我在 Linux 环境 上部署了我的第一个 .netCore 应用程序。使用 Lubuntu 18.04。
我首先尝试使用 apache2，但由于我在从外部访问它时遇到问题，所以我配置了 nginx 并尝试了但没有成功。
我的应用程序使用 dotnet 命令 在端口 5000 上运行，如下所示
usr:/inetpub/www/WebApi$ dotnet WebApi.dll --urls=http://:::5000/
Hosting environment: Production
Content root path: /inetpub/www/WebApi
Now listening on: http://[::]:5000
Application started. Press Ctrl+C to shut down.
这是我读取 --url 输入参数的 Program.cs 文件:
public class Program
{
public static void Main(string[] args)
{
XmlDocument log4netConfig = new XmlDocument();
log4netConfig.Load(File.OpenRead("log4net.config"));
ILoggerRepository repo = LogManager.CreateRepository(Assembly.GetEntryAssembly(),
typeof(log4net.Repository.Hierarchy.Hierarchy));
log4net.Config.XmlConfigurator.Configure(repo, log4netConfig["log4net"]);
//CreateWebHostBuilder(args).Build().Run();
if (args != null && args.Count() > 0)
{
var configuration = new ConfigurationBuilder()
.AddCommandLine(args)
.Build();
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseConfiguration(configuration)
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
else
{
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.UseUrls("http://*:8080/")
.Build();
host.Run();
}
}
}
这是我在 nginx 的可用站点文件夹 中的默认 文件。
server {
listen 80;
server_name _;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;

}
}
如果我转到 localhost，我可以 ping 通在 5000 端口上运行的应用程序。
从另一台计算机转到 192.168.1.46(我的 linux pc 地址)得到 404 错误页面。
这是nmap命令的结果:

我正在努力解决这个问题，我不知道我到底该怎么做才能让它发挥作用。
我唯一可以说的是，如果我的 dotnet 应用程序正在运行，我会收到 404 错误。 如果它没有运行，我会收到 502 Bad Gateway 错误。
我该怎么做才能让它发挥作用？
PS:我把我想到的都加进去了，如果有遗漏的地方，欢迎追问实现
谢谢大家
最佳答案
不知何故，我假设文件在发布过程中损坏了；我删除并复制回了我的 .netCore 项目的所有文件，一切开始正常工作。
也就是说，我会保留这个问题，因为我认为它共享一些可能对其他人有用的配置，因为在这一点上我认为这些是正确的:)
谢谢大家的支持
