nginx 二级域名转发

域名解析里正常解析80，在nginx里转发

server {
	listen 80;

	# SSL configuration
	#
	# listen 443 ssl default_server;
	# listen [::]:443 ssl default_server;
	#
	# Note: You should disable gzip for SSL traffic.
	# See: https://bugs.debian.org/773332

	server_name [在这填网站];

    location / {
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   Host      $http_host;
        proxy_pass         http://0.0.0.0:3000;
    }
}
