openstack搭建之-创建实例（13）

一、 创建flat网络的实例

#运行admin环境变量，创建网络类型为flat

. admin-openrc

openstack network create --share \

--provider-physical-network provider \

--provider-network-type flat provider

#创建subnet

openstack subnet create \

--network provider \

--subnet-range 172.16.0.0/16 provider \

--allocation-pool start=172.16.2.100,end=172.16.2.200 \

--gateway 172.16.0.1 \

--dns-nameserver 172.16.0.1 \

--dns-nameserver 8.8.8.8

#验证IP网络

. admin-openrc

ip netns

#创建模板（flvor）

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

openstack flavor create --id 1 --vcpus 1 --ram 1024 --disk 10 chen.nano

#创建钥匙对

. demo-openrc

ssh-keygen -q -N ""

openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

openstack keypair list

#安全组策略设置

openstack security group rule create --proto icmp default

openstack security group rule create --proto tcp --dst-port 22 default

#查看相关信息

. demo-openrc

openstack flavor list

openstack image list

openstack network list

openstack security group list

#创建provider-instance实例（以cirros镜像为例）

openstack server create \

--flavor m1.nano \

--image cirros \

--security-group default \

--key-name mykey \

provider-instance

openstack server list

openstack console url show provider-instance

ping -c 4 openstack.org

ssh cirros@172.16.2.100

#创建存储块并加载到实例

. demo-openrc

openstack volume create --size 1 volume1

openstack volume list

openstack server add volume provider-instance volume1

openstack volume list

二、 创建route网络

#运行环境变量，创建网络类型为flat（外网）

. admin-openrc

openstack network create --share \

--provider-physical-network provider \

--provider-network-type flat provider

openstack subnet create \

--network provider \

--subnet-range 172.0.0/16 provider \

--allocation-pool start=172.16.2.100,end=172.16.2.200 \

--gateway 172.16.0.1 \

--dns-nameserver172.16.0.1 \

--dns-nameserver 8.8.8.8

#创建selfservice网络（内网）

. demo-openrc

openstack network create selfservice

openstack subnet create \

--network selfservice \

--dns-nameserver 8.8.8.8 \

--gateway 192.168.11.1 \

--subnet-range 192.168.11.0/24 selfservice

#更新外部路由

. admin-openrc

neutron net-update provider --router:external

#创建路由

. demo-openrc

openstack router create router

neutron router-interface-add router selfservice

neutron router-gateway-set router provider

#验证

. admin-openrc

ip netns

neutron router-port-list router

#创建模板flvor

openstack flavor create --id 0 --vcpus 1 --ram 1024 --disk 10 chen.nano

#创建钥匙对

. demo-openrc

ssh-keygen -q -N ""

openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

openstack keypair list

#安全组策略

openstack security group rule create --proto icmp default

openstack security group rule create --proto tcp --dst-port 22 default

#查看相关信息

. demo-openrc

openstack flavor list

openstack image list

openstack network list

openstack security group list

#创建selfservice-instance实例（ openstack network list查看selfservice的id）

openstack server create \

--flavor chen1.nano \

--image chen-test \

--nic net-id=8ff69e7c-0762-4243-bfe3-1925752f0e96 \

--security-group default \

--key-name mykey \

selfservice-instance

openstack server list

openstack console url show selfservice-instance

ping -c 4 www.baidu.com

#创建浮点IP，用于通过外部网络访问虚拟机，相当于给虚拟机映射一个外网IP

openstack floating ip create provider

openstack server add floating ip selfservice-instance 172.16.2.150（上一步创建的ip）

openstack server list

ping -c 4 192.168.11.2

ssh cirros@172.16.2.150

#创建存储块

. demo-openrc

openstack volume create --size 10 volume2

openstack volume list

openstack server add volume provider-instance volume2

openstack volume list
