at step 14 perfect Centos 7 server -- I'm getting as some have noticed errors that clamd and unrar are unavailable. missing repository? also continuing sa-update hangs and then fails with cant get to sa-update.secmap.net (network unaccessible) server is online fine of course all the prior yum's were fine!
The only additional repo that is required for the guide is the epel repo. Please check if you enabled that as described in step 7.
epel the perfect server instructions need updating 7.2 no longer exists and gives error. current version seems to be: epel-release-7-5.noarch.rpm I did what one of the commenters suggested: yum install epel-release that did seem to install 7-5.noarch.rpm and this was the result. it did install epel.repo and I did the priority=10 as requested. maybe they are no longer in epel?? and upon examining epel-packages listed at: http://dl.fedoraproject.org/pub/epel/7/x86_64/repoview/letter_c.group.html we see that clamd and (under U group) unrar are NOT listed .... what gives? apparently rpmforge has these two packages - but we dont want to cause other difficulties! ... and repoforge (rpmforge) seems to stop at Centos 6 <sigh>
clam packages are listed as clamav* in the epel repo. I don't see unrar on my centos7 you may have to go searching for that one.
