多域名nginx配置

Question

我刚刚安装了nginx，并且有多个域名指向同一个IP。当调用每个域时，我必须重定向到在同一台机器上运行的不同应用程序，每个应用程序都在不同的端口上运行。

至于ex，我有app1.domain.com，app2.domain.com & app3.domain.com

因此，对于app1.domain.com，我同样必须重定向到localhost:<port1>，对于app2.domain.com，我必须重定向到localhost:<port2>，而对于app3.domain.com，我必须重定向到localhost:<port3>

我该怎么走呢？

提前感谢

如果您的应用程序在不同的端口上运行，那么您的nginx conf文件应该如下所示。

upstream app1  {
      server 127.0.0.1:port1; #App1
}

upstream app2  {
      server 127.0.0.1:port2; #app2
}

server {
    listen       xxx.xxx.xxx.xxx:80;
    server_name  app1.domain.com;

    access_log  /var/log/nginx/log/app1.domain.com.access.log  main;
    error_log  /var/log/nginx/log/app1.domain.com.error.log;
    root   /usr/share/nginx/html;
    index  index.html index.htm;

    ## send request back to apache1 ##
    location / {
    proxy_pass  http://app1;
    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    proxy_redirect off;
    proxy_buffering off;
    proxy_set_header        Host            $host;
    proxy_set_header        X-Real-IP       $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
   }
}

server {
   listen      xxx.xxx.xxx.xxx:80;
   server_name app2.domain.com;
   access_log  /var/log/nginx/log/app2.domain.com.access.log  main;
   error_log   /var/log/nginx/log/app2.domain.com.error.log;
   root        /usr/local/nginx/html;
   index       index.html;

   location / {
        proxy_pass  http://app2;
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503         http_504;
        proxy_redirect off;
        proxy_buffering off;
        proxy_set_header        Host            app2.domain.com;
        proxy_set_header        X-Real-IP       $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

如果您有任何疑问，请告诉我。谢谢
