mod_wsgi is an Apache HTTP Server module that provides a WSGI-compliant interface for hosting Python web applications. It is commonly used to deploy Python-based web applications with Apache. In this guide, we will walk you through how to run Python scripts using Apache and mod_wsgi on Ubuntu 18.04 LTS. Whether you’re using a or another hosting provider, this setup will allow you to efficiently deploy Python applications on your server.<\/p>\n
Before starting, ensure you have the following:<\/p>\n
First, update your system\u2019s package index and install Apache with mod_wsgi:<\/p>\n
sudo apt update\r\nsudo apt install apache2 libapache2-mod-wsgi-py3 -y<\/code><\/pre>\nAfter installation, start and enable Apache:<\/p>\n
sudo systemctl start apache2\r\nsudo systemctl enable apache2<\/code><\/pre>\nStep 2: Install Python 3<\/h2>\n
Ubuntu 18.04 comes with Python 3 pre-installed. To ensure Python 3 is available, verify the installation with the following command:<\/p>\n
python3 --version<\/code><\/pre>\nIf Python 3 is not installed, you can install it using:<\/p>\n
sudo apt install python3 -y<\/code><\/pre>\nStep 3: Create a Python Application<\/h2>\n
In this step, you will create a basic Python WSGI application to test mod_wsgi. First, create a directory to hold your Python app:<\/p>\n
sudo mkdir \/var\/www\/html\/myapp<\/code><\/pre>\nNavigate to the newly created directory and create a Python WSGI application file:<\/p>\n
cd \/var\/www\/html\/myapp\r\nsudo nano myapp.wsgi<\/code><\/pre>\nAdd the following content to the myapp.wsgi<\/code> file:<\/p>\ndef application(environ, start_response):\r\n status = '200 OK'\r\n output = b'Hello from WSGI!'\r\n\r\n response_headers = [('Content-type', 'text\/plain'), ('Content-Length', str(len(output)))]\r\n start_response(status, response_headers)\r\n\r\n return [output]<\/code><\/pre>\nThis is a basic WSGI application that returns a “Hello from WSGI!” message when accessed via a web browser.<\/p>\n
Step 4: Configure Apache to Serve Python Application<\/h2>\n
Now you need to configure Apache to serve your Python WSGI application. Create a new virtual host configuration file for your app:<\/p>\n
sudo nano \/etc\/apache2\/sites-available\/myapp.conf<\/code><\/pre>\nAdd the following configuration:<\/p>\n
<VirtualHost *:80>\r\n ServerName your-domain.com\r\n DocumentRoot \/var\/www\/html\/myapp\r\n\r\n WSGIDaemonProcess myapp python-path=\/var\/www\/html\/myapp\r\n WSGIProcessGroup myapp\r\n WSGIScriptAlias \/ \/var\/www\/html\/myapp\/myapp.wsgi\r\n\r\n <Directory \/var\/www\/html\/myapp>\r\n Require all granted\r\n <\/Directory>\r\n<\/VirtualHost><\/code><\/pre>\nReplace your-domain.com<\/code> with your actual domain. Save the file and exit.<\/p>\nEnable the new virtual host and disable the default one:<\/p>\n
sudo a2ensite myapp.conf\r\nsudo a2dissite 000-default.conf\r\nsudo systemctl reload apache2<\/code><\/pre>\nStep 5: Test the Python Application<\/h2>\n
To test if everything is working, open your web browser and navigate to http:\/\/your-domain.com<\/code>. You should see the message “Hello from WSGI!” displayed in the browser.<\/p>\nStep 6: Secure Your Application with Let’s Encrypt SSL (Optional)<\/h2>\n
If you want to secure your Python web application with SSL, you can use Let’s Encrypt. Install Certbot by running:<\/p>\n
sudo apt install certbot python3-certbot-apache -y<\/code><\/pre>\nObtain an SSL certificate for your domain:<\/p>\n
sudo certbot --apache -d your-domain.com -d www.your-domain.com<\/code><\/pre>\nFollow the prompts to install and configure SSL for your Apache server. Certbot will automatically configure Apache to redirect HTTP traffic to HTTPS.<\/p>\n
Conclusion<\/h2>\n
By following these steps, you have successfully set up Apache with mod_wsgi to run Python scripts on Ubuntu 18.04 LTS. This allows you to deploy Python web applications efficiently, whether you are using a , Microsoft SQL VPS Windows<\/a>, or another Windows VPSVirtual Private Server Hosting<\/a> solution. With mod_wsgi and Apache, you can ensure high performance and scalability for your Python applications.<\/p>\n
