Before you start
Learn what these tutorials can teach you and how you can get the most from them.
The Linux Professional Institute (LPI) certifies Linux system administrators at two levels: junior level (also called "certification level 1") and intermediate level (also called "certification level 2"). To attain certification level 1, you must pass exams 101 and 102; to attain certification level 2, you must pass exams 201 and 202.
developerWorks offers tutorials to help you prepare for each of the four exams. Each exam covers several topics, and each topic has a corresponding self-study tutorial on developerWorks. For LPI exam 202, the seven topics and corresponding developerWorks tutorials are:

Welcome to "Web services," the fourth of seven tutorials covering intermediate network administration on Linux. In this tutorial, you learn how to configure and run the Apache HTTP server and the Squid Web Proxy Cache.
As with the other tutorials in the developerWorks 201 and 202 series, this tutorial is intended to serve as a study guide and entry point for exam preparation, rather than complete documentation on the subject. Readers are encouraged to consult LPI's detailed objectives list and to supplement the information provided here with other material as needed.
This tutorial is organized according to the LPI objectives for this topic. Very roughly, expect more questions on the exam for objectives with higher weight.
|LPI exam objective||Objective weight||Objective summary|
Implementing a Web server
|Weight 2||Install and configure a Web server. This objective includes monitoring the server's load and performance, restricting client user access, configuring support for scripting languages as modules, and setting up client user authentication. Also included is the ability to configure server options to restrict usage of resources.|
Maintaining a Web server
|Weight 2||Configure a Web server to use virtual hosts, Secure Sockets Layer (SSL), and customize file access.|
