第七节:Nginx限流和负载均衡、页面cdn、IIS部署优化、后续计划

一. Nginx限流和负载均衡

1. 限流

 可以ip限流或者限制总请求数。防止大量恶意请求,通过nginx的ip限制处理 1秒1个ip只能请求一次,但也有弊端,比如多个人在同一个ip下,容易误杀,所以看怎么取舍了.

参考代码:

#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;
}

    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"';

2. 负载均衡

  参考:https://www.cnblogs.com/yaopengfei/p/12499588.html

 

 

   在后续微服务章节中详细剖析测试。

 

二. 页面cdn 、IIS部署

 

  采用前后端分离的模式,前端页面可以单独部署cdn,或者一些秒伤详情页面可以做成纯静态页面,放到SSD硬盘上,从而减少了DB查询。

  该模块都在后续的微服务章节进行详细剖析和测试。

   

 

 

三. 后续计划

 

  单体架构下,主要是围绕下单业务,提供了一些思路,一些常规业务并没有实现,在后续的微服务章节,会完善常规业务。

  微服务架构涉及到的组件比较多,接下来一段时间将逐渐完善微服务的搭建,选择最适合的框架组装方式,不单单局限于.Net,组合测试到一定程度,回来完善微服务模块的博客。
