I am trying to install on my AWS Red Hat 7 EC2. After I rum “yum clean all” and then “yum install kaltura-server”, this is the error I get at the end of the installation.
After you install these, you can disable the CentOS-Base.repo so no additional packages are fetched from it or you can set priorities so that only packages that do not exist in your official RHEL 7 repos are taken from it.
For that, see: https://wiki.centos.org/PackageManagement/Yum/Priorities
Replace $releasever with a hardcoded 7, like so:
mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os&infra=$infra
RHEL and CentOS are completely compatible and essentially have exactly the same versions for all packages [only CentOS has a few RHEL does not] but because you’re on RHEL $relasever is set to “7Server” thus resulting in a 404 since the CentOS repos call the version simply “7”.
you can easily see that by going here: http://mirror.centos.org/centos/
The dir is “7” as in http://mirror.centos.org/centos/7 and not http://mirror.centos.org/centos/7Server
