iptables -flush PuppetĪt this point Puppet should be installed on diamond (and your machine). If you have iptables running, you will have to flush the rules or open the need ports. This part is pretty cool because foreman’s automated installer seems to work quite well, it takes a few minutes, but when completed you should see something like this. Rpm -ivh Add Yum Repos yum-config-manager -enable rhel-6-server-optional-rpms rhel-server-rhscl-6-rpmsĬheck to make sure the Repo was added using yum repolist Installing The Foreman yum -y install Īfter grabbing the packages…finally…run the installer foreman-installer Scl-utils is used for managing the rails console, the rest should be pretty self explanatory. In my case, Installing Basic System Dependencies yum install -y openssh-clients You will want to install The Foreman on your ‘master’ or machine you intend to the be the ‘controller’ of your Cloud. The following steps are based loosely on the So you will see me install some convenience dependencies as well, which I will point out.
To make sure I cover all the dependencies needed I did a minimal install on these machines. My 3 machines in my lab, diamond, ruby and emerald are all running CentOS 6.5. This is really helpful when you have an Openstack Cloud and need to add compute nodes quickly. Using Puppet or Chef and Foreman’s smart proxy architecture, you can easily automate repetitive tasks, quickly deploy applications, and proactively manage change, both on-premise with VMs and bare-metal or in the cloud.” From their website (In other words it builds on well known configuration management systems (puppet in our case) and fully automates ‘things’ to provision and manage bare metal (physical) systems and Cloud Virtual Machines. “Foreman is an open source project that helps system administrators manage servers throughout their lifecycle, from provisioning and configuration to orchestration and monitoring. We will discuss Openstack (in later tutorials, for now The Foreman represents a great first step to setting up a world class Cloud environment. I chose CentOS over Ubuntu or other Linux flavors for this set of tutorials because of it’s ubiquity in enterprise environments and because of RedHat’s leadership in the Openstack ecosystem. If you are not familiar with CentOS it is the Community version of RedHat Linux Enterprise, hence the name C(ommunity)ENT(erprise) O(perating)S(ystem). In this tutorial I will be demonstrating how to install The Foreman on the Linux CentOS 6.5 operating system.
