Nginx反向代理多域名的HTTP和HTTPS服務

當前Nginx已經反向代理了兩個網站，分別是基於Windows的IIS和Linux的Apach服務器，提供網頁服務。

如今有新項目的網頁須要對外提供服務，須要在代理服務器上增長另一個網站，使用HTTPS訪問以及HTTP自動跳轉HTTPS。因爲新網頁是靜態頁面，因此使用Docker部署在Nginx代理服務器上。相關的certificates是經過let's encrypt來獲取的，都是單獨的證書，沒有申請通配符形式的證書。

在Nginx代理端部署SSL證書便可，後端不須要部署SSL也能夠實現HTTPS訪問。

Nginx代理服務器配置：

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;
