PHP integration and configuration in lighttpd 1.5.0 has changed: mod_fastcgi isn’t used any more, you need mod_proxy_backend_fastcgi instead; and lighty won’t launch the PHP processes, you’ll have to start them using the spawn-fcgi program.
In order to setup mod_proxycore for use with PHP, this is the bare minimum configuration (put it in lighttpd.conf, or conf-enabled/php.conf):
server.modules += ( "mod_proxy_core", "mod_proxy_backend_fastcgi" )
$PHYSICAL["existing-path"] =~ ".php$" {
proxy-core.allow-x-sendfile = "enable"
proxy-core.protocol = "fastcgi"
proxy-core.backends = ( "unix:/tmp/php-fastcgi.sock" )
proxy-core.max-pool-size = 16
}
And for the PHP fast-cgi processes, just run or prepare an init.d script that runs the following command:
/usr/bin/spawn-fcgi -s /tmp/php-fastcgi.sock -f /usr/bin/php-cgi -u www-data -g www-data -C 5 -P /var/run/spawn-fcgi.pid
