Nginx反向代理的设置方法

nginx反向代理有很多的不同方面的用处, 这里主要讲如何设置docker的反向代理, 把本地的docker环境映射到域名上去.

系统环境

docker + nginx + 公网IP + 域名

操作方法

首先在启动docker时, 把docker内部端口使用-p 外部端口:内部端口映射到服务器的网络环境中, 不用给当前的docker容器创建docker网络环境.
然后编写nginx配置文件, 我是用oneinstack可以直接创建nginx的conf配置并且自动生成免费的SSL证书, 操作简单.
删掉oninstack在nginx配置文件中生成的对图片和其他资源文件处理的location配置, 加入如下的反向代理语句:
```
location / {
     proxy_set_header  Host  $http_host;
     proxy_set_header  X-Real-IP  $remote_addr;
     proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_pass  http://127.0.0.1:6001; #自行修改为你需要的配置
 }
```
上面的配置可以把6001端口的服务代理到其他端口,我在使用过程中是代理到了80端口, 之后使用域名进行解析.
