Installing Zend Optimizer

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

http://www.zend.com/en/products/guard/downloads


2. Extract

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


Replace with your actual filename

3. Create a directory to contain Zend optimizer

sudo mkdir /usr/local/lib/Zend


3. Move the Zend optimizer lib to a permanent location

sudo mv ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /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 (sudo pico /etc/php5/apache2/php.ini)

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


5. Restart apache

sudo /etc/init.d/apache2 restart
