Installing Zend Optimizer on Ubuntu-Plesk VPS

[WHUK Alec]

For installing and integrating the Zend Optimizer with php on a Linux - ubunto vps with plesk panel, you can follow the given steps :

1) You can download the latest compatible version of Zend Optimizer archive in tar.gz format from the site http://www.zend.com/products/guard/downloads
depending on the architecture of the server. (to get the architecture of your Linux vps, you can use command : uname -m)

cd /usr/local/src

wget http://downloads.zend.com/optimizer/...23-i386.tar.gz

2) Unzip (untar) the archive to extract files/folders in it.

tar -zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz

3) Copy the extracted Zend Optimizer ".so" file to /usr/local/ folder
(Select the compatible .so file depending on the version of php on your vps. For eg : php 4.X.X, php 5.X.X etc.)

cd ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp

cp ZendOptimizer.so /usr/local/

4) Edit the php.ini file and specify the full path of Zend Optimizer ".so" file to zend_extension.
(to get the absolute path of php.ini file on server, you can use command : php -i | grep php.ini)

php -i | grep php.ini

vi /etc/php5/cli/php.ini

Search for string "zend_extension" and add the line as follows in php.ini file :

zend_extension=/usr/local/ZendOptimizer.so

(you need to add the above line under "zend.ze1_compatibility_mode = Off" line and followed by IonCube Loader extension entry.)

; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
zend.ze1_compatibility_mode = Off
zend_extension=/usr/local/ioncube_loader_lin_5.2.so
zend_extension=/usr/local/ZendOptimizer.so

5) restart apche service

/etc/init.d/apache2 restart

6) confim the Zend Optimizer php module by command :

php -v

You should get the output similar to following :
