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. Has to be at least as high as pm.max_spare_servers
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.
FAQ
error messages
pm.min_spare_servers(3) and pm.max_spare_servers(7) cannot be greater than pm.max_children(5)
Obviously, pm.max_children has to be at least as high as pm.max_spare_servers
