Installing Puppet master

In this section it is explained how to install puppet-master. Follow this link to check the official installation guide.

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 5 for CentOS 7 or RHEL 7, do the following:

# rpm -ivh https://yum.puppetlabs.com/puppet5/puppet5-release-el-7.noarch.rpm
# yum -y install puppetserver

Installation on Debian/Ubuntu

The releases supported by the manifest to install Wazuh are as follows:
Ubuntu precise trusty vivid wily xenial yakketi bionic
Debian jessie wheezy stretch sid

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

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

Get the appropriate Puppet apt repository, and then the “puppetserver” package. See https://apt.puppetlabs.com to find the correct deb file to install the Puppet 5 repo for your Linux distribution.

# wget https://apt.puppetlabs.com/puppet5-release-xenial.deb
# dpkg -i puppet5-release-xenial.deb
# apt 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

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 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".

Configuration

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.example.com with your own FQDN:

dns_alt_names = puppet,puppet.example.com

Note

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

Then, restart your Puppet Server to apply changes:

  1. For Systemd:
# systemctl start puppetserver
# systemctl enable puppetserver
  1. For SysV Init:
# service puppetserver start
# update-rc.d puppetserver
