Apache HTTP Server is an open-source web server platform. This article will outline the steps to install, configure, harden a zero-footprint instance of Apache 2.2 & 2.4, with particular focus on the nuances between each.
Prerequisites
If you are building you zero-footprint for the first time you will need a C/C++ compiler avaiable on the initial system. For the most part, most Unix/Linux distributions will come packaged with the gcc compiler.
Unix/Solaris
Check if gcc compiler is installed:
$ which gcc # which is dependent on environment variables being set correctly. # Alternatively check the /usr/bin and /usr/sfw/bin paths.
If no compiler found, install it:
$ pkg install gcc-3 # or whatever version you need
Linux
Chech if gcc compilete is installed:
$ which gcc
If no compiler found, install it:
# Debian/Ubuntu $ sudo apt-get install build-essential # RHEL/CentOS/Fedora $ sudo yum group install "Development Tools"
Initial Installation
The first step is to retrieve the source files from Apache. Grab the compressed files pertinent to the O/S you are using, typically bzip2 for Unix and gunzip for Linux:
