Instalare pe Debian<\/strong>
\nSe descarca si executa scriptul de instalare:<\/p>\n

curl -sL https:\/\/deb.nodesource.com\/setup_12.x > setup_12.x \nchmod +x setup_12.x\n.\/setup_12.x<\/pre>\n
Se instaleaza NodeJS:<\/p>\n
apt install -y nodejs<\/pre>\n
Verificarea versiunii si instalarea Node-RED:<\/p>\n
node -v\u00a0\napt install -y build-essential libssl-dev\nnpm install -g --unsafe-perm node-red<\/pre>\n
Node-RED porneste cu:<\/p>\n
node-red -v<\/pre>\n
Instalare pe Raspberry Pi<\/strong>
\nSe instaleaza Nodejs 16 apoi Node Red:<\/p>\n
curl -fsSL https:\/\/deb.nodesource.com\/setup_16.x | sudo -E bash -\napt install nodejs\nbash <(curl -sL https:\/\/raw.githubusercontent.com\/node-red\/linux-installers\/master\/deb\/update-nodejs-and-nodered)\nsystemctl enable nodered.service<\/pre>\n
Se reporneste sistemul.<\/p>\n
Node Red ca serviciu pe Debian<\/strong><\/p>\n
Se creeaza fisierul node-red.service<\/em>:<\/p>\n
nano \/etc\/systemd\/system\/node-red.service<\/pre>\n
Se introduce urmatorul continut:<\/p>\n
# This script work on any system using systemd as the init process.<\/em>
\n# It works on Debian\/Raspbian Jessie.<\/em>
\n# If you have Debian\/Rapbian Wheezy and want to use this script with systemd <\/em>
\n# follow the information here : https:\/\/wiki.debian.org\/systemd<\/em><\/p>\n
# To easily download, install and set at startup:<\/em>
\n# wget -O \/tmp\/download https:\/\/gist.github.com\/Belphemur\/3f6d3bf211b0e8a18d93\/download && sudo tar -zxf \/tmp\/download –strip-components 1 -C \/etc\/systemd\/system\/ && sudo systemctl –reload-daemon && sudo systemctl enable Node-RED<\/em><\/p>\n
# To consult the log : journalctl -u Node-RED<\/em>

Apoi:<\/p>\n
systemctl daemon-reload\nsystemctl enable node-red.service\nsystemctl start node-red.service<\/pre>\n

Securizarea Node Red<\/strong>
\nIn folderul unde este instalat Node Red se instaleaza node-red-admin<\/em>:<\/p>\n
cd ~\/.node-red\nnpm install -g node-red-admin<\/pre>\n
Se genereaza hash-ul parolei:<\/p>\n
node-red-admin hash-pw<\/pre>\n
Se introduce parola si se genereaza hash-ul care se copie si se introduce \u00een settings.js<\/em>:
\nSe deschide fisierul settings.js<\/em>:<\/p>\n
cd ~\nnano \/.node-red\/settings.js<\/pre>\n
In sectiunea Securing Node-RED se activeaza proprietatile adminAuth:<\/em>, https:<\/em> si requireHttps: true<\/em>.
\nIn campul adminAuth<\/em> se inlocuieste hash-ul parolei cu cel generat anterior cu node-red-admin<\/em>. Se pot crea si alti utilizatori cu hash-urile parolelor generate ca mai sus. Inregistrarile specifice fiecarui utilizator trebuie sa fie despartite cu virgula:<\/p>\n

Pentru securizarea paginii statice generate de Node Red se activeaza httpNodeAuth:<\/em> si httpStaticAuth:<\/em> unde se inlocuieste \u201euser\u201d<\/em> si hash-ul parolei utilizatorulu respectiv. \u00cen ambele campuri trebuie sa fie acelasi utilizator;<\/p>\n

Se salveaza fisierul settings.js<\/em> si se reporneste Node Red

Pentru tradfri trebuie instalate pachetele CoAP:<\/p>\n

Calea pentru CoAP va fi:
