Configure PPPoE on CentOS7

Why?

I prefer using Ethernet to Wi-Fi to access Internet. But, I ' m afraid, sometimes I has to use Wifi. So, I am going to configure my CentOS7 to being able to access Internet through both Wifi and Ethernet.

Preparation

The Ethernet Interface/card name is not eth0 on my CentOS7 and so I has to find it out.

The 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's, whatever, never mind.)
/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-TENDA_BJ (<---this is my Wifi router name)

Way2:

-Or, follow the GUI "Settings--and Network--Wired",

Click the Settings button on Wired panel and then swith to "indentity-to-Name".

The value of Name is ENP0S89

So ' enp0s89 ' are what I am looking for. This Ethernet name is used in PPPoE configuration later.

Install and Setup PPPoE

1. #yum Install Rp-pppoe

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