Load balancing FastCGI

Run this command on a worker

spawn-fcgi -p 8081 -a 192.168.2.100 -f /usr/bin/php-cgi -u lighttpd -g lighttpd -C 5 -P /var/run/spawn-fcgi-8081.pid

Don’t forget to open up the right port (8081 in the example) and monitor the processes (say restart when it dies)

Bind to a socket

spawn-fcgi -s /tmp/php-fastcgi-ext.sock -f /usr/bin/php-cgi -u lighttpd -g lighttpd -C 5 -P /var/run/spawn-fcgi.pid

Bind to an IP:port

spawn-fcgi -p 8081 -a 192.168.2.100 -f /usr/bin/php-cgi -u lighttpd -g lighttpd -C 5 -P /var/run/spawn-fcgi-8081.pid

Need also to turn on lighttpd (service lighttpd start) so reporter can get status on this server directly (through port 80)

Using an external fcgi in lighttpd.conf to load balance only a specific file

fastcgi.server = (
"/index.php"=>
(
 ("socket"=>"/tmp/php-fastcgi.socket",
  "bin-path"=>"/usr/bin/php-cgi",
  "min-procs"=>2,
  "max-procs"=>4,
  "bin-environment"=>("PHP_FCGI_CHILDREN"=>"10","PHP_FCGI_MAX_REQUESTS"=>"5000")
 ),
 ("host"=>"192.168.2.100",
  "port"=>8081,
  "check-local"=>"disable",
  "disable-time"=>30
 )
),
".php"=>
(
 ("socket"=>"/tmp/php-fastcgi.socket",
  "bin-path"=>"/usr/bin/php-cgi",
  "min-procs"=>1,
  "max-procs"=>2,
  "bin-environment"=>("PHP_FCGI_CHILDREN"=>"5","PHP_FCGI_MAX_REQUESTS"=>"1000")
 )
