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/
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》
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：
# yum install perl1.3 perl-fastcgi安装
# 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 install2. 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.
$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #use IP sockets改为$socket = FCGI::OpenSocket( "/var/run/ttlsa.com.perl.sock", 10 ); #use IP sockets3. 配置脚本3.1 fastcgi监听脚本
文件路径：/usr/bin/fastcgi-wrapper.pl
#!/usr/bin/perluse FCGI;use Socket;use POSIX qw(setsid);require 'syscall.ph';&daemonize;#this keeps the program alive or something after exec'ing perl scriptsEND() { } 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 0perlfastcgi="/usr/bin/fastcgi-wrapper.pl"prog=$(basename perl)lockfile=/var/lock/subsys/perl-fastcgistart() { [ -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 esac3.3 设置脚本权限
# chmod a+x /usr/bin/fastcgi-wrapper.pl# chmod a+x /etc/rc.d/init.d/perl-fastcgi4. FastCGI测试
4.1 启动nginx与fastcgi# /usr/local/nginx-1.4.2/sbin/nginx# /etc/init.d/perl-fastcgi start4.2 perl测试文件：
文件路径/data/site/test.ttlsa.com/test.pl
#!/usr/bin/perlprint "Content-type:text/html\n\n";print <<EndOfHTML;<html><head><title>Perl Environment Variables</title></head><body><h1>Perl Environment Variables</h1>EndOfHTMLforeach $key (sort(keys %ENV)) { print "$key = $ENV{$key}<br>\n";}print "</body></html>";5. 访问测试5.1 访问
http://http:test.ttlsa.com/test.pl,出现内容表示OK.
6. 简单压力测试：
6.1 使用tcp/ip方式
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.
![]() perl + fastcgi + tcp-ip
6.2 使用socket方式：
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）。
7. 文件下载perl脚本下载：perl-fastcgi,fastcgi-wrapper.pl,test.perl三个文件
