Python Apache Web Server

 



Web servers respond toHypertext Transfer Protocol (HTTP)requests from clients and send back a response containing a status code andoften content such as HTML, XML or JSON as well.

Why are web servers necessary?

Web servers are the ying to the web client's yang. The server and client speakthe standardized language of the World Wide Web. This standard languageis why an old Mozilla Netscape browser can still talk to a modern Apache orNginx web server, even if it cannot properly render the page design like amodern web browser can.

The final step is to tie the knot between your python website and Apache web server. This is done by executing the below command in terminal. This adds a virtual path to Apache and the Python application would be served as a WSGI application by Apache web server. Sudo /usr/sbin/a2ensite sysinfo.conf. Check Apache Page. If you wish, you can now stop the container. $ sudo docker stop tecmint-web and remove it: $ sudo docker rm tecmint-web To finish cleaning up, you may want to delete the image that was used in the container (omit this step if you’re planning on creating other Apache 2.4 containers soon). Step 4 — Installing Apache 2. In this section, we will install Apache 2, and ensure that it recognizes Python files as executables. Install Apache using apt-get: sudo apt-get install apache2 Like MySQL, the Apache server will start once the installation completes. Note: After installation, several ports are open to the internet. Matching: Your web server now uses a program to match the user’s request to a particular portion of your Python script. Running: The appropriate Python code is called up by that program. When your code runs, it writes out a web page as a response. Delivering: The program then delivers this response back to your user through the web server.

Python

The basic language of the Web with the request and response cycle fromclient to server then server back to client remains the same as it was whenthe Web was invented byTim Berners-Lee at CERN in 1989.Modern browsers and web servers have simply extended the language of the Webto incorporate new standards.

There are already python-based web servers, such as CherryPy (which I think is intended to be a web server solution on the same stack level as Apache; it is more python-based though, and Apache has been around a lot longer).

Web server implementations

The conceptual web server idea can be implemented in various ways. Thefollowing web server implementations each have varying features, extensionsand configurations.

  • The Apache HTTP Server has been the mostcommonly deployed web server on the Internet for 20+ years.

  • Nginx is the second most commonly used server for thetop 100,000 websites and often serves as a reverse proxy forPython WSGI servers.

  • Caddy is a newcomer to the web server sceneand is focused on serving the HTTP/2 protocol with HTTPS.

  • rwasa is a newer web server writtenin Assembly with no external dependencies that tuned to be faster than Nginx.The benchmarks are worth taking a look at to see if this server could fityour needs if you need the fastest performance trading off for as of yetuntested web server.

Client requests

A client that sends a request to a web server is usually a browser suchas Internet Explorer, Firefox, or Chrome, but it can also be a

  • headless browser, commonly use for testing, such asphantomjs
  • commandline utility, for example wgetand cURL
  • text-based web browser such asLynx
  • web crawler.

Web servers process requests from the above clients. The result of the webserver's processing is aresponse codeand commonly a content response. Some status codes, such as 204 (No content)and 403 (Forbidden), do not have content responses.

In a simple case, the client will request a static asset such as a pictureor JavaScript file. The file sits on the file system in a location theweb server is authorized to access and the web server sends the fileto the client with a 200 status code. If the client already requested thefile and the file has not changed, the web server will pass back a 304'Not modified' response indicating the client already has the latest versionof that file.

A web server sends files to a web browser based on the web browser'srequest. In the first request, the browser accessed the'www.fullstackpython.com'address and the server responded with the index.html HTML-formatted file.That HTML file contained references to other files, such as style.css andscript.js that the browser then requested from the server.

Sending static assets (such as CSS and JavaScript files) can eat up alarge amount of bandwidth which is why using a Content Delivery Network(CDN) to serve static assets is important whenpossible.

Web servers learning checklist

  1. Choose a web server. Nginx is often recommendedalthough Apache is also a great choice.

  2. Create an SSL certificate via Let's Encrypt.You will need SSL for serving HTTPS traffic and preventing myriadsecurity issues that occur with unencrypted user input.

  3. Configure the web server to serve up static files such asCSS, JavaScriptand images.

  4. Once you set up the WSGI server you'll need toconfigure the web server as a pass through for dynamic content.

The Apache HTTP Server is a widely deployed web serverthat can be used in combination with a WSGI module, such as mod_wsgi or astand-alone WSGI server to run Python web applications.

Why is the Apache HTTP Server important?

Apache remains the most commonly deployed web server with a reign of20+ years. Its wide usage contributes to the large number of tutorialsand open source modules created by developers for anyone to use.

Apache's development began in mid-1994 as a fork of theNCSA HTTP Server project.By early 1996, Apache overtook the previously dominant but suddenly stagnantNCSA server as NCSA's progress stalled due to signficantly reduceddevelopment attention.

The Apache HTTP Server is an implementation of the web server concept. Learn how these pieces fit together in the deployment chapter or view the table of contents for all topics.
