Latest update: I rebuilt the centos 7 server. I then did a: yum update
Different error. As before, everything worked through the service webconfig stop. I was able to do the yum install for app-accounts successfully. When I tried to do the yum install for app-configuration-backup I had it fail with an error:

It seems that doing the yum update after initially bringing up the centos server changed things. Does clearcenter need to update its repos for a different version of bind?

Here is the entire yum install command and output:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
