Hallo liebe Leute,
vor Jahren habe ich mir meinen MM mit eurer Hilfe gebaut. Soweit alles gut und danke für euere Unterstützung. Da ich meinen MM nur selten nutze und ich mir LineageOS OHNE Google auf mein Handy installiert habe, wollte ich jetzt Nextcloud auf meinem RPI 3B+ installieren um dort meine Sicherungen abzulegen. Kann man Nextcloud und MM auf einen RPI betreiben? Es gibt hier eine gute Anleitung auf deutsch für die Installation von Nextcloud auf RPI. Hat das schonmal jemand gemacht ?

Gruß stoffel

i have test a lot with file attributes. not needed. magicMirror is not linux, its javascript. only the copy command and pm2 command in the exec function must linux conform. in the pm2 log you have sometimes error messages, but that comes from linux. so you have right, without x-flag its not executable, but MagicMirror ignore file attributes.

now i can cange all my configs with remote-control. for the moment i am finished this module. maybe later i have a new idea, ha,ha.

@sdetweil

ok, what can i say. i’v test it with other config und it works also. its overide the old config with the new config and restart mm.
i not understand why, but it works. realy

@sdetweil

ok, i am not a linux erpert. i think the exec command execute a script, and its work with this file-attributes. you can test it. maybe its read the file and exec the commands in it. i’v checked the attributes with filezilla, was 644, not executable but it works.

the file-attributes are for the security of RPI & MM importend. thats is for later.

at the moment ist works without errors. i can send you my files for test !?

@sdetweil

look at my first post, its a simple text-file with the extension .sh and its executable -rw-r–r–
the test.sh is not the problem, the file ist found and execute it. the problem was the cp command. but now i soved the problem.

cp -a -v ../MagicMirror/config/config.js ../MagicMirror/config/config_1.js 1>> ./log_erfolgreich.txt 2>> ./log_fehlgeschlagen.txt
pm2 restart all

i add the option -a . now its work !!
the log_erfolgreich.txt and log_fehlgeschlagen.txt are found in the MagicMirror dir, so cp starts at this dir.
the

../MagicMirror/

are needed, maybe mm starts from the .pm2 dir?!

i play around with it and other files (txt, png…)
i am lucky :-)
thanks very much for your help.

at WE i test your config-module and post it

@sdetweil

i’v test the exec command without bash… thats not work, i have a
/bin/sh: 1: …/MagicMirror/config/test.sh: Permission denied

with bash it works now, but the filename is a bit crazy

thats at ssh console. in filezilla the filename is correct but says no such file or directory

i have no idea what gos wrong

@sdetweil

fine, i will test it at WE.
Now its time to sleep. i test tomorrow with sh … and without bash/sh

hallo sdetweil,

have you finished your config-module :face_with_steam_from_nose: ?

the __dirname was from the beginning when i have a file not found error. now its found and i think the exec comand works, in log you can see after the error restart mm but i have no error message from then cp command. so i can not find whats the problem is. in the console.log i have no errors. where can i see error messages from the cp command.

hallo @ all ,

i am new here and german, so sorry for my english :-)

i build my first module. i started with this simple module.

it works. then i add an exec command

exec("bash ../MagicMirror/config/test.sh", (error, stdout, stderr) => {
	if (error) {
		console.error(`exec error: ${error}`)
		return;
	}

thats works ?! i am not sure.
the test.sh

cp ../MagicMirror/config/config.js ../MagicMirror/config/config_1.js
pm2 restart all

in my custom_menu.json i have an entry that send the notification TEST, my MMM_MeinModul.js recieved this and send

this.sendSocketNotification('START_TEST', {});

when my node_helper.js recieved this then call the function with the exec command.

the result is an error at pm2 log:

exec error: Error: Command failed: bash ../MagicMirror/config/test.sh

but thats not true. the pm2 restart all are executed and restart the mm.

so, i think the cp command not work, but i dont understand the problem.

here my module

Module.register("MMM-MeinModul",{
	defaults: {
		text: "Sergio"
	},

	getDom: function() {
		var wrapper = document.createElement("div");
		wrapper.innerHTML = this.config.text;
		return wrapper;
	},

	start: function() {
		this.sendSocketNotification('CONFIG', this.config);
	},

	socketNotificationReceived: function(notification, payload) {
		if (notification === 'STARTED') {
			console.log("MMM-MeinModule notification [" + notification + "] payload [" + payload + "]")
			this.config.text = 'Started';
			this.updateDom();
		}
	},
	
	notificationReceived: function(notification, payload) {
		if (notification === 'TEST') {
			console.log("MMM-MeinModule notification [" + notification + "] payload [" + payload + "]")
			this.config.text = 'changed';
			this.updateDom();
			this.sendSocketNotification('START_TEST', {});
		}
	}
});

and here my node_helper

var NodeHelper = require("node_helper");
const exec = require("child_process").exec;

module.exports = NodeHelper.create({
	start: function () {
		this.config = {}
	},
	
copyfile: function () {
console.log(__dirname)
exec("bash ../MagicMirror/config/test.sh", (error, stdout, stderr) => {
	if (error) {
		console.error(`exec error: ${error}`)
		return;
	}
});
},

	socketNotificationReceived: function (notification, payload) {
		if (notification === 'CONFIG') {
			this.config = payload;
			console.log("MMM-MeinModule node_helper (config) notification [" + notification + "] payload [" + payload + "]")
			this.sendSocketNotification('STARTED',payload);
		}
		if (notification === 'START_TEST') {
			console.log("MMM-MeinModule node_helper (TEST) notification [" + notification + "] payload [" + payload + "]")
			this.copyfile();
		}
	}
});

can sameone get a hint please ?

@sdetweil

thanks ;-)

and i like people like you who spent a lot of time for creating useful modules like this !!

again thanks a lot
