Puppet agent disabled in Puppet master

Question

In my environment, there is a RHEL puppet master which successfully managing over 500 nodes. When I run puppet in master server (puppet agent -t), I am getting below error. It seems puppet agent is disabled in master. Is there any impact , if I enable puppet agent in master.

*[root@puppet-master]# puppet agent -t

Notice: Skipping run of Puppet configuration client; administratively disabled (Reason: 'reason not specified'); Use 'puppet agent --enable' to re-enable.*

Answer 1

Puppet should be enforcing its own configuration and the default behavior for PE is to run the agent on the master every 30 minutes. You can test to see what would happen if you enabled Puppet using the following steps;

1. run systemctl stop puppet this will just stop the agent service, it won't stop the Puppet server running.
2. Run puppet agent --enable to re-enable Puppet runs.
3. Run puppet agent -t --noop if you run in noop mode it will not apply any changes, just report back what it would change.
4. At this point, if it's not going to make any further changes then you'll be safe to run systemctl enable puppet and start it enforcing itself again. If it is going to make some changes you don't want then run puppet agent --disable to ensure the agent doesn't accidentally restart after a reboot and investigate further.
