Learning Puppet 4

Chapter 3. Installing Puppet

In this chapter, you will install the Puppet agent and its dependencies. We have deliberately chosen a Vagrant box that doesn’t have Puppet preinstalled, so that you can go through and learn the process. You can repeat these exact steps on any test or production node to install or upgrade Puppet.

Let’s get started by installing the Puppet Labs package repository.

Adding the Package Repository

Now we’ll install and enable a Puppet Labs Puppet Collection repository on your fresh new system. Our first step is to check what the latest Puppet Collection is. You can find this at “Using Puppet Collections” in the Puppet Labs online documents.

Get the URL for the Enterprise Linux 7 Collection and install that package as described in the documentation.

Tip

For EL/CentOS versions 6 and above, you can simply use yum install rather than rpm -ivh:

[vagrant@client ~]$ sudo yum install -y \
 http://yum.puppetlabs.com/puppetlabs-release-pc1-el-7.noarch.rpm

This installs and enables a Puppet Collection package repository, which contains the Puppet 4 package. After it has finished installing, you can confirm it is enabled with the following command:

[vagrant@client ~]$ sudo yum repolist
