说明：

eth0：是指第一个物理网卡，具体叫光纤以太网接口卡，学名 Fiber Ethernet Adapter0。物理网卡这里指的是服务器上实际的网络接口设备，这里我服务器上双网卡，在系统中看到多个物理网卡则分别对应 eth0、eth1、eth2…，类似 Windows 装了好几个网卡，会显示本地连接1、本地连接2、本地连接3… -
lo：localhost，127.0.0.1 -
en0：en0 是逻辑上的网络接口名，enx(x是一个数字，代表第几块网卡)是标准以太网接口，ent0 是物理设备，en0 是逻辑设备。查看网络接口信息时，假设看到三个网络接口，en0, en1, en2，但是只有 en1 的状态是 Available 的，说明目前只有这个口已经插上网线在使用，而其它的并没有在用
