So, you want to use CGI. OK! Let’s make this as simple as possible for you.
There are packages for Debian and Ubuntu now. Simply type
aptitude install fcgiwrap
Then, have a look at /usr/share/doc/fcgiwrap/README.Debian. There’s an example configuration at /usr/share/doc/fcgiwrap/examples/nginx.conf.
What I did was creating a local copy of the example configuration (so it does not get overwritten upon updates)
cp /usr/share/doc/fcgiwrap/examples/nginx.conf /etc/nginx/fcgiwrap.conf
and add it to the the site’s configuration in the “server” section with
# fast cgi support
include /etc/nginx/fcgiwrap.conf;
After installing the package, also have a look at the ngx_http_fastcgi_module documentation or the FastCGI Example.
The first step here is to install this stuff.
If you’re on an apt based system:
aptitude install git-core build-essential libfcgi-dev autoconf libtool automake
Get the source:
cd /usr/local/src/
git clone git://github.com/gnosek/fcgiwrap.git
Compile this:
cd /usr/local/src/fcgiwrap
autoreconf -i
./configure
make
mv fcgiwrap /usr/local/bin/
#!/usr/bin/perl
use strict;
use warnings FATAL => qw( all );
use IO::Socket::UNIX;
my $bin_path = '/usr/local/bin/fcgiwrap';
my $socket_path = $ARGV[0] || '/tmp/cgi.sock';
my $num_children = $ARGV[1] || 1;
close STDIN;
unlink $socket_path;
my $socket = IO::Socket::UNIX->new(
Local => $socket_path,
Listen => 100,
);
die "Cannot create socket at $socket_path: $!\n" unless $socket;
for (1 .. $num_children) {
my $pid = fork;
die "Cannot fork: $!" unless defined $pid;
next if $pid;
exec $bin_path;
die "Failed to exec $bin_path: $!\n";
}
Don’t forget chmod +x /etc/init.d/fcgiwrap.
I decided not to try to make an overly complicated init script and sit with the simple one.
I just added sudo -u www-data /etc/init.d/fcgiwrap to /etc/rc.local before the exit 0 line.
The sudo command will launch the fcgiwrapper init script as the www-data user.
The script bings a listener thread to /tmp/cgi.sock.
This is what you need to use in fastcgi_pass: fastcgi_pass unix:/tmp/cgi.sock;
