Pacemaker missing?

Hi All,

Im trying to setup a cluster for the first time so i can get a grip of it but from what i have been reading you need something called "pacemaker" which i cant seem to find via Yum which is instructed by official red hat documentation.
Link:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html-single/High_Availability_Add-On_Administration/index.html#s1-clusterinstall-HAAA

I have however found source for this program but would like to make sure im not missing or doing something wrong?

Any help would be fantastic?

Thanks
