Using Sqreen with PHP FPM pools⚓ PHP FPM pools allow many PHP FPM processes to use independant configurations. Enabling Sqreen for all pools⚓ This is the default behavior. After completion of the Sqreen setup (including launching sqreen-installer), Sqreen protects all the FPM pools. Enabling Sqreen for a limited number of pools⚓ First, deactivate Sqreen globally in the FPM global configuration. For this, remove the token declaration from the file /etc/php/your PHP version/fpm/conf.d/50-sqreen.ini: sqreen.token = 'your token' The token declaration is removed from the global configuration in order to be moved to pool specific configuration. Then specify you want Sqreen to be disabled: sqreen.disable = 1 The next step is to activate Sqreen for the pool you need. Let's assume this pool is configured in the file /etc/php/7.0/fpm/pool.d/my.conf, then let's add the following lines: php_value[sqreen.disable] = 0 php_value[sqreen.token] = 'my token' Finally, the PHP FPM process need to be restarted.
