两种方式创建云主机
前提交代：上传镜像修改安全组
web创建云主机创建云主机类型创建网络创建云主机
命令行创建云主机首先创建云主机类型创建网络云主机创建
前提
云平台的控股节点(controller)和计算节点(compute)搭建平台时不出错 交代：我们先把我们所有做的东西都给先讲一下 控股节点(controller)的第一块网卡的IP为192.168.43.10；第二块的IP为192.167.44.10 计算节点(compute)的第一块网卡的IP为192.168.43.20；第二块的IP为192.167.44.20 第一块网卡为桥接模式，第二块网卡为NAT模式 上传镜像镜像上传没有什么web上传，只有命令行上传 [root@controller ~]# source /etc/keystone/admin-openrc.sh //这个很重要，我们做这个云主机创建的时候有一句话叫万事先source [root@controller ~]# glance image-create --name "mz" --disk-format qcow2 --container-format bare --progress ] 100% +------------------+--------------------------------------+ | Property | Value | +------------------+--------------------------------------+ | checksum | 3d3e9c954351a4b6953fd156f0c29f5c | | container_format | bare | | created_at | 2021-05-10T11:55:27Z | | disk_format | qcow2 | | id | 841083ae-d1ab-4411-977d-fd43e1c61781 | | min_disk | 0 | | min_ram | 0 | | name | mz | | owner | a519c811bad8464798f2633a934fd48b | | protected | False | | size | 510459904 | | status | active | | tags | [] | | updated_at | 2021-05-10T11:55:31Z | | virtual_size | None | | visibility | shared | +------------------+--------------------------------------+ [root@controller ~]#
我们进入项目点击网络进入安全组，然后点击右侧的管理规则 添加完成的样子：
首先我们进入web界面是这个样子的，第一个是让我们输入的域的名称；第二个是用户名，一般都是admin；第三个是密码，这个是我们自己设置的000000 创建云主机类型
创建网络一定要写外网网卡的IP（就是第二块网卡的IP段）
连接上的样子：
我们还是用着上面的环境跟着来，由于我用的是个人电脑。空间小，运行也不大，所以我在这就将上面创建的云主机删了，空间大的请忽略。 首先创建云主机类型下面在创建云主机类型的时候第一次失败了，原因是没有source，所以我们每当一会不输入命令是再次输入时要先source [root@controller ~]# nova help flavor-create //这个命令可以让我们查询命令行创建云主机类型的格式 usage: nova flavor-create [--ephemeral ] [--swap ] [--rxtx-factor ] [--is-public ] [--description ] Create a new flavor.

进入之后将原有的规则删除，在添加新的规则 
完成的样子： 
后面一步点创建就行 完成的样子： 
点击创建后要等待一会
等待一会之后，完成的样子，我们可以用crt连接
