AEM dispatcher issue

[Former Community Member]

I have configured CQ dispatcher on CentOs machine and tested the "dispatcher flush agent" it is showing test succeeded message. but when I am trying to access a geometrix page from my server ( 55.55.55.5 or localhost:80/content/geometrixx/en/products.html ) the server is displaying this error message "the proxy server received an invalid response from upstream server"

I am pasting the dipatcher log trace here and also attaching required files for reference. Please help me in resolving this

Please check this section "CONFIGURE SELINUX PROPERTIES" here:

http://docs.adobe.com/docs/en/dispatcher/disp-install.html

@Feike

I have ignored the step...so please help me in this...

Enter the following commands in a terminal window, replacing [path to the dispatcher.so file] with the path to the Dispatcher module that you installed to Apache Web Server, and [path to the docroot] with the path where the docroot is located (e.g. /opt/cq/cache):

semanage fcontext -a -t httpd_modules_t [path to the dispatcher.so file]

setsebool -P httpd_can_network_connect on

chcon -R --type httpd_sys_content_t [path to the docroot]

semanage fcontext -a -t httpd_sys_content_t "[path to the docroot](/.*)?"

so what should be the doctoot here...? in dispatcher,any file docroot defined as \opt\communique\dispatcher\cache  and my apache doc root is /var/www/html

[Jörg_Hoh]

You should set the dispatche docroot and the apache webserver docroot to the same directory.

@Jorg

 please help me in resolving this in Configure SELinux Properties for dispatcher

semanage fcontext -a -t httpd_modules_t [path to the dispatcher.so file ]

setsebool -P httpd_can_network_connect on

chcon -R -- type httpd_sys_content_t /var/www/html

It is saying command "chcon" not found...The first two commands excuted successfully after installing semanage package...

[Jörg_Hoh]

Have you executed this as root user? chcon should be part of the coreutils RPM package.

regards,
Jörg

@Jorg

No...Thanks for this input... Actually I am trying to configure this on Vagrant managed centOs virtual machine with puppet provisioning.. I will modify current user as root in dipatcher puppet script...Thanks again for ur valuble input..I will get back with an update..

@Jorg

I have  configured SElinux properties and then tested the caching functionality...The server is responding with 404 resource not found.. I am adding my dispatcher logs below for your reference.
