Install Zend Optimizer on Plesk Server.

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
