### nginx 负载均衡（url-hash） ###

**nginx 1.7.2版本后，已经集成了url hash功能，可直接使用，不要安装三方模块**

**使用测试**

**应用1：hello-world**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(){
            return "hello world";
        }
    
        @RequestMapping("/hello2")
        public String hello2(){
            return "hello world12";
        }
    
        @RequestMapping("/hello3")
        public String hello3(){
            return "hello world13";
        }
    }

**应用2：hello-world2**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(){
            return "hello world2";
        }
    
        @RequestMapping("/hello2")
        public String hello2(){
            return "hello world22";
        }
    
        @RequestMapping("/hello3")
        public String hello3(){
            return "hello world23";
        }
    }

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**配置文件**

**default.conf**

server {
        listen       80;
        server_name  localhost;
     
        location / {
            proxy_pass http://web-server;
     
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }
     
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
     
    }
     
    upstream web-server {
        hash $request_uri;
    
        server 192.168.57.10:8080;
        server 192.168.57.11:8080;
    }

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**创建容器**

docker run -it -d --net fixed3 --ip 192.168.57.10 \
    -v /usr/nginx/test/hello-world.jar:/usr/local/app.jar \
    --name hello-world common
    
    docker run -it -d --net fixed3 --ip 192.168.57.11 \
    -v /usr/nginx/test/hello-world2.jar:/usr/local/app.jar \
    --name hello-world common
    
    docker run -it -d --net fixed3 --ip 192.168.57.12 \
    -v /usr/nginx/nginx.conf:/etc/nginx/nginx.conf \
    -v /usr/nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf --name nginx nginx
