如何在apache2上执行Rebol CGI脚本

Question

我正在尝试运行一个Rebol CGI脚本，在一个运行在GNU/Linux Debian稳定机器上的apache2服务器上。

这是我的Rebol脚本:

  # pierre@autan: ~$        < 2013_05_29__17_35_22 >
dog /usr/lib/cgi-bin/test.cgi
#!/usr/bin/rebol -cs
REBOL []
print "Content-type: text/html^/"
print "coucou! (signé: Rebol)"

失败:

  # pierre@autan: ~$        < 2013_05_29__17_21_18 >
lynx http://127.0.0.1/cgi-bin/test.cgi

的回报:

                                                       500 Internal Server Error
                             Internal Server Error
   The server encountered an internal error or misconfiguration and was
   unable to complete your request.
   Please contact the server administrator, webmaster@localhost and inform
   them of the time the error occurred, and anything you might have done
   that may have caused the error.
   More information about this error may be available in the server error
   log.

日志显示:

###ROOT### < 29/05/2013 17:02:45 >   root@autan:/# 
tail -1 /var/log/apache2/error.log
[Thu May 30 15:04:23 2013] [error] [client 127.0.0.1] Premature end of script headers: test.cgi

阅读文档(http://httpd.apache.org/docs/trunk/fr/howto/cgi.html)后，我可以成功运行这个Perl脚本:

  # pierre@autan: ~$        < 2013_05_29__17_35_22 >
dog /usr/lib/cgi-bin/testpl.cgi
#!/usr/bin/perl
print "Content-type: text/htmlnn";
print "coucou! (signé: Perle)";

现在，我想知道Rebol脚本出了什么问题…

我检查了几件事:

Rebol可执行文件的路径是正确的:我可以在不显式调用解释器的情况下直接从shell启动脚本:

  # pierre@autan: ~$        < 2013_05_30__14_07_36 >
/usr/lib/cgi-bin/test.cgi 
Content-type: text/html

coucou! (signé: Rebol)

对我来说，执行权似乎很好;它们对于两个文件是相同的:

  # pierre@autan: ~$        < 2013_05_29__17_35_22 >
ll /usr/lib/cgi-bin/test*.cgi
-rwxr-xr-x 1 root root 97 mai   29 09:28 /usr/lib/cgi-bin/test.cgi
-rwxr-xr-x 1 root root 87 mai   29 09:26 /usr/lib/cgi-bin/testpl.cgi

Rebol可执行文件的执行权对我来说似乎很好:

  # pierre@autan: ~$        < 2013_05_30__14_07_36 >
ll /usr/bin/rebol 
-rwxr-xr-x 1 root root 1215652 déc.  30 22:50 /usr/bin/rebol

我使用REBOL/View 2.7.8.4.2 2-Jan-2011.

下面是我修改的apache2配置文件:

###ROOT### < 29/05/2013 17:20:12 >   root@autan:/etc/apache2/conf.d# 
dog /etc/apache2/conf.d/httpd.conf 
#ScriptAlias magic/cgi-bin/ /var/www/magic/cgi-bin/
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
AddHandler cgi-script .cgi
Options
AddHandler magic .rhtml 
Action magic /cgi-bin/magic.cgi
<Directory "/var/www/magic/cgi-bin/">
        AllowOverride None
        Options ExecCGI MultiViews SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
</Directory>
<Directory "/usr/lib/cgi-bin/">
        AllowOverride None
        Options ExecCGI MultiViews SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
</Directory>

注意我对apache的配置一点也不熟悉。

任何想法?

Answer 1

您尝试过使用Rebol/Core版本吗?

Rebol/View需要访问图形系统，即使它只是打印文本，也许这是不可能通过Apache启动的。

(你会得到一个错误，如果你启动Rebol/View在文本控制台，例如)

为了完整起见，我想我还是把解决方案放在这里为好。我只是听从了英戈的建议。下面是我的终端的哑副本，显示了所有步骤:

lynx http://127.0.0.1/cgi-bin/test.cgi

   coucou! (signé: Rebol)

=>成功了!

我不想让core作为我默认的Rebol解释器，这就是为什么我更喜欢让它显式命名为rebol_core。这样/usr/bin/rebol仍然是rebol/view解释器。

非常感谢，Ingo!
