Puppet is a powerful configuration management and automation tool. Using the client server architecture of puppet, one can manage hundreds or even thousands of servers. Puppet saves lot of time for the system administrator. In this article I am going to give detailed steps to install and configure puppet Client/Server model in CentOS machines. Here I am using two VMs called puppet-server and puppet-client to demonstrate the puppet Client/Server setup.
Installation
Puppet package is provided in EPEL repository. We need to enable it to install puppet using YUM. On both puppet-server and puppet-client, install EPEL repository.
Note : I am using CentOS 5.7, so I am going to install EPEL for CentOS 5.
rpm -ivh epel-release-5-4.noarch.rpm
Add the hostname of client and server in the /etc/hosts file of both puppet-server and puppet-client, if the hostname is not resolvable over DNS
172.16.137.176 puppet-client.test.net puppet-client
Installation of puppet server
/etc/init.d/puppetmaster start
iptables -I INPUT -p tcp –dport 8140 -j ACCEPT
The puppet server listens on port 8140. That port should be open in firewall, if the firewall is enabled in the server.
Installation of puppet-client
Testing the installation
On puppet-client
That will create the cert. Go to the puppet-server and see, if the cert request is there from the client.
if its there, then sign the cert
After signing the certificate. Try the client again.
You should be able to connect. If the connection works, then start the puppet client.
