Configuration files
Most of the puppet server's configuration files and parameters are kept in the directory /etc/puppetlabs/puppetserver/conf.d. These are all configuration files in the HOCON format.
HOCON stands for Human-Optimized Config Object Notation. It is a file format with the same fundamental structure as JSON but is easier to read.
The puppet server does all of the required changes by reading all .conf files available in conf.d directory. The conf.d directory contains the files and settings listed below.
🖋️ Note: The product.conf file is not automatically included and is optional. To customize settings for the product, create a file called product.conf in the conf.d directory.
Logging
The puppet server logs different things, and a file called logback controls how the puppet server should log. By default, the file is located at /etc/puppetlabs/puppetserver/logback.xml.
Logging HTTP traffic
Puppet Server uses a format similar to Apache to log HTTP activities to a separate file that isn't the main log file.
By default, the following data is recorded for each HTTP request.
Logging Authorization Details
Edit Puppet Server's logback.xml file to enable additional logging related to auth.conf. Only a single message is logged by default when a request is rejected.
💫 Add the following to Puppet Server's logback.xml file to enable one-time logging of the parsed and changed auth.conf file:
<logger name="puppetlabs.trapperkeeper.services.authorization.authorization-service" level="DEBUG"/>
💫 Add the following to Puppet Server's logback.xml file to enable rule-by-rule logging for each request as it is checked for authorization:
<logger name="puppetlabs.trapperkeeper.authorization.rules" level="TRACE"/>
Service Bootstrapping
Puppet server has a feature that we can utilize to enable or disable the CA service. The CA service is active by default, however, you might wish to stop it on some nodes if you're managing a multi-server setup or use an external CA.
The configuration options related to the CA are set in the file /etc/puppetlabs/puppetserver/services.d/ca.cfg.
To enable or disable the service, locate the following lines in the ca.cfg file and change them as necessary:
# To enable the CA service, uncommented the following line
puppetlabs.services.ca.certificate-authority-service/certificate-authority-service
# To disable the CA service, comment out the above line and uncomment the line below
puppetlabs.services.ca.certificate-authority-disabled-service/certificate-authority-disabled-service
Adding Java JARs
During its initial launch, Puppet Server may load any Java Jars that are given. When the puppet server starts, all jar files in /opt/puppetlabs/server/data/puppetserver/jars are loaded into the classpath. JARs placed here are not updated or removed when the Puppet Server is upgraded.
