1、原来的80端口改掉，下面配置：

server {        listen       80;        server_name  *.pobohn.com;        location / {            proxy_pass http://localhost:8081;            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       80;        server_name  *.daixinet.com;        location / {            proxy_pass http://localhost:8080;            proxy_set_header Host $host;            proxy_set_header X-Real-IP $remote_addr;            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;        }    }
