本案例使用node-red 工具控制设备执行 linux 指令。请通过网线将设备千兆网口与 ETH1 和上位机连接至公网, 确保可正常访问互联网。 设备启动,执行 node-red 程序,将上位机登录到 node-red 部署系统。 为便于测试,我司提供的经验证的执行 linux 指令为案例 “ node-red\node_execute\command\ ”目录下的 co mm...
依次运行如下三条命令 cd node-v0.10.26-linux-x64/bin ls ./node -v 1. 2. 3. 因为/home/kun/mysofltware/node-v0.10.26-linux-x64/bin这个目录是不在环境变量中的,所以只能到该目录下才能node的程序。如果在其他的目录下执行node命令的话 ,必须通过绝对路径访问才可以的 如果要在任意目录可以访问的...
