Error PuppetDB is running but Puppet Master can t reach it

Question

I have installed a PuppetDB and connected Puppet Master( which is a linux node) with it. I have followed the same steps as in the puppet docs. On checking the PuppetDB logs, i found that PuppetDB is running but my Puppet Master can't reach it. How do i troubleshoot this issue?

Answer 1

• 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 from the Puppet master server. 

telnet <HOST> <PORT>

• 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.

• 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.
