How To Install Zend OPCache on cPanel Servers

Written by: on 04 June 2016 05:49 PM 04 June 2016 05:49 PM

To get the best performance out of cPanel servers it is advisable to install Zend OPcache.

Installing Zend OPCache on cPanel Servers

1. Login to SSH on your server

2. Type the following commands:

cd /usr/local/src
# to get the latest (master) build do the following instead:
# wget
tar xvfz ZendOpcache
cd zendopcache-7.x.x
whereis php-config 
# set the path below
./configure --with-php-config=/usr/local/bin/php-config
make install

3. Wait for the installation to complete. At the end it will tell you the location it has placed the file Ensure you have this location to your clipboard.

4. Type: nano /usr/local/lib/php.ini

5. Scroll down until you find the listing extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-XXXXXXXX"

6. Paste this in on a new line (make sure you replace the INSTALL LOCATION with the correct location from step 3). Also note if there is already a zend_extension line loading ioncube loader, make sure you paste this BELOW that line:

zend_extension=/INSTALL LOCATION/
If xcache is installed, you should also comment all the xcache lines by putting a ; in front of them.

5. Press Ctrl O to save the file

6. Press Ctrl X to exit

7. Type: service httpd restart

8. Type: php -v

9. This should show you that Zend OPcache is enabled.

If it does not and gives an error about wrong version of the Zend API then you specified the incorrect PHP location in step 2. Go back to step 2 and when you type phpize, use the alternative location for php in your configure script.
