从 mac 开发 machine 将具有多个项目的 .Net 6 应用程序部署到 Linux Elastic Beanstalk 服务器
Deploy .Net 6 app with multiple projects to Linux Elastic Beanstalk Server from mac development machine
我正在尝试将具有多个项目的 .Net 6 应用程序部署到 Linux 来自 mac 开发 machine 的 Elastic Beanstalk 服务器。 api 部署后，我无法查询它。我已经通过 2 种方式完成了 - Just an EC2 instance by following this tutorial, just using command line，以及通过 Elastic beantalk 控制台。所以我有 2 个 EC2 实例。他们都说自己是运行ning.
该项目有一个 Asp.Net 应用程序 (Vepo.Web) 和 5 个用于应用层的辅助项目。 “Vepo”项目只是我制作的一个占位符，因为互联网告诉我当你命名你的 dll 与你的解决方案不同时存在错误；解决方案是“Vepo.sln”。
发布创建的文件如下所示：
我通过 cd 获得了要部署到我的 asp.net 核心网络应用程序 (Vepo.Web) 的源代码，然后 运行 dotnet publish -r linux-x64 --self-contained false --output build，然后转到“Vepo. Web/build”在取景器中。然后select所有文件>右键>压缩（不要压缩父文件夹！）。这会创建“archive.zip”。然后在 Elastic Beanstalk 控制台中上传“archive.zip”。现在它看起来像这样：
但是我好像查询不到api。在 Postman 中，我正在尝试：
ec2-54-xxx-xxx-95.ap-东南-2.compute.amazonaws.com:5001/用户
但我得到：
Error: connect ECONNREFUSED 54.xxx.xxx.95:5000
导航到它给我：
我创建了这些入站规则以允许任何人进入，因为我拼命想进入：
有人可以帮助我在没有获得 404/401 的情况下访问我的网络 API 中的端点吗？如果我遗漏了什么，我会提供任何需要的信息。
更新：我猜当我 ssh 进入应用程序并 运行 这个命令时，应用程序正在 运行ning（不知道如何从邮递员或我的应用程序访问它，在浏览器中访问它不起作用 https://ec2-54-xxx-xxx-53.ap-southeast-2.compute.amazonaws.com:5001/fashionitems/search?searchTerm=B¤tPage=1&pageSize=10):

我猜似乎错误的关键是“正在监听：http://localhost:5000”（那不应该是我的 ec2 实例 public ipv4 地址吗？）和“托管环境：生产“因为我只能确认开发环境正常工作，所以我现在将尝试 运行 在生产版本中本地化。
按照接受的答案添加后，它起作用了。:
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
webBuilder.UseUrls("http://*:5000");
});
答案基本上是尝试总结问题中发表的不同评论。
这个问题可能有很多不同的原因。
要记住的最重要的事情是 EB 提供了一个 nginx 代理来为应用程序提供服务。
By default this proxy 希望您的应用程序侦听端口 5000。
根据您提供的日志，应用程序似乎正常启动并成功连接到数据库。
正如您所指出的，它报告应用程序正在 侦听 http://localhost:5000：这可能不是问题，但也许您的应用程序仅在某些网络 interface/address.
只是为了确定，事实上，最后似乎是解决方案，配置您的应用程序 Kestrel 服务器以侦听掩码 http://*:5000，在您的 [=] 中使用 .UseUrls("http://*:5000") 14=] class，例如。 This article 提供了几个不同的选项来配置应用程序应该在哪里收听。

该项目有一个 Asp.Net 应用程序 (Vepo.Web) 和 5 个用于应用层的辅助项目。 “Vepo”项目只是我制作的一个占位符，因为互联网告诉我当你命名你的 dll 与你的解决方案不同时存在错误；解决方案是“Vepo.sln”。
发布创建的文件如下所示：
我通过 cd 获得了要部署到我的 asp.net 核心网络应用程序 (Vepo.Web) 的源代码，然后 运行 dotnet publish -r linux-x64 --self-contained false --output build，然后转到“Vepo. Web/build”在取景器中。然后select所有文件>右键>压缩（不要压缩父文件夹！）。这会创建“archive.zip”。然后在 Elastic Beanstalk 控制台中上传“archive.zip”。现在它看起来像这样：
但是我好像查询不到api。在 Postman 中，我正在尝试：
ec2-54-xxx-xxx-95.ap-东南-2.compute.amazonaws.com:5001/用户
但我得到：
Error: connect ECONNREFUSED 54.xxx.xxx.95:5000
导航到它给我：
我创建了这些入站规则以允许任何人进入，因为我拼命想进入：
有人可以帮助我在没有获得 404/401 的情况下访问我的网络 API 中的端点吗？如果我遗漏了什么，我会提供任何需要的信息。

我猜似乎错误的关键是“正在监听：http://localhost:5000”（那不应该是我的 ec2 实例 public ipv4 地址吗？）和“托管环境：生产“因为我只能确认开发环境正常工作，所以我现在将尝试 运行 在生产版本中本地化。
按照接受的答案添加后，它起作用了。:
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
webBuilder.UseUrls("http://*:5000");
});
答案基本上是尝试总结问题中发表的不同评论。
这个问题可能有很多不同的原因。
要记住的最重要的事情是 EB 提供了一个 nginx 代理来为应用程序提供服务。
By default this proxy 希望您的应用程序侦听端口 5000。
根据您提供的日志，应用程序似乎正常启动并成功连接到数据库。
正如您所指出的，它报告应用程序正在 侦听 http://localhost:5000：这可能不是问题，但也许您的应用程序仅在某些网络 interface/address.
只是为了确定，事实上，最后似乎是解决方案，配置您的应用程序 Kestrel 服务器以侦听掩码 http://*:5000，在您的 [=] 中使用 .UseUrls("http://*:5000") 14=] class，例如。 This article 提供了几个不同的选项来配置应用程序应该在哪里收听。
