篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了openstack部署之创建第一个实例相关的知识,希望对你有一定的参考价值。

简介

  当完成keystone、glance、nova、neutron组件的部署(部署方法参考之前的博文)之后,我们就可以创建第一个虚拟机实例了,下边具体操作下创建第一个虚拟机实例。

创建第一个实例

创建provider network

  • 设置环境变量,这个在所有服务部署中都会用到,所以如果有报错,首先考虑是否设置环境变量
[[email protected] ~]# source admin-openstack.sh
  • 创建网络
$ openstack network create  --share --external   --provider-physical-network provider   --provider-network-type flat provider

Created a new network:

  • 创建子网
openstack subnet create --network provider   --allocation-pool start=192.168.46.100,end=192.168.46.200 \   #设置创建的实例的地址范围
  --dns-nameserver 223.5.5.5 --gateway 192.168.46.1 \    #设置dns,在此使用的是阿里的DNS,设置网关
  --subnet-range 192.168.46.0/24 provider              #设置子网掩码,网络名称为provider
  • 检查创建的网络和子网

创建云主机规格

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

+----------------------------+---------+
| Field                      | Value   |
+----------------------------+---------+
| OS-FLV-DISABLED:disabled   | False   |
| OS-FLV-EXT-DATA:ephemeral  | 0       |
| disk                       | 1       |

| vcpus                      | 1       |
+----------------------------+---------+

创建key pair

  • 设置demo环境变量
[[email protected] ~]# source demo-openstack.sh
  • 生成key
$ ssh-keygen -q -N ""
$ openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

+-------------+-------------------------------------------------+
| Field       | Value                                           |
+-------------+-------------------------------------------------+
| fingerprint | ee:3d:2e:97:d4:e2:6a:54:6d:0d:ce:43:39:2c:ba:4d |
| name        | mykey                                           |
| user_id     | 58126687cbcc4888bfa9ab73a2256f27                |
+-------------+-------------------------------------------------+

  可以直接使用key登录虚拟机

  • 查看key
[[email protected] ~]# openstack keypair list
+-------+-------------------------------------------------+
| Name  | Fingerprint                                     |
+-------+-------------------------------------------------+
| mykey | 5b:ab:e1:3d:2f:0a:5c:a9:17:b5:d1:0d:85:05:fa:89 |
+-------+-------------------------------------------------+
  • 在安全组中增加两个规则,设置ping和22端口(为了可以ssh连接虚拟机)
$ openstack security group rule create --proto icmp default
