Set node name in puppet to noop option - puppet

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

Disable Puppet agent runinterval

I am using the following Puppet version on CentOS Linux release 7.2:
# puppetserver -v
puppetserver version: 2016.5.0.11
I have a Win agent node and i might have few more later. Agent version on Win node:
C:\Windows\system32>puppet --version
4.8.1
I would like to disable the agent runinterval permanently so i can only push from my Puppet server when required. I saw few links and tried putting the following line in Puppet server's /etc/puppetlabs/puppet/puppet.conf file. I also restarted the server but still the agent is fetching the catalog.
[agent]
daemonize=false
I would also like to know whether it's possible to disable runinterval only on specific nodes. If yes, how?
What you are basically looking at doing is stopping the Puppet service. This is accomplished most easily with a puppet service resource:
service { 'puppet':
ensure => stopped,
enable => false,
}
To do this only on certain nodes, merely supply it for the corresponding node definitions in your classifier or main site manifest:
node /ones_to_disable/ {
service { 'puppet':
ensure => stopped,
enable => false,
}
}
This is the easy and common method for accomplishing push-style Puppet and disabling pull-style.
If you want to disable Puppet agent on given node you have to use this command: puppet agent --disable. You can specify a reason, why you are disabling agent on given node. The message that you could supply will be printed next time someone will type puppet agent on node.

puppet agent --test throwing environment errors

I am trying to keep puppet master and client/agent on one machine. I have been trying this for last 2 days and I am almost close to finishing it.
1) started puppet master "service puppetmaster start". Its successful
2) started puppet agent "service puppet start. Its successful
3) When I try puppet agent --test. see the errors below
This is the error I am getting when I try "puppet agent --test". I tried setting different values for environment in puppet.conf file and also passing from command line args for environment but nothing seems to be working.
Warning: Local environment: "production" doesn't match server
specified environment "none", restarting agent run with environment
"none"
I googled and tried what people said, but no use. It might work if I try agent from one machine and master on the other. But I want to make it work on one machine.
If you want to make it work on one machine you don't use puppet agent -t. you should use puppet apply. here is a reference
https://docs.puppet.com/puppet/latest/re‌​ference/man/‌​apply.html
you can write a small script which will be having puppet apply command with farther argument (of course) and you can name it whatever you want (e.g: Papply) and run it every time whenever you want to run puppet agent -t.
puppet agent -t is not preferred for stand alone Puppet Server & Clint environment.

How to check if puppet is configured correctly?

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.

Agent not reading /etc/sysconfig/puppet server=

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.

Puppet agent can't find server

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.
