HowTo: Run Network Service Per System / VM Instance To Improve Overall Security Of A Web Stacks (LAMP)

last updated in Categories Apache, Linux

A web stack is nothing but collection of many open source software such as an operating system, Web server, database server, server side programming language. The most commonly known web stacks is LAMP. It is an acronym for a solution stack of free, open source software, referring to the first letters of Linux (operating system), Apache Web server, MySQL database software and PHP (or sometimes Perl or Python). All of our security related tutorials recommends running different network services on separate systems or vm instance. Naturally, this limits the number of other services that can be cracked in the event that an attacker is able to successfully exploit a software flaw in one network service. This is also one of the most requested article via email. In this guide, I will explain how to setup a solution that can serve static content, dynamic content, database, and caching by running on separate servers or vm instance.

HowTo: Use Nginx As Reverse Proxy Server

last updated in Categories Linux

Nginx is an open source Web server and a reverse proxy server. You can use nginx for a load balancing and/or as a proxy solution to run services from inside those machines through your host’s single public IP address such as 202.54.1.1. In this post, I will explain how to install nginx as reverse proxy server for Apache+php5 domain called www.example.com and Lighttpd static asset domain called static.example.com. You need to type the following commands on vm00 having an IP address 192.168.1.1 only.
