Introduction
Puppet is the Configuration Tool for managing with the most expertise at the moment. An application used for setting up, maintaining, and deploying servers. It performs various tasks, including specifying unique settings for every host and routinely checking and verifying that the configuration is there and hasn't been changed (if it has, Puppet will restore the necessary configuration) on the server. Additional features include capacity control and scaling-down of systems, as well as management over all configured machines, enabling automated propagation of changes made centrally (through a master server or repository-based change). With SSL, the Master and Slave of Puppet's Master-Slave architecture may communicate securely and privately.
Installing Puppet Enterprise
Puppet Enterprise (PE), a commercial version of Puppet can manage your IT architecture while being efficient, flexible, and cooperative. You can control heterogeneous architecture throughout its entire life - cycle with the help of PE because it blends a model-driven methodology with the imperative execution of tasks. Version management, code evaluation, test automation, continuous integration, and automatic deployment are just a few of the techniques PE offers as a shared language that almost all teams in an IT organization may utilize to implement successfully.
In addition to the traditional installations using several commands, Puppet Agents must also be installed for PE to run properly to install Puppet Enterprise fully. The installation procedure is split into two phases as a result:
- Installing Puppet Enterprise(PE)
- Installing Puppet Agents
Installation of Puppet Enterprise
Before installing PE, set up standard installation. With the advancement of technology, PE provides flexibility suitable for different installations.
Standard PE installation includes the following 3 components:
- Primary server: The primary hub of action. In addition to compiling Puppet code and signing SSL certificates, it also creates agent catalogs.
- Console: The visual user interface for websites. It offers monitoring and configuration features. It analyses the events, manages user access and compares resources in real-time.
- PuppetDB: The location where data produced by your Puppet architecture is stored.
Install PE tarball. Wondering what tarball is? This is a group of files stored in a single folder and has been compressed and converted to a zip file.
Verification of the installation package
GnuPG (GPG) should be installed on your computer to sign the release key. GPG is used to encrypt and sign digital conversations securely.
To install GPG
yum install gnupg
If you need to verify the authenticity, you can proceed with these steps:
- Install the tarball suitable according to your system architecture.
-
For importing the Puppet public key, run the following command:
uri='https://downloads.puppet.com/puppet-gpg-signing-key-20250406.pub'
curl "$uri" | gpg --import
- To print the key fingerprint, run the following command:
gpg --fingerprint 0x4528B6CD9E61EF26
- Get the GPG SIGNATURE .asc file for your PE tarball by downloading it. On the PE Download page, links to these files can be found.
-
To verify the installation package release signature, run the following command:
gpg --verify puppet-enterprise-<VERSION>-<PLATFORM>.tar.gz.asc
Results
The gpg --verify command produces results that resemble:
gpg: Signature made <DATE_AND_TIME>
gpg: using RSA key <KEY_ID>
gpg: Good signature from "Puppet, Inc. Release Key (Puppet, Inc. Release Key) <release@puppet.com>"You can continue to install PE if you see the message "Good signature."
