Note: If you are running Puppet Enterprise 3.0 or later, PuppetDB is already installed as part of PE. You do not need to install it separately.

This page describes how to manually install and configure PuppetDB from the official packages.

Additionally, these instructions may be useful for understanding the various moving parts, or in cases where you must create your own PuppetDB module.


Step 1: Install and Configure Puppet

If Puppet isn’t fully installed and configured yet on your PuppetDB server, install it and request/sign/retrieve a certificate for the node.

Your PuppetDB server should be running puppet agent and have a signed certificate from your puppet master server. If you run puppet agent --test, it should successfully complete a run, ending with “notice: Finished catalog run in X.XX seconds.”

Note: If Puppet doesn’t have a valid certificate when PuppetDB is installed, you will have to run the SSL config script and edit the config file, or manually configure PuppetDB’s SSL credentials before the puppet master will be able to connect to PuppetDB.

Step 2: Enable the Puppet Labs Package Repository

If you didn’t already use it to install Puppet, you will need to enable the Puppet Labs package repository for your system.

Step 3: Install PuppetDB

Use Puppet to install PuppetDB:

$ sudo puppet resource package puppetdb ensure=latest

Step 4: Configure Database

If this is a production deployment, you should confirm and configure your database settings:

You can change PuppetDB’s database at any time, but note that changing the database does not migrate PuppetDB’s data, so the new database will be empty. However, as this data is automatically generated many times a day, PuppetDB should recover in a relatively short period of time.

Step 5: Start the PuppetDB Service

Use Puppet to start the PuppetDB service and enable it on startup.

$ sudo puppet resource service puppetdb ensure=running enable=true

You must also configure your PuppetDB server’s firewall to accept incoming connections on port 8081.

PuppetDB is now fully functional and ready to receive catalogs and facts from any number of puppet master servers.

Finish: Connect Puppet to PuppetDB

You should now configure your puppet master(s) to connect to PuppetDB.

If you use a standalone Puppet site, you should configure every node to connect to PuppetDB.

Troubleshooting Installation Problems

  • Check the log file, and see whether PuppetDB knows what the problem is. This file will be either /var/log/puppetdb/puppetdb.log.
  • If PuppetDB is running but the puppet master can’t reach it, check PuppetDB’s jetty configuration to see which port(s) it is listening on, then attempt to reach it by telnet (telnet <host> <port>) from the puppet master server. If you can’t connect, the firewall may be blocking connections. If you can, Puppet may be attempting to use the wrong port, or PuppetDB’s keystore may be misconfigured (see below).
  • Check whether any other service is using PuppetDB’s port and interfering with traffic.
  • Check PuppetDB’s jetty configuration and the /etc/puppetdb/ssl directory, and make sure it has a truststore and keystore configured. If it didn’t create these during installation, you will need to run the SSL config script and edit the config file or manually configure a truststore and keystore before a puppet master can contact PuppetDB.
