Now that you have your development environment set up, let’s get your production application server set up with Gunicorn on web-01, port 5000. You’ll need to install Gunicorn and any libraries required by your application. Your Flask application object will serve as a WSGI entry point into your application. This will be your production environment. As you can see we want the production and development of your application to use the same port, so the conditions for serving your dynamic content are the same in both environments.Requirements:Install Gunicorn and any other libraries required by your application.The Flask application object should be called app. (This will allow us to run and check your code)You will serve the same content from the same route as in the previous task. You can verify that it’s working by binding a Gunicorn instance to localhost listening on port 5000 with your application object as the entry point.In order to check your code, the checker will bind a Gunicorn instance to port 6000, so make sure nothing is listening on that port.Example:Terminal 1:ubuntu@229-web-01:~/AirBnB_clone_v2$ gunicorn --bind 0.0.0.0:5000 web_flask.0-hello_route:app[2019-05-03 20:47:20 +0000] [3595] [INFO] Starting gunicorn 19.9.0[2019-05-03 20:47:20 +0000] [3595] [INFO] Listening at: http://0.0.0.0:5000 (3595)[2019-05-03 20:47:20 +0000] [3595] [INFO] Using worker: sync[2019-05-03 20:47:20 +0000] [3598] [INFO] Booting worker with pid: 3598Terminal 2:ubuntu@229-web-01:~$ curl 127.0.0.1:5000/airbnb-onepage/Hello HBNB!ubuntu@229-web-01:~$

Here are the steps to set up your production application server with Gunicorn on web-01, port 5000:

1. Install Gunicorn: Gunicorn is a Python WSGI HTTP Server for UNIX. You can install it using pip, which is a package manager for Python. Use the following command to install Gunicorn:

   pip install gunicorn
   

2. Install any other libraries required by your application: If your application requires other libraries, you can install them using pip. For example, if your application requires Flask, you can install it using the following command:

   pip install flask
   

3. Create your Flask application object: Your Flask application object will serve as a WSGI entry point into your application. You should name this object "app". Here is an example of how to create a Flask application object:

   from flask import Flask
   app = Flask(__name__)
   

4. Serve the same content from the same route as in the previous task: You can use the route decorator in Flask to specify the URL that should trigger our function. Here is an example:

   @app.route('/')
   def hello_world():
       return 'Hello, World!'
   

5. Bind a Gunicorn instance to localhost listening on port 5000 with your application object as the entry point: You can do this using the following command:

   gunicorn --bind 0.0.0.0:5000 your_application:app
   

   Replace "your_application" with the name of your Python file that contains the Flask application object.

6. Make sure nothing is listening on port 6000: The checker will bind a Gunicorn instance to port 6000 to check your code. You can use the following command to check if anything is listening on port 6000:

   netstat -an | grep 6000
   

   If anything is listening on port 6000, you will need to stop it.

7. Test your setup: You can test your setup by accessing your application in a web browser or using curl. Here is an example of how to use curl:

   curl 127.0.0.1:5000/
   

   This should return the same content as in the previous task.
