Installing Zend Optimizer

This tutorial is for older Debian versions and may not work for current versions

The Zend Optimizer enables you to run Zend Guard encoded files.

1. Download a copy of Zend Optimizer / Guard from the location below and put it into /tmp


2. Extract

cd /tmp
tar zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz

Replace with your actual filename

3. Create a directory to contain Zend optimizer

mkdir /usr/local/lib/Zend

3. Move the Zend optimizer lib to a permanent location

mv ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ /usr/local/lib/Zend/

Your ZendOptimizer directory name may be different since it includes version numbers and platform. I’m using the 5_2_x_comp directory because I have PHP 5.2 installed.

4. Add reference to your php.ini file (pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/lib/Zend/
zend_optimizer.optimization_level = 15

5. Restart apache

/etc/init.d/apache2 restart
