What is this:

A "one size fits all" script to interface with spawn-fcgi in a friendly way. It is provided with an example of how to launch PHP, but only needs quick modifying to work with anything that can run as a FastCGI process. Feel free to experiment - this also has been successfully tested with Python WSGI, CGILua, and the like for example.

Note to PHP users on FreeBSD: PHP-FPM support is available from the configure screen - this will allow you to do fine tuning over the FastCGI processes. In my own opinion, you should be using PHP-FPM over this.

Note to everyone else: I have recently switched this over to use UNIX sockets instead of TCP ports; if you want to use a TCP port instead, just type the port into SERVER_SOCKET, and then switch the -s switch to a -p switch in the fcgi_start function :)

File:

/usr/local/etc/rc.d/spawn-fcgi


Usage:

/usr/local/etc/rc.d/spawn-fcgi [(re)start|status|stop]


Run this script on boot (add to /etc/rc.local):

/usr/local/etc/rc.d/spawn-fcgi start

#!/bin/sh
