实用的Linux CentOS 7.x系统（亲测腾讯云7.8），免费PPTP协议梯子VPN搭建，最佳用户体验Windows10桌面系统使用。

  • 安全组开放1723、22端口
  • SSH终端登录Linux服务器【宝塔SSH终端】
  • Linux下安装lrzsz,在liux里可代替Ftp上传和下载、终端输入：yum -y install lrzsz
  • 安装名称为 CentOS7-pptp-host1plus.sh 的 bash 脚本
  • CentOS7-pptp-host1plus.sh 脚本内容如下
printhelp() {

echo "
Usage: ./CentOS7-pptp-host1plus.sh [OPTION]
If you are using custom password , Make sure its more than 8 characters. Otherwise it will generate random password for you. 
If you trying set password only. It will generate Default user with Random password. 
example: ./CentOS7-pptp-host1plus.sh -u myusr -p mypass
Use without parameter [ ./CentOS7-pptp-host1plus.sh ] to use default username and Random password
  -u,    --username             Enter the Username
  -p,    --password             Enter the Password
"
}

while [ "$1" != "" ]; do
  case "$1" in
    -u    | --username )             NAME=$2; shift 2 ;;
    -p    | --password )             PASS=$2; shift 2 ;;
    -h    | --help )            echo "$(printhelp)"; exit; shift; break ;;
  esac
done

# Check if user is root
[ $(id -u) != "0" ] && { echo -e "\033[31mError: You must be root to run this script\033[0m"; exit 1; }
