NetCore + Nginx 简单应用

1. Demo项目搭建

• 搭建本地集群

  • 创建.netCore 项目

  • Contronller代码如下

    public class HomeController : ControllerBase
        {
            private readonly ILogger<HomeController> _logger;
            private IConfiguration _iConfiguration;
    
            public HomeController(ILogger<HomeController> logger, IConfiguration configuration)
            {
                this._logger = logger;
                this._iConfiguration = configuration;
            }
            [HttpGet("Home/Get")]
            public IEnumerable<string> Get()
            {
                return new string[] {"value","value2",this._iConfiguration["ip"],this._iConfiguration["port"] };
            }
            [HttpGet]
            public string GetOfId(int id)
            {
                return $@"{id}_{this._iConfiguration["ip"]}:{this._iConfiguration["port"]}";
            }
        }
    

2. Nginx 下载与配置

• 下载 Nginx 的页面

  • 下载链接Nginx

    我选的是 Mainline version下面的版本

• 配置 nginx.conf 文件

  • nginx-1.21.3\conf文件下面nginx.conf

    
    #user  nobody;
    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    
    #pid        logs/nginx.pid;
    
    
    events {
        worker_connections  1024;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
    
        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
        #                  '$status $body_bytes_sent "$http_referer" '
        #                  '"$http_user_agent" "$http_x_forwarded_for"';
    
        #access_log  logs/access.log  main;
    
        sendfile        on;
        #tcp_nopush     on;
    
        #keepalive_timeout  0;
        keepalive_timeout  65;
    
        #gzip  on;
        upstream WebApi{//WebApi 值配置的名字，配置的本地绑定的程序地址
           server 127.0.0.1:8000;

           server 127.0.0.1:8002;
        }
        server {//这个是Nginx 的配置项
            listen       8080;//这个是Nginx 的配置项Ip
            server_name  localhost;
    
            #charset koi8-r;

            location / {
                proxy_pass http://WebApi;//这里需要填写
                root   html;
                index  index.html index.htm;
            }

            #    fastcgi_index  index.php;
            #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            #    include        fastcgi_params;
            #}
    
            # deny access to .htaccess files, if Apache's document root
            # concurs with nginx's one
            #
            #location ~ /\.ht {
            #    deny  all;
            #}
        }

        #    }
        #}
    
    }
    
    

3. 测试

• 启动API

  • 在项目子目录启动cmd

    NginxDemo 是我的项目名字

    dotnet NginxDemo.dll --urls="http://*:8000" --ip="127.0.0.1" --port=8000
    dotnet NginxDemo.dll --urls="http://*:8001" --ip="127.0.0.1" --port=8001
    dotnet NginxDemo.dll --urls="http://*:8002" --ip="127.0.0.1" --port=8002
    

• 启动 nginx.exe

  启动 nginx.exe程序

• 访问 127.0.0.1:8080

  nginx的这里配置的运行机制为: 监听localhost的8080端口，接受到请求转发到webapi。webapi里面定义了3个端口的集群。会轮询转发给配置的集群。

  niginx 默认设置轮询访问
