perl + fastcgi + nginx搭建

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 perl

1.3 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 install

2. nginx虚拟主机配置

server {

??????? listen?????? 81;
??????? 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 sockets

3. 配置脚本

3.1 fastcgi监听脚本
文件路径：/usr/bin/fastcgi-wrapper.pl

#!/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 "fakeexitnrc=".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/plainrnrn");
??????????????????????? 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/plainrnrn");
??????????????? 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 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

# 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

#!/usr/bin/perl

print "Content-type:text/htmlnn";
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

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.

6.2 使用socket方式：

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

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
