阅读原文时间:2020年09月29日阅读:5

网上有很多步骤, 讲了很多步骤,废话, 其实不如直接看代码, 而且也能直接运行,快速安装:

rm -f /etc/pptpd.conf
rm -f /etc/ppp
arch=`uname -m`

Download pptpd

-.el6.$arch.rpm ]; then
echo "pptpd-1.3.4-2.el6.$arch.rpm [found]"
else
echo "pptpd-1.3.4-2.el6.$arch.rpm not found!!!download now……"
if ! wget http://lamp.teddysun.com/files/pptpd-1.3.4-2.el6.$arch.rpm;then
echo "Failed to download pptpd-1.3.4-2.el6.$arch.rpm,please download it to $cur_dir directory manually and rerun the install script."
exit
fi
fi

Install some necessary tools

yum -y install net-tools make libpcap iptables gcc-c++ logrotate tar cpio perl pam tcp_wrappers dkms ppp
rpm -ivh pptpd--.el6.$arch.rpm

rm -f /dev/ppp

/proc/sys/net/ipv4/ip_forward
echo "mknod /dev/ppp c 108 0" >> /etc/rc.local
echo "echo 1 > /proc/sys/net/ipv4/ip_forward" >> /etc/rc.local
echo "localip 192.168.8.1" >> /etc/pptpd.conf
echo "remoteip 192.168.8.2-254" >> /etc/pptpd.conf
echo "ms-dns 8.8.8.8" >> /etc/ppp/options.pptpd
echo "ms-dns 8.8.4.4" >> /etc/ppp/options.pptpd

pass=`openssl rand -base64`
if [ "$1" != "" ]

fi

echo "vpn pptpd ${pass} *" >> /etc/ppp/chap-secrets

iptables -t nat -A POSTROUTING -s -j SNAT --to-source `ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk 'NR==1 { print $1}'`
iptables -A FORWARD -p tcp --syn -s -j TCPMSS --set-mss
service iptables save
chkconfig --add pptpd
chkconfig pptpd on
service iptables restart
service pptpd start

echo ""
echo "VPN service installed successfully, your VPN username is vpn, VPN password is ${pass}"
echo "You Can edit /etc/ppp/chap-secrets to add users."

exit

各配置文件如下:

pptpd配置文件 — /etc/pptpd.conf

option配置文件 — /etc/ppp/options.pptpd,这里可以修改dns等

帐号密码文件 — /etc/ppp/chap-secrets

如果登录不了,查看日志:


tail -f /var/log/messages
