How to deploying multiple Django blog sites on a single server

To deploy multiple Django blog sites on a single server using Gunicorn, you will need to follow these general steps:

1. Set up your server with a Linux operating system and install necessary dependencies such as Python, Django, and Gunicorn.

2. Create a new virtual environment for each Django blog site, and install the necessary packages for each site.

3. Configure Gunicorn to run each Django site using a separate socket and process. This can typically be done by creating a separate Gunicorn service file for each site and specifying the correct socket and process settings.

4. Configure your server's web server (such as Nginx) to proxy requests to the correct Gunicorn process based on the domain or subdomain being accessed.

5. Start Gunicorn and the web server, and ensure that they are set to start automatically on system boot.

6. Test that each site is accessible by visiting the appropriate domain or subdomain in a web browser.

It's worth noting that this is a general overview of the process and the exact steps may differ depending on the specific details of your environment.

A full configuration for deploying multiple Django blog sites with Gunicorn on a single server would include the following steps:

1. Install necessary dependencies:

• Linux operating system (e.g. Ubuntu)
• Python
• Django
• Gunicorn
• Nginx (or another web server)

2. Create a new virtual environment for each Django blog site:

python -m venv mysite1
source mysite1/bin/activate
pip install django
deactivate

python -m venv mysite2
source mysite2/bin/activate
pip install django
deactivate

3. Configure Gunicorn to run each Django site using a separate socket and process:

sudo nano /etc/systemd/system/mysite1.service

[Unit]
Description=Gunicorn instance to serve mysite1
After=network.target

[Service]
User=username
Group=www-data
WorkingDirectory=/home/username/mysite1
Environment="PATH=/home/username/mysite1/bin"
ExecStart=/home/username/mysite1/bin/gunicorn --workers 3 --bind unix:/run/gunicorn.sock mysite1.wsgi:application

[Install]
WantedBy=multi-user.target

sudo nano /etc/systemd/system/mysite2.service

[Unit]
Description=Gunicorn instance to serve mysite2
After=network.target

[Service]
User=username
Group=www-data
WorkingDirectory=/home/username/mysite2
Environment="PATH=/home/username/mysite2/bin"
ExecStart=/home/username/mysite2/bin/gunicorn --workers 3 --bind unix:/run/gunicorn.sock mysite2.wsgi:application

[Install]
WantedBy=multi-user.target

4. Configure Nginx to proxy requests to the correct Gunicorn process based on the domain or subdomain being accessed:

sudo nano /etc/nginx/sites-available/mysite1

server {
    listen 80;
    server_name mysite1.com;

    location = /favicon.ico { access_log off; log_not_found off; }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

sudo nano /etc/nginx/sites-available/mysite2

server {
    listen 80;
    server_name mysite2.com;

    location = /favicon.ico { access_log off; log_not_found off; }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

5. Start Gunicorn and Nginx and ensure that they are set to start automatically on system boot:

sudo systemctl start mysite1
sudo systemctl enable mysite1
sudo systemctl start mysite2
sudo systemctl enable mysite2
sudo systemctl start nginx
sudo systemctl
