I got stacked with this for some days.
I followed the instructions in there, but I got dependency errors.

Dependency resolving failed due to missing dependencies.
Some repositories on your system are disabled, but yum can enable them
and search for missing dependencies. This will require downloading
metadata for disabled repositories and may take some time and traffic.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
I checked "IVYKIS_0.40", but this is not provided for RHEL7.
so I changed it to "czanik-syslog-ng333-epel-7.repo".
It worked for me.
