c# – webapi .net核心得到nginx connect()失败(111：拒绝连接)

概述将我的webapi dotnet核心项目部署到Ubuntu服务器 通过nginx配置kestrel和proxy 我在Program.cs文件中的代码 public class Program { public static void Main(string[] args) { var config = new ConfigurationBuilder() .SetBaseP 将我的webAPI dotnet核心项目部署到ubuntu服务器
通过Nginx配置kestrel和proxy

我在Program.cs文件中的代码

public class Program {  public static voID Main(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())      .UseUrls("http://localhost:5050")      .UseStartup<Startup>()      .Build();     host.Run();  }}

在/ etc / Nginx / sites-available / default和maded symlink中创建文件到/ etc / Nginx / sites-enable / default

server {  Listen 80;  location / {    proxy_pass http://localhost:5050;    proxy_http_version 1.1;    proxy_set_header Upgrade $http_upgrade;    proxy_set_header Connection keep-alive;    proxy_set_header Host $http_host;    proxy_cache_bypass $http_upgrade;  }}

我在/etc/systemd/system/kestrel-project.service中的文件

[Unit]Description=WebAPI .NET Core running on Ubuntu[Service]WorkingDirectory=/var/aspnetcore/projectExecStart=/usr/bin/dotnet /var/aspnetcore/project/project.dllRestart=alwaysRestartSec=10SyslogIDentifIEr=dotnet-projectUser=rootEnvironment=ASPNETCORE_ENVIRONMENT=Production[Install]WantedBy=multi-user.target

对于部署使用此脚本,它一直工作到今天

dotnet restoredotnet builddotnet publishcp -r /root/src/project/bin/DeBUG/netcoreapp2.0/publish/* /var/aspnetcore/project/cp /root/src/project/bin/DeBUG/netcoreapp2.0/project.dll /var/aspnetcore/project/service Nginx restartsystemctl daemon-reloadsystemctl stop kestrel-project.servicesystemctl enable kestrel-project.servicesystemctl start kestrel-project.servicesystemctl status kestrel-project.service

现在,当我在我的本地主机上启动我的webAPI – webAPI运行良好并回答我的请求,但是从服务器我有http错误500和/var/log/Nginx/error.log我看到这个

2018/02/11 19:58:04 [alert] 10584#10584: aborting2018/02/11 20:01:15 [error] 11717#11717: *1 connect() Failed (111:Connection refused) while connecting to upstream,clIEnt: *.*.*.*,server:,request: "GET /List http/1.1",upstream: "http://127.0.1.1:5050/List",host: "*.*.*.*.*"

请帮助我理解这个问题并解决它

没有变化,webAPI工作很长时间,但几天前我开始出现这些错误

@R_404_6120@ 这不是我的问题的答案,但我找到了另一种消除问题的方法

如何使项目再次伟大

使用Docker支持创建新的.net核心项目Web-API

使用Docker将项目代码复制/粘贴到新项目

现在我的代码在Program.cs中

public static voID Main(string[] args) {  BuilDWebHost(args).Run();}public static IWebHost BuilDWebHost(string[] args) =>  WebHost.CreateDefaultBuilder(args)    .UseKestrel()    .UseStartup<Startup>()    .Build();}

我的文件在/ etc / Nginx / sites-available / default中

server {  Listen 80;  server_name API.mydomain.com;  location / {    proxy_pass http://localhost:5050;    proxy_set_header Upgrade $http_upgrade;    proxy_set_header Connection $http_connection;    proxy_set_header Host $host;    proxy_cache_bypass $http_upgrade;  }}

删除文件/etc/systemd/system/kestrel-project.service

在项目中配置Docker

我的Docker文件 – 用于在Docker Hub上自动构建

FROM microsoft/dotnet:latestcopY . /appworkdir /appRUN ["dotnet","restore"]RUN ["dotnet","build"]EXPOSE 5050/tcpENV ASPNETCORE_URLS http://*5050ENV ASPNETCORE_ENVIRONMENT dockerENTRYPOINT ["dotnet","run","--server.urls","http://0.0.0.0:5050"]

我的文件Docker.Compose

FROM microsoft/dotnet:latestworkdir /appEXPOSE 5050:80FROM microsoft/aspnetcore-build:2.0 AS buildworkdir /srccopY *.sln ./copY project/project.csproj project/RUN dotnet restorecopY . .workdir /src/projectRUN dotnet build -c Release -o /appFROM build AS publishRUN dotnet publish -c Release -o /appFROM base AS finalworkdir /appcopY --from=publish /app .ENTRYPOINT ["dotnet","project.dll"]

在Docker Hub注册它是免费的

连接到我的github帐户并为我的项目创建自动构建

然后在服务器端我连接到docker hub

使docker pull dockerprofile / project

然后docker运行-d -p 5050：80 dockerprofile / project

之后一切都运行良好4个月

ps如果您需要更多细节,请问我
