Hi all, I am working on Openstack Rocky version. I have two hosts(controller node[10.0.0.11] and compute node[10.0.0.31]). All services (Identity service, Image service, Compute service and Networking service) are working fine and verified too.

But I have a problem with OpenStack-dashboard.

From this link, "https://docs.openstack.org/horizon/rocky/install/install-rdo.html" all installation steps went well and both the services httpd.service and memcached.service are running successfully.

When I come to verify operation and try Access the dashboard using a web browser at http://controller/dashboard the dashboard is not opening. It's giving like this

"This site can’t be reachedcontroller’s server IP address could not be found."

Please help me.

Thanks,

It seems like your name resolution doesn't work. The host where you want to access the dashboard from needs to be able to resolve the controller's hostname.

can you post these two things?

ping from your computer (the one you are using the browser from) to controller by name, not by IP.

ping controller

and also the http logs from the controller node. Basically /var/log/httpd/access.log and /var/log/httpd/error.log

@cbravo If I ping from my computer to controller like., ping controller it's giving like this "Ping request could not find host controller. Please check the name and try again."
