In this tutorial, we will show you how to install Puppet on CentOS 8. For those of you who didn’t know, Puppet is an open-source configuration management and server automation framework. It can perform administrative work across a wide array of systems that are primarily defined by a “manifest” file, for the group or type of server(s) being controlled.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Puppet on a CentOS 8.
Prerequisites
- A server running one of the following operating systems: CentOS 8.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Puppet on CentOS 8
Step 1. First, let’s start by ensuring your system is up-to-date.
sudo dnf clean all sudo dnf update
Step 2. Installing Puppet on CentOS 8.
- Install Puppet for Servers
Now we add Puppet repository:
sudo dnf install https://yum.puppetlabs.com/puppetlabs-release-el-8.noarch.rpm
Then, install the Puppet server using the below command:
sudo dnf install puppetserver
Once the installation is complete enable and start the Puppet service:
sudo systemctl start puppetserver sudo systemctl enable puppetserver
- Install Puppet for Clients
Run the following commands to install Puppet clients:
sudo dnf install puppet
Step 3. Configure Firewall.
In a master/client setup, the master server must have port 8140 open to allow for incoming connections from the remote clients. So, configure the firewall to let agents can connect to the master:
sudo firewall-cmd --permanent --add-port=8140/tcp sudo firewall-cmd --reload
Congratulations! You have successfully installed Puppet. Thanks for using this tutorial for installing Puppet in the CentOS 8 system. For additional help or useful information, we recommend you to check the official Puppet website.
