c# – webapi .net核心得到nginx connect()失败(111：拒绝连接)
|
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/project ExecStart=/usr/bin/dotnet /var/aspnetcore/project/project.dll Restart=always RestartSec=10 SyslogIdentifier=dotnet-project User=root Environment=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 restore dotnet build dotnet publish cp -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 restart systemctl daemon-reload systemctl stop kestrel-project.service systemctl enable kestrel-project.service systemctl start kestrel-project.service systemctl 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: aborting 2018/02/11 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 解决方法
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:latest COPY . /app WORKDIR /app RUN ["dotnet","restore"] RUN ["dotnet","build"] EXPOSE 5050/tcp ENV ASPNETCORE_URLS http://*5050 ENV ASPNETCORE_ENVIRONMENT docker ENTRYPOINT ["dotnet","run","--server.urls","http://0.0.0.0:5050"] 我的文件Docker.Compose FROM microsoft/dotnet:latest WORKDIR /app EXPOSE 5050:80 FROM microsoft/aspnetcore-build:2.0 AS build WORKDIR /src COPY *.sln ./ COPY project/project.csproj project/ RUN dotnet restore COPY . . WORKDIR /src/project RUN dotnet build -c Release -o /app FROM build AS publish RUN dotnet publish -c Release -o /app FROM base AS final WORKDIR /app COPY --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 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
