环境准备

我这里用workstation创建了一个虚拟机，安装centos7.5 mini系统，这台虚拟机上有两张网卡，一张做openstack管理网，一张做为虚拟机的业务网卡。

我用来测试的VM配置是4C,8G,100G

如果想运行ubuntu cloud images的话最好是8C,16G,100G的配置,当然~~如果你用cirros的话那就随意咯！

基本信息如下

如果安装python-openstackclient出现错误可以临时指定pip源来重新执行python-openstackclient的安装，可以试下下面的命令

pip install -i https://pypi.mirrors.ustc.edu.cn/simple/ python-openstackclient

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple python-openstackclient

[option]可选执行

如果想安装其他的client，请执行以下命令

pip install python-PROJECTclient

请把PROJECT换成cinder或者glance等等等等等等

由于错误的出现，可能需要多次的部署，而有些错误重新部署是不会进行修正的，所以需要将整个环境进行清理:

tools/cleanup-containers                #可用于从系统中移除部署的容器

tools/cleanup-host                      #可用于移除由于残余网络变化引发的docker启动的neutron-agents主机

tools/cleanup-images                    #可用于从本地缓存中移除所有的docker image

登录配置OpenStack

此时就可以访问自己的IP地址了

使用浏览器访问Dashboard，我这里地址就是192.168.6.50

用户名为admin密码为password

1.登录之后需要自己创建实例类型

2.自己创建网络、子网、路由器

3.导入镜像

可以参考https://www.cnblogs.com/tcicy/p/10306306.html

4.创建实例

目前还有个问题，就是我还不知道怎么给虚拟机分配浮动IP地址，没有浮动IP地址的话就没有办法让外部网络设备直接访问ubuntu cloud images instance 18.04.

不过经过这个过程，已经搭建完成OpenStack，比起以前的版本来说那可是相当的简单简洁了。

后面开始你们的表演。
