本文介绍了如何在 CentOS 7 中配置 Ethernet 和 Wifi 接口，使得系统能够同时通过这两种方式接入互联网。首先，通过查看系统文件找到了 Ethernet 接口的名称，然后使用 PPPoE 配置了网络连接，包括输入账号、密码等信息。最后，提供了网络连接的启动和关闭命令。

Why?

I prefer using ethernet to Wifi to access internet. But, I'm afraid, sometimes I have to use Wifi. So, I'm going to configure my CentOS7 to be able to access internet through both Wifi and Ethernet.

Preparation

The ethernet interface/card name is not eth0 on my CentOS7, so I have to find it out.

Way 1:

- ls /etc/sysconfig/network-scripts/ifcfg-*

/etc/sysconfig/network-scripts/ifcfg-enp0s89 (<--- this is my Ethernet name)
/etc/sysconfig/network-scripts/ifcfg-lo (<--- I don't know what it is, whatever, never mind.)
/etc/sysconfig/network-scripts/ifcfg-Tenda_BJ (<--- this is my Wifi router name)

Way2:

- or, follow the GUI "Settings --> Network --> Wired",

Click the settings button on Wired panel, then swith to "Indentity --> Name".

the value of Name is enp0s89

so 'enp0s89' is what I am looking for. This Ethernet name will be used in pppoe configuration later.

Install and setup PPPoE

1. #yum install rp-pppoe

2. You don't have to remove NetworkManager as mentioned in [1]. In fact, if you remove NetworkManager, you can't use Wifi anymore.

3. #pppoe-setup

Enter your Login Name (default user0): <input your xDSL account name>

INTERFACE
(default eth0): <input your Ethernet card name, it may not be eth0!>
