This plugin clears OPcache after updating WordPress core, themes, and files.
Unlike other plugins, it is also compatible with WordPress updates made by Linux cron.
cachetool is a little CLI utility that is capable of talking to your PHP-FPM instance in order to clear PHP OPcache.
sudo yum -y install https://extras.getpagespeed.com/release-latest.rpm sudo yum -y install cachetool
The most efficient way to run PHP scripts of any kind in production:
opcache.validate_timestamps set to
In this way, any scripts are not checked for changes. This saves a lot of disk activity for PHP frameworks which have to parse dozens and dozens of scripts on every request.
Set this in your PHP-FPM configuration, or global PHP configuration and when you invoke PHP from cron:
sudo yum -y install wp-cli
Install the plugin using WP-CLI:
wp plugin install opcache-reset --activate
That’s it. Zero configuration is required.
