centos6.X下pptp vpn一键安装脚本
Aug182016
非常实用的脚本,果断转来。以前分享过的脚本都失效了。。。这个脚本在centos6.x下好用。
1. 下载vpn(CentOS6专用)一键安装包
wget http://www.hi-vps.com/shell/vpn_centos6.sh
chmod a+x vpn_centos6.sh
2. 运行一键安装包
bash vpn_centos6.sh
会有三个选择:
1. 安装VPN服务
2. 修复VPN
3. 添加VPN用户首先输入1,回车,VPS开始安装VPN服务. VPN服务安装完毕后会默认生成一个用户名为vpn,密码为随机数的用户来。
3. 添加VPN用户
bash vpn_centos6.sh
选择3,然后输入用户名和密码,OK
4. 修复VPN服务
如果VPN拨号发生错误,可以试着修复VPN,然后重启VPS
bash vpn_centos6.sh
选择2,然后reboot
下面是具体的脚本:
