openstack-8-创建虚拟机

一 创建虚拟机

创建网络
[root@linux-node3 neutron]# openstack network create --share --external \

–provider-physical-network provider
–provider-network-type flat provider

[root@linux-node3 neutron]# openstack network list

创建子网
[root@linux-node3 ~]# openstack subnet create --network provider \

–allocation-pool start=10.0.0.100,end=10.0.0.200
–dns-nameserver 8.8.8.8 --gateway 10.0.0.2
–subnet-range 10.0.0.0/24 provider

[root@linux-node3 ~]# openstack subnet list

创建m1.nano规格的主机
[root@linux-node3 ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

生成一个键对值
[root@linux-node3 ~]# source demo-openstack.sh
[root@linux-node3 ~]# ssh-keygen -q -N “”
Enter file in which to save the key (/root/.ssh/id_rsa):

[root@linux-node3 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
[root@linux-node3 ~]# openstack keypair list

增加安全组规则
允许 icmp ping)：
[root@linux-node3 ~]# openstack security group rule create --proto icmp default

允许安全 shell (SSH) 的访问
[root@linux-node3 ~]# openstack security group rule create --proto tcp --dst-port 22 default

这里要先用
openstack network list 拿到net-id

创建虚拟机
[root@linux-node3 ~]# openstack server create --flavor m1.nano --image cirros \

–nic net-id=5dc98180-5ec4-4874-a88a-c400dfc3f371 --security-group default
–key-name mykey provider-instance

[root@linux-node3 ~]# openstack server list

报错数据库没有注册

这里没成功，执行下面的 添加计算节点到cell数据库
[root@linux-node3 ~]# su -s /bin/sh -c “nova-manage cell_v2 discover_hosts --verbose” nova
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell ‘cell1’: 27127df3-624d-4112-adab-b44c40204885
Found 0 unmapped computes in cell: 27127df3-624d-4112-adab-b44c40204885

[root@linux-node3 ~]# openstack console url show provider-instance 拿管理页面
