nginx用fastcgi方式运行perl脚本

首先,安装Perl的FastCGI模块:

#wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.67.tar.gz
#tar zxvf FCGI-0.67.tar.gz
#cd FCGI-0.67
# perl Makefile.PL
#make && make install


其实也可以用这种方法:

#perl -MCPAN -e ‘install FCGI’

然后,配置Perl的FastCGI脚本

#!/usr/bin/perl
use FCGI;
use Socket;
use POSIX qw(setsid);
require ’syscall.ph’;
&daemonize;
END() { } BEGIN() { }
*CORE::GLOBAL::exit = sub { die “fakeexit\nrc=”.shift().”\n”; };
eval q{exit};
if ($@) {
exit unless $@ =~ /^fakeexit/;
};
&main;
sub daemonize() {
chdir ‘/’ or die “Can’t chdir to /: $!”;
defined(my $pid = fork) or die “Can’t fork: $!”;
exit if $pid;
setsid or die “Can’t start a new session: $!”;
umask 0;
}
sub main {
$socket = FCGI::OpenSocket( “/tmp/perl_fastcgi.sock”, 10 );
$request = FCGI::Request( \*STDIN, \*STDOUT, \*STDERR, \%req_params, $socket );
if ($request) { request_loop()};
FCGI::CloseSocket( $socket );
}
sub request_loop {
while( $request->Accept() >= 0 ) {
$stdin_passthrough =”;
$req_len = 0 + $req_params{’CONTENT_LENGTH’};
if (($req_params{’REQUEST_METHOD’} eq ‘POST’) && ($req_len != 0) ){
my $bytes_read = 0;
while ($bytes_read < $req_len) {
my $data = ”;
my $bytes = read(STDIN, $data, ($req_len – $bytes_read));
last if ($bytes == 0 || !defined($bytes));
$stdin_passthrough .= $data;
$bytes_read += $bytes;
}
}
if ( (-x $req_params{SCRIPT_FILENAME}) &&
(-s $req_params{SCRIPT_FILENAME}) &&
(-r $req_params{SCRIPT_FILENAME})
){
pipe(CHILD_RD, PARENT_WR);
my $pid = open(KID_TO_READ, “-|”);
unless(defined($pid)) {
print(”Content-type: text/plain\r\n\r\n”);
print “Error: CGI app returned no output – Executing $req_params{SCRIPT_FILENAME} failed !\n”;
next;
}
if ($pid > 0) {
close(CHILD_RD);
print PARENT_WR $stdin_passthrough;
close(PARENT_WR);
while(my $s = ) { print $s; }
close KID_TO_READ;
waitpid($pid, 0);
} else {
foreach $key ( keys %req_params){
$ENV{$key} = $req_params{$key};
}
if ($req_params{SCRIPT_FILENAME} =~ /^(.*)\/[^\/]+$/) {
chdir $1;
}
#
close(PARENT_WR);
close(STDIN);
syscall(&SYS_dup2, fileno(CHILD_RD), 0);
exec($req_params{SCRIPT_FILENAME});
die(”exec failed”);
}
}
else {
print(”Content-type: text/plain\r\n\r\n”);
print “Error: No such CGI app – $req_params{SCRIPT_FILENAME} may not exist or is not executable by this process.\n”;
}
#
}
}

将权限改为可执行,并执行之。

配置nginx.conf,使之支持perl脚本

location ~* .*\.pl$
{
include pl.conf;
}

编辑pl.conf

fastcgi_pass unix:/tmp/perl_fastcgi.sock;
fastcgi_index index.pl;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_read_timeout 60;

然后重启nginx.

nginx下测试

test.pl 放在站点的根目录

code:

#!/usr/bin/perl -w
print “Content-type: text/plain\r\n\r\n”;#发送头信息
print “test”;

记得一定要给nginx发送头信息 不然会报504错误的。
