How to Fix a PuppetDB SSL Error

If you don’t know what PuppetDB is, this post probably will not be useful to you. But if you want to learn about it, you can visit the official documentation: http://docs.puppetlabs.com/puppetdb/latest/index.html.

For PuppetDB to work, it needs SSL certificates generated by a Puppet master. In my case, I needed to reconfigure an existing PuppetDB instance to use a new Puppet master that was running on the same server. Here’s how I did it:

Stop the PuppetDB service:
```
# service puppetdb stop
```
Generate the new SSL certificates. This command uses the Puppet master’s certificates on the local machine to generate new ones for PuppetDB.
```
# puppetdb ssl-setup
```
Restart the PuppetDB service:
```
# service puppetdb restart
```

As mentioned, my PuppetDB and Puppet master were on the same server. If your Puppet master is on a different server, you will need to copy the certificates from the master manually before running the ssl-setup command.

You can find more detailed instructions in the official documentation: Manually Generating and Preparing Certificates.
