nginx + fastcgi是php下最流行的一套环境了，那perl会不会也有fastcgi呢，当然有，今天来搭建下nginx下perl的fastcgi.性能方面也不亚于php，但是现在web程序php的流行程度perl无法比拟了，性能再好也枉然，但是部分小功能可以考虑使用perl的fastcgi来搞定.进入正题.

1. 准备软件环境：

nginx：http://www.nginx.org
perl：系统自带
fastcgi：http://www.cpan.org/modules/by-module/FCGI/文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

1.1 nginx安装
nginx安装过无数次,这边不在重复安装过程,如果你还没有安装nginx并且不知道怎么安装nginx，那么请先参考之前的文章《nginx安装配置》文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

1.2 perl安装
一般linux都有自带perl，可以不用安装，如果确实没有，请执行：文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

# yum install perl

1.3 perl-fastcgi安装文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

# cd /usr/local/src
# wget http://www.cpan.org/modules/by-module/FCGI/FCGI-0.74.tar.gz
# tar -xzvf FCGI-0.74.tar.gz
# cd FCGI-0.74
# perl Makefile.PL 
# make
# make install

2. nginx虚拟主机配置

server {

        listen       80;
        server_name  test.ttlsa.com;
        #access_log  /data/logs/nginx/test.ttlsa.com.access.log  main;

        index index.html index.php index.html;
        root /data/site/test.ttlsa.com;

        location / 
        {

        }

        location ~ \.pl$ 
        {
            include fastcgi_params;
            fastcgi_pass  127.0.0.1:8999;
            #fastcgi_pass  unix:/var/run/ttlsa.com.perl.sock;
            fastcgi_index index.pl;
        }
}

如果想把tcp/ip方式改为socket方式，可以修改fastcgi-wrapper.pl.文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #use IP sockets
改为
$socket = FCGI::OpenSocket( "/var/run/ttlsa.com.perl.sock", 10 ); #use IP sockets

3. 配置脚本

3.1 fastcgi监听脚本
文件路径：/usr/bin/fastcgi-wrapper.pl文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

#!/usr/bin/perl

use FCGI;
use Socket;
use POSIX qw(setsid);

require 'syscall.ph';

&daemonize;

#this keeps the program alive or something after exec'ing perl scripts
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( "127.0.0.1:8999", 10 ); #use IP sockets
        $request = FCGI::Request( \*STDIN, \*STDOUT, \*STDERR, \%req_params, $socket );
        if ($request) { request_loop()};
            FCGI::CloseSocket( $socket );
}

sub request_loop {
        while( $request->Accept() >= 0 ) {

           #processing any STDIN input from WebServer (for CGI-POST actions)
           $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;
                }
            }

            #running the cgi app
            if ( (-x $req_params{SCRIPT_FILENAME}) &&  #can I execute this?
                 (-s $req_params{SCRIPT_FILENAME}) &&  #Is this file empty?
                 (-r $req_params{SCRIPT_FILENAME})     #can I read this file?
            ){
        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 - ";
                        print "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 = <KID_TO_READ>) { print $s; }
            close KID_TO_READ;
            waitpid($pid, 0);
        } else {
                    foreach $key ( keys %req_params){
                       $ENV{$key} = $req_params{$key};
                    }
                    # cd to the script's local directory
                    if ($req_params{SCRIPT_FILENAME} =~ /^(.*)\/[^\/]+$/) {
                            chdir $1;
                    }

            close(PARENT_WR);
            close(STDIN);
            #fcntl(CHILD_RD, F_DUPFD, 0);
            syscall(&SYS_dup2, fileno(CHILD_RD), 0);
            #open(STDIN, "<&CHILD_RD");
            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 ";
                print "exist or is not executable by this process.\n";
            }

        }
}

3.2 fastcgi自启动服务脚本：文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

文件路径：/etc/rc.d/init.d/perl-fastcgi

#!/bin/sh
#
# nginx – this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /opt/nginx/conf/nginx.conf
# pidfile: /opt/nginx/logs/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

perlfastcgi="/usr/bin/fastcgi-wrapper.pl"
prog=$(basename perl)

lockfile=/var/lock/subsys/perl-fastcgi

start() {
    [ -x $perlfastcgi ] || exit 5
    echo -n $"Starting $prog: "
    daemon $perlfastcgi
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    stop
    start
}

reload() {
    echo -n $”Reloading $prog: ”
    killproc $nginx -HUP
    RETVAL=$?
    echo
}

force_reload() {
    restart
}
rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
        exit 2
    esac

3.3 设置脚本权限文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

# chmod a+x /usr/bin/fastcgi-wrapper.pl
# chmod a+x /etc/rc.d/init.d/perl-fastcgi

4. FastCGI测试

4.1 启动nginx与fastcgi
# /usr/local/nginx-1.4.2/sbin/nginx
# /etc/init.d/perl-fastcgi start

4.2 perl测试文件：
文件路径/data/site/test.ttlsa.com/test.pl文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

#!/usr/bin/perl

print "Content-type:text/html\n\n";
print <<EndOfHTML;
<html><head><title>Perl Environment Variables</title></head>
<body>
<h1>Perl Environment Variables</h1>
EndOfHTML

foreach $key (sort(keys %ENV)) {
    print "$key = $ENV{$key}<br>\n";
}

print "</body></html>";

5. 访问测试

5.1 访问文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

http://http:test.ttlsa.com/test.pl,出现内容表示OK.文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

6. 简单压力测试：
6.1 使用tcp/ip方式文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

ab -n 1000 -c 10 http://test.ttlsa.com/test.pl

他是在是太慢了，只好用10个并发，共计100个请求来测试.文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

perl + fastcgi + tcp-ip

6.2 使用socket方式：文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

ab -n 100000 -c 500 http://test.ttlsa.com/test.pl

perl + fastcgi + socket

很奇怪，使用tcp/ip方式，每秒就140多个请求，而使用socket方式却有5800个请求/秒。差距不是一般的大。顺便测试了一下php的fastcgi，大概请求在3000（tcp/ip方式），4800（socket方式）。文章源自运维生存时间-https://www.ttlsa.com/nginx/perl-fastcgi-nginx/

php-fpm开启。。nginx如何去调用php-fpm来解释cgi文件，我现在把cgi文件交给php-fpm处理，页面就会出现cgi文件的源码

  @ Ryan 这边是Perl的fastcgi与php-fpm无关

请问访问test.pl为什么：
504 Gateway Time-out

nginx/1.4.1 (Ubuntu)
