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
perl:系统自带
fastcgi
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 80; server_name test.jb51.net; #access_log /data/logs/nginx/test.jb51.net.access.log main; index index.html index.php index.html; root /data/site/test.jb51.net; location / { } location ~ \.pl$ { include fastcgi_params; fastcgi_pass 127.0.0.1:8999; #fastcgi_pass unix:/var/run/jb51.net.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
$socket = fcgi::opensocket( "/var/run/jb51.net.perl.sock", 10 ); #use ip sockets
3. 配置脚本
3.1 fastcgi监听脚本
文件路径:/usr/bin/fastcgi-wrapper.pl
#!/usr/bin/perl use fcgi; use socket; use posix qw(setsid); require 'syscall.ph'; &daemonize; #this keeps the program alive or something after exec'ing perl scripts end() { } begin() { } *core::global::exit = sub { die "fakeexit\nrc=".shift()."\n"; }; eval q{exit}; if ($@) { 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 =) { 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 - $req_params{script_filename} may not "; print "exist or is not executable by this process.\n"; } } }
3.2 fastcgi自启动服务脚本:
文件路径:/etc/rc.d/init.d/perl-fastcgi
文件路径:/etc/rc.d/init.d/perl-fastcgi
#!/bin/sh # # nginx – this script starts and stops the nginx daemon # # chkconfig: - 85 15 # description: nginx is an http(s) server, http(s) reverse \ # proxy and imap/pop3 proxy server # processname: nginx # config: /opt/nginx/conf/nginx.conf # pidfile: /opt/nginx/logs/nginx.pid # source function library. . /etc/rc.d/init.d/functions # source networking configuration. . /etc/sysconfig/network # check that networking is up. [ "$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.jb51.net/test.pl
#!/usr/bin/perl print "content-type:text/html\n\n"; print <perl environment variables perl environment variables
endofhtml foreach $key (sort(keys %env)) { print "$key = $env{$key}
\n"; } print "
