Is it possible to run PHP-FPM with Apache or is that a nginx only option?
Looking for ways to use apache and keep .htaccess but gain better php performance like able to take more reqs per sec.
EDIT: I also run nginx as a front-end reverse proxy for static content.
PHP-FPM is PHP FastCGI process manager. Fastcgi is protocol for communication between application server and webserver. FastCGI is supported for all major web servers - apache2, lighttpd, nginx, cherokee, IIS.
For Apache 2.4, you can use mod_proxy_fcgi. Apache 2.4 is recommended because of performance improvements and new super-fast mpm_event engine. For older Apache versions you have to rely on third party mod_proxy_fcgi, because bundled mod_fcgid does not work with externally spawned processes like phpf-fpm.
Yes, It is possible. According to me Nginx is more flexible, light loaded server than Apache. I am personally using Nginx to run php-fpm.
