windowsnginx配置负载均衡

1、官网下载nginx稳定版

nginx官网

2、下载之后，解压到指定的目录

3、在nginx目录下打开cmd控制台，输入start nginx ，然后在浏览器页面输入localhost，出现如下界面则表示安装成功。默认监听80端口号。

 4、负载均衡配置(打开nginx.conf)

weight代表权重越大则访问该服务的次数占比就越多

设置负载均衡配置(lezu可以任意命令)

     }

配置完成之后通过nginx -s reload命令来刷新配置文件

5、springboot启动两个项目设置端口

--server.port=8080

--server.port=8081

6、通过接口测试工具进行测试访问

http://localhost/deductStock1

1.  
   /**
2.  
   * 单机业务
3.  
   *
4.  
   * @return
5.  
   */
6.  
   @RequestMapping("/deductStock1")
7.  
   public String deductStock1() throws InterruptedException {
8.  
   /**
9.  
   * 单机下单操作
10.  
    * 存在的问题：
11.  
    * 并发量过大会存在超卖
12.  
    */
13.  
    //商品数量
14.  
    // int stock = Integer.parseInt(redisTemplate.opsForValue().get("stock"));
15.  
    // if (stock > 0) {
16.  
    // int resultStock = stock - 1;
17.  
    // redisTemplate.opsForValue().set("stock", resultStock "");
18.  
    // System.out.println("扣减成功，剩余库存：" resultStock);
19.  
    // } else {
20.  
    // System.out.println("扣减失败，库存不足！");
21.  
    // }
22.  
     
23.  
    /**
24.

25.  
    * 存在的问题：

27.  
    */
28.  
    synchronized (this) {
29.  
    int stock = Integer.parseInt(redisTemplate.opsForValue().get("stock"));
30.  
    if (stock > 0) {
31.  
    int resultStock = stock - 1;
32.  
    redisTemplate.opsForValue().set("stock", resultStock "");
33.  
    System.out.println("扣减成功，剩余库存：" resultStock);
34.  
    } else {
35.  
    System.out.println("扣减失败，库存不足！");
36.  
    }
37.  
    }
38.  
     
39.  
    /**

41.

43.  
    */
44.  
    // lock.lock();
45.  
    // try {
46.  
    // int stock = Integer.parseInt(redisTemplate.opsForValue().get("stock"));
47.  
    // if (stock > 0) {
48.  
    // int resultStock = stock - 1;
49.  
    // redisTemplate.opsForValue().set("stock", resultStock "");
50.  
    // System.out.println("扣减成功，剩余库存：" resultStock);
51.  
    // } else {
52.  
    // System.out.println("扣减失败，库存不足！");
53.  
    // }
54.  
    // } catch (Exception e) {
55.  
    // e.printStackTrace();
56.  
    // return "error";
57.  
    // } finally {
58.  
    // lock.unlock();
59.  
    // }
60.  
     
61.  
     
62.  
    return "success";
63.  
    }

 成功实现负载均衡效果

nginx命令

查看Nginx的版本号：nginx -V

启动Nginx：start nginx

快速停止或关闭Nginx：nginx -s stop

正常停止或关闭Nginx：nginx -s quit

配置文件修改重装载命令：nginx -s reload

查看windows任务管理器下Nginx的进程命令：tasklist /fi "imagename eq nginx.exe"
