nginx二级域名代理

二级域名带ssl证书代理

在nginx配置文件，增加代理配置服务

    server {
        listen 443 ssl;   #SSL协议访问端口号为443。此处如未添加ssl，可能会造成Nginx无法启动。
        server_name api.dshvv.com;  #二级域名。
        root html;
        index index.html index.htm;
        ssl_certificate /home/ssl/dshvv.pem;   #将domain name.pem替换成您证书的文件名。
        ssl_certificate_key /home/ssl/dshvv.key;   #将domain name.key替换成您证书的密钥文件名。
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;  #使用此加密套件。
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;   #使用该协议进行配置。
        ssl_prefer_server_ciphers on;   
        
        location / {
             proxy_pass http://127.0.0.1:7777; #代理地址
              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_set_header X-Forwarded-Proto $scheme;
              proxy_set_header X-Forwarded-Port $server_port;
        }
    }

意思是 遇到api.dshvv.com请求的时候，将代理至本地的7777服务。

需要注意的是，需要在域名服务上，开启二级域名的解析

 

 

 

普通二级域名配置

因为ssl证书是针对以及域名的，二级域名提示无效风险，但是不影响使用，也就是说二级域名用https请求会提示ssl证书无效
阿里有统配子域名的证书，但是要花钱，每年1-2k，还是算了。但是我们可以分别声情，这是免费的
如果二级域名不配置证书，代理可以做如下新增

server {
        listen 80;
        server_name api.dshvv.com;  #二级域名。
        root html;
        index index.html index.htm;
        
        location / {
             proxy_pass http://127.0.0.1:7777; #代理地址
              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_set_header X-Forwarded-Proto $scheme;
              proxy_set_header X-Forwarded-Port $server_port;
        }
    }

当然最好还是都加上，两种配置都写上，这样使用的时候有的选择

 

最优方案

1、配置两个域名证书

2、同时支持http和https

一下是最终的配置文件

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
