The Stratus CLI can also be used to clear the opcache instead of this method.
If your code deploys use symlinks or you think something is cached in the PHP opcache, you can clear it via the php-fpm port.
On all Stratus sites, the hostname:port is phpfpm:9000.
To use Cachetool, configure these settings in
adapter: fastcgi fastcgi: php-fpm:9000 temp_dir: /srv/tmp
For PHP 7.0.x, download the following file:
wget -c https://github.com/gordalina/cachetool/raw/gh-pages/downloads/cachetool-3.2.1.phar
For PHP 7.1 or 7.2, download:
wget -c http://gordalina.github.io/cachetool/downloads/cachetool.phar
The file must be renamed .cachetool.yml. CacheTool will look for this file in the current directory.
