You can kill all node processes using pkill node  or you can do a ps T to see all processes on this terminal then you can kill a specific process ID doing a kill  processID  example  kill 24491  Additionally  you can do a ps -help to see all the available options

If you want know  the how may nodejs processes running then you can use this command  ps -aef   grep node   So it will give list of nodejs process with it s project name  It will be helpful when you are running multipe nodejs application  amp  you want kill specific process for the specific project   Above command will give output like  XXX  12886  1741  1 12 36          00 00 05  home username  nvm versions node v9 2 0 bin node --inspect-brk 43443  node application running path    So to kill you can use following command  kill -9 12886   So it will kill the spcefic node process

If all those kill process commands don t work for you  my suggestion is to check if you were using any other packages to run your node process   I had the similar issue  and it was due to I was running my node process using PM2 a NPM package   The kill  processID  command disables the process but keeps the port occupied  Hence I had to go into PM2 and dump all node process to free up the port again
