Re: [mosquitto-dev] How to create users using php or javascript in mosqu

[Srinivas Pokala <pokalasrinu@xxxxxxxxx>]

Hi,

If I implement mosquitto-auth(MySql), how to connect mqtt client, I mean what I give in username and passwords?

client.connect({userName : "srinivas",password : "123456",onSuccess:onConnect,onFailure:doFail});

Thanks

I've heard that using exec() in php could maybe unsafe, because you give the user access to your commandline. Especially when you use a variable like $userName in your command.

If you want a more secure implementation I recommend the mosquitto-auth-plugin (see: https://github.com/jpmens/mosquitto-auth-plug). It saves your users in MySQL or other supported databases, so you have a more dynamically access to it.

Hi,

I use this code:

$userName = "srinivas";
$RndPsw  = "123456";
try{
    $command = "mosquitto_passwd -c /etc/mosquitto/passwd ".$userName." ".
$RndPsw ;
    exec($command , $out );
    print_r($out);
}catch(Exception $e){
    echo $e;
}
but not working getting empty response and user not created

when i execute only this command = "mosquitto_passwd -c
/etc/mosquitto/passwd ".$userName, getting response

Array ( [0] => Password: )

You probably have to add the -b option.

man mosquitto_passwd

   -b   Run in batch mode. This allows the password to be
provided at the command line which can be convenient but should
be used with care because the password will be visible on the
command line and in command history.

help me

Thanks
