For enabeling extensions you can use the php_admin_value setting for each pool:

php_admin_value[extension] = extension.so

Hi there.

There is no way to restart a single pool. If you change the conf file, send a USR2 
signal to the FPM process. All pool will be restarted. If you really don't want to 
restart other pools, you can safely send a QUIT signal the each pool processes.

btw, this bugs makes me think about adding a gracefull restart of FPM.

Would be great also the possibility to add fpm pools on-the-fly without having to restart fpm (causing a downtime to all pools)

Hi all,

I am playing with fpm and chroot using unix sockets for shared web hosting. There 
is also a problem with recreating a missing socket file which requires a complete 
restart of fpm.

Any news on this request here?

Regards,
Ralph

Currently, the only way to do this is to run multiple PHP-FPM masters, all with a single pool. That way, you have full control over which extensions are loaded and how they're configured and you can restart a single pool without impacting others.

This technique, as well as example configs, is further explained in this blogpost: http://mattiasgeniar.be/2014/04/09/a-better-way-to-run-php-fpm/
