You have a typo in your databases settings.
'USRE': 'postgres',
should be
'USER': 'postgres',

django connec mysql --_mysql_exceptions.OperationalError: (2006, <NULL>)

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'),
# }

'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.

Deploy Django on AWS Elastic Beanstalk cannot connect to sql server

I'm trying to deploy django on to AWS EB. I have a RDS linked to the instance and database is migrated without any problem.
When I log onto the server using ssh and try to create a superuser, I run into following errors:
django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on '127.0.0.1' (111)")
I used the same setup for several other django site, didn't have the same problem.
The only difference this time is in the view I'm using native sql, I wonder if the connection.cursor() is causing this problem.
In settings I have:
if 'RDS_HOSTNAME' in os.environ:
print "live site server connection: ", os.environ['RDS_HOSTNAME']
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': os.environ['RDS_DB_NAME'],
'OPTIONS': {
'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
},
'USER': os.environ['RDS_USERNAME'],
'PASSWORD': os.environ['RDS_PASSWORD'],
'HOST': os.environ['RDS_HOSTNAME'],
'PORT': os.environ['RDS_PORT'],
}
}
else:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'new_dash',
'USER': 'root',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}

Unable to apply django migrations to postgres database

My django project earlier used sqlite, but now we have changed it to use Postgresql. Here are the new settings:
DATABASES = {

'USER': 'root',
'PASSWORD': '',
'HOST': 'localhost',

}
}
I have created a db vader and user root as its owner. Now, when I try to apply migrations with:
python manage.py migrate
I get the following error:

django.db.utils.OperationalError: fe_sendauth: no password supplied
It is saying no password supplied, but I am not sure where to pass the password. Any ideas what I can do to fix this?

You need to add your database user password to your settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'vader',
'USER': 'root',
# Add password here
'PASSWORD': '',
'HOST': 'localhost',
'PORT': '5432',
}
}

You need to remove PASSWORD, HOST and PORT like this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'vader',
'USER': 'root'
}
}
Then do the migrate again.

django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
my settings.py is
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'elfmsdb',
'USER': 'postgres',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
i also checked the postgresql.conf and it is using 5432 as port.
another odd thing is that i accidentally runserver outside my virtualenv and it worked but the django version is 1.6.
please help me, thanks a lot!

I dont know what the problem is but i tried
$sudo service postgresql restart
and runserver worked after that.

may be you can try with this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'elfmsdb',
'USER': 'postgres',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
