How Install Puppet on RHEL/Centos Linux
This article covers only Monolithic installation of the Enterprise version of Pupper Server and Puppet Agent on RHEL/CentOS 7/6/5.
Systems Requirement
Monolithic hardware requirements
In monolithic installations, hardware requirements differ depending on the number of nodes you’re managing.
| Node volume | Cores | RAM | /opt/ | /var/ | EC2 |
|---|---|---|---|---|---|
| 10 or fewer | 2 | 6 GB | 20 GB | — | m3.large instance |
| Up to 4,000 | 16 + | 32 + GB | 100 GB | 10 GB | c4.4xlarge |
To take advantage of progressively larger hardware, you must configure your environment to use additional resources.
Prerequisites Requirements
Step 1: Enable Dependencies and Puppet Labs Repository On Master
1. The server acting as a puppet master should have its system time set accurately. To set, accurate system time you should probably use NTP service. For more instructions on how to set correct system time with NTP, follow the below article.
2. Once system time is set correctly, you should enable “optional” channel on RHEL distributions only, to install Puppet. For more instructions on how to enable “optional” channel on RHEL systems can be found Here.
3. Once channel is enabled, you can install latest versions of Puppet using Puppet Labs package repository on your correspondent RHEL/CentOS versions.
RHEL/CentOS 7
# rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
RHEL/CentOS 6
# rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm
RHEL/CentOS 5
# rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-5.noarch.rpm Installation Steps
Step 1 Installing and Upgrading Puppet on the Master Server
4. On your master server, run the following command to install Pupper Server, it will install an init script (/etc/init.d/puppetmaster) for executing a test-quality puppet master server.
Do not start puppet master service now.
# yum install puppet-server
5. Next, run the following command to upgrade Puppet to most newest version.
# puppet resource package puppet-server ensure=latest
6. Once upgrade process completes, you will need to restart the puppet master web server to reflect new changes.
# /etc/init.d/puppetmaster restart
Step 3: Installing and Upgrading Puppet on Agent Node
7. Login to your agent node server and run the following command to install Puppet agent. Once you install Puppet agent, you may notice that an init script (/etc/init.d/puppet) has been generated for running the puppet agent daemon.
Do not start puppet agent service now.
# yum install puppet
8. Now upgrade the installed puppet agent to the most recent versions, with the help of following command.
# puppet resource package puppet ensure=latest
9. Once upgrade completes, you will need to restart the puppet service to take new changes.
# /etc/init.d/puppet restart
That’s it! at this moment, your Puppet server and Agent installed successfully, but it isn’t configured properly, to do so you need to follow the post-install and configuration tasks at.
