We have several servers working with puppet as agents today, but I'm having a problem with a new server running CentOS 7. Normally I would update the /etc/sysconfig/puppet file with the puppet master name and then start the daemon and move to signing the certificate on the master. However, puppet agent doesn't appear to be reading the server = myhost.domain in my config file.
I get the following error in /var/log/messages:
puppet-agent[11133]: Could not request certificate: getaddrinfo: Name or service not known
I tried:
myserver:root$ puppet agent --configprint server
puppet
myserver:root$
but the /etc/sysconfig/puppet file has:
PUPPET_SERVER=myserver.domain.com
Can you please help me understand why puppet agent doesn't get the server from the config file?
The /etc/sysconfig/puppet file is not typically read by the Puppet agent. (I'm not very familiar with CentOS operations, but I suppose that this location might hold some settings that are external to the process, such as environment, command line switches etc.)
You will want to use the proper puppet configuration file:
/etc/puppet/puppet.conf for Puppet 3.x and earlier
/etc/puppetlabs/puppet.conf for Puppet 4.x
so ran the following:
"puppet agent --no-daemonize --verbose --onetime --server puppetmaster.xxx.com"
this started puppet properly, requested certificate and I was able to sign on master. Then added:
server = puppetmaster.xxx.com
to /etc/puppet/puppet.conf and "systemctl restart puppet"
and it worked. Thanks for posts here and other places.

I have created the puppet master using aws opsworks. and I am able to add ami linux nodes automatically to the puppet master.
I am having issues when I tried to to add a windows 64 bit node to my puppet master by following this link https://puppet.com/docs/pe/2017.3/installing/installing_agents.html#install-windows-agents-with-the-msi-package
I copied the puppet-agent-x64.msi from the puppet master present in location to the windows node and /opt/puppetlabs/server/data/packages/public//windows-x86_64-/ and ran the installer to install the agent. the installation is successful and the Start Menu contains a Puppet folder with shortcuts for running the agent manually, running Facter, and opening a command prompt for use with Puppet tools.
But the windows node is not showing in puppet web ui and when i tried to run the puppet agent i get this error
"Running Puppet agent on demand ...
Error: Could not request certificate: Error 403 on SERVER: Forbidden request: /puppet-ca/v1/certificate/ca (method :get). Please see the server logs for details.
Exiting; failed to retrieve certificate and waitforcert is disabled
Press any key to continue . . ."
You'll need to set allow_unauthenticated_ca to true on your OpsWorks master and then run puppet on it to make the change. Afterwards, you should be able to install the agent even if you're not provisioning from AWS or choose not to use the userdata script.
Steps:
login to console.
click on classification
under PE infrastructure, select PE master.
Go to configuration tab
look for class puppet_enterprise::profile::master
under parameters, select allow_unauthenticated_ca and set it to true

I am trying to set up Puppet for DevOps. I have puppet server in Ubuntu 14.04 and puppet-agent in Windows 10. When I am generating certificate for the first time from puppet-agent (Windows 10) the SSL certficate is generating without any issues and even I can sign the same certificate from puppetserver (Ubuntu 14.04), however after signing when I am trying to update the status in puppet-agent (Windows 10) by "puppet agent -t" getting error as,
Error: Could not request certificate: SSL_connect returned=1 errno=0 state=error: certificate verify failed: [unable to get local issuer certificate for /CN=username-virtualbox.domain.com]
The puppet configuration file details:
puppet.config (puppetserver [Ubuntu]):
Troubleshooting steps already tried,
Time zone in both the environments are in sync
Deleted "ssl" folders containing the details of the ssl certificates from both the environments several times and re-tried
8140 ports are enabled on both Windows and Ubuntu
I faced the same problem,
Try to run cmd as admin
I am having the same issue -- been working it for a few weeks now. I cannot guarantee yet that mine is working correctly all the time. Here are some steps I have taken. I hope they are helpful to others.
I am running Puppet Enterprise 2018.1.4. Puppet Agent 5.5.6 on RHEL 7.4.
1) The SSL routine uses a time stamp. Ensure the time is the same between Master & Client.
2) clean/remove the agent cert from the Master AND the Client. On my RHEL, the Client cert is is in /etc/puppetlabs/puppet/ssl/* -- remove any files with the agent name in here.
3) Make sure your puppet enabled on your agent: puppet agent --enable
4) If a client does not contact the puppet master "for a while" the master will drop the client from it's node list, but NOT remove the cert. In theory, the master SHOULD return the node to an active status.
5) Can you run the puppet agent on the master & get the expected results? If not -> problem with puppet code, otherwise, problem with agent.
6) Is puppet.conf configured correctly? Under the [main] section, do you have the server entry correct? Under [agent] are you set to the correct environment? Is noop set to true?
7) It is possible that you have an error in a puppet module that is causeing the agent to exit quietly. Run puppet parser validate on all of your .pp files
8) Can the master resolve the IP address of the master and the client? Can the client resolve the the IP address of the master and the client? Is resolv.conf set correctly on both hosts?
9) hostnames of the client & master should be correct. Each server should know it's shortname, FQDN and IP. On RHEL, I run: hostname; hostname -f; and hostname -i, respectively.
10) File permissions on all the directories & modules should be correct. Check out a working module, see it's owner, group & permissions. Ensure your module is the same.
11) Only root/admin can correctly run puppet agent.
12) On RHEL, the logs are under /var/log/puppet. Do you see any errors there?
13) run puppet agent with the --debug or the --trace option in addition to -t. Pipe this output to a file and see if you can spot any errors.
14) Can you force the master to run the puppet agent on the client successfully?
Many of these things have been narrowing down my issue. I don't know yet if it is fixed, as It takes a while for a node to drop out. Hopefully these will fix your issue.
Hope it helps. There are LOTS of things that could be going wrong.
How can I check if my puppet set-up (one master, one agent on Ubuntu 14.04 ) is configured correctly? Is there some command to verify if everything is right?
If you want to know, whether the puppet agent can connect to the puppet master and pull the configs. You can try running the agent in dry-run mode:
puppet agent -t --noop
For more details: https://docs.puppet.com/puppet/latest/reference/man/agent.html
Note: You may need to sign the puppet agent cert on the master, if you don't have auto signing enabled.
I'm new to puppet, but picking it up quickly. Today, I'm running into an issue when trying to run the following:
$ puppet agent --no-daemonize --verbose --onetime
**err: Could not request certificate: getaddrinfo: Name or service not known
Exiting; failed to retrieve certificate and waitforcert is disabled**
It would appear the agent doesn't know what server to connect to. I could just specify --server on the command line, but that will be of no use to me when this runs as a daemon in production, so instead, I specify the server name in /etc/puppet/puppet.conf like so:
[main]
server = puppet.<my domain>
I do have a DNS entry for puppet.<my domain> and if I dig puppet.<my domain>, I see that the name resolves correctly.
All puppet documentation I have read states that the agent tries to connect to a puppet master at puppet by default and your options are host file trickery or do the right thing, create a CNAME in DNS, and edit the puppet.conf accordingly, which I have done.
So what am I missing? Any help is greatly appreciated!
D'oh! Need to sudo to do this! Then everything works.
I had to use the --server flag:
sudo puppet agent --server=puppet.example.org
I actually had the same error but I was using the two learning puppet vm and trying run the 'puppet agent --test' command.
I solved the problem by opening the file /etc/hosts on both the master and the agent vm and the line
***.***.***.*** learn.localdomain learn puppet.localdomain puppet
The ip address (the asterisks) was originally some random number. I had to change this number on both vm so that it was the ip address of the master node.
So I guess for experienced users my advice is to check the /etc/hosts file to make sure that the ip addresses in here for the master and agent not only match but are the same as the ip address of the master.
for other noobs like me my advice is to read the documentation more clearly. This was a step in the 'setting up an agent vm' process the I totally missed xD
In my case I was getting same error but it was due to the cert which should been signed to node on puppetmaster server.
to check pending certs run following:
puppet cert list
"node.domain.com" (SHA256) 8D:E5:8A:2*******"
sign the cert to node:
puppet cert sign node.domain.com
Had the same issue today on puppet 2.6 on CentOS 6.4
All I did to resolve the issue was to check the usual stuff such as hosts and resolv.conf to ensure they were as expected (compared with a working server) and then;
Removed /var/lib/puppet directory rm -rf /var/lib/puppet
Cleared the certificate on the puppet master puppetca --clean
servername
Restarted the network service network restart
Re-ran puppet
Even though the resolv.conf was identical to the working server, puppet updated resolv.conf and immediately re-signed the certificate and replaced all the puppet lib files.
Everything was fine after that.
I'm using puppet and want to test it with noop, but some configuration depends on the hostname like the node types.
How can I set the node name and run puppet with noop to check the node configuration that match the node name?, currently i got this as error message (my laptop is solaria):
Could not find default node or by name with 'solaria, solaria.lan' on node solaria.lan
Thanks.
puppetd --test --noop --fqdn="hostname.example.com"
Or with 2.6, this may be preferable:
puppet agent --test --noop--fqdn="hostname.example.com"
This will tend to create new certificates on the puppet master, so you'll probably need to run puppetca --clean hostname.example.com on the puppet master afterwords, otherwise when you finally get hosts with those names they'll be unable to set up an SSL relationship with the master.
I just figure out one possible solution, adding this to my config file
nodename = cert
certname = hostname
