CentOS 7部署***服務器

1.簡介

1.1×××

  在公用網絡上創建專用網絡的技術。整個×××網絡的任意兩個節點之間的鏈接並無傳統專網所需的端到端的物理鏈路，而是架構在公用網絡服務商所提供的網絡平臺，如Internet、ATM(異步傳輸模式〉、Frame Relay （幀中繼）等之上的邏輯網絡，用戶數據在邏輯鏈路中傳輸。

1.2×××功能

  1）信息包分類

  2）寬帶管理

  3）通訊量管理

  4）公平寬帶

  5）傳輸保證

3.部署×××

3.1設置內核轉發

[root@CentOS 7 ~]# echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf 

[root@CentOS 7 ~]# sysctl -p

net.ipv4.ip_forward = 1

3.2安裝PPTP
[root@CentOS 7 ~]# yum install -y pptpd

3.3配置鏈接網段

[root@CentOS 7 ~]# tail -2 /etc/pptpd.conf 

localip 10.0.0.201

remoteip 172.16.1.200-210

3.4添加×××登錄用戶及密碼

[root@CentOS 7 ~]# cat /etc/ppp/chap-secrets

fengyu * 123456 *

3.5啓動

[root@CentOS 7 ~]# systemctl start pptpd.service
