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

@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

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

 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...

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

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.
