Setting Up Multiple Django Projects with Subdomains

Based on the information available, I can provide guidance on setting up multiple Django projects using subdomains. This approach involves using Django's multiple admin sites feature, but extends to running completely separate Django projects.

Step 1: DNS Configuration

First, you need to configure your domain's DNS settings to point subdomains to your VPS:

1. Log into your domain registrar's control panel
2. Create A records for each subdomain (e.g., project1.yourdomain.com, project2.yourdomain.com) pointing to your VPS IP address

Step 2: Web Server Configuration

You'll need to set up a web server (like Nginx) to route requests to the appropriate Django application:

NGINXCopied
# Example Nginx configuration for multiple Django projects

# First Django project
server {
    listen 80;
    server_name project1.yourdomain.com;

    location / {
        proxy_pass http://127.0.0.1:8001;  # Port where first Django project runs
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

# Second Django project
server {
    listen 80;
    server_name project2.yourdomain.com;

    location / {
        proxy_pass http://127.0.0.1:8002;  # Port where second Django project runs
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Step 3: Django Project Configuration

For each Django project, you'll need to:

1. Configure the ALLOWED_HOSTS setting in each project's settings.py:

PYTHONCopied
# For project1
ALLOWED_HOSTS = ['project1.yourdomain.com']

# For project2
ALLOWED_HOSTS = ['project2.yourdomain.com']

2. Run each Django project on a different port:

# For project1
python manage.py runserver 127.0.0.1:8001

# For project2
python manage.py runserver 127.0.0.1:8002

Step 4: Production Deployment

For production, you should use a WSGI/ASGI server like Gunicorn or Daphne instead of Django's development server:

BASHCopied
# Example using Gunicorn
# For project1
gunicorn --bind 127.0.0.1:8001 project1.wsgi:application

# For project2
gunicorn --bind 127.0.0.1:8002 project2.wsgi:application

You can use a process manager like Supervisor or systemd to ensure these services stay running.

Alternative: Using Multiple Admin Sites

If you're looking to run multiple admin interfaces within a single Django project (rather than completely separate projects), you can use Django's multiple admin sites feature:

PYTHONCopied
# admin.py
from django.contrib.admin import AdminSite

class Project1AdminSite(AdminSite):
    site_header = "Project 1 Admin"
    site_title = "Project 1 Admin Portal"
    index_title = "Welcome to Project 1 Admin"

class Project2AdminSite(AdminSite):
    site_header = "Project 2 Admin"
    site_title = "Project 2 Admin Portal"
    index_title = "Welcome to Project 2 Admin"

project1_admin = Project1AdminSite(name='project1_admin')
project2_admin = Project2AdminSite(name='project2_admin')

# Register your models with each admin site
project1_admin.register(YourModel1)
project2_admin.register(YourModel2)

Then in your urls.py:

PYTHONCopied
from django.urls import path
from myproject.admin import project1_admin, project2_admin

urlpatterns = [
    path("project1-admin/", project1_admin.urls),
    path("project2-admin/", project2_admin.urls),
]

This approach is simpler but only separates the admin interfaces, not the entire projects.
