Sorry, I'm a Noob. My VM's were stopped on GCP. I managed to get 1 VM up and running no problem by restarting it. I have tried to restart the other 2 VM's and they appear to be running but I've got no webpage. The external IP addresses are correct and the same at Google Domains, but still nothing.

Am I missing something in the backend of GCP? I've tried to SSH to restart Apache using this code:

sudo /opt/bitnami/ctlscript.sh restart apache

But I am getting this code back from the VM.

  Unmonitored apache
  Syntax OK
  /opt/bitnami/apache2/scripts/ctl.sh : apache not running
  Syntax OK
  (98)Address already in use: AH00073: make_sock: unable to listen for connections on address [::]:80
  (98)Address already in use: AH00073: make_sock: unable to listen for connections on address
  no listening sockets available, shutting down
  AH00015: Unable to open logs
  /opt/bitnami/apache2/scripts/ctl.sh : httpd could not be started
  Monitored apache

Is this an easy fix or do I need to start afresh from a snapshot in a new VM instance? Some help would be appreciated, please.


You have another process already listening on port 80. It could be anoher web server like nginx or a reverse proxy for example.

Try to use :

fuser -n tcp 80

to get the PID of the process listening on port 80.

  • Hi Yann, Many thanks for getting back to me. I tried that and this is the result I got: james@wordpress-1-vm:~$ fuser -n tcp 80 -bash: fuser: command not found james@wordpress-1-vm:~$ – James Sullivan Oct 19 '19 at 8:52
  • Unfortunately there is no fuser on that linux distribution. If you inspect ps auxww you should be able to figure out what process is using port 80. – Yann Bizeul Oct 19 '19 at 19:31
