This causes app is slow, How to solve this problem, thanks very much
I don't know the port used by your application. It depends on your code. In this example, I will assume the port is 3000
.
You need to verify if the port is already took on your system. To do that:
sudo netstat -nltp | grep 3000
sudo lsof -i -P | grep 3000
If you have a result, you need to kill the process (kill <pid>
).
You should check if pm2 list
returns 0 process. In addition, when you do a pm2 stopAll
, the socket is not released. Don't forget to do a pm2 kill
to be sure the daemon is killed.
$ pm2 kill
Daemon killed
