一、场景：
系统移动端需要映射到公网，但是后端地址不能映射出去
qbpm.xxxx.cn 系统解析内网IP
qmbpm.xxxx.cn 移动端解析公网IP
二、思路：
移动端前端公网端口放出80 443端口
移动端后端映射到内网后端地址qbpm.xxxx.cn:8443
三、解决方法：
vim nginx.conf
server {listen 80;listen 443 ssl;server_name qbpm.xxxx.cn;ssl_certificate /etc/nginx/cert/server.crt;ssl_certificate_key /etc/nginx/cert/server.key;ssl_session_cache shared:SSL:1m;ssl_session_timeout 5m;ssl_ciphers HIGH:!aNULL:!MD5;ssl_prefer_server_ciphers on;location / {root /etc/nginx/flowhtml;try_files $uri $uri/ /index.html;index index.html index.htm;}location ^~/prod-api/ {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass https://qbpm.xxxx.cn:8443/;} }server {listen 80;listen 443 ssl;server_name qmbpm.xxxx.cn;ssl_certificate /etc/nginx/cert/server.crt;ssl_certificate_key /etc/nginx/cert/server.key;ssl_session_cache shared:SSL:1m;ssl_session_timeout 5m;ssl_ciphers HIGH:!aNULL:!MD5;ssl_prefer_server_ciphers on;location / {root /etc/nginx/mflowhtml;try_files $uri $uri/ /index.html;index index.html index.htm;}location ^~/prod-api/ {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass https://qbpm.xxxx.cn:8443/;}}
