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;upstream dx.exzel.co.nz { server 127.0.0.1:8080;}upstream mybusiness.exzel.co.nz { server 192.168.1.252:443;}server { listen 80; server_name dx.exzel.co.nz; rewrite ^(.*) https://dx.exzel.co.nz permanent;}server { listen 443; server_name dx.exzel.co.nz; ssl on; ssl_certificate /etc/letsencrypt/live/dx.exzel.co.nz/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/dx.exzel.co.nz/privkey.pem; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; access_log /var/log/nginx/ccieerror.log ; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://dx.exzel.co.nz; }}server { listen 80; server_name mybusiness.exzel.co.nz; rewrite ^(.*) https://mybusiness.exzel.co.nz permanent;}server { listen 443; server_name mybusiness.exzel.co.nz; ssl on; ssl_certificate /etc/letsencrypt/live/mybusiness.exzel.co.nz/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/mybusiness.exzel.co.nz/privkey.pem; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; access_log /var/log/nginx/mybusiness.log ; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass https://mybusiness.exzel.co.nz; }}server { listen 80; server_name www.empnz.co.nz empnz.co.nz; location / { proxy_pass http://192.168.1.15 ; } }}
