How to RPM Install JBoss EAP 7 on RHEL 7

We will start fresh with a unregistered RHEL 7, so we first register the machine and their enter our username and password.

subscription-manager register
...

After that we are ready to add EAP7 subscription. You can here use the auto attach feature, but I recommend using a more controlled way, by adding specific pools.

subscription-manager list --available | less
...
Subscription Name:   JBoss Business Partner Self-Supported NFR
Provides:            Red Hat OpenShift Enterprise JBoss EAP add-on Beta
                     Red Hat JBoss A-MQ Clients
                     Red Hat Single Sign-On
                     Red Hat OpenShift Enterprise JBoss EAP add-on
                     JBoss Enterprise Application Platform
                     Red Hat JBoss Core Services
                     Red Hat JBoss Data Grid
                     JBoss Enterprise Web Server
                     Red Hat JBoss A-MQ Interconnect
...
Pool ID:             XXXXXXXXXXXXXXXXXXXXXXXXX
...

subscription-manager attach --poolid=XXXXXXXXXXXXXXXXXXXXXXXXX

Now you think we are done, and check active RPM repos, but do not see any EAP repo. Why? Because the are two EAP 7 repos for RHEL7. A Current (always upgrade, i.e. 7.1, 7.2, etc) and a Minor (freeze to specific minor version, e.g. 7.0). I recommend using the Current.

When EAP repo in place, please go ahead and install, with groupinstall.

yum grouplist hidden | grep -i eap
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
   JBoss EAP 7

yum groupinstall "JBoss EAP 7"

And then test it.

systemctl restart eap7-standalone

systemctl status eap7-standalone
