php – is my OpCache running?

Posted by: admin April 23, 2020 Leave a comment


I am trying to enable opCache on my server (ubuntu 12.04 LTS, running apache 2.4.7 with PHP Version 5.5.10-1+deb.sury.org~precise+1).

Before starting to do anything, I read this highly relevant post which told me that opCache is disabled by default and I have to manually enable it.

I went into php.ini and found that there is no text with opcache.so, also everything related to opcache is commented out. Like this:

; Determines if Zend OPCache is enabled

; Determines if Zend OPCache is enabled for the CLI version of PHP

This is ok, because the person told that it is disabled. But when I consult phpinfo(); it shows me the following (and based on my understanding it tells me that opCache is already used).

enter image description here

So is my opcache enabled and used and how can I see/verify it?

How to&Answers:

Have faith in your phpinfo(), you’ve got the necessary shared module running or it wouldn’t be showing up.

Also, your opcache is indeed enabled, but only for web, not cli. The default for the library is enabled for web so , to disable uncomment the line starting with a semicolon like this:


As noted, for command line php use, the default is disabled, to enable it, uncomment and set to 1


Here is a list of all runtime arguments and there default value for further reference: http://www.php.net/manual/en/opcache.configuration.php

If you want a cool web monitor page for it (like apc.php does for apc) try this:
