Installing from packages

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

This page describes how to manually install and configure PuppetDB from the official packages. Users are encouraged to install PuppetDB via the PuppetDB module instead of installing the packages directly. Using the module for setting up PuppetDB is much easier and less error prone. See Installing PuppetDB via Puppet module for more info.

Additionally, these instructions may be useful for understanding PuppetDB's various moving parts, and can be helpful if you need to create your own PuppetDB module.

Notes:

Platform specific install notes

Ubuntu 18.04

  • Enable the universe repository, which contains packages necessary for PuppetDB

  • Ensure Java 8 is installed

Step 1: Install and configure Puppet

If Puppet isn't fully installed and configured 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 Server. If you run puppet agent --test, it should successfully complete a run, ending with Notice: Applied catalog 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 Server will be able to connect to PuppetDB.

Step 3: Install PuppetDB

Use Puppet to install PuppetDB:

$ sudo puppet resource package puppetdb ensure=latest

Step 4: Configure database

  • [Set up a PostgreSQL server and configure PuppetDB to use

  • it]configure_postgres. If your PostgreSQL node is on a separate server than PuppetDB, you should configure an SSL connection, otherwise your database communication will happen in plaintext over the network. This can be made much simpler by installing using the PuppetDB module.

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 facts, catalogs, and reports from any number of Puppet Servers.

Troubleshooting installation problems

  • Check the log file (/var/log/puppetlabs.puppetdb/puppetdb.log), and see whether PuppetDB knows what the problem is.

  • If PuppetDB is running but the Puppet Server 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 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/puppetlabs/puppetdb/ssl directory, and make sure it has the necesary SSL files created. If it didn't create these during installation, you will need to run the SSL config script and edit the config file before a Puppet Server can contact PuppetDB.
