Base OS Installation

  • Base installation of CentOS 7.2 was performed from our PXE server (pxe.boston.co.uk)
  • Nothing more than a vanilla installation

Set a hostname

[root@localhost ~]# hostnamectl set-hostname "head.cix.vscaler.cloud" --static

Configure the infiniband interface

  • Create an /etc/sysconfig/network-scripts/ib0 file with the following contents
DEVICE=ib0
BOOTPROTO=static
IPADDR=172.20.0.1
NETMASK=255.255.0.0
ONBOOT=yes
  • Install ibutils and infiniband-diags
[root@head ~]# yum -y install ibutils infiniband-diags
  • Stop and disable NetworkManager
[root@head ~]# systemctl stop NetworkManager
[root@head ~]# systemctl disable NetworkManager
  • Bring up interface ib0
[root@head ~]# ifup ib0

Update the /etc/hosts file

  • It is necessary update the /etc/hosts file so that references to"controller" resolve to the local system
[root@head ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.18.0.1  controller head
