openvpn使用单位文件中的确切ExecStart=调用从命令行开始运行systemd：

/usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --script-security 2 --config /etc/openvpn/server.conf /run/openvpn/server.pid

ps ax 确认存在该过程：

1634 ?        Ss     0:00 /usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --script-security 2 --config /etc/openvpn/server.conf --writepid /run/openvpn/

但是systemctl start openvpn@server不成功：

我journalctl | grep ovpn-server | tail -n 100认为它无法分叉：

我也一直在寻找解决办法。我发现可以用注释掉该LimitNPROC行/lib/systemd/system/[email protected]。

不要忘记systemctl daemon-reload在那之后跑。
