1.环境介绍

• 由于github的openstack liberty版本的代码已过期，无法使用devstack部署liberty版本，本篇介绍如何使用devstack部署openstack newton版本。
• devstack支持unbuntu 14.04、ubuntu 16.04、centos6和7， 本篇采用ubuntu16.04做为安装操作系统。
• 实验环境
  • devstack-controller：
    • 角色：控制节点+网络节点+存储节点
    • 服务：mysql，rabbit-mq，network-time-server，nova，neutron ，keystone，glance，cinder，neutron-L3-Agent，neutron-DHCP-Agent，neutron-ML2-Plugin
    • 配置：1cpus,4G,3nic(1hostonly,2hostonly,3nat)
    • 网卡： ens33:192.168.56.10 ens34:manual ens35:dhcp
  • devstack-compute：
    • 角色：计算节点
    • 服务，kvm- Hypervisor，nova，Neutron-agent
    • 配置：1cpus,4G,3nic(1hostonly,2hostonly,3nat)
    • 网卡：ens33:192.168.56.10 ens34:manual ens35: dhcp

3. 验证openstack

• 使用浏览器登录http://192.168.56.10 ，默认用户admin，密码admin
• 点击System --> System information

4.devstack openstack服务管理方式

devstack使用screen 来管理服务

5. 删除自动创建的网络

为了得到干净的openstack环境，我们将自动创建的网络删除

delete-router
delete-network
