UOS通过Nginx托管Net Core服务

UOS 通过 Nginx 托管 .Net Core 服务

硬件环境	软件环境	IP 地址
KVM 虚拟机	UOS 服务器版[X86] 1032	192.168.122.252

UOS + .Net + Nginx

一、准备 .Net 环境

1、解压缩软件包

# mkdir dotnet
# tar -zxf dotnet-runtime-3.1.15-linux-x64.tar.gz -C dotnet/
# tar -zxf dotnet-sdk-3.1.115-linux-x64.tar.gz -C dotnet/

2、优化路径，配置环境变量

# ln -s $HOME/dotent/dotnet /usr/bin/dotnet
# vim .bashrc
export DOTNET_ROOT=$HOME/dotnet
export PATH=$PATH:$DOTNET_ROOT
export MASBuildSDKPath=$HOME/dotnet/sdk/3.1.115/Sdks/
# source .bashrc 

二、编译运行项目

1、创建一个mvc项目

# dotnet new mvc -o ntmvc
The template "ASP.NET Core Web App (Model-View-Controller)" was created successfully.
This template contains technologies from parties other than Microsoft, see https://aka.ms/aspnetcore/3.1-third-party-notices for details.

Processing post-creation actions...
Running 'dotnet restore' on ntmvc/ntmvc.csproj...
  Restore completed in 49.24 ms for /root/ntmvc/ntmvc.csproj.

2、修改 Startup.cs 文件

## 首先切换到项目目录ntmvc，修改Startup.cs文件
# cd ntmvc/
# vim Startup.cs 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
//添加引用
using Microsoft.AspNetCore.HttpOverrides;
....
app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
            
            //添加下面的代码
            app.UseForwardedHeaders(new ForwardedHeadersOptions
            {
                ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
            });

            app.UseAuthentication();

3、生成项目

## 运行下面的命令生成项目
# dotnet publish -c Release
Microsoft (R) Build Engine version 16.4.0+e901037fe for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

  Restore completed in 41.98 ms for /root/ntmvc/ntmvc.csproj.
  ntmvc -> /root/ntmvc/bin/RElases/netcoreapp3.1/ntmvc.dll
  ntmvc -> /root/ntmvc/bin/RElases/netcoreapp3.1/ntmvc.Views.dll
  ntmvc -> /root/ntmvc/bin/RElases/netcoreapp3.1/publish/

运行完后生成一个bin文件夹，bin 文件夹中会包含 Release 文件夹，在 Release 文件夹中的netcoreapp3.1 文件夹中，会包含可以发布的内容，即publish文件夹。

4、运行项目

## 切换到publish 文件夹，运行命令
# dotnet ntmvc.dll
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://localhost:5000
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: https://localhost:5001
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
      Content root path: /root/ntmvc/bin/Release/netcoreapp3.1

5、编写成 service 服务，是指开机自启

# vim /etc/systemd/system/kestrel-ntmvc.service
[Unit]
Description=Example .NET Web MVC Application running on UOS

[Service]
WorkingDirectory=/root/ntmvc
ExecStart=/usr/bin/dotnet /root/ntmvc/bin/Release/netcoreapp3.1/publish/ntmvc.dll
Restart=always
RestartSec=10  # Restart service after 10 seconds if dotnet service crashes
SyslogIdentifier=dotnet-example
User=root
Environment=ASPNETCORE_ENVIRONMENT=Production 

[Install]
WantedBy=multi-user.target

​ 查看结果

# systemctl daemon-reload
# systemctl restart kestrel-ntmvc.service
# systemctl status kestrel-ntmvc.service
● kestrel-ntmvc.service - Example .NET Web MVC Application running on UOS
   Loaded: loaded (/etc/systemd/system/kestrel-ntmvc.service; disabled; vendor preset: enabled)

5月 13 15:36:32 uos-PC dotnet-example[1622]:       Content root path: /root/ntmvc

三、配置 Nginx 托管

1、安装 Nginx

# apt install -y nginx

2、配置 Nginx 代理

# vim /etc/nginx/conf.d/proxy.conf
server {
        listen  80;
        server_name www.yzq1.com;

        location / {
                proxy_pass https://127.0.0.1:5001;
                proxy_redirect             off;
                proxy_set_header         Host             $host;
                proxy_set_header        X-Real-IP         $remote_addr;
                proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
                proxy_set_header    X-Forwarded-Proto $scheme;
                client_max_body_size     10m;
                client_body_buffer_size 128k;
                proxy_connect_timeout     90;
                proxy_send_timeout         90;
                proxy_read_timeout         90;
                proxy_buffers            32 4k;

        }
}

4、检查 Nginx 配置并重启

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# systemctl restart nginx

验证

需要添加/etc/hosts 解析
