没有公网IP，花生壳+树莓派实现远程开发51单片机-2
~接上篇，继续分享操作6. 安装usb摄像头监控界面sudo apt-get install motion然后打开 motion daemon 守护进程，让他可以一直在后台运行：sudo nano /etc/default/motion＃no修改成yes:start_motion_daemon=yes修改motion的配置文件：sudo vim /etc/motion/motion.conf#deamon off 改成 ondeamon on#设置分辨率width 800height 600#关闭 localhost 的限制webcam_localhost off然后运行 motion：sudo motion现在我们的摄像头已经变成了一台网络摄像头。在chrome浏览器下访问 http://:8081 即可看到摄像头当前拍摄的画面。 7. 简单修改novnc界面在onvnc源码的app目录下面添加camera文件夹这里是jq的一个小插件实现了一个可以拖动的小框框链接：https://pan.baidu.com/s/1VZSh14pUXK36NcxrYTM1-A提取码：swk9最后修改vnc.html文件让我们把摄像头和远程界面合二为一<!DOCTYPE html><html lang="en" class="noVNC_loading"><head> <!-- noVNC example: simple example using default UI Copyright (C) 2019 The noVNC Authors noVNC is licensed under the MPL 2.0 (see LICENSE.txt) This file is licensed under the 2-Clause BSD license (see LICENSE.txt).

激活成功后，进入花生壳管理平台。
添加内网穿透映射时，点击页面上的“增加映射”按钮。根据页面提示填写映射所需的信息(10022端口）为例：
1：自定义；2：选择HTTP（因为我们要映射的部分都是网页）；3：选择用作互联网访问的域名；4：选择动态端口；5：树莓派设备的内网IP地址；6：映射的服务类型对应端口；确认映射内容无误后，点击“确定”。好了，完美实现远程开发51单片机，本次分享到这里！学习大家的耐心阅读。平时大家在工作学习中遇到没有公网IP情况下的远程访问时，都可以通过花生壳来进行内网穿透，像开发调试、游戏联机、NAS访问、FTP文件共享等，花生壳都可以实现。
花生壳有远程访问流量限制吧 不花钱只能一些小流量工作吧
