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.
Note: If you have any issues with the steps below, submit these to our bug tracker.
Before you begin
Review the supported operating systems and make sure you have a supported version of Java.
Supported operating systems
Puppet provides official packages that install Puppet Server 6 and all of its prerequisites on x86_64 architectures for the following platforms:
Red Hat Enterprise Linux 6, 7, 8
Debian 8 (Jessie), 9 (Stretch), 10 (Buster)
Ubuntu 16.04 (Xenial), 18.04 (Bionic)
SLES 12 SP1
Note: Unlike Puppet agent, Puppet Server is not supported on MacOS.
Puppet Server versions are tested against the following versions of Java:
|6.0-6.5||8, 11 (experimental)|
|6.6 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 Debian 8 (Jessie) or Ubuntu 18.04 (Bionic). To install Puppet Server on Jessie, configure the
jessie-backportsrepository. 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 just testing an installation on a Virtual Machine, this much memory is not necessary. To change the memory allocation, see Running Puppet Server on a VM.
Before you begin: If you're upgrading, stop any existing
puppetserverservice by running
service <service_name> stopor
systemctl stop <service_name>.
a. Enable the Puppet package repositories, if you haven't already done so.
b. Install the Puppet Server package by running one of the following commands:
|Red Hat operating systems|
|Debian and Ubuntu|
c. Start the Puppet Server service:
sudo systemctl start puppetserver
d. Check if you installed the Puppet Server package correctly, by running the following command:
Step Result: The command displays the intended correct version.
What to do next
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.
For RHEL or CentOS, open
For Debian or Ubuntu, open
In your settings, update the line:
# Modify this if you'd like to change the memory allocation, enable JMX, etc JAVA_ARGS="-Xms2g -Xmx2g"
Replace 2g with the amount of memory you want to allocate to Puppet Server. For example, to allocate 1GB of memory, use
JAVA_ARGS="-Xms1g -Xmx1g"; for 512MB, use
