关于Nginx如何把nginx.conf配置文件解耦，拆成多个配置文件
前言随着nginx的使用，一台服务器下的域名及端口多了以后，在nginx.conf配置文件中就需要不断的配置server。
久而久之，就会发现nginx.conf特别臃肿。
所以我在这里对这个nginx.conf进行解耦拆分，让服务器上每个项目都有自己独立的子配置文件。
接下来的内容，可能会涉及到 主配置文件：nginx.config 子配置文件：nginx_xxx.config
配置nginx.配置主配置文件 nginx.config直接把新安装的Nginx里的原始nginx.config用下面代码替换掉。如果原始nginx.config中已经配置过server{ }，就需要提前备份好，改成子配置文件使用。

Java中如何通过经纬度坐标获取两个点之间的直线距离
前言现在很多App都需要附带着附近人列表功能，所以我在这里实现2个点之间的距离计算
经纬度的获取需要第三方来支持，高德地图、百度地图….附近人功能具体的实现逻辑：
获取每个人的经纬度坐标，存库记录
通过SQL获取指定距离范围内的用户列表（文章中的MySQL中通过经纬度，获取范围内的用户）
通过获取到的用户列表，计算自己与用户之间度距离（文章中的JAVA代码实现计算AB两点的直线距离）
方法一：JAVA代码实现计算AB两点的直线距离已知A、B两个点的经纬度，在代码中计算出直线距离
