# 作为反向代理服务器 #

server { 
            listen       8080;                 #监听端口
            server_name  127.0.0.1;			   #服务器ip
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            location / { 
                proxy_pass http://127.0.0.1:8001;      #代理ip加端口
    			proxy_set_header Host $host:$server_port;
    			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    
            }
    
            #error_page  404              /404.html;
    
            # redirect server error pages to the static page /50x.html
            #
            error_page   500 502 503 504  /50x.html;
            location = /50x.html { 
                root   html;
            }
    
            # proxy the PHP scripts to Apache listening on 127.0.0.1:80
            #
            #location ~ \.php$ { 
            #    proxy_pass   http://127.0.0.1;
            #}
    
            # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
            #
            #location ~ \.php$ { 
            #    root           html;
            #    fastcgi_pass   127.0.0.1:9000;
            #    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;
            #}
        }

# 代理项目配置负载均衡 #

1.  创建两个项目，启动

@SpringBootApplication
    @RestController
    public class Nginx1Application { 
    
        public static void main(String[] args) { 
            SpringApplication.run(Nginx1Application.class, args);
        }
    
        @GetMapping("/hello")
        public String hello() { 
            return "hello1";
        }
    }

@SpringBootApplication
    @RestController
    public class Nginx2Application { 
    
        public static void main(String[] args) { 
            SpringApplication.run(Nginx2Application.class, args);
        }
        @GetMapping("/hello")
        public String hello() { 
            return "hello2";
        }
    }

1.  修改nginx配置文件

#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;
     
    	#####添加这里#####
     
        #服务器集群
        upstream nginx.test.com{ 
            server 127.0.0.1:8001 weight=1;
            server 127.0.0.1:8002 weight=2;#可以在这里加权重
        }

1.  hosts文件添加映射：127.0.0.1 [nginx.test.com][]
2.  启动项目和nginx。
3.  访问:[http://nginx.test.com:8081/hello][http_nginx.test.com_8081_hello] hello1和hello2将按照权重配置进行访问。

[nginx.test.com]: http://nginx.test.com
[http_nginx.test.com_8081_hello]: http://nginx.test.com:8081/hello
