openstack 创建实例
1.创建网络
先查看ml2中得配置信息
[root@localhost ml2]# cat /etc/neutron/plugins/ml2/ml2_conf.ini
flat_networks=datacentre
tenant_network_types=vxlan
然后再根据配置详情，创建网络
注意要与上变查看得配置信息一致（flat_networks network_type ）
??为啥查看到的network_type 时 vxlan 但是无法配置通过，需要配置成flat 才能创建成功，如下
命令
neutron net-create --shared --provider:physical_network datacentre \
--provider:network_type flat oldboy[root@controller ~]# neutron net-create --shared --provider:physical_network datacentre \
> --provider:network_type flat oldboy
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

[root@controller ~]# 创建子网
[root@localhost ~(keystone_admin)]# neutron subnet-create --name oldgirl --allocation-pool start=192.168.23.133,end=192.168.23.250 oldboy 192.168.23.0/24

[root@controller ~]# 命令解释
$ neutron subnet-create --name provider \
--allocation-pool start=START_IP_ADDRESS,end=END_IP_ADDRESS \
--dns-nameserver DNS_RESOLVER --gateway PROVIDER_NETWORK_GATEWAY \
provider PROVIDER_NETWORK_CIDR使用提供者物理网络的子网CIDR标记替换``PROVIDER_NETWORK_CIDR``。
将``START_IP_ADDRESS``和``END_IP_ADDRESS``使用你想分配给实例的子网网段的第一个和最后一个IP地址。这个范围不能包括任何已经使用的IP地址。
将 DNS_RESOLVER 替换为DNS解析服务的IP地址。在大多数情况下，你可以从主机``/etc/resolv.conf`` 文件选择一个使用。
将``PUBLIC_NETWORK_GATEWAY`` 替换为公共网络的网关，一般的网关IP地址以 ”.1” 结尾。
例子
公共网络203.0.113.0/24的网关为203.0.113.1。DHCP服务为每个实例分配IP，IP从203.0.113.101 到 203.0.113.200。所有实例的DNS使用8.8.4.4。
2.创建云主机硬件方案
[root@controller ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
+----------------------------+---------+
| Field | Value |
+----------------------------+---------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 1 |
| id | 0 |
| name | m1.nano |
| os-flavor-access:is_public | True |
| properties | |
| ram | 64 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+---------+3、创建密钥对
ssh-keygen -q -N "" -f ~/.ssh/id_rsa
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
4、增加安全组规则
openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default
5、启动一个实例
#先查看 network 信息
[root@controller ~]# openstack network list
+--------------------------------------+--------+--------------------------------------+
| ID | Name | Subnets |

+--------------------------------------+--------+--------------------------------------+

检查实例状态
[root@controller ~]# openstack server list
+--------------------------------------+--------+--------+----------+--------+---------+
| ID | Name | Status | Networks | Image | Flavor |
+--------------------------------------+--------+--------+----------+--------+---------+

+--------------------------------------+--------+--------+----------+--------+---------+
可以在计算节点上找到实例
启动完实例进入
也可以通过dashboard进入到控制界面
windows自己启动得openstack需要配置hosts文件
添加
192.168.23.131 controller
