The Zend OpCache<\/strong> provides faster PHP execution through opcode caching and optimization. It improves PHP performance by storing precompiled script bytecode in the shared memory.<\/p>\n

Installing Zend OPCache on PHP 5.3 or 5.4<\/strong><\/span><\/p>\n

1. Login to SSH on your server<\/p>\n

2. Type the following commands:<\/p>\n

#cd \/usr\/local\/src<\/em><\/p>\n

#wget http:\/\/pecl.php.net\/get\/ZendOpcache<\/em><\/p>\n

# to get the latest (master) build do the following instead:<\/p>\n

<\/p>\n

# wget https:\/\/github.com\/zendtech\/ZendOptimizerPlus\/archive\/master.zip<\/em><\/p>\n

#tar -xvfz ZendOpcache<\/em><\/p>\n

#cd zendopcache-7.x.x<\/em><\/p>\n

#phpize<\/em><\/p>\n

#whereis php-config<\/em><\/p>\n

# set the path below<\/p>\n

#.\/configure \u2013with-php-config=\/usr\/local\/bin\/php-config<\/em><\/p>\n

#make<\/em><\/p>\n

#make install<\/em><\/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: vi \/usr\/local\/lib\/php.ini<\/em><\/p>\n

5. Scroll down until you find the listing extension_dir = \u201c\/usr\/local\/lib\/php\/extensions\/no-debug-non-zts-XXXXXXXX\u201d<\/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<\/p>\n

opcache.enable=1<\/p>\n

opcache.enable_cli=1<\/p>\n

opcache.memory_consumption=128<\/p>\n

opcache.interned_strings_buffer=8<\/p>\n

opcache.max_accelerated_files=4000<\/p>\n

opcache.revalidate_freq=60<\/p>\n

opcache.fast_shutdown=1<\/p>\n

If xcache is installed, you should also comment all the xcache lines by putting a ; in front of them.<\/p>\n

7. Save and exit<\/p>\n

8. Type: service httpd restart<\/p>\n

9. Type: php -v<\/p>\n

10. This should show you that Zend OPcache is enabled.<\/p>\n
