部署dotnet Core Web API

上一步的文章，是我們公司最核心的一個ORM組件,在中標麒麟系統完成了一個插入數據的任務，這一步是將正式的從dot net framework 遷移到 dotnet core 的項目，部署運行在中標麒麟系統中。

項目預覽

現有從dotnet framework 遷移過來的一個 dotnet core web api 項目，準備部署中標麒麟系統上測試運行，下面是項目截圖：

運行 & 解決

將文件上傳到服務器上，然后執行命令運行：

[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]#

果不既然錯誤可能會遲到，但是絕不缺席，顯示的錯誤是在開發過程中應用的nuget dll 找不到。這個問題是個小問題，已經有同學寫了文章，Fix *.deps.json was not found，文章提到的解決辦法：

增加如下一行到 csjproj文件中即可：false
最后csjproj文件看上去像這個樣子：

<PropertyGroup><TargetFramework>netcoreapp2.0</TargetFramework><PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest></PropertyGroup>

重新發布項目，然后運行上面的問題已經解決，出現其他的問題：

[root@gumis02 API]# dotnet Beyondbit.One.BUA.API.dll warn: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[35]No XML encryptor configured.

錯誤提示確實依賴：
在Starpup.cs 加入一段話：

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();}

最后運行成功了：

[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

如上面的步驟，在服務器內部使用http://localhost:5000，但是在服務器外用 http://服務器IP:5000 訪問的時候訪問不到，而且是防火墻在禁用的情況下。 在服務器查看端口開放，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 ~]#

可以看到服務器5000端口是針對 127.0.0.1和localhost才可以訪問到，這兩個都是在服務器內部使用的。
按照.net core 啟動域名及端口配置 文章中 linux環境一節說明的配置，將代碼改造以下，支持在服務器外訪問。

首先在解決方案中添加一個文件hosting.josn，內容如下：

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

然后在program.cs文件中修改啟動代碼：

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;}} }

編譯發布到服務器上，運行站點，然后查看命令：

[root@gumis02 ~]# netstat -an | grep 5000 tcp 0 0 ::: 5000 :::* LISTEN [root@gumis02 ~]#

可以看到 5000前面變成了 :::，而不是第一次的127.0.0.1或::1，這代表5000端口任何ip指向到這個服務器，都可以通過IP:5000訪問，在服務器外用瀏覽器測試看到效果正常。
