Docker极速搭建一个pptp vpn

一句话修改root密码
echo -e "newpwd\nnewpwd" | (passwd root)

以下正式脚本：
yum install -y yum-utils device-mapper-persistent-data  lvm2
yum-config-manager --add-repo  https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io
systemctl enable docker
systemctl start docker

mkdir -p /etc/ppp
touch /etc/ppp/chap-secrets
echo "# Secrets for authentication using PAP" >> /etc/ppp/chap-secrets
echo "# client    server      secret      acceptable local IP addresses" >> /etc/ppp/chap-secrets
echo "tony   *           tony123    *" >> /etc/ppp/chap-secrets

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://uwbns7nz.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

docker run -d --restart=always --privileged --net=host -v /etc/ppp/chap-secrets:/etc/ppp/chap-secrets mobtitude/vpn-pptp

现在用tony/tony123分别作为用户名和密码连接vps的ip就可以了，vpn类型选择pptp.

iptables -I INPUT -p tcp --dport 1725 -j ACCEPT
放行端口
service iptables save
service iptables restart
宝塔默认关闭所有udp，以下命令放行
centos6：iptables -A INPUT -p udp --dport 9001 -j ACCEPT
centos7：firewall-cmd --add-port=9001/udp --permanent
