openstack 实用命令

port

1.创建port(create)

i.随机ip

openstack port create --network public --fixed-ip subnet=sub-public ''

ii.指定ip

openstack port create --network public --fixed-ip subnet=sub-public,ip-address=192.168.130.51 ''

提示:最后的name可以为空，但一定要有

 

2.删除port(delete)

openstack port delete c982c77c-fe12-4e29-9916-56d466a71fe2 c7e7f6d5-20f8-4393-a917-2107b4d59250

 

3.修改port(set,unset)

i.添加指定ip

openstack port set --fixed-ip subnet=sub-public,ip-address=192.168.130.80 427fcb1d-9630-4219-9860-07eac298ae75

ii.删除指定ip

openstack port set --fixed-ip subnet=sub-public,ip-address=192.168.130.80 --no-fixed-ip 3310b8ed-4c72-4473-a9c7-322d36c9d805

iii.network:dhcp属性

openstack network agent list

openstack port set --device 409b88c2-7431-49b8-a272-484c524a096d --device-owner network:dhcp --fixed-ip subnet=sub-public,ip-address=192.168.130.31 --enable ''

 

4.查看port(list,show)

openstack port list

openstack port show 6360f7eb-a2e8-4ded-96b2-17a78b61e088

 

server

1.创建server(create)

i.随机ip

openstack server create --image centos7.3 --flavor m1.micro --security-group default --key-name mykey --user-data centos7_init.sh --availability-zone nova --nic net-id=f1e99b0f-9b5d-4a71-ab90-8b80cae6090c --max 10 selfservice-instance

重要参数:

--max #如果资源足够，生成最大server的数量

--user-data #初始化脚本或cloud-init配置https://docs.openstack.org/developer/python-openstackclient/command-objects/server.html#cmdoption-server-create-user-data

ii.指定ip

openstack server create --image centos7.3 --flavor m1.micro --security-group default --key-name mykey --user-data centos7_init.sh --availability-zone nova --nic net-id=f1e99b0f-9b5d-4a71-ab90-8b80cae6090c,v4-fixed-ip=192.168.130.77 selfservice-instance

 

2.删除server(delete)

openstack server delete 79e7923c-7f16-4483-96d4-69a139381fa6 c7e7f6d5-20f8-4393-a917-2107b4d3lkj230

 

3.修改server

i.添加随机fixed ip

openstack server add fixed ip ebfe4f95-1230-4121-8ec2-ead8ee92330b public

ii.删除指定fixed ip

openstack server remove fixed ip ebfe4f95-1230-4121-8ec2-ead8ee92330b 192.168.130.35

iii.调整大小(cpu,内存,磁盘)

https://docs.openstack.org/user-guide/cli-change-the-size-of-your-server.html

openstack server resize --flavor m1.medium 2f164dad-7ab0-4820-a3ef-63198f34a235

openstack server resize --confirm 2f164dad-7ab0-4820-a3ef-63198f34a235

iv.重建实例(系统重装)

openstack server rebuild --image ubuntu16.04 2f164dad-7ab0-4820-a3ef-63198f34a235

v.重命名

openstack server set --name mynewname 2f164dad-7ab0-4820-a3ef-63198f34a235

vi.标识主机状态

https://docs.openstack.org/nova/pike/admin/support-compute.html#reset-the-state-of-an-instance

https://docs.openstack.org/developer/python-openstackclient/command-objects/server.html#cmdoption-server-set-state

openstack server set --state error2f164dad-7ab0-4820-a3ef-63198f34a235

openstack server set --state active 2f164dad-7ab0-4820-a3ef-63198f34a235

提示:对于正常主机实例，当状态标识为error时，并不会对主机做关闭，删除等操作，只是无法通过ssh等方式对其进行管理，当标识为active后立马一切正常。

 

4.查看server(list,show)

openstack server list

openstack server show 79e7923c-7f16-4483-96d4-69a139381fa6

openstack console url show mynewname

 

ip

openstack ip availability list

openstack ip availability show f1e99b0f-9b5d-4a71-ab90-8b80cae6090c

 

 

老版本补充:

创建网络

neutron net-create provider-194 --shared

--provider:physical_network public --provider:network_type vlan
