Puppet is an open-source configuration management tool that helps automate the management of infrastructure. It allows system administrators to define the desired state of their systems using a declarative language and ensures that the systems are configured correctly and consistently.
Puppet follows a client-server architecture:
Add the Puppet repository:
sudo rpm -Uvh https://yum.puppet.com/puppet6-release-el-7.noarch.rpm
Install Puppet Server:
sudo yum install -y puppetserver
Start and enable Puppet Server:
sudo systemctl start puppetserver
sudo systemctl enable puppetserver
Add the Puppet repository:
sudo rpm -Uvh https://yum.puppet.com/puppet6-release-el-7.noarch.rpm
Install Puppet Agent:
sudo yum install -y puppet-agent
Start and enable Puppet Agent:
sudo systemctl start puppet
sudo systemctl enable puppet
Puppet manifests are files written in Puppet’s declarative language. They define the desired state of your system. Here is an example of a simple manifest:
node 'example.com' {
package { 'httpd':
ensure => installed,
}
service { 'httpd':
ensure => running,
enable => true,
}
file { '/var/www/html/index.html':
ensure => file,
content => 'Hello, Puppet!',
}
}
To apply a manifest, use the puppet apply command:
sudo puppet apply /path/to/manifest.pp
Puppet is a powerful tool for automating the management of your infrastructure. By defining the desired state of your systems in Puppet manifests, you can ensure consistency and reliability across your environment.

Puppet is an open-source configuration management tool that helps automate the management of infrastructure. It allows system administrators to define the desired state of their systems using a declarative language and ensures that the systems are configured correctly and consistently.
To get started with Puppet, you need to install the Puppet agent on the systems you want to manage and the Puppet server on a central system. You can then define your configurations in Puppet manifests and apply them to your systems.
