PHP not working with SSL

    Hi all,

    I have a problem with php not working with ssl.
    I followed the Perfect Server setup for opensuse 10.3 and installed ispconfig Version: 2.2.21.
    This is a very nice tutorial, very well done.
    I have SSL working for html files, no errors, but it won't work for php.
    When requesting php files through HTTPS, the php is not executed and the server sends the php file to the client and php code is displayed in the browser.
    So,
    http://somedomain/index.html
    works ok,
    https://somedomain/index.html
    works ok,
    http://somedomain/index.php
    works ok,
    https://somedomain/index.php
    does not work.

    I have double checked the settings in ispconfig.
    I have double checked the settings for the Perfect Server opensuse 10.3.
    I tried a home made ssl certificate.
    I am now using a single site certificate from Comodo.
    I am not trying to share the certificate with other domains.
    The SSL port is 443.
    I do not have more than one virtual host on this port.

    I have tried quite a few modifications to the various config files.
    I can find no errors in the log files.
    At this point I'm stumped.

    Any errors in Apache's error log or the web site's error log?
    What's in Vhosts_ispconfig.conf?

    Thank you for your reply.

    The only error I can find is in the /var/log/apache2/error_log when I restart apache:

    [Wed Oct 22 09:22:29 2008] [notice] caught SIGTERM, shutting down

    The certificate still works and gives me the golden padlock.
    These are my test urls.

    http://bestamericagifts.com/test/index.html
    http://bestamericagifts.com/test/index.php
    https://bestamericagifts.com/test/index.html
    https://bestamericagifts.com/test/index.php

    They all work except for the last one.
    Is it possible that the above error could cause php not to work for SSL?


    Here is the conf file you requested.

    Is that all that is in Vhosts_ispconfig.conf? I don't see an SSL vhost there...

    Yes, that is all that is in Vhosts_ispconfig.conf.
    There is an ssl vhost in /etc/apache2/vhosts.d/bestamericagifts.conf, here is that file:

    # Template for a VirtualHost with SSL
    # Note: to use the template, rename it to /etc/apache2/vhost.d/yourvhost.conf.
    # Files must have the .conf suffix to be loaded.
    #
    # See /usr/share/doc/packages/apache2/README.QUICKSTART for further hints
    # about virtual hosts.

    # NameVirtualHost statements should be added to /etc/apache2/listen.conf.

    #
    # This is the Apache server configuration file providing SSL support.
    # It contains the configuration directives to instruct the server how to
    # serve pages over an https connection. For detailing information about these
    # directives see <URL:http://httpd.apache.org/docs-2.2/mod/mod_ssl.html>
    #
    # For the moment, see <URL:http://www.modssl.org/docs/> for this info.

    # This exports the standard SSL/TLS related `SSL_*' environment variables.
    # Per default this exportation is switched off for performance reasons,
    # because the extraction step is an expensive operation and is usually
    # useless for serving static content. So one usually enables the
    # exportation for CGI and SSI requests only.
    # o CompatEnvVars:
    # This exports obsolete environment variables for backward compatibility

    # and no other module can change it.

    # SSL Protocol Adjustments:
    # The safe and default but still SSL/TLS standard compliant shutdown
    # approach is that mod_ssl sends the close notify alert but doesn't wait for
    # the close notify alert from client. When you need a different shutdown
    # approach you can use one of the following variables:
    # o ssl-unclean-shutdown:
    # This forces an unclean shutdown when the connection is closed, i.e. no
    # SSL close notify alert is send or allowed to received. This violates
    # the SSL/TLS standard but is needed for some brain-dead browsers. Use
    # this when you receive I/O errors because of the standard approach where
    # mod_ssl sends the close notify alert.
    # o ssl-accurate-shutdown:
    # This forces an accurate shutdown when the connection is closed, i.e. a
    # SSL close notify alert is send and mod_ssl waits for the close notify
    # alert of the client. This is 100% SSL/TLS standard compliant, but in
    # practice often causes hanging connections with brain-dead browsers. Use
    # this only for browsers where you know that their SSL implementation
    # works correctly.
    # Notice: Most problems of broken clients are also related to the HTTP
    # keep-alive facility, so you usually additionally want to disable
    # keep-alive for those clients, too. Use variable "nokeepalive" for this.
    # Similarly, one has to force some clients to use HTTP/1.0 to workaround
    # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
    # "force-response-1.0" for this.
    SetEnvIf User-Agent ".*MSIE.*" \

    I made some changes to the bestamericagifts.conf file and fixed the previous warning on apache startup:

    [warn] RSA server certificate CommonName (CN) `bestamericagifts.com' does NOT match server name!?

    I no longer get this warning on startup.

    You must create the SSL vhost in ISPConfig. Please enable SSL for www.bestamericagifts.com and go to the SSL tab and create a certificate.

    I tried that twice, didn't work.
    After I tried it, I checked to see which files had been modified like this:

    find / -name "*.conf" -mmin -120 -print
    /etc/proftpd_ispconfig.conf
    /etc/apache2/httpd.conf
    /etc/apache2/sysconfig.d/global.conf
    /etc/apache2/sysconfig.d/loadmodule.conf
    /etc/apache2/sysconfig.d/include.conf
    /etc/apache2/vhosts/Vhosts_ispconfig.conf

    Then I opened each file and I couldn't see any changes that had anything to do with ssl. I was also surprised that no modifications were made in the /etc/apache2/vhosts.d directory.

    I also ran debug output on the ssl log and didn't see anything that looked like a problem.

    I have done a lot of research on the Internet on this problem and I don't see other people having this problem. I am convinced that I have done something to cause this. I am looking at what could be different on my server and a fresh install of The Perfect Server Opensuse 10.3.

    Here is what I have so far:
    I have installed:
    chkrootkit
    snort
    fail2ban
    KDE
    various development IDEs

    In my network services, these are the additional things that are there now, but were not in a fresh install:
    DHCP server
    DNS server
    DNS and host name
    NIS server
    Routing
    SLP server
    iSCSI target

    Also, I have installed a lot of patches to various things, just whatever was recommended when I checked for updates.
    Most likely, something I have installed, updated or enabled has over written files, changed configurations and/or is not compatible with php, ssl and/or ispconfig.

    What's in Vhosts_ispconfig.conf now? That's the only file that should hold your vhosts, you don't need the vhosts in /etc/apache2/vhosts.d.

    It works!!!
    Thanks for all your help.

    There is now an SSL vhost in Vhosts_ispconfig.conf.

    I got rid of this file: /etc/apache2/vhosts.d/bestamericagifts.conf and it started working.
