利用nginx反向代理功能将http网站改造成https

内网服务器10.0.0.4使用web应用是http，由于各种原因无法在10.0.0.4上将http升级至https

此时可以在另一台服务器10.0.0.3上部署nginx ,利用nginx的反向代理功能，将访问10.0.0.3的流量转发至10.0.0.4 同时将访问80端口的流量自动跳转至443

当然也可以在10.0.0.4这台服务器上部署nginx，但nginx监听的端口不能和原来的应用一样，需要换一个端口

nginx配置如下

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    server {
        listen 80;
        server_name example.com www.example.com;
        return 301 https://$host$request_uri;
    }
    server {
        listen       443 ssl;

        server_name  example.com www.example.com;
