Initial install and setup of cfengine on a New World host

The full cfengine documentation is on the cfengine web site.

Install cfengine for AWS clients

After Debian has been installed on a host (e.g., Initial setup of a Debian AMI instance) perform the following steps on the host:

• Install the cfengine3 package:

# apt-get -y install cfengine3
# systemctl mask cf-monitord
# systemctl mask cf-serverd
# cd /var/lib/cfengine3
# mv inputs inputs.original
# mv masterfiles masterfiles.original
# rm -fr inputs masterfiles
# mkdir inputs masterfiles

• Enable cf-execd in /etc/default/cfengine3
• Set the host name (used by cf-agent)
• Run: cf-agent -B <cfengine hub address> -v
• Observe last line of output showing, hopefully, promises kept and repaired totalling 100% and promises not kept at 0%
• cf-execd should now be running
• Run cf-agent -K -v a few times until it stops repairing things, or just wWait and let cf-execd run cf-agent in the background. In the latter case kKeep an eye on /var/log/cfengine3/promise_summary.log

Rebooting is generally not required as the cf-agent will appropriately restart or reload any daemons or instantiate any other settings as it makes changes.
