Nginx反向代理多域名的HTTP和HTTPS服务

当前Nginx已经反向代理了两个网站，分别是基于Windows的IIS和Linux的Apach服务器，提供网页服务。

现在有新项目的网页需要对外提供服务，需要在代理服务器上增加另外一个网站，使用HTTPS访问以及HTTP自动跳转HTTPS。由于新网页是静态页面，所以使用Docker部署在Nginx代理服务器上。相关的certificates是通过let's encrypt来获取的，都是单独的证书，没有申请通配符形式的证书。

在Nginx代理端部署SSL证书即可，后端不需要部署SSL也可以实现HTTPS访问。

Nginx代理服务器配置：

worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
worker_connections  1024;
}

http {
include       /usr/local/nginx/conf/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"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
tcp_nopush      on;
tcp_nodelay     on;
