서버 4대로 클러스터링 구축

1. yum 설정 (엔진 서버, 노드 서버)

# 7.x는 EOS되어 yum repo를 Vault로 변경
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/
vi /etc/yum.repos.d/CentOS-Vault.repo
[base]
name=CentOS-7.8.2003 - Base Vault
baseurl=http://vault.centos.org/7.8.2003/os/x86_64/
gpgcheck=0
enabled=1

[updates]
name=CentOS-7.8.2003 - Updates Vault
baseurl=http://vault.centos.org/7.8.2003/updates/x86_64/
gpgcheck=0
enabled=1

[extras]
name=CentOS-7.8.2003 - Extras Vault
baseurl=http://vault.centos.org/7.8.2003/extras/x86_64/
gpgcheck=0
enabled=1
:wq

yum clean all
yum makecache

2. Hosts 설정 (엔진 서버, 노드 서버)

# DNS 서버가 있다면 Hosts 설정 무시

vi /etc/hosts
192.168.13.1    ovirt-engine-01.ovirt.local
192.168.13.2    ovirt-node-01.ovirt.local
192.168.13.3    ovirt-node-02.ovirt.local
192.168.13.4    ovirt-node-03.ovirt.local

3. oVirt 설치 (엔진 서버)

oVirt 레포지토리 수동 생성 (yum으로 설치시 repo안에 만료된 주소가 있어 에러 발생)
vi /etc/yum.repos.d/ovirt-4.3.repo
[ovirt-4.3]
name=oVirt 4.3 Main
baseurl=https://resources.ovirt.org/pub/ovirt-4.3/rpm/el7/

[ovirt-4.3-dependencies]
name=oVirt 4.3 Dependencies

gpgcheck=0

:wq!

yum clean all

Engine 패키지 설치
