rhq and mod_proxy

miniskipper miniskipper Newbie

I can't get rhq and apache's mod_proxy work together. When setting a ProxyPass like this:


ProxyPass /rhq  http://<otherserver>:7080

ProxyPassReverse /rhq  http://<otherserver>:7080


and then try opening the site https://<domain>/rhq i get the following error:


The requested URL /installer/welcome.jsf was not found on this server.




Any advice?

    That's not supported, due to the fact that there are numerous places in the RHQ GUI code base that assume that the GUI is deployed to the root context.

    Thanks for the clarification about the Proxy.


      ProxyPass /  http://<otherserver>:7080

      ProxyPassReverse /  http://<otherserver>:7080

    works, except on strange issue:


    When trying to log in, i get the error "Database not available".

    When i then press F5 i instantly get to the dashboard and all works  o0

    Are there any error messages in the RHQ Server log, during the time when the "Database not available" error occurred in the GUI?

    No error in the log. When connecting from local network it works as expected. Since connections from "outside" are rare, this is no big deal. Thanks for your help regarding mod_proxy.

    I encountered the "Database not available" message after attempting to proxy RHQ using mod_proxy...

    I managed to get it to work as expected though using the following configuration.


    <Proxy balancer://jon>




    # Used by JON

    Header edit Location ^ https://myserver.example.com/jon


    ProxyPass /jon balancer://jon

    ProxyPassReverse /jon balancer://jon


    ProxyPass /installer balancer://jon/installer

    ProxyPassReverse /installer balancer://jon/installer

    ProxyPass /resource balancer://jon/resource

    ProxyPassReverse /resource balancer://jon/resource

    ProxyPass /a4j balancer://jon/a4j

    ProxyPassReverse /a4j balancer://jon/a4j

    ProxyPass /css balancer://jon/css

    ProxyPassReverse /css balancer://jon/css

    ProxyPass /js balancer://jon/js

    ProxyPassReverse /js balancer://jon/js

    ProxyPass /images balancer://jon/images

    ProxyPassReverse /images balancer://jon/images

    ProxyPass /rhq balancer://jon/rhq

    ProxyPassReverse /rhq balancer://jon/rhq

    ProxyPass /coregui balancer://jon/coregui

    ProxyPassReverse /coregui balancer://jon/coregui

    ProxyPass /sessionAccess balancer://jon/sessionAccess

    ProxyPassReverse /sessionAccess balancer://jon/sessionAccess

    ProxyPass /j_security_check.do balancer://jon/j_security_check.do

    ProxyPassReverse /j_security_check.do balancer://jon/j_security_check.do



    At that point, I may as well setup a virtual host and pass / instead.


    BTW, I was able to proxy behind a Location directive using mod_filter, mod_substitute, mod_rewrite and redirects, but the POST attempts would fail unless I used 307 redirect instead of 301. The 307 redirect caused the browser to prompt for confirmation on the redirect, as expected. Even with all that, which was kinda fun to figure out, there appears to be a fair bit of client side that is hard-coded. Yeah, yeah, I know you said that. So I said, meh for now.


    I am not attempting to rewrite/rebase the /coregui and related URL behind a single webapp such as /rhq/coregui or /jon/coregui for the reason that is listed earlier in the thread.  I am proxying behind https.
