    Default OX and Apache2 v2.4

    Hello,

    I'm trying to use apache2 v2.4 for serving the appsuite of ox. The problem is, that apache does not start once I enable proxy_http.conf (for gizzly).

    Has anyone successfully tried to use a2 2.4 in connection with ox or is more familiar wir the configuration of that version of a2?

    My proxy_http.conf is:
    Code:
    # Please note that the servlet path to the soap API has changed:
    <Location /webservices>
        # restrict access to the soap provisioning API

        # you might add more ip addresses / networks here
        # Allow from 192.168 10 172.16
    </Location>
    
    # the old path is kept for compatibility reasons
    <Location /servlet/axis2/services>
        # restrict access to the soap provisioning API
        Require all denied
        Allow from 127.0.0.1

    We are using OX/grizzly with an even older apache 2.2 (Debian 6). What does the apache log / error log say?

    The most notable difference in the proxy_http.conf is that we use "ProxyPreserveHost On". But I do not think, that this should lead to an error state.

    Regards.

    This is what the apache2 error.log says:
    Code:
    [Thu Oct 24 09:45:46.159087 2013] [proxy:crit] [pid 1473] AH02432: Cannot find LB Method: byrequests
    [Thu Oct 24 09:45:46.204362 2013] [proxy_balancer:emerg] [pid 1473] (22)Invalid argument: AH01183: Cannot share balancer
    [Thu Oct 24 09:45:46.204528 2013] [:emerg] [pid 1473] AH00020: Configuration Failed, exiting
    I used "ProxyPreserveHost Off" with apache2 v2.2 successfully as well.

    Hi,

    we've already evaluated Apache 2.4, too. I'll post you our observations so far, but please keep in mind that Apache 2.4 is not yet distributed by the supported platforms. We'll update the official documentation accordingly if this becomes the case.

    Cheers
    Martin

    Code:
    Having apache 2.4 at a supported distro is still a way to go. However, here are some changes we need to take care at documentation when describing ox setup. Tested with Debian Jessie.
    
    * etc/conf.d has moved to etc/conf-available. Configuration files can be en/disabled like:
    a2enconf ox-proxy_http
    a2enconf redirect
    
    * mod_proxy has been refactored, separate lb modules are now available
    a2enmod lbmethod_byrequests
    
    Also, it looks like the mod_proxy syntax has been altered with 2.4
    
    <Proxy /ajax>
      ProxyPass http://localhost:8009/ajax
    </Proxy>
    
    will no longer work, but
    
    <Location /ajax>
      ProxyPass http://localhost:8009/ajax
    </Location>
    
    and 
    
    ProxyPass /ajax http://localhost:8009/ajax
    
    works.

    That's it. I had to activate the mod "lbmethod_byrequests".

    My "proxy_http.conf" now contains:
    Code:
