Question

我试图在Linux上（Unbunt 18.04）托管具有不同域的多个ASP NET Core站点，并使用nginx作为反向代理。

这些步骤是：

1）在/ etc / nginx / sites-available中创建新的.conf文件

2）在/ var / www /中创建文件夹，然后在.net应用中上传

3）为每个.conf文件创建新的.service文件

默认的nginx .conf保持不变。

.conf文件如下所示：

server {
    listen        80;
    server_name   domain;
    location / {
        proxy_pass         http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
}

.service文件如下所示：

[Unit]
Description=Event Registration Example

[Service]
WorkingDirectory=/var/www/example
ExecStart=/usr/bin/dotnet /var/www/example/example.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=dotnet-example
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

使用此配置，即使我部署了几个站点，它们也都被重定向到相同的内容。我的目标是在同一服务器上托管多个.net核心应用程序。配置看起来如何？

我有一个类似的问题。

每个应用程序的nginx配置文件应指向.Net Core应用程序设置为运行的正确端口号。

这是由program.cs扩展名中的每个.Net Core应用程序.UseUrls()确定的，例如

public static IWebHost CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseUrls("http://0.0.0.0:2001")
                .UseStartup<Startup>()
                .Build();

每个应用程序将需要具有不同的端口号，并将其反映在其nginx配置文件中，如下所示：

server {
    listen        80;
    server_name   domain;
    location / {
        proxy_pass         http://localhost:2001;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
}

希望这会有所帮助。

要使用服务器上的单个端口，在ASP.NET Core 3.0中，我的program.cs看起来像这样：

public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.ConfigureKestrel(serverOptions =>
                {

                    serverOptions.Listen(IPAddress.Loopback, 5100);

                })
                .UseStartup<Startup>();
            });
}

如果您想在一台服务器上托管两个或多个应用程序
你需要像这样配置nginx：

<块引用>

cat /etc/nginx/conf.d/domain.conf

server {
    listen        80;
    server_name   domain;

    location /prod {
        rewrite            /prod(.*) $1 break;
        proxy_pass         http://localhost:5000;

        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }

    location /dev {
        rewrite            /dev(.*) $1 break;
        proxy_pass         http://localhost:5001;

        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
}

两个 .Net Core 应用程序的配置如下：

<块引用>

cat /etc/systemd/system/example_prod.service

[Unit]
Description=Example production on .Net Core

[Service]
WorkingDirectory=/var/www/example
ExecStart=/usr/bin/dotnet /var/www/example/example.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=example-production
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false
Environment=ASPNETCORE_URLS=http://localhost:5000

[Install]
WantedBy=multi-user.target

<块引用>

cat /etc/systemd/system/example_dev.service

[Unit]
Description=Example development on .Net Core

[Service]
WorkingDirectory=/var/www/example
ExecStart=/usr/bin/dotnet /var/www/example/example.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=example-development
Environment=ASPNETCORE_ENVIRONMENT=Development
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false
Environment=ASPNETCORE_URLS=http://localhost:5001

[Install]
WantedBy=multi-user.target

总结：
我从一个路径启动了两个应用程序：/var/www/example/example.dll
不同环境：生产和开发
在不同的端口上： localhost:5000 和 localhost:5001

我将 nginx 配置为反向代理：

http://localhost:5000 => http://domain/prod/
http://localhost:5001 => http://domain/dev/

在unbuntu和nginx上托管多个ASP NET Core网站作为反向代理
