场景：VirtualBox 安装CentOS7最小安装的 ，所以没有vim编辑器，就去执行下载指令。yum install vim -y结果发现无法安装吧啦吧啦一大堆提示。我又测试网络是否能ping通，结果发现：虚拟机无法ping通宿主机，ping不通百度。
tips：如果网络通畅无法安装vim，则忽略以下直接去执行：vi /etc/resolv.conf在文件里面添加一行：nameserver 8.8.8.8再测试安装。
无法安装截图：
过程：改过网络模式，改过静动态IP，改过DNS，等等。。。（反正就是虚拟机中各种改）
解决：有时候度娘本娘还是很亲民的，按百度经验中试了下，结果行了！！！！！
特此记录一下，安装完成的时候就把虚拟机的防火墙关了，然后我虚拟机无法ping通宿主机，但是宿主机能ping通虚拟机，我就一直在虚拟机改各种配置，然后才发现是Windows防火墙的问题，我把Windows防火墙全部关闭了都还是不行（不知道是不是操作快或者没重启的原因），最后把虚拟机监控启用才ping通。最后成功安装vim。
