2021云平台复习 搭建
来自CloudWiki
系统准备
安装好两个节点，要求：
（1）controller：内存2G，CPU 2个，自动分区，网卡两块：NAT,仅主机，硬盘建议60G,创建新的虚拟磁盘，镜像centos7.2.虚拟机的名字为学号后两位+姓名全拼+ controller。
（2）compute：内存2G，CPU 2个，手动分区（交换分区4G，根分区25G，/boot 500M），网卡两块：NAT,仅主机，硬盘建议60G,创建新的虚拟磁盘，镜像centos7.2. 虚拟机的名字为学号后两位+姓名全拼+ compute。

创建云主机
利用刚刚创建的云主机类型 和之前创建的镜像cirros 建立一台云主机test01
Nova可对云平台中的实例进行管理，包括创建实例、启动实例、删除实例和实例迁移等操作。
创建密钥
创建一个密钥：
nova keypair-add oskey > oskey.priv
chmod 600 oskey.priv
你查看所有可用的云主机类型
nova flavor-list
查看现在可用的镜像类型
nova image-list
新建立云主机
最后，你利用刚才查到的云主机类型和镜像信息，在后台新建立一个云主机，
nova boot
功能:启动实例。格式:
nova boot --flavor [flavor-id] --key_name oskey --image [image-id] hostname
其中，flavor-id 就是上上步云主机类型表里的id号，建议选tiny的那个，oskey是你刚才创建的密钥，image-id就是上步镜像表里的id号，建议选cirros的那个，hostname换成你自己想起的云主机的名字。
[root@controller ~]# nova boot --flavor 111 --key_name oskey3 --image 12433a25-0b12-4e64-b493-4be576b9490b --nic net-id=7623e6a0-9346-4565-a01d-f8072472d6e6 test01
WARNING: Option "--key_name" is deprecated; use "--key-name"; this option will be removed in novaclient 3.3.0.
