For a start, you should use "centos7", not "centos". "juju add-machine
--series=centos" *should* give you an immediate error indicating that
that's not a valid series, and ideally inform you of the closest match(es);
I'll file a bug to get that fixed.

Do you need to build from source? If you're using a released version of
Juju, then the agents are available on streams.canonical.com.

For dev builds, we don't have a nice, supported solution. The supported
solution is to create agent tarballs and generate simplestreams metadata. I
wrote a plugin a while ago that you can use to build and upload agent
tarballs to the controller directly, but you shouldn't use it in production
systems:

$ go get github.com/axw/juju-tools
$ juju tools build 2.2-beta4.1-centos7-amd64
building: juju-2.2-beta4.1-centos7-amd64.tgz
$ juju tools upload -m controller juju-2.2-beta4.1-centos7-amd64.tgz
uploading "juju-2.2-beta4.1-centos7-amd64.tgz"
$ juju add-machine --series=centos7

Cheers,
Andrew
