Apache
- I suppose you don't really have to use separate port for this, but might avoid problems
Listen 127.0.0.1:89 <Virtualhost 127.0.0.1:89> <Location /fpm-status> Require host localhost ProxyPass unix:/run/php/php-fpm.sock|fcgi://localhost:9001 </Location> <Location /fpm-ping> Require host localhost ProxyPass unix:/run/php/php-fpm.sock|fcgi://localhost:9001 </Location> </VirtualHost>
HOWTO
Configuring number of servers
dynamic - the number of child processes are set dynamically based on the following directives: pm.max_children - the maximum number of children that can be alive at the same time.
pm.start_servers - the number of children created on startup. this value must not be less than min_spare_servers and not greater than max_spare_servers.
pm.min_spare_servers - the minimum number of children in 'idle' state (waiting to process). If the number of 'idle' processes is less than this number then some children will be created.
pm.max_spare_servers - the maximum number of children in 'idle' state (waiting to process). If the number of 'idle' processes is greater than this number then some children will be killed.
