在 ubuntu 和 nginx 上托管多个 ASP NET Core 站点作为反向代理

Hosting multiple ASP NET Core sites on unbuntu and nginx as reverse proxy

我正在尝试在 Linux、Unbunt 18.04 上托管多个具有不同域的 ASP NET Core 站点,并使用 nginx 作为反向代理。

步骤如下:

1) 在 /etc/nginx/sites-available

中创建新的 .conf 文件

2) 在 /var/www/ 中创建文件夹并在 .net 应用程序中上传

3) 为每个 .conf 文件创建新的 .service 文件

默认的nginx .conf没有改变。

.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,所有站点都被重定向到相同的内容。我的目标是在同一台服务器上托管多个 .net 核心应用程序。 配置应该如何?

我遇到了类似的问题。

您的每个应用程序 nginx 配置文件都应指向 .Net Core 应用程序设置为 运行 的正确端口号。

这在您的每个 .Net Core 应用程序 program.cs.UseUrls() 扩展中确定,例如

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

每个应用程序都需要有不同的端口号,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;
    }
}

希望这对您有所帮助。

服务器上的单个端口是可行的方法,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:

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

server {
    listen        80;
    server_name   domain;

    location /prod {
        rewrite            /prod(.*)  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(.*)  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所示:

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

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

结论:
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/
