How to install Zend Optimizer on Plesk or on any plain server?

[Rock]

Hi,

As cPanel provides a built-in or rather ready made script (/scripts/installzendopt) for installing Zend Optimizer, I have come across many people asking questions about installing Zend Optimizer on Plesk Control Panel or on any other plain server (non-control-panel server).

Here are the most simple steps to install ZendOptimizer-3.0.1 on Plesk:

cd /usr/local/src
wget http://www.eth0.us/files/ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
tar -zxf ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
cd ZendOptimizer-3.0.1-linux-glibc21-i386
./install

Now just hit enter a few times until it is done...

That's it !!!

Another good tutorial - thank you! The tutorials seem to becoming more faster these days - which is always a good sign .

Im suspicious.... this looks just a little too easy!

Im sure i can manage to screw this up one way or another!

Just one question, before i give this a go. Will this direct to the latest version of Zend, or do i need to adjust the code to do this?

Thanks

Andy.

You'd need to change the code to match the latest version of Zend Optimizer available here

PROBLEM
Getting following error after installation of Zend Optimizer on a Plesk server,

[root@vps ~]# php -v
PHP Fatal error: [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0
[root@vps ~]#

CAUSE
This error occurs because of incorrect extensions order in PHP configuration.

RESOLUTION
Zend extensions can be loaded directly from /etc/php.ini file or included from /etc/php.d/ directory. In both ways they should be loaded in the right order.

If extensions are loaded from "/etc/php.ini"

then 'ioncube' line like zend_extension=/usr/lib/ioncube/php_ioncube_loader_lin_X.X.so
in /etc/php.ini must appear before Zend configuration sections, that usually begins with [Zend]

If extensions are loaded from /etc/php.d,they are loaded in alphabetical order of files. Usually 'ioncube' file is named /etc/php.d/ioncube.ini and zend is /etc/php.d/zend.ini.

zend.ini section looks like this,
[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.0
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.0
zend_optimizer.version=3.3.0a
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

then restart apache service

/sbin/service httpd restart

verified output

[root@vps ~]# php -v
PHP 5.1.6 (cli) (built: May 9 2007 11:29:06)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
with the ionCube PHP Loader v3.1.28, Copyright (c) 2002-2007, by ionCube Ltd., and
with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies
with Zend Optimizer v3.3.0, Copyright (c) 1998-2007, by Zend Technologies
[root@vps ~]#

Now everything works, and Zend is properly displayed in php.ini
