Puppet Server is a required application that runs on the Java Virtual Machine (JVM). It controls the configuration information for one or more managed agent nodes.
Before you begin
Review the supported operating systems and make sure you have a supported version of Java. Note that, unlike Puppet Agent, Puppet Server is not supported on MacOS. If you encounter any issues with the steps below, submit them to our Bug Tracker.
Supported operating systems
Puppet provides official packages that install Puppet Server and all of its prerequisites for the following platforms:
|Red Hat Enterprise Linux||6, 7, 8|
|Debian||9 (Stretch), 10 (Buster)|
|Ubuntu||16.04 (Xenial, amd64 only), 18.04 (Bionic), 20.04 (Focal)|
|SLES||12 SP1 (x86_64)|
If we don't provide a package for your system, you can run Puppet Server from source on any x86_64 Linux server with JDK 1.8 or 11. For more details, visit Running from Source.
Note: For help with non-supported operating systems, architectures, or JRE versions, join our Community Slack.
Puppet Server versions are tested against the following versions of Java:
|6.y and later||8, 11|
|7.y and later||8,11|
Some Java versions may work with other Puppet Server versions, but we do not test or support those cases. Community submitted patches for support greater than Java 11 are welcome. Both Java 8 and 11 are considered long-term support versions and are planned to be supported by upstream maintainers until 2022 or later.
Note: Java 8 runtime packages do not exist in the standard repositories for Ubuntu 18.04 (Bionic). To install Puppet Server on Bionic, enable the universe repository.
Install Puppet Server
Puppet Server is configured to use 2 GB of RAM by default. If you're simply testing an installation on a Virtual Machine, this amount of memory is not necessary. To change the memory allocation, see Running Puppet Server on a VM.
Important: If you're upgrading, stop any existing
puppetserver service by running
service <service_name> stop or
systemctl stop <service_name>.
Enable the Puppet package repositories, if you haven't already done so.
Install the Puppet Server package by running one of the following commands:
Red Hat operating systems:
yum install puppetserver
Debian and Ubuntu operating systems:
apt-get install puppetserver
Start the Puppet Server service:
sudo systemctl start puppetserver
Check if you installed the Puppet Server correctly, by running:
Step Result: If you correctly installed Puppet Server, the command displays the correct version.

Running Puppet Server on a VM
By default, Puppet Server is configured to use 2GB of RAM. However, if you want to experiment with Puppet Server on a VM, you can safely allocate as little as 512MB of memory. To change the Puppet Server memory allocation, you can edit the
init config file.
Open the applicable file:
For RHEL or CentOS, open
For Debian or Ubuntu, open
Update the following line to display the amount of memory you want to allocate to Puppet Server:
# Modify this if you'd like to change the memory allocation, enable JMX, etc JAVA_ARGS="-Xms2g -Xmx2g"
For example, to allocate 1GB of memory, use
JAVA_ARGS="-Xms1g -Xmx1g"; for 512MB, use
