pptp centos 一键安装 CentOS安装
大家好，pptp centos 一键安装相信很多的网友都不是很明白，包括CentOS安装也是一样，不过没有关系，接下来就来为大家分享关于pptp centos 一键安装和CentOS安装的一些知识点，大家可以关注收藏，免得下次来找不到哦，下面我们开始吧！
Centos7系统安装PPTP教程
对于互联网行业工作者，设置动态地址常通过PPTP/L2TP于Windows系统或安卓、苹果手机。若企业客户利用CentOS7系统进行数据抓取，需如何配置PPTP？本教程将提供具体步骤。
首先，确保有CentOS7服务器。其次，检查系统是否支持PPTP。执行如下命令，满足任一即可。
若需安装PPP与PPTPD，执行以下步骤。
1、安装PPP
2、安装PPTPD
注意，安装前需添加EPEL源，更新源列表，然后安装PPTPD。
编辑/etc/pptpd.conf以设定内网IP段。
接着，修改/etc/ppp/options.pptpd，调整DNS设置与日志记录。
编辑/etc/ppp/chap-secrets设定PPTP账号与密码，以支持任意IP连接。
调整内核参数支持内核转发于/etc/sysctl.conf。
对防火墙进行配置，创建规则文件，修改规则，并允许47及1723端口，以及gre协议。
设置转发规则，确保数据包通过eth0和ppp+接口进出。
最后，重启服务器以应用所有更改。
Linux上PPTPVPN的一键安装以及设置开机启动的方法
设置pptp vpn开机启动
有的人懒的重启后手动开启服务，所以下面我再补上开机自动启动pptp vpn和 iptables的命令
复制代码代码如下:#chkconfig pptpd on//开机启动pptp vpn服务
#chkconfig iptables on//开机启动iptables
贴个openvz的pptp vpn一件安装包吧：centos，fedora，redhat 6.x使用的脚本(vps上从没安装过的可以试试这个脚本):点击下载
复制代码代码如下:#!/bin/bash

centos安装配置pptpvpn服务器步骤分享
说明：
服务器操作系统：CentOS 5.X 64位
服务器IP地址：192.168.21.128
实现目的：服务器安装配置pptp软件，对外提供vpn拨号服务
具体操作：
一、安装包下载
1、ppp#安装pptpd需要此软件包
2、pptpd#目前最新版本
下载好之后上传到/usr/local/src目录
二、检查服务器系统环境是否支持安装pptp vpn
1、检查系统内核是否支持MPPE补丁
复制代码代码如下:
modprobe ppp-compress-18&&echo success
显示success说明系统支持MPPE补丁，如果不支持，需要先安装kernel-devel
复制代码代码如下:
yum install kernel-devel
2、检查系统是否开启TUN/TAP支持
cat/dev/net/tun
如果这条指令显示结果为下面的文本，则表明通过：
复制代码代码如下:
cat:/dev/net/tun: File descriptor in bad state
3、检查系统是否开启ppp支持
复制代码代码如下:
cat/dev/ppp
如果这条指令显示结果为下面的文本，则表明通过：
复制代码代码如下:
cat:/dev/ppp: No such device or address
上面三条必须同时满足，否则不能安装pptp vpn
三、安装pptp
复制代码代码如下:
cd/usr/local/src
rpm-ivh ppp-2.4.4-14.1.rhel5.x86_64.rpm#安装ppp
rpm-ivh pptpd-1.4.0-1.rhel5.x86_64.rpm#安装pptp
四、配置pptp
1、vi/etc/ppp/options.pptpd#编辑，添加、修改以下参数
复制代码代码如下:
name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
proxyarp
lock
nobsdcomp
novj
novjccomp
nologfd
ms-dns 8.8.8.8#添加主DNS服务器地址
ms-dns 8.8.4.4#添加备DNS服务器地址
:wq!#保存，退出
2、vi/etc/ppp/chap-secrets#设置pptp拨号用户和密码（可以设置多个用户，每行一个）
复制代码代码如下:
# client server secret IP addresses
osyunweivpnuser01 pptpd 123456*
osyunweivpnuser02 pptpd 1234*
osyunweivpnuser03 pptpd 12345678*
格式：用户名 pptpd密码*
其中*表示为客户端自动分配IP地址
:wq!#保存，退出
3、vi/etc/pptpd.conf#设置pptp服务器IP地址，设置vpn拨入客户端ip地址池
复制代码代码如下:
option/etc/ppp/options.pptpd
logwtmp
localip 172.16.36.1#设置pptp虚拟拨号服务器IP地址（注意：不是服务器本身的IP地址）
remoteip 172.16.36.2-254#为拨入vpn的用户动态分配172.16.36.2～172.16.36.254之间的IP地址复制代码代码如下:
:wq!#保存，退出
/sbin/service pptpd start#启动pptp
/etc/init.d/pptpd stop#关闭
service pptpd restart#重启
chkconfig pptpd on#设置开机启动
五、开启服务器系统路由模式，支持包转发
编辑vi/etc/sysctl.conf
复制代码代码如下:
net.ipv4.ip_forward= 1#设置为1
#net.ipv4.tcp_syncookies= 1#注释掉
复制代码代码如下:
:wq!#保存，退出
/sbin/sysctl-p#使设置立刻生效
六、设置防火墙转发规则
复制代码代码如下:
yum install iptables#安装防火墙
service iptables start#启动防火墙
iptables-t nat-A POSTROUTING-s 172.16.36.0/255.255.255.0-j SNAT--to-source 192.168.21.128#添加规则
iptables-A FORWARD-p tcp--syn-s 172.16.36.0/255.255.255.0-j TCPMSS--set-mss 1356#添加规则
/etc/init.d/iptables save#保存防火墙设置
七、开启pptp服务端口tcp 1723，设置vpn拨入客户端ip地址池172.16.36.0/255.255.255.0通过防火墙
编辑vi/etc/sysconfig/iptables，添加以下代码
复制代码代码如下:
-A RH-Firewall-1-INPUT-p tcp-m state--state NEW-m tcp--dport 1723-j ACCEPT
-A RH-Firewall-1-INPUT-s 172.16.36.0/255.255.255.0-j ACCEPT
:wq!#保存，退出
备注：
复制代码代码如下:
#192.168.21.128为服务器IP地址
#172.16.36.0/255.255.255.0是第四步中设置的pptp虚拟拨号服务器IP地址段
/etc/init.d/iptables restart#重启防火墙
chkconfig iptables on#设置开机启动
cat/etc/sysconfig/iptables#查看防火墙配置文件

八、设置开机自动建立ppp设备节点（系统重新启动后有可能会丢失此文件，导致pptp客户端拨号出现错误619）
编辑vi/etc/rc.d/rc.local，在文件最后添加此行代码
复制代码代码如下:
mknod/dev/ppp c 108 0#在文件最后添加此行代码
:wq!#保存，退出
