使用DevStack安裝OpenStack Multiple Nodes (以Queens版本為例)

系統版本: Ubuntu Linux 16.04.4

實驗架構圖:

• 安裝前準備:
  下載及安裝git、vim: sudo apt install git vim;
  因為OpenStack需要下載、安裝及設定大量程式，所以需要設定user 權限:
  echo “user ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers;
• 下載devstack: (-b 可鎖定版本，安裝版本為queens)
  git clone http://git.openstack.org/openstack-dev/devstack -b stable/queens;
• 新增及設定local.conf : vim /path/to/devstack/local.conf
  • • Control Node設定

  [[local|localrc]]
  HOST_IP=172.16.0.1 # Control node (local) IP address
  SERVICE_HOST=$HOST_IP
  RABBIT_HOST=$HOST_IP
  DATABASE_HOST=$HOST_IP
  Q_HOST=$HOST_IP
  MULTI_HOST=True
  
  DATABASE_TYPE=mysql
  
  # Log
  USE_SCREEN=True
  SCREEN_LOGDIR=/opt/stack/logs/screen
  LOGFILE=/opt/stack/logs/xstack.sh.log
  LOGDAYS=1
  
  # Images
  FORCE_CONFIG_DRIVE=True
  
  ADMIN_PASSWORD=openstack # 可修改
  DATABASE_PASSWORD=$ADMIN_PASSWORD
  RABBIT_PASSWORD=$ADMIN_PASSWORD
  SERVICE_PASSWORD=$ADMIN_PASSWORD
  SERVICE_TOKEN=$ADMIN_PASSWORD
  
  # Services
  disable_service c-api c-sch c-vol # disable cinder
  
  # Branches
  GLANCE_BRANCH=stable/queens
  HORIZON_BRANCH=stable/queens
  KEYSTONE_BRANCH=stable/queens
  NEUTRON_BRANCH=stable/queens
  NOVA_BRANCH=stable/queens

  • • Compute Node設定 (以Compute Node 1 為例)

  [[local|localrc]]HOST_IP=172.16.0.2 # Compute node (local) IP address
  SERVICE_HOST=172.16.0.1 # Control node IP address
  
  RABBIT_HOST=$SERVICE_HOST
  DATABASE_HOST=$SERVICE_HOST
  MYSQL_HOST=$SERVICE_HOST
  GLANCE_HOSTPORT=$SERVICE_HOST:9292
  
  DATABASE_TYPE=mysql
  
  MULTI_HOST=True
  NOVA_VNC_ENABLED=True
  NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"
  VNCSERVER_LISTEN=$HOST_IP
  VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN
  
  USE_SCREEN=True
  SCREEN_LOGDIR=/opt/stack/logs/screen
  LOGFILE=/opt/stack/logs/xstack.sh.log
  LOGDAYS=1
  
  ADMIN_PASSWORD=openstack
  DATABASE_PASSWORD=$ADMIN_PASSWORD
  RABBIT_PASSWORD=$ADMIN_PASSWORD
  SERVICE_PASSWORD=$ADMIN_PASSWORD
  SERVICE_TOKEN=$ADMIN_PASSWORD
  
  ENABLED_SERVICES=n-cpu,rabbit,q-agt,n-api-meta,placement-client

• 執行安裝程序./stack.sh: /path/to/devstack/stack.sh
  (先安裝Control node，再安裝Compute node)
• Control node執行./discovery_host.sh: /path/to/devstack/tools/discovery_host.sh
  讓OpenStack Control Node 註冊所有Compute Node, 不然Compute Node 將會無法建立VM。
