镜像网络都有了，终于该干正事了，创建一个实例。
一，在控制台创建：
项目--实例--创建实例
按图填就可以
1.png
选择镜像
2.png
选择实例类型，这个类型要事先在管理员里配置。比较简单不细说。
3.png
选择网络，我这里例子选了一个local类型的私有网络
4.png
其它默认就可以，不一一细说。点创建就完成了。
二 ： 命令行创建
[root@controller ~]# openstack server create --flavor computer1 --image centos7.4 --nic net-id=8809a474-8c5e-4cee-bdcd-47ffa7cd955f --security-group 06af95f3-164a-46f1-beb3-db32b285adf6 test08

关于其中的实例名，实力类型，网络，安全组等的查找方法如下。
启动一台实例，您必须至少指定一个类型、镜像名称、网络、安全组、密钥和实例名称。
在控制节点上，获得 凭证来获取只有管理员能执行的命令的访问权限.
1.获取实例类型
$ openstack flavor list

| 1 | m1.tiny | 512 | 1 | 0 | 1 | True |
| 2 | m1.small | 2048 | 20 | 0 | 1 | True |
| 3 | m1.medium | 4096 | 40 | 0 | 2 | True |
