How to install Zend Optimizer

If you’re in cPanel control panel, cPanel has an easy install process. You simply have to run:

/scripts/installzendopt

as root and fallow the install instructions. It’s as simple as clicking Next a few times.
After the install you can check to see if things are ok by running:

php -v

This should print something like:

If for some reason cPanel installs an old version, you have to edit /scripts/installzendopt (simply run “pico /scripts/installzendopt”) and edit “my %urls =” with the latest urls.

my %urls = (
