# HW03-1072953-賴約翰 # 安裝OpenStack並建置虛擬機 * 緣由 作業需求，在學校電腦安裝OpenStack * 系統簡介(含硬體說明) 1.vendor_id : GenuineIntel 2.model : 94 3.model name : Intel® Xeon® CPU E3-1220 v5 @ 3.00GHz 4.cpu MHz : 2953.9585 5.core id : 3 6.cpu core : 4 7.cache size : 8192KB 8.電腦作業系統為Ubuntu桌面版本 20.04LTS(5年支援) 64位元版 ![](https://i.imgur.com/YyNXwtQ.jpg) * 安裝過程 參考老師上課ppt(08-p01-Ubuntu Openstack DevStack)以及老師提供網站(http://godleon.blogspot.com/2014/10/openstack-ubuntu-1404-6-vm.html)。 1.確認系統是否跟新 ```javascript= sudo apt-get update sudo apt-get upgrade -y ``` 2.建立一個新的user來設置 openstack ```javascript= sudo useradd -s /bin/bash -d /opt/stack -m stack echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack sudo su - stack ``` 3.下載devstack ```javascript= sudo apt-get install -y git git clone https://git.openstack.org/openstack-dev/devstack git checkout stable/mitaka ``` 4.進入devstack資料夾並建立local.comf檔 ```javascript= cd devstack vim local.conf ``` - local.conf內容 ```javascript= [[local|localrc]] # Password for KeyStone, Database, RabbitMQ and Service ADMIN_PASSWORD=StrongAdminSecret DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD # Host IP - get your Server/VM IP address from ip addr command HOST_IP=192.168.10.100 ``` ![](https://i.imgur.com/zfJ87py.jpg) 5.安裝Openstack ```javascript= ./stack.sh ``` 6.下載Virtual Image ```javascript= wget http://download.cirroscloud.net/0.5.2/cirros-0.5.2-x86_64-disk.img ``` 7.登入openstack web，並source openrc in your shell和Upload it to Glance. ```javascript= source openrc openstack image create \ --container-format bare \ --disk-format qcow2 \ --file cirros-0.5.2-x86_64-disk.img \ Cirros-0.5.2 ``` 8.產生金鑰對並設定儲存位址 ```javascript= ssh-keygen ``` ![](https://i.imgur.com/gbviDc3.jpg) 9.將金鑰對加入openstack並取名為1072953-key ```javascript= nova keypair-add --pub-key /opt/stack/.ssh/loli.pub 1072953-key nova keypair-list ``` ![](https://i.imgur.com/JBSiBbl.jpg) 10.選擇需要開創的虛擬機規格，選用m1.tiny ```javascript= openstack flavor list ``` 11.選擇使用的映象檔 ```javascript= openstack image list ``` 12.查詢可使用的網路 ```javascript= neutron net-list ``` ![](https://i.imgur.com/YQr9lun.png) 13.查詢Security Group ```javascript= openstack security group list ``` 14.啟動VM ```javascript= nova boot --flavor m1.tiny --image 066f7841-c210-4af7-868c-163a8e30a6ef --nic net-id=cbb65f26-2a6e-4b68-8753-64a4a8f70bbe --security-group default --key-name 1072953-key 1072953 ``` ![](https://i.imgur.com/PHz0dp2.jpg) 15.確認VM狀態 ```javascript= nova list ``` 16.存取 VM instance 並測試 ```javascript= nova get-vnc-console 1072943 novnc ``` 17.將取得的網址輸入進瀏覽器中，即可看到虛擬機在運作中，並輸入hostname，可看到主機明成為學號 1072953 ```javascript= hostname ``` ![](https://i.imgur.com/ukGUtBm.jpg) * 結論 這次的作業很複雜，花了很多時間以及和同學討論才好不容易完成。
