Error : listen EACCES 0.0.0.0:80 foreverjs

I have a nodejs program running with forever https://www.npmjs.com/package/forever since several months (on Ubuntu 16.04.2 LTS). I had no problems (I have node v6.11.1).
But I recently wanted to use a package called bottleneck and for some reasons (because of the async syntax error) I wanted to update my nodejs.
So I followed his tip updating nodejs on ubuntu 16.04 (issues are coming up), I've executed :

sudo npm install -g n
sudo n lts

I've noticed that my app has stopped in forever list. So run :

forever start -o out.log -e err.log app.js

But my app was still stopped in forever list and no app.js task running (checked with htop). I check err.log and I find this error message :

Error: listen EACCES 0.0.0.0:80

at Module.load (module.js:487:32)

I tried different versions but nothing. It still doesn't work. So I run sudo n 6.11.1 to be back in v6.11.1 and I uninstalled n. I searched and I found that it may be a privilege problem. Now I'm using nmv instead of n and it still doesn't work, my app is still blocked in forever list.

But I've noticed something very weird, when I run :

forever start -o out.log -e err.log app.js

my app is blocked in forever list and no app.js task running (checked with htop), however when I do this :

sudo forever start -o out.log -e err.log app.js

forever tells me that my app is blocked in forever list but I see my app.js task running.

It worked since several months but since I tried to update nodejs, forever doesn't work anymore.

Now how can I run my app with forever ?
Thank you in advance

Solution

  • I guess I had broken packages. I reinstall everything: npm, nodejs... I upgraded my nodejs following this : https://askubuntu.com/a/548776 so I typed 

    curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

    Now for some reasons I have to use forever with sudo so I type 

    sudo forever list

    to get the list and

    sudo forever start -o out.log -e err.log app.js

    to start my app with forever. In both case don't forget to use sudo else it's confusing. Hope it will help someone someday.
