Lighttpd + Php5

daltocli · 2007-03-26 17:53:31

Hello, I have recently had a VPS installed with Arch Linux, loving it as a server OS so far.

I've come across an issue with LIGHTTPD with PHP5... I keep getting 500ISE errors. The infos I have at hand:

[root@moss ~]# /var/log/lighttpd/error.log

Any ideas? I've removed some bits for security reasons.

When php5 (as far as I tested php 5.2.1) is compiled with fast-cgi capabilities. When you start it as a normal binary without any cmdline args, even though you would set the PHP_FCGI_CHILDREN environment variable to some values it doesn't fork any children.
When you instead execute it with the -b option (listen to ip:port, like ./php -b 127.0.0.1:12345) it accepts that same environment variable and forks the correct number of worker children processes.
Just what I saw by strace. No idea if it helps you. I didn't study the php manuals closer.
Though.. I read on the net complaints that the php fcgi implementation is not very fcgi, more like imitating the apache sapi mod_php.

just my random ramblings

Hmm... I gave that a try, I still get the same problem! Thanks for the suggestion though, I'm going to keep that bit in there

You need to install php-cgi from extra since the php package does not provide cgi functionality on its own. In your lighttpd.conf you need to call `php-cgi' instead of `php':

...

$HTTP["host"] == "localhost" {
    server.document-root = "/home/abc/html/"
    server.indexfiles = ( "index.html","index.htm","index.shtml","index.shtm","index.stm","index.php","index.cgi","index.pl","index.sh","index.py","index.rb" )
    fastcgi.server = (
        ".php" => (
            "localhost" => (
                "socket"   => "/tmp/php-fastcgi.socket",
                "bin-path" => "/usr/bin/php-cgi -c /etc/php.ini",
                "bin-environment" => (
                    "PHP_FCGI_CHILDREN"     => "32",
                    "PHP_FCGI_MAX_REQUESTS" => "5000"
                )
            )
        )
    )
}

...

Also I think the "-c /etc/php.ini" commandline option is redundant since /etc/php.ini is the default for php to look at.
