problem with niginx: nginx[14701]: nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

  • 772

I am trying to install ph8. I had earlier php7.4 running under nginx. When I executed following command:

@lc2530hz:~$ journalctl -xe

Then I tried the following command:

$     sudo netstat -plant | grep 80

Somebody please guide me how to solve this problem.

@waltinator Hi, I am getting the same answer as above i.e. firsfox and nginx are sharing port 80.
