Trying to install lastest OnDemand 1.4 on CentOS 7 virtual server. Following the install instructions and stuck on the “Yum install ondemand”. Getting the following:
–> Finished Dependency Resolution
Error: Package: passenger-5.3.7-1.el6.x86_64 (ondemand-web)
Requires: libpcre.so.0()(64bit)
Error: Package: 100:nginx-1.14.0-1.p5.3.7.el6.x86_64 (ondemand-web)

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

I have installed the missing dependencies but still getting the same error:
yum install pcre.x86_64
yum install ruby-libs.x86_64

Any advice on what I’m missing?

Thank you. Not sure if you made a change already. But I started again with a fresh VM install and was able to successfully install OnDemand. Could be I missed a step on the first try. Moving on to the next section on the install document.

It looks like you installed the CentOS 6 ondemand release RPM and not the CentOS 7 one. Notice how the RPMs getting installed have “el6” in the name, should be “el7”.

Try this:

yum remove ondemand-release-web
yum install https://yum.osc.edu/ondemand/1.4/ondemand-release-web-1.4-1.el7.noarch.rpm

I think I know what I did first time around that failed the install. Under “1. Enable the EPEL and Software Collections repositories:” I only ran the “CentOS 6/7: sudo yum install epel-release centos-release-scl” and skipped the RHEL7 section to install “sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm”. Since I’m installing on CentOS I didn’t think I needed to run something that was tagged only for RHEL 7.
That should probably be changed to “CentOS/RHEL 7” like it is under " 2. Add Open OnDemand’s repository hosted by the Ohio Supercomputer Center:"

I verified this with another fresh install, the install OnDemand fails if you don’t install the RHEL EPEL release.
