OpenShift  StepbyStepGuidetoOpenShiftSetup  In the following description, we are going to set up OpenShift lab environment, which can  be later extended to a bigger cluster. As OpenShift requires master and node setup, we  would need at least two machines hosted on either cloud, physical, or virtual machines.  Step 1:  First install Linux on both the machines, where the Linux 7 should be the least  version. This can be done using the following commands if one has an active Red Hat  subscription.  # subscription-manager repos --disable="*"  # subscription-manager repos --enable="rhel-7-server-rpms"  # subscription-manager repos --enable="rhel-7-server-extras-rpms"  # subscription-manager repos --enable="rhel-7-server-optional-rpms"  # subscription-manager repos --enable="rhel-7-server-ose-3.0-rpms"  # yum install wget git net-tools bind-utils iptables-services bridge-utils  # yum install wget git net-tools bind-utils iptables-services bridge-utils  # yum install python-virtualenv  # yum install gcc  # yum install httpd-tools  17
