步骤概述:


1、搜寻PPPoE相关软件,本人使用的是rp-pppoe


yum search pppoe


2、使用yum安装rp-pppoe


yum install rp-pppoe -y


3、开始配置PPPoE连接


pppoe-setup


4、输入ISP提供的账户


5、输入以太网卡代号,默认是eth0(注:CentOS 7已不是默认eth0,自行使用ifconfig命令即可找到)


6、配置:若长时间连线,连线会被自动中断(我不干,选no)


7、配置主DNS服务器


8、配置次DNS服务器


9、两次输入账户密码以确认


10、配置普通账户是否有网络连接权限


11、配置防火墙(没有特殊需求选0就OK)


12、配置是否开机自动拨号连接


13、确认刚填写的配置信息


14、连接网络尽情享受吧!


相关命令@ 连接网络:/sbin/ifup ppp0,断开连接:/sbin/ifdown ppp0,查看网络状态:/sbin/pppoe-status

配置rp-pppoe客户端

复制代码

  1 [root@dsp Desktop]# pppoe-setup

  2 Welcome to the PPPoE client setup.  First, I will run some checks on

  3 your system to make sure the PPPoE client is installed properly...

  4 

  5 LOGIN NAME

  6 

  7 Enter your Login Name (default dsp): 12345        # 网络服务提供商提供的账户

  8 

  9 INTERFACE

 10 

 11 Enter the Ethernet interface connected to the PPPoE modem

 12 For Solaris, this is likely to be something like /dev/hme0.

 13 For Linux, it will be ethX, where 'X' is a number.

 14 (default eth0): enp9s0                            # 选择以太网卡,有线网卡

 15 

 16 Do you want the link to come up on demand, or stay up continuously?

 17 If you want it to come up on demand, enter the idle time in seconds

 18 after which the link should be dropped.  If you want the link to

 19 stay up permanently, enter 'no' (two letters, lower-case.)

 20 NOTE: Demand-activated links do not interact well with dynamic IP

 21 addresses.  You may have some problems with demand-activated links.

 22 Enter the demand value (default no): no           # 输入no,否则若长时间连线,连线会被自动中断

 23 

 24 DNS

 25 

 26 Please enter the IP address of your ISP's primary DNS server.

 27 If your ISP claims that 'the server will provide dynamic DNS addresses',

 28 enter 'server' (all lower-case) here.

 29 If you just press enter, I will assume you know what you are

 30 doing and not modify your DNS setup.

 31 Enter the DNS information here: 8.8.8.8           # 主DNS服务器IP,本人使用Google Public DNS

 32 Please enter the IP address of your ISP's secondary DNS server.

 33 If you just press enter, I will assume there is only one DNS server.

 34 Enter the secondary DNS server address here: 8.8.4.4        # 二级DNS服务器IP

 35 

 36 PASSWORD                         # 账户对应的密码,需两次输入以确认无误

 37 

 38 Please enter your Password: 

 39 Please re-enter your Password: 

 40 

 41 USERCTRL

 42 

 43 Please enter 'yes' (three letters, lower-case.) if you want to allow

 44 normal user to start or stop DSL connection (default yes): yes  # 普通用户是否可以启动停止网络连接

 45 

 46 FIREWALLING

 47 

 48 Please choose the firewall rules to use.  Note that these rules are

 49 very basic.  You are strongly encouraged to use a more sophisticated

 50 firewall setup; however, these will provide basic security.  If you

 51 are running any servers on your machine, you must choose 'NONE' and

 52 set up firewalling yourself.  Otherwise, the firewall rules will deny

 53 access to all standard servers like Web, e-mail, ftp, etc.  If you

 54 are using SSH, the rules will block outgoing SSH connections which

 55 allocate a privileged source port.

 56 

 57 The firewall choices are:

 58 0 - NONE: This script will not set any firewall rules.  You are responsible

 59           for ensuring the security of your machine.  You are STRONGLY

 60           recommended to use some kind of firewall rules.

 61 1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation

 62 2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway

 63                 for a LAN

 64 Choose a type of firewall (0-2): 0               # 选 0 吧

 65 

 66 Start this connection at boot time

 67 

 68 Do you want to start this connection at boot time?

 69 Please enter no or yes (default no):yes            # 是否系统启动是就连接网络

 70 

 71 ** Summary of what you entered ** 

 72 

 73 Ethernet Interface: enp9s0

 74 User name:          12345

 75 Activate-on-demand: No

 76 Primary DNS:        8.8.8.8

 77 Secondary DNS:      8.8.4.4

 78 Firewalling:        NONE

 79 User Control:       yes

 80 Accept these settings and adjust configuration files (y/n)? y    # 确认刚才输入的网络配置信息

 81 Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0

 82 Adjusting /etc/resolv.conf

 83   (But first backing it up to /etc/resolv.conf.bak)

 84 Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets

 85   (But first backing it up to /etc/ppp/chap-secrets.bak)

 86   (But first backing it up to /etc/ppp/pap-secrets.bak)

 89 Congratulations, it should be all set up!

 90 

 91 Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0' # rp-pppoe的操作命令

 92 to bring it down.

 93 Type '/sbin/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'

 94 to see the link status.

 95 

 96 [root@dsp Desktop]# /sbin/ifup ppp0      # 启动网络连接

 97 [root@dsp Desktop]# /sbin/pppoe-status    # 查看网络连接状态
