nginx如何配置代理轉發

Nginx是個厲害的服務器，可以配置多個服務器，一個server就是一個服務器



server {

      listen       80;
      server_name  *.yourdomain.com;
   ....

}

代理轉發是在server下面的location進行配置



server {

   // 服務器配置

   location  / {

   // ...... 代理配置

   }

}

常見的Nginx代理配置




upstream my_server {                                                        

    server 10.0.0.2:8080;                                               

    keepalive 2000;

}

server {

    listen       80;                                                        

    server_name  10.0.0.1;                                              

    client_max_body_size 1024M;

 

    location /my/ {

        proxy_pass http://my_server/;

        proxy_set_header Host $host:$server_port;

    }

}

通過該配置，訪問nginx地址http://10.0.0.1:80/my的請求會被轉發到my_server服務地址http://10.0.0.2:8080/

需要注意的是，如果按照如下配置：




upstream my_server {                                                        

    server 10.0.0.2:8080;                                               

    keepalive 2000;

}

server {

    listen       80;                                                        

    server_name  10.0.0.1;                                              

    client_max_body_size 1024M;

 

    location /my/ {

        proxy_pass http://my_server;

        proxy_set_header Host $host:$server_port;

    }

}

那么，訪問nginx地址http://10.0.0.1:80/my的請求會被轉發到my_server服務地址http://10.0.0.2:8080/my。這是因為proxy_pass參數中如果不包含url的路徑，則會將location的pattern識別的路徑作為絕對路徑。
