OpenHPC:Headnode install

Basic Initial System Configuration:

OpenHPC is designed to deploy CentOS 7.x based clusters, please install a fresh copy of CentOS 7.x onto a system. Please modify the partitioning and make the “/” partition a reasonable size.

service NetworkManager stop
service iptables stop
chkconfig NetworkManager off
chkconfig iptables off
chkconfig firewalld off
setenforce 0
vi /etc/selinux/config

Modify the system Hostname to use a fully qualified domain name, also modify the network interfaces to have 1x Private interface and 1x Public interface, eno1 must be the private (Provisioning) interface and eno2 can be the public interface. There are alternate ways to specify what interface to use during provision, however with CentOS 7.1 I have been unable to find them.

echo “head.ohpc.net” > /etc/hostname
vi /etc/sysconfig/network-scripts/ifcfg-eno1
vi /etc/sysconfig/network-scripts/ifcfg-eno2

Yum update the system to the latest package versions, install additional packages and reboot.
