继续折腾，当前这个工控机已经成为twincat runtime了，，接下来折腾node-red以及fuxa。目前在这个工控机上安装的软件来自不同的软件仓库：
从底层到上层，形成了三层软件生态：
Linux系统层（Debian） → 工业控制层（Beckhoff） → 应用生态层（npm）。
这也是工业PC相比传统PLC的一个变化：除了实时控制能力之外，还可以借助Linux生态扩展更多边缘计算和数据应用功能。
开始，相比TwinCAT Runtime安装时需要配置倍福软件仓库认证，Node-RED和FUXA属于Node.js开源生态软件，通常可以直接通过npm软件仓库获取。
1、检查Node.js环境
看看是否安装了
没有安装
-bash: node: command not found
2、配置npm软件源
测试npm仓库访问，输出可以访问
Administrator@BTN-000t12m0:~$ curl -I https://registry.npmjs.orgHTTP/2 200
3、准备Node.js运行环境

4、安装npm软件包管理工具
Node.js安装完成后，还需要安装npm（Node Package Manager），后续安装的Node-RED和FUXA，都将通过npm软件仓库获取和管理。
有一点很有趣，执行npm安装前，系统使用的仍然是前面配置好的Debian软件源，deb-mirror.beckhoff.com/debian，通过这个软件源，apt可以找到npm及其相关依赖。
npm安装完了，看看软件源
Administrator@BTN-000t12m0:~$ npm config get registryhttps://registry.npmjs.org/
Node.js和npm分别来自两个不同的软件生态：Node.js/npm工具本身通过Debian apt安装，而后续Node-RED、FUXA等应用则通过npm仓库获取。
5、通过npm安装Node-RED
安装过程中出现版本警告了，我选择了忽视，结束后检查发现不支持。
没办法，只能------卸载V20、换源、再安装V22
卸载
sudo apt remove nodejs npm
换源
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
再次安装，这回对了。
sudo apt install nodejs -y
试试启动一下，再用另外pc的浏览器访问一下 192.168.3.118:1880
启动了，掉坑里了，浏览器无法访问，---省略1000字---，最后确认是防火墙规则，得加个白名单，加上1880，顺便把1881 1883也加上。

安装FUXA
安装完成，浏览器可以访问。说一下踩了哪几个坑。
测试、测试而已。当前都是ssh登录启动服务项的，以后再配置成上电自动运行吧。框架有了，过两天往里面填写的东西，再看看资源消耗。
