openstack安装配置—— compute node配置

    计算节点需要配置的主要是nova和neutron的客户端，控制节点在进行资源调度及配置时需要计算节点配合方能实现的，计算节点配置内容相对较少，实际生产环境中，需要配置的计算节点数量相当庞大，那么我们就需要借助ansible或者puppet这样的自动化工具进行了，   废话不多讲，直接进入配置状态。

openstack安装配置—— block node配置

    对于云主机来说,机器可以随时销毁再创建,但数据一定不能,所以就需要数据的持久存储,openstack官方给出的数据存储方案就是cinder模块,cinder模块需要cinder服务端和cinder存储节点共同构成,在本实验中,我们把cinder服务端一并安装在了controller节点上,另行配置一台cinder存储节点,也就是我们的block节点. block节点基础配置 [[email protected] ~]# lscpu Architecture:          x86_6

增加Networking - 前期准备(controller) Networking又叫做Neutron,是Openstack必不可少的组件,它其实是网络虚拟化的实现工具,可以让我们模拟出路由器.交换机.网卡等网络设备. Neutron支持两种网络模式,第一种是非常简单的网络架构,它仅支持是让实例连接外网,不支持自定义网络.路由器以及浮动ip.只有管理员或者授权的用户有权限去管理网络.第二种网络功能比较强大,支持自定义网络管理,支持自建路由器并且也支持浮动ip.即使没有授权的用户也可以管理网络,
