VPN(PPTPD)一键安装包,支持Centos6和Centos7.同时支持Openvz和KVM

特别注意:

  1. centos7 会自动停用默认的防火墙,安装 iptables 。所以如果有特别需求的同学就别碰了
  2. 装 vpn 的时候会自动添加 epel 的 yum 源,有洁癖或者特殊需求的请注意
  3. 装 vpn 的时候会自动卸载原来装过的 ppp 和 pptpd ,所以即使想重装也无需自己手动卸载
  4. 有出现安装不了的,无法正常使用的请留言,我尽力解决下。

下载文件, /attachments/1212/vpn_centos_pptpd.sh

安装命令:bash vpn_centos_pptpd.sh

选择 1 :安装 vpn

选择 2 :添加 vpn 账号(安装完后,随时可以使用 bash vpn_centos_pptpd.sh 来选择 2 添加 vpn 账号。当然也可以直接编辑 /etc/ppp/chap-secrets
