1. 구성방법

• 설치환경 : Virtualbox 5.0.10 + Extention pack• 설치방법 :

– 1. script 실행용 VM 1 대 , openstack 설치용 VM 3 대구성– 2. git Fork or Script file download : (

https://github.com/yoonsungwon/study_devops)– 3. IP Setting (Controller, Network, Compute)– 4. User 생성 (Student), ssh-keygen– 5. 스크립트 실행 (kilo-step-01.sh ~ kilo-step-07.sh)– 6. Compute node 복제하여 compute2 생성 및 설정변경– 7. 환경설정 검토– 8. DVR 설치

2. 특이사항 및 남은과제• 콘솔 접속 시 한 개 VM 만 컨트롤 가능• neutron router-port-list demo-router 명령시 예제와 상이

– 예제 : 192.168.1.1 / 203.0.113.101– 2 팀 : 192.168.1.1(router), 192.168.1.3(snat) / 203.0.113.101(ext-net)

• DHCP 구성 확인• CentOS Image 구성• DBMS 설치 및 AWS 연동

#6. compute 복제 , config 변경

1. Compute Node 복제

2. Hostname 변경3. IP 변경4. Neutron 설정 변경 [root@compute2 neutron]# grep local_ip plugins/ml2/ml2_conf.ini local_ip = 10.0.1.32

#7. 환경설정 검토1. Virtual machine 종류 확인 ( egrep 결과가 0 일경우 qemu 사용 )[root@compute2 neutron]# egrep -c '(vmx|svm)' /proc/cpuinfo0[root@compute2 neutron]# crudini --set /etc/nova/nova.conf libvirt virt_type qemu[root@compute2 neutron]# crudini --get /etc/nova/nova.conf libvirt virt_typeqemu

#8. DVR 설치1. Controller 설치 : sh -x DVR.controller.sh

확인 : sh -x DVR.controller_verify.sh2. Network 설치 : sh -x DVR.network.sh

확인 : sh -x DVR.network_verify.sh3. Compute 설치 : sh -x DVR.compute.sh compute, sh -x DVR.compute.sh compute2

확인 : sh -x DVR.compute_verify.sh compute, sh -x DVR.compute_verify.sh compute2 특이사항 : openvswitch 추가 (br-ex, br-vlan), service 추가 (L3 agent, metadata agent)

4. 설치 검토 (Controller Node 에서 수행 ) – 스크립트 확인 후 대문자로 된 변수 확인 (ex. Instance Name)sh -x DVR.verify.sh

특이사항 : 홈페이지에 게시된 Demo subnet 추가 명령어 오류– Before : neutron subnet-create demo-net --name demo-subnet --gateway 192.168.1.1 192.168.1.0/24– after : neutron subnet-create --name demo-subnet --gateway 192.168.1.1 demo-net 192.168.1.0/24

5. Cirros 기동 시 DHCP IP 를 받아오지 못해 수동으로 설정 필요 ( 설정상 오류 파악중 )ifconfig eth0 192.168.1.xroute add default gw 192.168.1.1
