Pre-install notes

  1. selinux disabled
  2. firewalld running and allowing internal forwarding of traffic (compute nodes can access repos)
  3. headnode /etc/hosts added entry for headnode, make sure the name 'controller' resolves the headnode also
 [root@head ~]# vi /etc/hosts
 [root@head ~]# ping -c 1 controller
  PING head.ohpc.keele.net (10.10.10.1) 56(84) bytes of data.
  64 bytes from head.ohpc.keele.net (10.10.10.1): icmp_seq=1 ttl=64 time=0.082 ms
  1. enable ntpd on compute nodes; systemctl enable ntpd ; systemctl start ntpd
  2. disable the epel and ohpc repo
 yum-config-manager --disable epel epel-testing OpenHPC_1.0
  [root@node02 yum.repos.d]# grep enable epel* OpenHPC\:1.0.repo
  epel-testing.repo:enabled=0                                                                     
  epel-testing.repo:enabled=0                                                                    
  epel-testing.repo:enabled=0                                              
  epel.repo:enabled=0                                                                              
  epel.repo:enabled=0                                                                              
  epel.repo:enabled=0
