Nginx 反向代理

真实应用

背景

一台阿里云 ECS，一个域名

需求

emotionl.fun 的二级域名分别指向服务器的两个服务

实现思路

使用 nginx 的 upstream 控制上游服务器，用 proxy_pass 进行反向代理

操作

1. 使用第一台 nginx 开启两个静态服务

   worker_processes 1;
   
   events {
       worker_connections 1024;
   }
   
   http {
       include mime.types;
       default_type application/octet-stream;
       sendfile on;
       keepalive_timeout 65;
       gzip on;
       gzip_min_length 1024;
       gzip_comp_level 2;
       gzip_types text/plain text/css application/x-javascript application/javascript application/xml;
       server {
           listen 4444;
           location / {
               alias test_website/site1/;
           }
           location = /50x.html {
               root html;
           }
           error_page 500 502 503 504  /50x.html;
       }
       server {
           listen 6666;
           location / {
               alias test_website/site2/;
           }
           location = /50x.html {
               root html;
           }
           error_page 500 502 503 504  /50x.html;
       }
   }
   

2. 使用第二台 nginx 开启反向代理

   worker_processes 1;
   
   events {
       worker_connections 1024;
   }
   
   http {
       include mime.types;
       default_type application/octet-stream;
       sendfile on;
       keepalive_timeout 65;
       upstream site1 {
           server 127.0.0.1:1234;
       }
       upstream site2 {
           server 127.0.0.1:2342;
       }
       server {
           listen 80;
           server_name site1.emotionl.fun;
           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://site1;
           }
           location = /50x.html {
               root html;
           }
           error_page 500 502 503 504  /50x.html;
       }
       server {
           listen 80;
           server_name site2.emotionl.fun;
           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://site2;
           }
           location = /50x.html {
               root html;
           }
           error_page 500 502 503 504  /50x.html;
       }
   }
