Puppet First Steps: How To Install A Puppetmaster With A puppetclient !!TOP!!

The first step was to rip out the puppet foss packages. rpm -qa | grep puppet gives me the list of what to uninstall on the nodes I want to preserve. It may vary based on the role assigned to a node. For instance, on my build node:

Puppet is a centralised server management tool written in Ruby which is available in Ubuntu stable repositories. It has two main components; a central service, the "puppetmaster" daemon and a client "puppet" service, which is installed on every machine that will take instructions from the puppetmaster. It's designed to apply configuration in an idempotent manner. Idempotence in this case means that repeatedly applying rules will always result in the same outcome. This is clearly a necessary requirement of anything that's managing server configuration.

Once you have installed the puppet master set-up you can configure a puppet client for each server you want to manage. Puppet has a neat system where each client is set-up with an SSL certificate so that all communication with the Puppetmaster is carried out securely.

If I need to set-up more hardware for any reason I can order a slice which will be set-up in a matter of minutes. I can then install the puppet client, point it at the puppetmaster and configure it with the set of rules for a webserver and then within a couple of minutes that server will be running all of the necessary software (apache/mod_wsgi/django/python) along with all of our carefully tweaked configuration files.

When setting up the client for install, there are a few caveats which need to be addressed first. The initial concerns will be utilizing a consistent naming scheme across the master and clients. This will allow for an easy way to allow for the addition of more clients down the road. Using server names like puppetclient01.domain.com or pc01.domain.com on the client indicates that this will be the first puppet client server. Using PM01.domain.com for the puppet master server will allow the client to locate and connect with the master easily. This change can be made in the puppet configuration file.

There are two things to check here. The first thing is are you using the correct puppet master name on the client side, and is dns configured properly on both the server and the client(the server should be able to reach the client with the dns name you are using, and vice versa.)

So, you will be able to add multiple agents and manage them easily with Puppet. Send us feedback while using this tool to help your friends use your new experience on Community.

Puppet Server is configured to use 2GB of RAM by default. Just to play around with an installation on a Virtual Machine. However, ram can be reduced to minimum of 512MB in test enviornment. Make sure you have good amount of ram when using puppet server in production though to guarantee optimal performance.

Puppet Server is very straight forward to install and setup. Along with ease, it provides a huge performance improvement over the classic puppet master setup. Now, a single command does all the things (yum install puppetserver) for you. be457b7860
