Question

Enable PHP 5.5 Opcache on Ubuntu 14.04 with Nginx and PHP-FPM

Making the switch from APC to Opcache now that it’s standard with Ubuntu 14.04. All the tutorials seemed to be on Apache so thought I’d share what I did. The first change and restarting php I believe is all you need to do while the other changes are for performance and will vary based on your needs. If others have recommendations or additional advice please pipe in!

sudo vim /etc/php5/fpm/php.ini

Change: ;opcache.enable=0 to opcache.enable=1

Change: ;opcache.memory_consumption=64 to opcache.memory_consumption=128

Change: ;opcache.max_accelerated_files=2000 to opcache.max_accelerated_files=4000

Change: ;opcache.revalidate_freq=2 to opcache.revalidate_freq=60

Then restart: sudo service php5-fpm restart

Hi, I have opcache up and running but there is no files cached. There is a lot of misses and blacklist misses but no cached keys and no cached scripts. What could be wrong?
