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,否则背面安装容易出题目!!还有假造化一定要勾上!!!
启动假造机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!!!我同学没分区还是能做!!!
可以不分区,选默认也一样,主要我电脑存储空间原来就不够,分区分了个寂寞!!
ens33要打开,背面下载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暗码,待会ssh要用。
安装完成后,登录,查ip地址
使用SecureCRT 连接
ssh乐成连上
测下网络,能访问互联网。

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
