How to Install Zend Optimizer on RedHat Enterprise Linux (RHEL)
If you are setting up a web server then having Zend's "Optimizer" for your server is a necessary evil for just about any client who uses PHP.
Sometimes it can be tricky to install, I will guide you through the process.
- Difficulty:
- Moderately Easy
Instructions

1
SSH and connect to your box as your wheel group user, and then "su -" to root.
-
2
Download the file you need from Zend directly. This page requires you to setup a free account with them to access the download page.

3
Once you have the file, copy it to your ~ directory on the linux server.
-
4
If you have a GZ file:
gzip -d ~/ZendOptimizer-3.3.0-linux-glibc21-i386.tar.gzNow that you have a tar (or started with a tar)
tar -xvf ~/ZendOptimizer-3.3.0-linux-glibc21-i386.tar -
5
Change directory and then run the installer script.
cd ~/ZendOptimizer-3.3.0-linux-glibc21-i386
./install.sh -
6
make sure that the end of your php.ini file looks like this - if not change it (this is assuming your installing version 3.3.0)
[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=3.3.0
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so -
7
Save and close the file if you change it. Then restart Apache to pick up the changes.
/sbin/service httpd restart
-
8
Now verify from the php CLI that its installed and working.
php -v
You should see something similar to
