Now the Openshift service is up and running, to manage OpenShift installation remotely and access its applications, TCP ports 80, 443, and 8443 need to be opened in your firewall. # systemctl start openshift # systemctl status openshift # chmod u+x /usr/local/bin/start_openshift.sh # mkdir /opt/openshift/ # systemctl daemon-reloadДЄfter reloading daemon, start Openshift service using command below and confirm if its status is active. That's it, now save the file and change the permissions of this file to make it executable and then load the new unit file so that it can be functional. # vim /etc/systemd/system/rvice Д®xecStart=/usr/local/bin/start_openshift.sh Openshift start -public-master=' -master=' Save and close the file and then put the following contents in the newly created file in systemd. # vim /usr/local/bin/start_openshift.sh #!/bin/bash Next, we will create a startup script and systemd unit file by placing our Public and Private IP addresses. # tar -zxf openshift-origin-server-*.tar.gz # cd openshift-origin-server-v1.4.1+3f9807a-linux-64bit/ # mv k* o* /usr/local/sbin/ Then extract the package and change directory to the extracted folder to move all binary files into the '/usr/local/sbin' directory.

Let's run the command below to download the OpenShift binaries from GitHub in the '/tmp' directory. Once we have a docker service up and running, now we are going to setup OpenShift to run as a standalone process managed by systemd.

# systemctl restart rvice Install and configure Openshift Save and close the configuration file, and restart docker service by using below command. # vim /etc/sysconfig/docker # INSECURE_REGISTRY='-insecure-registry' Let's setup DNS to resolve your host and setup FQDN with domain on your VMs.Д¬onfigure the SELINUXTYPE=targeted in the '/etc/selinux/config' file, if its not already done, because Security-Enhanced Linux (SELinux) must be enabled on all of the servers before installing OpenShift Origin else the installation will be failed.

This is ideally a separate host running DNS software and can provide name resolution to hosts and containers running on the platform. OpenShift Origin requires a fully functional DNS server in the environment. Therefore, the recommended size of master host in an OpenShift Origin cluster of 2000 pods would be 2 CPU cores and 3 GB of RAM, in addition to the minimum requirements for a master host of 2 CPU cores and 16 GB of RAM. In a highly available OpenShift Origin cluster with external etcd, a master host should have 1 CPU core and 1.5 GB of memory is required for each 1000 pods. In this article we will be showing you its installation and configuration on a stand alone CentOS 7 server with minimal packages installed on it.

With a cluster of OpenShift hosts in multiple data center locations, you can survive an entire data center going down.

When configured properly, a large OpenShift deployment can offer an easy way to scale your application when demands increase, while providing zero downtime. OpenShift is designed to be a high-availability, scalable application platform. The OpenShift is provided by leveraging Docker and Kubernetes, giving you the ability to have custom, reusable application images. OpenShift provides portability through the DeltaCloud API so customers can migrate deployments to other cloud computing vendor environments. The resources allocated for applications can be automatically or manually scaled as per required so that as demand increases there is no degradation of performance. It provides support for Python, PHP, Perl, Node.js, Ruby, and Java and is extensible so that users can add support for other languages. OpenShift Origin is the open source upstream project that powers OpenShift, Red Hat's container application platform.
