解决办法：
第一种：有人是mac地址的问题
更改了物理网卡或者增加了新设备，或者是克隆时没有完全链接克隆，那么只需要在网络配置文件中加上
HWADDR=XXXXXX 就行了，但是 往往都不能有效结果该问题
通过观察
那么最粗暴直接的办法就是第三种：
第二种：有人是直接VMware下面的连接断开了 或者说没有设置启动自动连接
那么第三种就是观察日志发现有个 NetworkManager的网络服务组件，对他进行以下操作就可以了
[root@mina0 hadoop]# systemctl stop NetworkManager [root@mina0 hadoop]# systemctl disable NetworkManager
然后：重启网卡：
[root@mina0 hadoop]# systemctl restart network
