How to add ondemand-web repo and install httpd24-mod_auth_openidc

Hi,

Our team is trying to implement OOD at the University of Nebraska Lincoln. I am following the documentation to set up Keycloak and stuck at the yum install httpd24-mod_auth_openidc step. Can someone please explain how to install httpd24-mod_auth_openidc from ondemand-web repo?

Thanks,
Jingchao

What was the command you used to add the ondemand-web repo? Once the repo RPM is installed you should be able to install httpd24-mod_auth_openidc as you described. I’d double check you installed the correct repo file, for example if your on CentOS 7 make sure you installed the EL7 repo RPM or this one which isn’t documented yet: https://yum.osc.edu/ondemand/1.6/ondemand-release-web-1.6-1.noarch.rpm

Thanks for the reply. Yes, we do have the ondemand-web repo installed, and I also tried the repo you mentioned above. Please check the outputs below:

I haven’t done that myself, our admin Steve did, but, he wrote down what he did and we have that at https://github.com/CHPC-UofU/OnDemand-info#keycloak. Perhaps you find that helpful.

From what I can tell the httpd24-mod_auth_openidc is coming from the base CentOS repo, not from OOD. Our server has that installed and I don’t recall Steve saying that was a problem.

We do run the Keycloak on a separate server (to which I can’t ssh :wink: ).

Thanks Martin. It is a package from the ondemand-web repo but our puppet wiped out the repo files. An uninstall and clean install fixed the issue.
