### 简介 ###

1.  nginx域名反向代理，整合http和https，同时实现iphash的负载均衡配置；
2.  本篇博客展示nginx的配置文件nginx.conf的详细配置；

### 实践 ###

#user  nobody;
    worker_processes  1; #lscpu修改成内核数
    
    events {
        worker_connections  1024;  #修改成：65535
    }

    #1. nginx默认接入端口为80；
    #2. 多少个域名配置则配置使用多少个server；
    #3. nginx接入https端口默认是443；
