perl + fastcgi + nginx搭建

nginx + fastcgi是php下最流行的一套環境了，那perl會不會也有fastcgi呢，當然有，今天來搭建下nginx下perl的fastcgi.性能方面也不亞于php，但是現在web程序php的流行程度perl無法比擬了，性能再好也枉然，但是部分小功能可以考慮使用perl的fastcgi來搞定.進入正題.
1. 準備軟件環境：

nginx：http://www.nginx.org
perl：系統自帶
fastcgi：http://www.cpan.org/modules/by-module/FCGI/
1.1 nginx安裝
這里就不再詳細介紹了~
1.2 perl安裝
一般linux都有自帶perl，可以不用安裝，如果確實沒有，請執行：

# yum install perl

1.3 perl-fastcgi安裝

# 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虛擬主機配置

server {   listen  80;  server_name test.Vevb.com;  #access_log /data/logs/nginx/test.Vevb.com.access.log main;   index index.html index.php index.html;  root /data/site/test.Vevb.com;   location /   {   }   location ~ /.pl$   {   include fastcgi_params;   fastcgi_pass 127.0.0.1:8999;   #fastcgi_pass unix:/var/run/Vevb.com.perl.sock;   fastcgi_index index.pl;  }}

如果想把tcp/ip方式改為socket方式，可以修改fastcgi-wrapper.pl.

$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 ); #use IP sockets

改為

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

3. 配置腳本

3.1 fastcgi監聽腳本
文件路徑：/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 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";   }   }}
