CGI benutzen

Post by **Giamatti1988** » 2012-01-29 11:33

Hallo liebe gemeinde,

ich habe hier ein naja eher winziges Problem, welches mir wie nen unüberwindbares hinderniss vorkommt.

Ich habe auf meinem VServer reineweg Debian 6 mit Apache2 und php5 installiert.

nun wollt ich aber auch noch CGI benutzen, nur leider hapert es dort ein wenig.

Ich habe in der Apache Config meiner Domain (die ich dazu verwende) die Config insoweit angepasst um CGI zu benutzen darüber.

Code: Select all

<VirtualHost *:80>
  ServerName meinedomain.de.vu 
  ServerAlias *.meinedomain.de.vu 
  ServerAdmin root@meinedomain.de.vu 
  DocumentRoot "/home/www/meinedomain.de.vu/htdocs" 

  ScriptAlias /cgi-bin/ /home/www/meinedomain.de.vu/cgi-bin/ 

  php_admin_value open_basedir "/home/www/meinedomain.de.vu/htdocs:/tmp/" 
  php_admin_flag safe_mode Off 
  ErrorLog "/home/www/meinedomain.de.vu/logs/error.log" 
  
  <Directory /home/www/meinedomain.de.vu/htdocs> 
    Options Indexes FollowSymLinks MultiViews 
    AllowOverride None 
    Order allow,deny 
    allow from all 
  </Directory> 

  <Directory "/home/www/meinedomain.de.vu/cgi-bin/">
    AllowOverride None
    Options +ExecCGI -Includes
    Order allow,deny
    Allow from all
  </Directory> 
</VirtualHost>

so nun habe ich übers web dann das CGI Script aufgerufen und erhalte ein ERROR 500

anhand der Logfiles erhalte ich diese Information

Code: Select all

[Sun Jan 29 11:13:24 2012] [error] [client 91.66.***.***] (13)Permission denied: exec of '/home/www/meinedomain.de.vu/cgi-bin/first.pl' failed
[Sun Jan 29 11:13:24 2012] [error] [client 91.66.***.***] Premature end of script headers: first.pl

so anhand dieser meldung seh ich ja er kann auf irgend etwas nicht zugreifen oder versteh ich dies falsch?

so wenn ich aber das Script per shell abrufe

perl first.pl dann erhalte ich die ausgabe in HTML

Code: Select all

root@vps43010:/home/www/meinedomain.de.vu/cgi-bin# perl first.pl
Content-type: text/html

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

</head>
<body>
<table cellspacing="0" cellpadding="0" border="0">
<tr class="subhead" align="Left"><th>Name</th><th>Value</th></tr>
</table>
</body>
</html>

so nun die Endgültige Frage, wie bekomm ich das nun hin, das ich über den Webbrowser auch eine Ausgabe erhalte, die Vielversprechender ist als die meldung ERROR 500?

Um Aussagen wie Bitte genauer Lesen vorzubeugen, ich habe diese anleitung hier befolgt...

Bitte zunächst mal folgende Ausgaben posten:

Code: Select all

ls -alh /home/www/meinedomain.de.vu/ /home/www/meinedomain.de.vu/cgi-bin/

cat /home/www/meinedomain.de.vu/cgi-bin/first.pl

grep -rin 'script' /etc/apache2

Hier die Ausgabe zum Befehl.:

oke naja was soll man sagen
das einfachste was man machen kann ist die Doofheit siegen lassen xD

nein scherz

habs hinbekommen nun. Scheint wohl der fehler gewesen zu sein das ich die rechte falsch gesetzt habe...

und in der mime.conf vergessen hatte die CGI Scripte zu aktivieren also das (#) davor weg nehmen und apache restarten...

weia

Manchmal sind es halt die einfachsten Dinge, die man übersieht
