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.
- If you are just getting started with Puppet and don’t yet know how to assign Puppet classes to nodes, this is the guide for you.
- If you are already familiar with Puppet and have a working Puppet deployment, we recommend that you use the puppetlabs-puppetdb module instead. See the “Installing PuppetDB via Puppet module” guide for further details.
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.
- After following these instructions, you must connect your Puppet master(s) to PuppetDB. (If you use a standalone Puppet deployment, you will need to connect every node to PuppetDB.)
- These instructions are for platforms with official PuppetDB packages. To install on other systems, follow our instructions for installing from source.
- If this is a production deployment, review the scaling recommendations before installing. You should ensure that your PuppetDB server will be able to comfortably handle your site’s load.
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 master server. If you run
puppet agent --test, it
should successfully complete a run, ending with
Notice: Applied catalog in X.XX
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][keystore_instructions] before the Puppet master will be able to connect to PuppetDB.
Step 2: Enable the Puppet Collection package repository
If you didn’t already use it to install Puppet, you will need to enable the Puppet Collection package repository
Step 3: Install PuppetDB
Use Puppet to install PuppetDB:
$ sudo puppet resource package puppetdb ensure=latest
Step 4: Configure database
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 master servers.
Finish: Connect Puppet 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 (
/var/log/puppetlabs.puppetdb/puppetdb.log), and see whether PuppetDB knows what the problem is.
- If PuppetDB is running but the Puppet master can’t reach it, check
[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/puppetlabs/puppetdb/ssldirectory, 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 master can contact PuppetDB.
