Zend Optimizer (now part of Zend Guard) is a PHP extension that improves performance and enables execution of encrypted PHP files. If you need to install Zend on your cPanel server, cPanel provides a built-in script to simplify the process.
Step 1: Access Your Server via SSH
To install Zend, you need root access to your server. Connect using SSH:
ssh root@yourserver.com
Step 2: Run the Zend Installation Script
Once logged in, execute the following command:
/scripts/installzendopt
Step 3: Follow the On-Screen Instructions
The script will guide you through the installation process. Press Enter to accept default options and confirm the installation.
Step 4: Verify Zend Installation
After installation, confirm that Zend is enabled by running:
php -v
If Zend is successfully installed, you should see output similar to:
Zend Engine v3.4.0, Copyright (c) Zend Technologies
Restart Apache
To apply the changes, restart Apache:
service httpd restart
