Ich bin gerade dabei, ein Produktions-Codeigniter-Projekt auf einen neuen Server zu migrieren. Das aktuelle Setup funktioniert seit fast einem Jahr einwandfrei, aber beim Wechsel zum neuen LAMP-Stack stoße ich auf ein seltsames Problem beim Umschreiben der index.php zurück in die URL.
Mein erster Gedanke war, dass diese Frage besser zu SO passen würde, jedoch ist der Code bei beiden Instanzen genau derselbe und beide führen Debian 7.5 und Apache 2.2.22 aus, was mich glauben lässt, dass es sich um einen Unterschied in der Serverkonfiguration handelt, der mir nicht bewusst ist.
Dies ist das mod_rewrite ist wie folgt
RewriteEngine On
RewriteBase /bookings/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Wie gesagt, dies hat im aktuellen Setup gut funktioniert, auf dem neuen Server werden Links von der Basisseite jedoch immer auf dieselbe Seite umgeschrieben.
Ich habe die Umschreibeprotokollierung für beide Server aktiviert und der neue Server führt einen zusätzlichen Umschreibeschritt aus, den ich nicht erklären kann.

Wie oben zu sehen ist, führt der neue Server die anfängliche Umleitung korrekt aus, aber dann gibt es den zusätzlichen Abschnitt, der immer index.php zurückgibt. Irgendeine Idee, was die Ursache dafür sein könnte? Ich bin nicht einmal 100 % sicher, dass das Problem bei mod_rewrite liegt. Mir sind die Optionen ausgegangen und ich weiß nicht viel über mod_rewrite
Antwort1
Ich habe keine Ahnung, woran das lag, aber ich habe ein neues Image des Servers erstellt, die Dienste neu installiert und das Problem war behoben.
