Wie verhindere ich, dass Apache2 versucht, eine Datei als Skript auszuführen?

Im Grunde folgte ich diesem Leitfaden über die iptraf-Überwachung und rrdtool zu dem Buchstaben. Ich habe es wie üblich für CGI-Skripte in /usr/lib/cgi-bin/ eingefügt. Wenn ich es dann in einem Browser besuche, scheinen die Bilder, die es erstellt, defekt zu sein. Ich habe die Berechtigungen für Debugging-Zwecke vorübergehend auf 777 gesetzt. Ich denke, Apache2 versucht, die PNG-Dateien als Skript auszuführen. Wie kann ich das verhindern? Unten finden Sie meine Konfigurationsdateien. Danke im Voraus!

Oh. Und ich renne als root.

# DefaultType is the default MIME type the server will use for a document

# keep browsers from trying to display binary files as though they are
# text.
#
# It is also possible to omit any default MIME type and let the
# client's browser guess an appropriate action instead. Typically the
# browser will decide based on the file's extension then. In cases
# where no good assumption can be made, letting the default MIME type

Verschieben Sie Ihre Bilder aus dem Ordner /usr/lib//cgi-bin/ und platzieren Sie sie innerhalb von /var/www/ Aktualisieren Sie Ihre Pfade entsprechend.

Jedes Mal, wenn Sie versuchen, auf eine Datei im cgi-bin -Pfad zuzugreifen, wird erwartet, dass der Inhalt durch Ausführen dieser Datei generiert wird.

Wir bedienen eine unserer kleinen Websites von einer NAS-CIFS-Freigabe, so dass die Unix-Modi alle aus einem Guss bestehen. Alles ist Modus-ausführbar und nichts kann mit chmod geändert werden.

Ich habe festgestellt, dass mein Problem das ScriptAlias war, das Apache befahl, alles auszuführen, sogar Bilder. Ich dachte, <Directory ...> -ExecCGI... für das img -sub-Verzeichnis könnte eine gute Idee sein, hat aber nicht funktioniert.

Ich habe mein Problem behoben, indem ich die Bilder unter dem bin-dir (jetzt sind sie Schwestern) verschoben habe und ein separates Alias (kein Skript!) und <Directory...> hinzugefügt habe.
