Install puppet

   cd ~ && wget https://apt.puppetlabs.com/puppetlabs-release-pc1-trusty.deb
   sudo dpkg -i puppetlabs-release-pc1-trusty.deb
   sudo apt-get update
   sudo apt-get -y install puppetserver

Configure memory:
sudo vi /etc/default/puppetserver

Start puppetserver
Start Puppet Server Now we're ready to start Puppet Server with this command:
sudo service puppetserver restart
Next, enable Puppet Server so that it starts when your master server boots: sudo /opt/puppetlabs/bin/puppet resource service puppetserver ensure=running enable=true

Install Puppet Agent
Perform these steps on all of your agent servers.
Enable the official Puppet Labs collection repository with these commands:

   cd ~ && wget https://apt.puppetlabs.com/puppetlabs-release-pc1-trusty.deb
   sudo dpkg -i puppetlabs-release-pc1-trusty.deb

Then install the puppet-agent package:

   sudo apt-get update
   sudo apt-get install puppet-agent

Now that the Puppet agent is installed, start it with this command:
sudo /opt/puppetlabs/bin/puppet resource service puppet ensure=running enable=true

The first time you run the Puppet agent, it generates an SSL certificate and sends a signing request to the Puppet master. After the Puppet master signs the agent's certificate, it will be able to communicate with and control the agent node.
