rocky版使用命令启动一个实例

rocky版启动实例官方文档

因为选择的是提供商网络,即网络1,所以参考这个官方文档

1.创建网络

openstack network create 创建网络 --shared 创建共享网络 --provider-physical-network 指定物理网卡名称 provider网络标签 --provider-network-type 指定网络类型 flat是桥接网络 pptfz是网络名称

openstack network create  --share --external \
--provider-physical-network provider \
--provider-network-type flat pptfz

2.创建一个子网

创建一个名为pptfz的子网,依据的网络是第一步中创建的网络pptfz

openstack subnet create --network pptfz \
--allocation-pool start=10.0.0.101,end=10.0.0.250 \
--dns-nameserver 223.5.5.5 --gateway 10.0.0.1 \

openstack flavor create --id 4 --vcpus 2 --ram 4096 --disk 20 m1.medium

4.创建密钥对

ssh-keygen -q -N "" -f ~/.ssh/id_rsa && \
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
+-------------+-------------------------------------------------+
| Field | Value |
+-------------+-------------------------------------------------+

5.创建安全组规则

默认情况下,default安全组适用于所有实例,并包括拒绝对实例进行远程访问的防火墙规则。

许可ICMP(ping)

openstack security group rule create --proto icmp default

6.启动一个实例

6.1 确定实例的选项

6.1.1 在控制器节点上,demo获取凭据以访问仅用户的CLI命令

source /opt/demo-openrc

6.1.2 指定虚拟资源分配配置文件,其中包括处理器,内存和存储,列出可用的规格

openstack flavor list
+----+-----------+------+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+------+------+-----------+-------+-----------+
| 0 | m1.nano | 64 | 1 | 0 | 1 | True |
| 1 | m1.tiny1 | 512 | 5 | 0 | 1 | True |
| 2 | m1.tiny2 | 1024 | 5 | 0 | 1 | True |
| 3 | m1.small | 2048 | 10 | 0 | 1 | True |
| 4 | m1.medium | 4096 | 20 | 0 | 2 | True |
+----+-----------+------+------+-----------+-------+-----------+

6.1.3 列出可用的镜像

openstack image list
+--------------------------------------+--------+--------+
| ID | Name | Status |
+--------------------------------------+--------+--------+
| 94c96aab-d0b3-4340-835c-9a97108d0554 | cirros | active |
+--------------------------------------+--------+--------+

6.1.4 列出可用的网络

openstack network list
+--------------------------------------+-------+--------------------------------------+
| ID | Name | Subnets |
+--------------------------------------+-------+--------------------------------------+
| 26fa223a-231f-419a-a387-750d6eabf3fe | pptfz | ad3d939a-866f-4b2b-9321-29e98fe64f26 |
+--------------------------------------+-------+--------------------------------------+

6.1.5 列出可用的安全组

openstack security group list
+--------------------------------------+---------+------------------------+----------------------------------+------+
| ID | Name | Description | Project | Tags |
+--------------------------------------+---------+------------------------+----------------------------------+------+
| e65b8ec1-3544-414c-94d0-2c87dd6eadbf | default | Default security group | 5b9ccd294c364cc68747df85f9598c89 | [] |
+--------------------------------------+---------+------------------------+----------------------------------+------+

6.2 启动一个实例

官网启动示例

openstack server create --flavor m1.nano --image cirros \
--nic net-id=PROVIDER_NET_ID --security-group default \
--key-name mykey provider-instance

启动实例过程中需要用到net-id,因此使用neutron net-list|awk 'NR==4{print $2}'获取

openstack server create --flavor m1.nano --image cirros \
--nic net-id=`neutron net-list|awk 'NR==4{print $2}'` --security-group default \
--key-name mykey pptfz

neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

创建成功后会在web界面展示

iShot2020-05-2621.40.09

点击控制台登陆虚拟机

⚠️点击控制台后提示找不到controller地址,因为没有做hosts解析,需要先做hosts解析

windows

C:\Windows\System32\drivers\etc\hosts

10.0.0.11 controller

mac

/etc/hosts

10.0.0.11 controller

iShot2020-05-2709.02.08

解析完后刷新浏览器,会看到默认用户是cirros,密码是gocubsgo

iShot2020-05-2709.03.25

查看主机名、IP地址、检查是否能联网
