CentOS 7部署***服务器

1.简介

1.1×××

  在公用网络上建立专用网络的技术。整个×××网络的任意两个节点之间的连接并没有传统专网所需的端到端的物理链路，而是架构在公用网络服务商所提供的网络平台，如Internet、ATM(异步传输模式〉、Frame Relay （帧中继）等之上的逻辑网络，用户数据在逻辑链路中传输。

1.2×××功能

  1）信息包分类

  2）宽带管理

  3）通信量管理

  4）公平宽带

  5）传输保证

2.环境准备

3.部署×××

3.1设置内核转发

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

[root@CentOS 7 ~]# sysctl -p

net.ipv4.ip_forward = 1

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

3.3配置连接网段

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

localip 10.0.0.201

remoteip 172.16.1.200-210

3.4添加×××登陆用户及密码

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

fengyu * 123456 *

3.5启动

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

4.Windows通过×××进入公司内网
