Puppet – How to install and configure Puppet Enterprise (Master) ?

This article is going to brief about the Puppet Server – Enterprise installation and configuration. We are going to install the puppet server  in monolithic mode. In monolithic installation, Puppet Master , Puppet console , Puppet DB will be installing on one node. This is the simple method to evaluate puppet enterprise and you can manage up to 500 puppet agent nodes. To know more about Monolithic installation vs Split installation , please refer this article.

• Working DNS  Set-up or /etc/hosts

Puppet Enterprise documentation can be found at http://docs.puppetlabs.com/pe/2015.3/

STEP 1: GUIDED INSTALLATION

Before you begin, choose an installation method. We've provided a few paths to choose from.

- Perform a guided installation using the web-based interface. Think of this as an installation interview in which we ask you exactly how you want to install PE.
In order to use the web-based installer, you must be able to access this machine on port 3000 and provide the SSH credentials of a user with root access. This
method will login to servers on your behalf, install Puppet Enterprise and get you up and running fairly quickly.

- Use the web-based interface to create an answer file so that you can log in to the servers yourself and perform the installation locally. If you choose not to
use the web-based interface, you can write your own answer file, or use the answer file(s) provided in the PE installation tarball. Refer to Answer File
Installation (http://docs.puppetlabs.com/pe/2015.3/install_automated.html), which provides an overview on installing PE with an answer file.
