Load balancing with FastCGI/PHP

Hi there,

How do I configure load balancing for FastCGI/PHP?

I have three lighttpd servers. The main server accepts requests and delegates the requests to either Server1 or Server2. The problem is that the main server is always throwing 500 Internal Error.

Main Server's Log:

2010-11-29 23:33:46: (log.c.166) server started
2010-11-29 23:33:57: (mod_fastcgi.c.3061) got proc: pid: 0 socket: tcp:127.0.0.1:82 load: 1

lighttpd is a FastCGI client, not a FastCGI server. use mod_proxy.

RE: Load balancing with FastCGI/PHP - Added by over 14 years ago

How do I go about setting up a FastCGI server? Are there any compiled implementations around?
I did a bit of googling and didn't find much on setting up a fastcgi server.

All I got is info on how to write a loop to accept FastCGI requests.
