【云计算】OpenStack单节点allinone部署
等多一会，再ping就好了，可以用Wireshare抓包观察，我这里不出现可能是因为配置低了反应慢。划重点：最小安装，分区可以不分选默认，禁用Kdump，ens33必须打开！选配置分区，可以不配，可以不配！我同学没分区照样能做！可以不分区，选默认也一样，主要我电脑存储空间本来就不够，分区分了个寂寞！挂起虚拟机，拍快照，因为下一步要装大半小时，防止出意外。等了快一个小时了，看到successfull

OpenStack单节点all-in-one部署
工具准备
VMware Workstation Pro 16
CentOS-7-x86_64-DVD-1804.iso
SecureCRT、SecureFX
cirros-0.4.0-x86_64-disk.img
环境搭建
这里一定内存不能少于8G，不然后面安装容易出问题！！还有虚拟化一定要勾上！！！
启动虚拟机centos7
选中文，你要英文好选英语也行。
选配置分区，可以不配，可以不配！！！不影响！！！我同学没分区照样能做！！！
可以不分区，选默认也一样，主要我电脑存储空间本来就不够，分区分了个寂寞！！
ens33要打开，后面下载openstack要网的！！
划重点：最小安装，分区可以不分选默认，禁用Kdump，ens33必须打开！！
设置root密码，待会ssh要用。
安装完成后，登录，查ip地址
使用SecureCRT 连接
ssh成功连上
测下网络，能访问互联网。
安装前的设置

等多一会，再次尝试ping，可以用Wireshare抓包观察。
cirros001能ping网关196.2物理机196.1，也能访问互联网，如下：
win10也能ping通cirros001绑定的浮动ip192.168.196.20
注：如果win10能ping云主机cirros001，云主机cirros001却无法ping通物理机win10，把物理机win10的防火墙关掉！！
抓包验证
云主机cirros001的ip地址为10.10.10.44，抓包时真正通信的是其绑定的浮动ip192.168.196.20
