Automation-with-puppet

This is a basic workshop for beginners to learn puppet5.

Inside the set-up folder, you will find the server and the client files. Both these files contain the Vagrant file. You need to vagrant up in both the folders(server and client).

Note: Vagrant must be installed with libvirt as provider to perform this workshop.

Once vagrant up command is complete run vagrant ssh. You are now inside the centos machine that you just created!

Become root by su command(password=vagrant) and follow the commands given bellow.

Make sure time on both the machines are synced. (Run this on both client & server machines)

	# yum -y install ntpdate
	# yum 0.centos.pool.ntp.org
	#timedatectl set-timezone Asia/Kolkata

Create Flat dns. (Run this on both client & server machines)

	# ifconfig
	# put the ip address in /etc/hosts with the name `puppet-master puppet-master.exmaple.com`
	  for server and `puppet-agent` for client
	  
	Note : If ifconfig command does nto exist, then install `net-tools` package.
	

Installation Steps. (run this on both client and server machines)

	# rpm -Uvh http://yum.puppetlabs.com/puppet5/puppet5-release-el-7.noarch.rpm
	you can check for the file puppetlabs.repo in /etc/yum.repos.d/

Server:

	# yum install -y puppetserver
	
	# vi /etc/sysconfig/puppetserver
		
		change the memory values to `1g`
		JAVA_ARGS = "-Xms1g -Xmx1g ....."
	
	# vi /etc/puppetlabs/puppet/puppet.conf (add these lines at the end of the file)
			
		dnf_alt_names = puppet-master, puppet-master.example.com
		certname = puppetcert1
	
	# systemctl start puppetserver.service

	# systemctl enable puppetserver.service

Client:

	# yum install -y puppet

	# vi /etc/puppetlabs/puppet/puppet.conf
	
		server = puppet-master.example.com
	
	# /opt/puppetlabs/bin/puppet resource service puppet ensure=running

Server:

	# /opt/puppetlabs/bin/puppet cert list

	# /opt/puppetlabs/bin/puppet cert sign <client-name-mentioned-in-cert>
	

Client:

	# /opt/puppetlabs/bin/puppet agent -t

happy hacking :)
