之前有折腾过《CentOS 6、7下IPSEC/L2TP VPN一键安装脚本》,不稳定、不支持IOS,因此换成pptp,并已经添加到《lnmp一键安装包》。这个脚本可以单独使用,直接复制或下载执行即可,不用依赖安装包的其它脚本。
CentOS 6、7下pptp vpn一键安装脚本,安装如下:
- wget http://mirrors.linuxeye.com/scripts/vpn_centos.sh
- chmod +x ./vpn_centos.sh
- ./vpn_centos.sh
脚本内容如下(vpn_centos.sh):
- #!/bin/bash

- # Check if user is root
- [ $(id -u) != “0” ] && { echo -e “\033[31mError: You must be root to run this script\033[0m”; exit 1; }
- export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
