Installing and supporting applications under Open Source technologies

DESCRIPTION
This course is intended for staff who are new to Open Source technologies and will be responsible for the installation, support and maintenance of Web applications using them.

The first part of the course gives you an overview of Linux / Unix / OSX operating systems (they're all similar) as a user, and also the administration functions. It then goes on to cover the aspects of networks and the web you'll need to know about if you're responsible for looking after web applications in Perl, PHP or Python on these platforms.

We have a brief look at the Perl and PHP languages, but this isn't a programming course - we concentrate on explaining, installing and configuring the languages and the various associated technologies. You'll learn how to troubleshoot problems even if you're not deep into the coding itself.

Web applications in Perl and PHP usually run via the Apache web server. Apache is a highly configurable pieces of software, and our course studies its sourcing, configuration and deployment and the deployment of application within it. Administration tasks such as monitoring logs, and setting up and watching security issues are also covered.

The final part of the course introduces relational databases, and taking MySQL as an example shows how it is added to the mix of technologies to provide a complete solution. Once again, we have a brief overview of the language (SQL) and we concentrate on installation, configuration, security, use in association with other technologies, data backup, and similar topics.
PREREQUISITES
You must be a competent computer user. Further experience is helpful, but this course is run for small groups and is tailored to fill in gaps in your knowledge.

SUBJECT BACKGROUND
More Internet domains are run using LAMP (Linux, Apache, MySQL, PHP) servers that any other technology. And if you have staff who are responsible for looking after these servers, or helping configure them, then this course provides an ideal knowledge level without turning them into knowledgeable programmers. It's ideal if they're going to be installing software written by others - for example using some of the wide range of Open Source applications which are available.
