HTTP 504网关在将Dancer2应用程序作为cgi脚本运行时超时

我正在尝试使用Apache将Dancer2应用程序部署为cgi脚本。我跟着instructions in the Dancer2 deployment guide作为cgi脚本运行但是当我尝试在浏览器中访问我的应用程序时,我得到HTTP 504网关超时。

我是PSGI / Plack世界的新手,所以我可以在诊断中离开,但看起来像我要求

http://<hostname>/

来自远程主机,dispatch.cgi启动服务器侦听端口3000,然后只是坐在那里等待输入,直到请求超时。这是我在Apache错误日志中看到的内容:

[Mon Nov 04 09:44:32 2013] [error] [client 128.117.20.57] [ip2map:30142]  core @2013-11-04 09:44:32> Registered Dancer2::Core::DSL__WITH__Dancer2::Plugin::Ajax=HASH(0x3414560) in /var/www/ip2map/public/../lib/ip2map.pm l. 3

[Mon Nov 04 09:45:32 2013] [error] [client 128.117.20.57] Script timed out before returning headers: dispatch.cgi

这是我的Apache配置(Apache v2.2.15):

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName mcmes21.cgd.ucar.edu
    ServerAlias mcmes21
    DocumentRoot /var/www/ip2map/public
    ServerAdmin mcarey@ucar.edu

    <Directory "/var/www/ip2map/public">
       AllowOverride None
       Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
       Order allow,deny
       Allow from all
       AddHandler cgi-script .cgi
    </Directory>

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ /dispatch.cgi$1 [QSA,L]

    ErrorLog  /var/log/httpd/ip2map-error_log
    CustomLog /var/log/httpd/ip2map-access_log common
</VirtualHost>

请注意,我的应用程序在通过mod_proxy与Starman一起提供时使用以下Apache配置正常工作:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName mcmes21.cgd.ucar.edu
    ServerAlias mcmes21

    DocumentRoot /var/www/ip2map

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass        / http://localhost:5000/
    ProxyPassReverse / http://localhost:5000/
</VirtualHost>

有谁知道我如何才能将其作为CGI工作?

注意:我昨天也将这个问题发给了舞者用户邮件列表。

使用以下命令配置Apache以使用mod_perl运行Dancer应用程序。这比CGI快得多。

  1. 安装mod_perl(如果尚未安装):

     sudo apt-get install libapache2-mod-perl2
    
  2. 安装Plack and Dancer,如果尚未安装:

     sudo apt-get install libplack-perl
     sudo apt-get install libdancer-perl
    
  3. 将以下内容添加到apache中的站点配置中(通常在../sites-available中)。在下面的代码段中,我使用/ home / user / dancerapp作为舞者应用程序的绝对路径,并使用'dancerapp.com'作为您的服务器名称。请务必更改为您的应用:

     <VirtualHost *:80>
    
     ServerName dancerapp.com
    
     DocumentRoot /home/user/dancerapp/public
    
     <Location />
       SetHandler perl-script
       PerlResponseHandler Plack::Handler::Apache2
       PerlSetVar psgi_app /home/user/dancerapp/bin/app.pl
       SetEnv DANCER_ENVIRONMENT "production"
     </Location>
    
     <Perl>
       use Plack::Handler::Apache2;
       Plack::Handler::Apache2->preload("/home/user/dancerapp/bin/app.pl");
     </Perl>
    
     </VirtualHost>
    
  4. 请记住重启apache:

      sudo /etc/init.d/apache2 restart
