apache2, raspberry pi 4 won't start?

Question

Apache HTTP Server

Hi hubr! Faced a problem. I decided to install Apache2 on Raspberry, but the problem is, "Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message"

Tried all the options from the Internet.

1) There is no httpd.conf file
2) After editing the apache2.conf file, namely adding ServerName localhost - the error did not go away

, what could be the problem?

Process: 23778 ExecStart=/usr/sbin/apachectl start (code=exited, status=1/FAILURE)

Answer 1

your server cannot bind the socket and not ServerName

Answer 2

I managed to start Apache2, while turning off Nginx. The second question arises, how to run Nginx?
