我在 Ubuntu 18.04 上有一个 GMod 服务器，当我通过./run_gmod.sh（作为拥有文件夹/文件的“蒸汽”用户）运行它时它运行良好，其内容是

#!/bin/sh
/datadrive/srcds/gmod/srcds_run -game garrysmod -console -norestart -strictportbind -port 27015 -tickrate 60 -maxplayers 20 \
        +gamemode terrortown +map ttt_minecraft_b5 \
        +host_workshop_collection 1413001823 \
        +sv_setsteamaccount XXXXXXXXXXXX

但是，我想使用 systemctl 将其安装为服务，以便在启动服务器（Azure VM）时自动启动。我创建了一个包含/etc/systemd/system/gmod.service以下内容的文件：

[Unit]
Description=Gmod Server
After=network.target

[Service]
User=steam
WorkingDirectory=/datadrive/srcds/
ExecStart=/datadrive/srcds/gmod/srcds_run -game garrysmod -console -norestart -strictportbind -port 27015 -tickrate 60 -maxplayers 20 +gamemode terrortown +map ttt_minecraft_b5 +host_workshop_collection 1413001823 +sv_setsteamaccount XXXXXXXXXXXX

[Install]
WantedBy=multi-user.target

但是，当我尝试systemctl start gmod得到的日志时，我很奇怪：

Nov 27 23:00:42 Server1 systemd[1]: gmod.service: Current command vanished from the unit file, execution of the command list won't be resumed.

正常日志，通过run_gmod.sh脚本启动时，如下所示：

Auto detecting CPU

mount.cfg adding path: '/datadrive/srcds/gmod/content/css/cstrike'

and then more stuff happens

日志在第二行 ( Using default binary: ./srcds_linux) 之后就出现了分歧，我不明白为什么在运行相同的命令时结果如此不同，只是方式不同。这是 GMod 特有的，还是我的gmod.service文件不正确？我已经尝试过查找，但是将服务器作为服务运行的资源很少，而且.service我发现的示例文件最终会给出类似的错误，所以我认为我应该从头开始。

几年来，我一直在 DigitalOcean 液滴上将一些服务作为 docker 容器运行，最近我认为是时候将其中一个更新到最新版本了（有问题的服务是 ghost 博客平台）。以前，我的工作设置是使用caddy作为反向代理，所以我可以通过转到blog.mydomain.example. Caddyfile 设置如下所示：

blog.mydomain.example {
    proxy / 192.0.2.5:1268
}

其中 IP:port 是本地 ghost docker 容器的端口。

但是，在将我的 ghost 实例更新到最新版本并保持相同的配置后，我收到了一个奇怪的错误。导航到blog.mydomain.example会加载很长一段时间，然后突然重定向到https://192.0.2.5:2368，这当然不起作用，因为这是我的 droplet 上的本地 IP。在网上搜索了很长时间后，我终于找到了解决方法，需要像这样修改我的 Caddyfile：

blog.mydomain.example {
    proxy / 192.0.2.5:1268 {
        transparent
    }
}

代理的caddy 文档页面有一些关于透明的作用：

透明：通过原始请求中的主机信息，正如大多数后端应用程序所期望的那样。
简写：
header_upstream Host {host}
header_upstream X-Real-IP {remote}
header_upstream X-Forwarded-For {remote}
header_upstream X-Forwarded-Proto {scheme}

我还阅读了有关代理类型的这篇文章，但我仍然对使反向代理透明意味着什么以及为什么在这种情况下需要它感到困惑。有人可以解释一下吗？

我在 nginx 反向代理后面的 Digital Ocean 服务器上运行了一些 dockerized 应用程序，确切地说是：https ://github.com/jwilder/nginx-proxy 。我对其进行了配置，以便 app1.domain.com 转到 app1，app2.domain.com 转到 app2，等等。但是，我注意到如果用户执行 public_ip:port 他们仍然可以连接到我的应用程序，即使对于通过 nginx 配置为需要通过 http 身份验证登录的一种。有没有办法配置 nginx，以便只有它们的主机名将被定向到应用程序，并且公共 ip 的任何端口都被拒绝？
