基于CentOS搭建nginx+perl的perl平台

基于CentOS搭建nginx+perl的perl平台
1.nginx安装

./configure \
     "--user=www" \
     "--group=www" \
     "--prefix=/usr/local/nginx/" \
     "--with-http_stub_status_module" \
     "--with-http_ssl_module" \
     "--with-md5=/usr/lib" \
     "--with-sha1=/usr/lib"
make
make install

2.perl安装

#yum install perl*
#perl -MCPAN -e 'install FCGI'
#perl -MCPAN -e 'install FCGI::ProcManager'

3.fcgi脚本配置
3.1.新建脚本:

#vi /usr/local/bin/cgiwrap-fcgi.pl

写入:

#!/usr/bin/perl -w 
use FCGI; 
use Socket; 
use FCGI::ProcManager; 
sub shutdown { FCGI::CloseSocket($socket); exit; } 
sub restart  { FCGI::CloseSocket($socket); &main; } 
use sigtrap 'handler', \&shutdown, 'normal-signals'; 
use sigtrap 'handler', \&restart,  'HUP'; 
require 'syscall.ph'; 
use POSIX qw(setsid); 

#&daemonize; we don't daemonize when running under runsv 
#this keeps the program alive or something after exec'ing perl scripts 
END()   { } 
BEGIN() { }

    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;

        } 
    } 
}

给予执行权限:

#chmod +x /usr/local/bin/cgiwrap-fcgi.pl

3.2.启动管理脚本

#vi /usr/local/bin/perl-fcgi

写入代码:

#!/bin/sh
#perl-fcgi start shell
#by hamgua(哈密瓜)
#bbs:http://bbs.linuxtone.org
perl_start() {
  /usr/local/bin/cgiwrap-fcgi.pl > /dev/null 2>&1 & 
}

perl_stop() {
  for i in ` ps aux|grep perl|grep -v grep|awk '{print $2}'`; do kill -9 $i; done
}
perl_restart() {
  for i in ` ps aux|grep perl|grep -v grep|awk '{print $2}'`; do kill -9 $i; done > /dev/null 2>&1
  /usr/local/bin/cgiwrap-fcgi.pl > /dev/null 2>&1 &
}

case "$1" in
  start)
        echo -n "Starting perl-fcgi: "
        perl_start
        ps aux|grep perl-fcgi-pm|grep -v "grep"|awk '{print $2}' > /dev/null 2>&1
  if [ "$?" != 0 ] ; then
   echo " failed"
   exit 1
  else
          echo " ok"
  fi
        ;;
  stop)
        echo -n "Stopping perl-fcgi: "
        perl_stop
        ps aux|grep perl-fcgi-pm|grep -v "grep"|awk '{print $2}' > /dev/null 2>&1
  if [ "$?" != 0 ] ; then
   echo " ok"
   exit 1
  else
          echo " failed"
  fi
        ;;
  restart)
        echo -n "Restarting perl-fcgi:"
        perl_stop
        sleep 1
        perl_start
        echo " ok"
        ;;
  *)
          echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2
          exit 3
        ;;
esac

exit 0

给予执行权限:

#chmod u+x /usr/local/bin/perl-fcgi

4.nginx配置

server
       {
               listen       80;
               server_name  perl.linuxtone.org;
               index index.html index.pl index.perl index.cgi;
               root /data/www/wwwroot/perl;
        
               location ~ .*\.(pl|perl|cgi)?$
               {
                       fastcgi_pass 127.0.0.1:9002;
                       fastcgi_index index.cgi;
                       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                       include   fastcgi_params;
               } 
     }

最后重启nginx

/etc/init.d/nginx restart

收工
