1. Create admin VM instance depends properties (network, subnetwork, VM instance specifications)
- Creating a virtual network
source admin-openstack.sh
Format:
openstack network create --share --external \
--provider-physical-network <提供者> \
--provider-network-type flat <网络名称>
# --share 允许所有项目都可以使用该网络
# --external 定义连通外部的虚拟网络
# --provider-physical-network 指定物理网络的提供者，由ml2_conf.ini文件的flat_networks确定
# --provider-network-type flat 映射到虚拟主机的网卡eth0，由linuxbridge_agent.ini文件中的physical_interface_mappings确定
openstack network create --share --external --provider-physical-network provider --provider-network-type flat provider
复制代码- Create a virtual subnet
Format:
openstack subnet create --network <网络名称>
--allocation-pool start=<起始地址>,end=<结束地址> \
--dns-nameserver <域名服务器> --gateway <网关> \
--subnet-range <子网网段> <子网名称>
# --network 指定网络名称，表示该子网用在哪个网段
# --allocation-pool 指定分配的地址池，start设定起始地址，end设置结束地址
# --dns-nameserver 指定域名服务器，可以用8.8.4.4(google),223.5.5.5(阿里云)等等
# --gateway 指定网关，设定宿主机的网关
# --subnet-range 指定子网范围 openstack subnet create --network provider --allocation-pool start=192.168.188.30,end=192.168.188.50 --dns-nameserver 223.5.5.5 --gateway 192.168.188.2 --subnet-range 192.168.188.0/24 provider 复制代码- Creating VM instance specifications
命令格式：
openstack flavor create --id <id号> --vcpus <CPU数量> --ram <内存大小> --disk <磁盘大小> <云主机类型>
openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
复制代码2. Create a VM instance
Use demo user
- Configuration keys
source demo-openstack.sh
#生成秘钥
ssh-keygen -q -N ""
#上传秘钥到openstack
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
#检查效果 openstack keypair list 复制代码- Increase security group
#设置虚拟机ping规则
openstack security group rule create --proto icmp default
#设置虚拟机ssh规则
openstack security group rule create --proto tcp --dst-port 22 default
复制代码3. Start the virtual machine instance
Format:
openstack server create --flavor <云主机规格> --image <镜像名称> \
--nic net-id=<虚拟网络ID> --security-group <安全组> \
--key-name <秘钥名> <虚拟机实例名>
#参数均为前面设置的配置参数
openstack server create --flavor m1.nano --image cirros --nic net-id=782902ce-436a-4d07-aa24-e7aea94fb6c7 --security-group default --key-name mykey provider-instance
复制代码- Check the effect
Gets the virtual machine interface terminal
openstack console url show provider-instance
Browser link url
Here we met Failed to connect to server: problem (code 1006), the open vnc interface, and found the url instead of using a controller ip address, browser suspected resolve the problem. Then modify the C under the windows system: \ Windows \ System32 \ drivers \ etc \ hosts file DNS, the controller is mapped to a control node ip address, the error problem is solved.
Open vnc interface later found to be black, do not know how to solve, and so on for a while as well. It estimates the physical machine configuration is not too card ...
Ssh connection
to sum up
Individuals consider themselves to be the entry point to learn OpenStack, the open-source software can be said is quite complex and cumbersome, if you want more in-depth study and practice the use of its capability, long way to go.
