远程连接到 Django postgres 数据库

Question

I am using Postgres for a production system, and I would like to be able to connect to this database remotely to integrate the information with other systems.

My configuration looks classic like follows :

ALLOWED_HOSTS = ['myipgoeshere', 'mydomainnamegoeshere']

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'dbname',
        'USER': 'dbuser',
        'PASSWORD': 'dbpassword',
        'HOST': 'localhost'
    }
}

Now, if I want to connect to this database from another machine what should I use as hostname on that machine ?

I need to provide information about

Host
Database
Port
User
Password

In my config, host is localhost, but I cannot use this as remote hostname, should we use the IP address instead ? Also will the port be the default postgres one?

Answer 1

You can make the "HOST" like the usual host in a URL, for example a domain name or IP address.

To specify the port, you can add a field called "PORT" to your database config. The default port for Postgres is 5432 , but can be any valid port.

For example:

DATABASES = {
    'default': {
        # ...
        'HOST': 'mydatabasehost.com', # e.g. or 192.168.0.10
        'PORT': '5432',
    }
}

我通过在默认情况下具有 localhost 的 postgress 配置文件中添加 IP 来解决问题，并在我开始在 django 配置中使用 IP 之后
