How To Install Flask Nginx On Ubuntu 1604
Introduction
Flask is a web application framework based on Python. It is highly useful for web developers due to its flexibility and scalability. This tutorial will focus on deploying Flask applications on an Ubuntu 16.04 server with Nginx as the web server and uWSGI as WSGI server. It will also offer instructions on setting up a virtual environment. At the end, you will have a working Flask application on your Ubuntu 16.04 server.
Setting Up Prerequisites
The first thing to do is to make sure that all packages are up to date. This can be done by running the following commands in the terminal:
sudo apt-get update
sudo apt-get upgrade
Once the packages are up to date, we’ll need to install the components necessary for our Flask application. This includes Nginx, uWSGI and Python. We can install these packages by running the following command:
sudo apt-get install nginx uwsgi python-dev
Create a Virtual Environment
Once the packages have been installed, it’s time to create a virtual environment. This allows us to isolate our application from the rest of the system. This is done by running the following commands in the terminal:
sudo mkdir ~/myproject
cd ~/myproject
sudo virtualenv env
Once the virtual environment is created, it needs to be activated:
source env/bin/activate
Once the virtual environment is activated, all packages will be installed inside it. This is important, as all packages that are installed when the virtual environment is active will be available to the project.
Install Flask and Install uWSGI
Now that our virtual environment is ready, we can install Flask and uWSGI. To do this, use the following commands:
pip install Flask
pip install uwsgi
Once the packages have been installed, it’s time to configure our Flask application. This is done in the Flask application file, usually named app.py. The following is an example of a simple application:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello, World!"
if __name__ == "__main__":
app.run()
Once this file is ready, it needs to be configured with uWSGI. To do this, create a configuration file in the project directory, called mysite.ini:
[uwsgi]
module = app
master = true
processes = 5
socket = mysite.sock
chmod-socket = 660
vacuum = true
die-on-term = true
Configure Nginx
Once the application is ready, it’s time to configure Nginx. This can be done by creating a configuration file in the /etc/nginx/conf.d/ directory. The file should be called “mysite”. The following is an example configuration file:
server {
listen 80;
server_name your_domain.com;
location / {
include uwsgi_params;
uwsgi_pass unix:/home/user/myproject/mysite.sock;
}
}
Once the configuration file is in place, the application needs to be enabled. To do this, run the following command:
sudo ln -s /etc/nginx/sites-available/mysite /etc/nginx/sites-enabled
Once the application is enabled, Nginx needs to be restarted. This can be done by running the following command:
sudo service nginx restart
Test the Application
Now that the application is up and running, it’s time to test it. To do this, open a web browser and navigate to http://your_domain.com. You should see the message “Hello, World!” if everything is working as expected.
Conclusion
This tutorial has shown you how to deploy Flask applications on an Ubuntu 16.04 server using Nginx and uWSGI. We have also gone through the steps of setting up a virtual environment and configuring Nginx. With the help of this tutorial, you should now have a working Flask application on your server.
