PASSWORD': config('DB_PASSWORD'),
'HOST': config('DB_HOST'),
'PORT': '5432',
}
}
However when I perform makemigrations in my zappa app I get the following error:

Is the server running on host "****-db.**********.us-east-2.rds.amazonaws.com" (14.171.84.91) and accepting
TCP/IP connections on port 5432?
Any idea what the problem is?
You need to open port 5432 on the aws firewall or on the box itself:
Here is a test on that port:
➜ nmap -Pn -p 5432 14.171.84.91

Host is up.

SOLVED: Issue was using USERNAME, not USER.
I am able to connect to the RDS instance from both MySQL Workbench and the mysql CLI command, so it is not the credentials that are the issue. I am trying to run python manage.py migrate but I get the following output:

raise exc
django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'xxx.xxx.us-west-2.rds.amazonaws.com' ([Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond)")
I've set the AWS Security Group and VPC Security Group with
All traffic | All | All | 0.0.0.0/0
I have the following in my settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'playercomp',
'USERNAME': 'xxx',
'PASSWORD': 'xxx',
'HOST': 'xxx.xxx.us-west-2.rds.amazonaws.com',
'PORT': '3306',
}
}
And this at the beginning of my manage.py
#!/usr/bin/env python
try:
import pymysql
pymysql.install_as_MySQLdb()
except ImportError:
print "Failed to import pymysql"
I'm just very confused since I can connect through mysql CLI, MySQL Workbench, and even through short python scripts like below.
connection = pymysql.connect(host='xxx.xx.us-west-2.rds.amazonaws.com',
user='xxx',
password='xxx',
db='playercomp',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
Solution was to change USERNAME to USER.
All the steps seem to be working fine but when I try to run heroku run python manage.py migrate it gives me an error saying Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?. I can't figure this part out. Do I need to change the settings of my postgresql database? But I have already existing data on my postgresql database.How will they get migrated into heroku if I change my database settings.
settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'music',
'USER': '**',
'PASSWORD': '**',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}

Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
The db server isn't running on the local machine on Heroku, of course. You should follow the documentation and use the dj-database-url library to set the db location automatically from the environment.
