多个域名访问同一个nginx，根据域名不同，访问不同的项目

server {
    listen 80;
    server_name example.com;

   
 location / {
        root  /usr/share/nginx/html/research;
        index index.html index.htm;
    }
}

server {
    listen 80;
    server_name anotherdomain.com;

    location / {
        proxy_pass http://localhost:8082;  # 代理到第二个项目的地址和端口
    }
}
