Description : PHP is an HTML-embedded scripting language. PHP attempts to make
            : it easy for developers to write dynamically generated web pages.
            : PHP also offers built-in database integration for several
            : commercial and non-commercial database management systems, so
            : writing a database-enabled webpage with PHP is fairly simple. The
            : most common use of PHP coding is probably as a replacement for CGI
            : scripts.
            :
            : The php package contains the module (often referred to as mod_php)
            : which adds support for the PHP language to Apache HTTP Server.

[root@devserver drupal-8.1.1]#

My phpinfo doesn't list OPcache. It is also not in my php.ini file.

How can I enable it?

Answer 1

Normally this is available as a separate package - I believe this would be something like php55u-opcache on CentOS - source
