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.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers in performing related Open-source Software Installation queries.
In this context, we shall look into how to install Puppet on Ubuntu 20.04 LTS.
1. Perform System Update
First, make sure that all your system packages are up-to-date by running these following apt commands in the terminal:
$ sudo apt update
$ sudo apt upgrade
2. Install Puppet on the system
i. Install Puppet Server
Now we download the latest version of Puppet with the following command:
$ wget https://apt.puppetlabs.com/puppet6-release-focal.deb
$ dpkg -i puppet6-release-focal.deb
Then, install the Puppet server using the following command:
$ sudo apt update
$ sudo apt install puppetserver
Start and enable the Puppet Server:
$ sudo systemctl start puppetserver
$ sudo systemctl enable puppetserver
ii. Install Puppet Agent
First, download and install the Puppet repository with the following command:
$ wget https://apt.puppetlabs.com/puppet6-release-focal.deb
$ dpkg -i puppet6-release-focal.deb
Next, run the following commands to install the Puppet agent:
$ sudo apt update
$ sudo apt install puppet-agent
Once has done, you will need to edit the Puppet configuration file and define the Puppet master:
$ nano /etc/puppetlabs/puppet/puppet.conf
Add the following lines:
[main]
certname = puppetclient
server = puppetmaster
Save and close, Then start the Puppet agent service and enable it to start at boot:
$ sudo systemctl start puppet
$ sudo systemctl enable puppet
3. Sign Agent Node Certificate on Master Server
First, on the Puppet master node, run the following command to list all certificate:
$ /opt/puppetlabs/bin/puppetserver ca list
Next, sign all the certificate with the following command:
$ /opt/puppetlabs/bin/puppetserver ca sign --all
Once the Puppet master is signed your client certificate, run the following command on the client machine to test it:
$ /opt/puppetlabs/bin/puppet agent --test
