compute node Nova 설치


1. nova 설치
# dnf --enablerepo=centos-openstack-ussuri,powertools,epel -y install qemu-kvm libvirt virt-install libguestfs-tools
- KVM 관련 모듈을 설치합니다.
# systemctl enable --now libvirtd
- libvirtd 서비스를 등록 및 시작합니다.

# nmcli connection add type bridge autoconnect yes con-name br0 ifname br0
- br0의 가상 브릿지를 추가합니다.

# nmcli connection modify br0 ipv4.addresses 10.10.10.30/24 ipv4.method manual
- 가상 브리지의 IP를 추가합니다. ( compute node ip )

# nmcli connection modify br0 ipv4.gateway 10.10.10.10
- 가상 브리지의 GATEWAY를 등록합니다.

# nmcli connection modify br0 ipv4.dns 8.8.8.8
- 가상 브릿지의 DNS를 등록합니다.

# nmcli connection del ens3
- 본래의 네트워크 인터페이스를 삭제합니다.
# nmcli connection add type bridge-slave autoconnect yes con-name ens3 ifname ens3 master br0
- 삭제한 네트워크 인터페이스 대신 브릿지를 매핑시키고 네트워크를 재시작 시킵니다.
- 테스트환경 compute node의 내부대역 IP는 10.10.10.30/24 ens3입니다

# dnf --enablerepo=centos-openstack-ussuri,powertools,epel -y install openstack-nova-compute
- nova 및 관련 모듈을 설치합니다.

# scp /etc/nova/nova.conf compute:/etc/nova/nova.conf
- controller에서 nova의 기본설정파일을 복사합니다.

# vi /etc/nova/nova.conf
[default]

[vnc]
enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip

- nova관련 설정을 추가합니다.

# firewall-cmd --add-port=5900-5999/tcp --permanent
# firewall-cmd --reload
# systemctl enable --now libvirtd
# systemctl enable --now openstack-nova-compute


2. Nova 설치 확인

controller
# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
- DB에 compute의 대한 설정을 업데이트 합니다.

# nova-manage cell_v2 discover_hosts --verbose
- compute 노드가 검색이 안되었을 시 추가적으로 검색합니다.
