node.js - Run linux command without password that need root permission -


i'm using node execute bash command on linux. need stop , start apache server. bash need type: 

sudo service apache2 stop

and need insert password. change modify 'visudo' after modification not asking password when run node error 

error: command failed: /bin/sh -c sudo systemctl status apache2.service sudo: no tty present , no askpass program specified

where problem? node code looks that

app.get('/statustest', function(req, res){     exec("sudo systemctl status apache2.service", function(err, stdout){         if(err) throw err;         console.log(stdout);         res.render('statustest');    }); })

you can try command automatic password input:

exec(`echo 'your_sudo_password' | sudo -s systemctl status apache2.service`, ...);
