Installing Puppet master

This section explains how to install puppet-master. Follow this link to check the official installation guide.

If you do not have DNS configured, you must use your hosts file for name resolution. Edit the /etc/hosts file and add the following:

[puppet master ip] puppet puppet-master
[puppet agent ip] puppet-agent

Installation on CentOS/RHEL/Fedora

Install the Puppet yum repository and then the “puppetserver” package. See this index to find the correct rpm file needed to install the puppet repo for your Linux distribution. For example, to install Puppet 7 for CentOS 8 or RHEL 8, do the following:

# sudo rpm -Uvh
# yum -y install puppetserver

Create a symbolic link between the installed binary file and your default binary file:

# ln -s /opt/puppetlabs/bin/puppet /bin
# ln -s /opt/puppetlabs/server/bin/puppetserver /bin

Installation on Debian/Ubuntu

The manifest supports the following releases to install wazuh.

  • Debian: 7 (wheezy), 8 (jessie), 9 (stretch), 10 (buster), 11 (bullseye), 12 (bookworm)

  • Ubuntu: 12.04 (Precise Pangolin), 14.04 (Trusty Tahr), 15.04 (Vivid Vervet), 15.10 (Wily Werewolf), 16.04 (Xenial Xerus), 16.10 (Yakkety Yak), 18.04 (Bionic Beaver), 20.04 (Focal Fossa), 22.04 (Jammy Jellyfish)

Install curl, apt-transport-https and lsb-release:

# apt-get update
# apt-get install curl apt-transport-https lsb-release wget

Install the appropriate Puppet apt repository, and then the “puppetserver” package. See to find the correct deb file to install the Puppet 7 repo for your Linux distribution.

# wget
# dpkg -i puppet7-release-focal.deb
# apt-get update
# apt-get install -y puppetserver

Create a symbolic link between the installed binary file and your default binary file:

# ln -s /opt/puppetlabs/bin/puppet /bin
# ln -s /opt/puppetlabs/server/bin/puppetserver /bin

Memory Allocation

By default, Puppet Server will be 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 Puppet Server memory allocation, you can edit the following init config file.

  • /etc/sysconfig/puppetserver -- CentOS/RHEL/Fedora

  • /etc/default/puppetserver -- Debian/Ubuntu

Replace 2g in the JAVA_ARGS variable 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 JAVA_ARGS="-Xms512m -Xmx512m".


Edit the /etc/puppetlabs/puppet/puppet.conf file, adding this line to the [main] section (create the section if it does not exist), and replacing puppet,puppet-master with your own FQDN:

dns_alt_names = puppet,

Also add the [server] section with the following content in the /etc/puppetlabs/puppet/puppet.conf file replacing puppet-master with your own FQDN:

server =


If you find templatedir=$confdir/templates in the config file, delete that line. It has been deprecated.

For Ubuntu/Debian machines, in case puppetserver does not start. Edit the puppetserver file, /etc/default/puppetserver. Modify the following line to change the memory size to 1G or 512MB:

JAVA_ARGS="-Xms512m -Xmx512m -Djruby.logger.class=com.puppetlabs.jruby_utils.jruby.Slf4jLogger"

Then, start your Puppet Server:

# systemctl start puppetserver
# systemctl enable puppetserver
# systemctl status puppetserver
