언제나 그렇듯!

.bashrc에 환경 변수 설정

다만, /root 의 .bashrc로 생성해서 환경 변수를 넣어 주는것이 편리하다. (추후 "sudo su -" 를 쓰기 편하기 위해)

openSUSE는 eth1로 뜨네?

export CHROOT=/opt/ohpc/admin/images/leap15.2
export eth_provision=eth1
export num_computes=2
export c_ip=("10.0.2.4" "10.0.2.5")
export c_mac=("08:00:27:4b:df:4f" "08:00:27:f9:ca:3f")
export c_name=("openhpc-1" "openhpc-2")
export compute_regex=openhpc-*

export ntp_server=10.0.2.15
export sms_name=master
export sms_ip=10.0.2.15
export sms_eth_internal=eth1
export internal_netmask=255.0.0.0

2020/12/02 - [프로그램 사용/slurm] - openHPC 설치 part 1?

 

+ DHCP로 ip는 받는데 tftp로 파일을 받아오지 못해서 확인해보니

SuSEfirewall2 라는 서비스 대신 firewalld로 suse leap 15 버전에서는 서비스 명칭이 변경되었다.

echo ${sms_ip} ${sms_name} >> /etc/hosts
systemctl disable firewalld
systemctl stop firewalld

 

 

ohpc용 저장소 추가 (특이하게 rpm을 쓰네?)

$ rpm -ivh http://repos.openhpc.community/OpenHPC/2/Leap_15/x86_64/ohpc-release-2-1.leap15.x86_64.rpm

 

ohpc용 기본 패키지 설치

zypper는 처음 써보는데.. 아무생각없이 하라는 대로 했더니 -n 옵션이 reject로 기본 입력되서 설치가 되지 않는다.

그냥 -n 빼고 물어볼 때 t(temporary)나 a(always)를 선택해 주어야 한다.

(sudo su 로 해보니 root는 -n이 y이고 일반 유저는 reject으로 설정이 되어있는 듯 하다)

> sudo zypper -n install ohpc-base ohpc-warewulf
