Installing Puppet: From Gems

Included in Puppet Enterprise 3.8. A newer version is available; see the version menu above for details.

Note: This document covers open source releases of Puppet version 3.8 and lower. For current versions, you should see instructions for installing the latest version of Puppet or installing Puppet Enterprise.

On *nix platforms without native packages, you can install Puppet with Ruby’s gem package manager. This isn’t recommended unless there are no native packages for your OS.

First

Before installing Puppet, review the pre-install tasks.

Step 1: Ensure Prerequisites are Installed

Use your OS’s package tools to install both Ruby and RubyGems. You might need to compile and install these yourself.

On Linux platforms, ensure that the LSB tools are installed. We recommend installing at least lsb_release. See your OS’s documentation for details about its LSB tools.

Step 2: Install Puppet

To install Puppet and its dependencies, run:

sudo gem install puppet

Upgrading

Note: Read our tips on upgrading before upgrading your Puppet deployment.

To upgrade to the latest version of Puppet, you can run:

sudo puppet resource package puppet ensure=latest provider=gem

After upgrading, restart the puppet service and, if applicable, the Puppet master web server.

Step 3: Pre-Configure Puppet

RubyGems lacks some of the conveniences that native packages have. To prepare for the post-install tasks, do the following:

Create Users

The Puppet master service needs a puppet user and group. If this node might ever act as a Puppet master server, do the following now:

  1. Create a puppet group:

    sudo puppet resource group puppet ensure=present
    
  2. Create a puppet user:

    sudo puppet resource user puppet ensure=present gid=puppet shell='/sbin/nologin'
    

Create an Init Script for Puppet Agent

To run Puppet agent as a service, you need an init script (or whatever your OS’s equivalent is).

Because each platform handles init scripts differently, you must find one specific to your operating system or build one yourself based on what you know about your chosen operating system. The ext directory in the Puppet source includes several example init scripts or service configurations for various operating systems:

Do not start the puppet or Puppet master services yet.

Create a Confdir and Config Files

When you install with gems, your confdir might be empty or missing. Populate it with these required files:

  1. Make sure the confdir exists. This directory is usually at /etc/puppet/.
  2. Create a puppet.conf file in the confdir. You can leave it empty until the post-install tasks.
  3. If this node will ever act as a Puppet master, it needs an auth.conf file. Use the default auth.conf file from the Puppet source, and put it in the confdir.
  4. Create a main manifest and a module directory. Alternately, enable directory environments in puppet.conf and create a production environment, as described in the directory environments page.

Make Sure Puppet Can be Loaded

Run puppet --version. This should output the version of Puppet you now have installed.

Next

At this point, Puppet is installed, but it isn’t configured or running. You should now do the post-install tasks.
