1. Login to SSH on your server<\/p>\n
2. Type the following commands:<\/p>\n
cd \/usr\/local\/src
\nwget http:\/\/pecl.php.net\/get\/ZendOpcache
\n# to get the latest (master) build do the following instead:
\n# wget https:\/\/github.com\/zendtech\/ZendOptimizerPlus\/archive\/master.zip
\ntar xvfz ZendOpcache
\ncd zendopcache-7.x.x
\nphpize
\nwhereis php-config
\n# set the path below
\n.\/configure –with-php-config=\/usr\/local\/bin\/php-config
\nmake
\nmake install<\/p>\n
3. Wait for the installation to complete. At the end it will tell you the location it has placed the file opcache.so. Ensure you have this location to your clipboard.<\/p>\n
4. Type: nano \/usr\/local\/lib\/php.ini<\/p>\n
5. Scroll down until you find the listing extension_dir = “\/usr\/local\/lib\/php\/extensions\/no-debug-non-zts-XXXXXXXX”<\/p>\n
6. Paste this in on a new line (make sure you replace the INSTALL LOCATION with the correct location from step 3):<\/p>\n
zend_extension=\/INSTALL LOCATION\/opcache.so
\nopcache.enable=1
\nopcache.enable_cli=1
\nopcache.memory_consumption=128
\nopcache.interned_strings_buffer=8
\nopcache.max_accelerated_files=4000
\nopcache.revalidate_freq=60
\nopcache.fast_shutdown=1
\nIf xcache is installed, you should also comment all the xcache lines by putting a ; in front of them.
\n5. Press Ctrl O to save the file<\/p>\n
6. Press Ctrl X to exit<\/p>\n
7. Type: service httpd restart<\/p>\n
8. Type: php -v<\/p>\n
9. This should show you that Zend OPcache is enabled.<\/p>\n

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.<\/p>\n
