我正在尝试让我的 openvpn 服务器和客户端正常工作。我的服务器是 cent os 7 机器，我的客户端是 mint sylvia。
我使用 docker 在 YouTube 上关注了这个教程(链接德语）这是docker的步骤：
curl -fsSL https://get.docker.com/ | sh
systemctl start docker
systemctl status docker systemctl enable docker
docker volume create --name OVPN_DATA docker run -v OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://vpn.servername.com - Hier IP oder Domain von eurem Server einfügen
docker run -v OVPN_DATA:/etc/openvpn --rm -it kylemanna/openvpn ovpn_initpki docker run -v OVPN_DATA:/etc/openvpn -d -p 1194:1194/udp --cap-add=NET_ADMIN kylemanna/openvpn
docker run -v OVPN_DATA:/etc/openvpn --rm -it kylemanna/openvpn easyrsa build-client-full Desktop nopass
docker run -v OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_getclient Desktop > Desktop.ovpn
当我连接终端（sudo openvpn --config file.ovpn）时，它有时会工作，但需要大约 5 分钟才能显示网页。这是我的终端输出：
