Installation puppet server and client in centos 6.7

Installation server and client  in Centos 6.7

 Puppet server listening on 8140 on the Puppet Master

 rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm

puppet master service install

yum install puppet-server

command to upgrade Puppet to most newest version

puppet resource package puppet-server ensure=latest

 /etc/init.d/puppetmaster restart

On the Master clean the old client certificate:
puppet cert clean <certname>

The server has received the client's CSR which has to be manually signed:

 puppet cert sign <certname>

On the Master we can use puppet cert to manage certificates

List the (client) certificates to sign:
puppet cert list

List all certificates: signed (+), revoked (-), to sign ( ):
puppet cert list –all

Sign a client certificate:
puppet cert sign <certname>

Remove a client certificate:

puppet cert clean <certname>

Client stores its certificates and the server's public one in $vardir/ssl** (/var/lib/puppet/ssl on

Puppet OpenSource)

Server stores clients public certificates and in $vardir/ssl/ca (/var/lib/puppet/ssl/ca).

DO NOT remove this directory.

puppet agent install

yum install puppet

upgrade the installed puppet agent

 puppet resource package puppet ensure=latest

restart the puppet service
/etc/init.d/puppet restart

puppet agent --test

Run puppet agent in foreground and debug mode:
puppet agent --test –debug

Run a dry-run puppet without making any change to the system:
puppet agent --test –noop

 certificate approval (by default 120 seconds) in the first Puppet
puppet agent --test --waitforcert 120

puppet config print all

puppet config print all
puppet config print modulepath

Clean up the client certificate. On the client remove it:
mv /var/lib/puppet/ssl /var/lib/puppet/ssl.old

Puppet some importance path

/var/log/puppet contains logs (but also on normal
syslog files, with facility daemon), both for agents and
master

/var/lib/puppet contains Puppet operational data
(catalog, certs, backup of files…)

/var/lib/puppet/ssl contains SSL certificate

/var/lib/puppet/clientbucket contains backup copies
of the files changed by Puppet

/etc/puppet/manifests/site.pp (On Master) The first
manifest that the master parses when a client connects
in order to produce the configuration to apply to it
(Default on Puppet < 3.6 where are used config-file
environments)

/etc/puppet/environments/production/manifests/site.pp
(On Master) The first manifest that the master parses
when using directory environments (recommended
from Puppet 3.6 and default on Puppt >= 4)
/etc/puppet/modules and

/usr/share/puppet/modules (On Master) The default
directories where modules are searched

/etc/puppet/environments/production/modules (On
Master) An extra place where modules are looked for
when using directory environments
