Installing sSMTP MTA (Mail Transfer Agent)
sSMTP is an extremely simple MTA to get mail off the system to a mail hub. It contains no suid-binaries or other dangerous things - no mail spool to poke around in, and no daemons running in the background. Mail is simply forwarded to the configured mailhost. Extremely easy configuration.
This is ideal for web servers to avoid running MTA daemons like sendmail, Exim and Postfix which use up resources on the server.
1. Install sSMTP (Note: Any previously installed MTA will be removed)
apt-get install ssmtp
How to install LAMP (Apache, PHP and MySql in Linux)

1. Install Apache2 and PHP5 (as an Apache module)
apt-get install apache2 php5 libapache2-mod-php5 php5-mysql
Installing eAccelerator
eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.
eAccelerator only works with mod_php or php in fastcgi mode. It can't be used in cgi or cli because eAccelerator needs to set up shared memory, and this can only be done when all php instances that need to access it are forks of the first process.
1. Download the eAccelerator source. The latest version is mirrored on www.debiantutorials.com as it's not available on the official site anymore.
cd /tmp
wget http://www.debiantutorials.com/static/eaccelerator-0.9.6.1.tar.bz2
Running Apache2 virtual hosts as different users with mpm-itk

1. Install the apache2-mpm-itk package
apt-get install apache2-mpm-itk
