我正在尝试将Nginx配置为LAN上多个服务器的反向代理.他们应该在我的WAN上使用不同的子域.我的配置如下所示：

@ReverseProxy:/etc/Nginx/sites-enabled$cat reverseproxy 
server { 
  server_name DOMAIN.eu;
  # app1 reverse proxy follow
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_pass http://10.0.2.5:80;
}
server { 
  server_name Subdomain.domain.eu;
  # app2 reverse proxy settings follow
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_pass http://10.0.2.33:80;
}

但我收到这个错误,无法进一步……

@ReverseProxy:/etc/Nginx/sites-enabled$Nginx -t
Nginx: [alert] could not open error log file: open() "/var/log/Nginx/error.log" Failed (13: Permission denied)
