Cant restart nginx and apache2

I am pretty new at this and have to do this for class. Please help

* Restarting nginx nginx [fail]

* Restarting web server apache2 (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down

The Apache error log may have more information.

How should I proceed next?

Thanks, I did what they suggested there for nginx. But apache2 is still giving me the same error.

prodip@ubuntu:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
prodip@ubuntu:~$ sudo fuser -k 80/tcp
80/tcp: 23484
prodip@ubuntu:~$ sudo kill -9 23484
prodip@ubuntu:~$ sudo fuser -k 80/tcp
prodip@ubuntu:~$ sudo service nginx restart
* Restarting nginx nginx [ OK ]

How did you install apache? How did you try to start it? Also, you only need one server. Trying to run both Apache and nginx at the same time could be causing problems.

I realize that's the problem. It is all part of tutorials at my linux class. In the previous tutorials, I was tasked to setup nginx. The current one wants me to run a apache2 server. I finally did a service nginx stop and was able to complete the tutorial.

Is "service service-name stop" a permanent process or do I have to run that command every time I start my system to stop either of apache or nginx?

It depends. If your servers start on boot, then yes, you would have to stop them every time. You can easily check the status of a service by running

sudo service <service-name> status

So for apache:

sudo service apache2 status
