openstack平台上创建云主机
两种方式创建云主机前提交代：上传镜像web创建云主机修改安全组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

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 < /opt/images/CentOS_7.5_x86_64_XD.qcow2

修改安全组
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
进入之后将原有的规则删除，在添加新的规则
添加完成的样子：
web创建云主机
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
完成的样子：
创建网络
创建网络一定要写外网网卡的IP（就是第二块网卡的IP段）
后面一步点创建就行
完成的样子：
创建云主机
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
连接上的样子：
命令行创建云主机
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 <ephemeral>] [--swap <swap>]
[--rxtx-factor <factor>] [--is-public <is-public>]
[--description <description>]
<name> <id> <ram> <disk> <vcpus>
Create a new flavor.
Positional arguments:
<name> Unique name of the new flavor.
<id> Unique ID of the new flavor. Specifying 'auto'
will generated a UUID for the ID.
<ram> Memory size in MB.
<disk> Disk size in GB.
<vcpus> Number of vcpus
Optional arguments:
--ephemeral <ephemeral> Ephemeral space size in GB (default 0).
--swap <swap> Additional swap space size in MB (default 0).
--rxtx-factor <factor> RX/TX factor (default 1).
--is-public <is-public> Make flavor accessible to the public (default
true).
--description <description> A free form description of the flavor. Limited
to 65535 characters in length. Only printable
characters are allowed. (Supported by API
versions '2.55' - '2.latest')
[root@controller ~]# nova flavor-create aaaa 2 2048 20 2 //失败了，原因没有source
ERROR (CommandError): You must provide a username or user ID via --os-username, --os-user-id, env[OS_USERNAME] or env[OS_USER_ID]
