AWS实例上的OpenVPN会中断连接

简介 ：我想在EC2实例（ Ubuntu 16.04 ）上设置一个OpenVPN服务器。 重启后无法configuration接口。

详情 ：

• 图像安装正常，重启很好
• apt update ; apt get openvpn apt update ; apt get openvpn正确apt update ; apt get openvpn OpenVPN
• 使用共享密钥的最小testing设置在从命令行启动时工作（ udp/1945正在监听）

在这个阶段，一切都好。

当重新启动这台机器的状态检查失败

• 不能在EC2主机上运行Ansible playbook
• 在EBS上安装nginx？
• AWS负载均衡器，多个实例 – NAT
• Nginx安装两次，试图安装谷歌pagespeed
• 自动缩放运行多个网站的Web服务器

服务器日志显示机器无法boost其networking接口：

EC2实例configuration其接口的具体方式是什么？

在硬件服务器上的相同的设置工作没有问题，所以我认为这必须是特定于EC2的东西。
