一、创建基础环境
1、检查网络是否正常
[root@linux-node1 ~]# openstack network agent list
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+
| ID | Agent Type | Host | Availability Zone | Alive | State | Binary |
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+
| 0edfdc1a-f5be-44fe-86d8-4b56b85b1deb | Linux bridge agent | linux-node1.example.com | None | :-) | UP | neutron-linuxbridge-agent |
| 281896e5---95f1-f2d7b8b9d2bc | DHCP agent | linux-node1.example.com | nova | :-) | UP | neutron-dhcp-agent |
| bf75c379-beb3-4a5a-b003-5b136e4fcdf9 | Metadata agent | linux-node1.example.com | None | :-) | UP | neutron-metadata-agent |
| ee34827e-2af6-40ce--ad13902095ce | Linux bridge agent | linux-node2.example.com | None | :-) | UP | neutron-linuxbridge-agent |
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+
2、创建网络
[root@linux-node1 ~]# openstack network create --share --external \
--provider-physical-network provider \
--provider-network-type flat provider
3、查看网络是否创建成功
[root@linux-node1 ~]# openstack network list
+--------------------------------------+----------+---------+
| ID | Name | Subnets |
+--------------------------------------+----------+---------+
| 12d6ee7f-ffd5--b884-8aa74d1ac576 | provider | |
+--------------------------------------+----------+---------+
[root@linux-node1 ~]#
4、创建子网
[root@linux-node1 ~]# openstack subnet create --network provider \
--allocation-pool start=192.168.56.100,end=192.168.56.200 \
--dns-nameserver 223.5.5.5 --gateway 192.168.56.2 \
--subnet-range 192.168.56.0/ provider-subnet
5、 创建云主机类型
[root@linux-node1 ~]# openstack flavor create --id --vcpus --ram --disk m1.nano
6、创建密钥对
[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# ssh-keygen -q -N ""
[root@linux-node1 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
[root@linux-node1 ~]# openstack keypair list
7、添加安全组规则
[root@linux-node1 ~]# openstack security group rule create --proto icmp default
[root@linux-node1 ~]# openstack security group rule create --proto tcp --dst-port default
二、查看创建的实例
1、查看云主机类型
[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# openstack flavor list
2、查看可用的镜像
[root@linux-node1 ~]# openstack image list
3、查看可用的网络
[root@linux-node1 ~]# openstack network list
4、查看可用的安全组
[root@linux-node1 ~]# openstack security group list
三、创建虚拟机
[root@linux-node1 ~]# openstack server create --flavor m1.nano --image cirros \
--nic net-id=5c4d0706-24cd-4d42-ba78-36a05b6c81c8 --security-group default \
--key-name mykey demo-instance
#注意指定网络的时候需要使用ID，而不是名称
四、查看虚拟机
[root@linux-node1 ~]# openstack server list
[root@linux-node1 ~]# openstack console url show demo-instance
