Apache2 + PHP5-CGI + mod_suphp = Segmentation Fault

[blaue0]

Ich habe Apache2, PHP5, mod_suphp wie folgt auf Gentoo installiert:

Code: Select all

[ebuild   R   ] net-www/apache-2.0.54-r14  +apache2 -debug -doc -ldap -mpm-leader -mpm-peruser +mpm-prefork -mpm-threadpool -mpm-worker -no-suexec (-selinux) +ssl -static-modules -threads 0 kB

Danach habe ich in /etc/conf.d/apache -D SUPHP eingefügt, was folgendes Configfile hinzufügt:

Code: Select all

<IfDefine SUPHP>
        <IfModule !mod_suphp.c>
                LoadModule suphp_module modules/mod_suphp.so
        </IfModule>

        <IfModule mod_mime.c>
                AddType application/x-httpd-php   .php
                AddType application/x-suphp-cgi   .cgi .pl
        </IfModule>

        AddHandler x-httpd-php   .php
        AddHandler x-suphp-cgi   .cgi .pl

        suPHP_Engine on

        <Location />
                SuPHP_AddHandler x-httpd-php
                SuPHP_AddHandler x-suphp-cgi
        </Location>

        # if you're using owner mode comment the following line
        SuPHP_UserGroup apache apache

        AddDirectoryIndex index.php index.php5 index.php4 index.php3 index.phtml
</IfDefine>

Versuche ich nun eine PHP Seite anzuzeigen, geschieht folgendes:

Code: Select all

[Thu Sep 08 13:51:08 2005] [notice] child pid 24731 exit signal Segmentation fault (11)

die /etc/suphp.conf schaut so aus:

Code: Select all

Was läuft da falsch?!

[Roger Wilco]

Lädst du auch mod_php? Mit dem USE-Flag apache2 wird dieses nämlich zumindest mal installiert.

[blaue0]

Nein mod_php ist nicht geladen. Installiert hab ich es nur, weil ich es aus Aushilfslösung benötige.

[Roger Wilco]

Was für eine MPM setzt du im Apache ein?

[blaue0]

Code: Select all

[ebuild   R   ] net-www/apache-2.0.54-r14  +apache2 -debug -doc -ldap -mpm-leader -mpm-peruser +mpm-prefork -mpm-threadpool -mpm-worker -no-suexec (-selinux) +ssl -static-modules -threads 0 kB 

Den mpm-prefork

[Roger Wilco]

Hm, seltsam. Der Apache schmiert nur ab, wenn er ein PHP-Skript parsen soll?
Wenn du die Auswertung nicht scheust, versuche mal strace auf den Apache-Prozess loszulassen. Ansonsten gehen mir langsam die Ideen aus.
