[php] PHP FPM - check if running

The documentation on php fpm website says that php fpm is part for coe php as of 5.3.3

I am running 5.3.10, how can i check that it is working correctly? I thought it was a service that ran on a port?

Here is how you can do it with a socket on php-fpm 7

install socat
apt-get install socat

#!/bin/sh

  if echo /dev/null | socat UNIX:/var/run/php/php7.0-fpm.sock - ; then
    echo "$home/run/php-fpm.sock connect OK"
  else
    echo "$home/run/php-fpm.sock connect ERROR"
  fi

You can also check if the service is running like this.

service php7.0-fpm status | grep running

It will return

Active: active (running) since Sun 2017-04-09 12:48:09 PDT; 48s ago

For php7.0-fpm I call:

service php7.0-fpm status

php7.0-fpm start/running, process 25993

Now watch for the good part. The process name is actually php-fpm7.0

echo `/bin/pidof php-fpm7.0`

26334 26297 26286 26285 26282

PHP-FPM is a service that spawns new PHP processes when needed, usually through a fast-cgi module like nginx. You can tell (with a margin of error) by just checking the init.d script e.g. "sudo /etc/init.d/php-fpm status"

What port or unix file socket is being used is up to the configuration, but often is just TCP port 9000. i.e. 127.0.0.1:9000

The best way to tell if it is running correctly is to have nginx running, and setup a virtual host that will fast-cgi pass to PHP-FPM, and just check it with wget or a browser.

in case it helps someone, on amilinux, with php5.6 and php-fpm installed, it's:

sudo /etc/init.d/php-fpm-5.6 status

Assuming you are on Linux, check if php-fpm is running by searching through the process list:

ps aux | grep php-fpm

If running over IP (as opposed to over Unix socket) then you can also check for the port:

netstat -an | grep :9000

Or using nmap:

nmap localhost -p 9000

Lastly, I've read that you can request the status, but in my experience this has proven unreliable:

/etc/init.d/php5-fpm status
