Windows+IDEA+Nginx反向代理本机实现简单集群

刺骨的言语ヽ痛彻心扉 2024-03-17 17:54 80阅读 0赞

先简单创建一个项目，可以是Maven也可以是Spring Initializr，如果是 Maven则需要自己配置启动类

![22587d92e6c844cdb6766dc332141bda.png][]

按照目录路径创建controller类

![131747eac22f4fc8b421380e8df9ad4a.png][]

package com.cloud.SR.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @Author：kkoneone11
     * @name：TestConrtoller1
     * @Date：2023/7/10 12:13
     */
    @RestController
    public class TestConrtoller1 {
        @Autowired
        StringRedisTemplate stringRedisTemplate;
    
        @RequestMapping("/buy")
        public String shopping(){
    //        String result = stringRedisTemplate.opsForValue().get("goods:001");
    //        int total = result == null ? 0 : Integer.parseInt(result);
            System.out.println("输出成功");
            return "ok";
        }
    }

启动后，在下面找到Services栏

![54ad14ab4e94467eb0cac97f89214ed2.png][]

然后找到对应的启动类按下ctrl+D就会弹出这个，就相当于是复制了另一份JVM，相当于两台主机。同时要注意在JVM处要修改对应的端口用**-Dserver.port=**命令

可以看到成功创建

然后下载nginx到本机，记住对应路径，地址如下：[nginx: download][nginx_ download]

![8ac22bfb07cc4eeab63233edbfe90f36.png][]

进入到conf目录修改nginx的配置文件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/json;
    
        sendfile        on;
    
        keepalive_timeout  65;
    
        server {
            listen       8080;
            server_name  localhost;
            #指定前端项目所在位置
            location / {
                root   html;
                index  index.html index.htm;
            }
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    
            location /api {
                default_type application/json;
            	#internal;
            	keepalive_timeout   30s;
            	keepalive_requests  1000;
            	#支持keep-alive
            	proxy_http_version 1.1;
            	rewrite /api(/.*) $1 break;
            	proxy_pass_request_headers on;
            	#more_clear_input_headers Accept-Encoding；
            	proxy_next_upstream error timeout;
            	#proxy_pass http://127.0.0.1：8081；
            	proxy_pass http://backend;
            }
        }
    
        upstream backend {
            server 127.0.0.1:8081 max_fails=5 fail_timeout=10s weight=1;
            server 127.0.0.1:8082 max_fails=5 fail_timeout=10s weight=1;
        }
    }

这里的意思是：发送请求的时候nginx会先监听8080端口，如果有请求发到8080端口然后会把请求转到api路径，然后传输到proxy\_pass代理的http://backend，然后再传到下方的uperstream backend进行端口地址的分配进行轮询。

先启动nginx

start nginx

查看是否有对应进程

tasklist /fi "imagename eq nginx.exe"

重启nginx

nginx -s reload

![6dd9f3086c5347d9a25aa170c38176ca.png][]

查看nginx修改是否正确（注意是要完整的Nginx路径），正确会有successful显示

nginx -t -c D:/software/nginx-1.18.0/conf/nginx.conf

![c43e87f60c83459ebbaa2aa1935937cc.png][]

停止nginx

nginx -s stop

正确关闭nginx

nginx -s quit

重新启动集群

![b41813c6a7544a88a360c2c48071f707.png][]

浏览器输入 [localhost:8080/api/buy][localhost_8080_api_buy]

结果如下则成功完成集群
