部署dotnet Core Web API

上一步的文章，是我们公司最核心的一个ORM组件,在中标麒麟系统完成了一个插入数据的任务，这一步是将正式的从dot net framework 迁移到 dotnet core 的项目，部署运行在中标麒麟系统中。

项目预览

现有从dotnet framework 迁移过来的一个 dotnet core web api 项目，准备部署中标麒麟系统上测试运行，下面是项目截图：

运行 & 解决

将文件上传到服务器上，然后执行命令运行：

[root@gumis02 API]# dotnet Beyondbit.One.BUA.API.dll

Error:

  An assembly specified in the application dependencies manifest (Beyondbit.One.BUA.API.deps.json) was not found:

    package: 'Microsoft.ApplicationInsights.AspNetCore', version: '2.1.1'

    path: 'lib/netstandard1.6/Microsoft.ApplicationInsights.AspNetCore.dll'

  This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:

    aspnetcore-store-2.0.0-linux-x64.xml;aspnetcore-store-2.0.0-osx-x64.xml;aspnetcore-store-2.0.0-win7-x64.xml;aspnetcore-store-2.0.0-win7-x86.xml

[root@gumis02 API]#

果不既然错误可能会迟到，但是绝不缺席，显示的错误是在开发过程中应用的nuget dll 找不到。这个问题是个小问题，已经有同学写了文章，Fix *.deps.json was not found，文章提到的解决办法：

增加如下一行到 csjproj文件中即可：false

最后csjproj文件看上去像这个样子：

  <PropertyGroup>

    <TargetFramework>netcoreapp2.0</TargetFramework>

    <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest>

  </PropertyGroup>

重新发布项目，然后运行上面的问题已经解决，出现其他的问题：

[root@gumis02 API]# dotnet Beyondbit.One.BUA.API.dll

[root@gumis02 API]#

错误提示确实依赖：

在Starpup.cs 加入一段话：

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

如：

public void ConfigureServices(IServiceCollection services)

  {

      services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

      services.AddMvc(options =>

      {

          options.Filters.Add<IdentityActionFilter>();

          options.Filters.Add<JsonpActionFilter>();

      });

      services.AddDistributedMemoryCache();

      services.AddSession();

      services.AddCors();

  }

最后运行成功了：

[root@gumis02 API]# dotnet Beyondbit.One.BUA.API.dll

Hosting environment: Production

Content root path: /var/ftp/uffice/BUA One/API

Now listening on: http://localhost:5000

Application started. Press Ctrl+C to shut down.

增加多域名，多IP支持

如上面的步骤，在服务器内部使用http://localhost:5000，但是在服务器外用 http://服务器IP:5000 访问的时候访问不到，而且是防火墙在禁用的情况下。在服务器查看端口开放，使用以下命令：

[root@gumis02 ~]# netstat -an | grep 5000

tcp        0      0 127.0.0.1 5000                     :::*                        LISTEN

tcp        0      0 ::1 5000                     :::*                        LISTEN

[root@gumis02 ~]#

可以看到服务器5000端口是针对 127.0.0.1和localhost才可以访问到，这两个都是在服务器内部使用的。

按照.net core 启动域名及端口配置文章中 linux环境一节说明的配置，将代码改造以下，支持在服务器外访问。

首先在解决方案中添加一个文件hosting.josn，内容如下：

{

  "server.urls": "http://*:5000"

}

然后在program.cs文件中修改启动代码：

namespace Beyondbit.One.BUA.API

{

    public class Program

    {

        public static void Main(string[] args)

        {

            BuildWebHost(args).Run();

        }

        public static IWebHost BuildWebHost(string[] args)

        {

            var config = new ConfigurationBuilder()

                        .SetBasePath(Directory.GetCurrentDirectory())

                        .AddJsonFile("hosting.json", optional: true)

                        .Build();

            var host = new WebHostBuilder()

                .UseKestrel()

                .UseConfiguration(config)

                .UseContentRoot(Directory.GetCurrentDirectory())

                .UseIISIntegration()

                .UseStartup<Startup>()

                .Build();

            return host;

        }

    }

}

编译发布到服务器上，运行站点，然后查看命令：

[root@gumis02 ~]# netstat -an | grep 5000

tcp        0      0 ::: 5000                     :::*                        LISTEN

[root@gumis02 ~]#

可以看到 5000前面变成了 :::，而不是第一次的127.0.0.1或::1，这代表5000端口任何ip指向到这个服务器，都可以通过IP:5000访问，在服务器外用浏览器测试看到效果正常。
