Python Web Scraping Cookbook

By: Michael Heydt

Overview of this book

Python Web Scraping Cookbook is a solution-focused book that will teach you techniques to develop high-performance scrapers and deal with crawlers, sitemaps, forms automation, Ajax-based sites, caches, and more. You'll explore a number of real-world scenarios where every part of the development/product life cycle will be fully covered. You will not only develop the skills needed to design and develop reliable performance data flows, but also deploy your codebase to AWS. If you are involved in software engineering, product development, or data mining (or are interested in building data-driven products), you will find this book useful as each recipe has a clear purpose and objective. Right from extracting data from the websites to writing a sophisticated web crawler, the book's independent recipes will be a godsend. This book covers Python libraries, requests, and BeautifulSoup. You will learn about crawling, web spidering, working with Ajax websites, paginated items, and more. You will also learn to tackle problems such as 403 errors, working with proxy, scraping images, and LXML. By the end of this book, you will be able to scrape websites more efficiently and able to deploy and operate your scraper in the cloud.

Installing a RabbitMQ container from Docker Hub

Pre-built containers can be obtained from a number of container repositories. Docker is preconfigured with connectivity to Docker Hub, where many software vendors, and also enthusiasts, publish containers with one or more configurations.

In this recipe, we will install RabbitMQ, which will be used by another tool we use in another recipe, Nameko, to function as the messaging bus for our scraping microservice.

Getting ready

Normally, the installation of RabbitMQ is a fairly simple process, but it does require several installers: one for Erlang, and then one for RabbitMQ itself. If management tools, such as the web-based administrative GUI are desired, that is yet one more step...
