Apache can't start

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using Set the 'ServerName' directive globally to suppress this message

How I resolve?

Could it be Log4Shell vulnerability which is currently 10/10 for danger?

I don’t think so, because I think it’s a problem with the configurations.

ucomment the line
#ServerName www.example.com:80

Did you google that? Just searching the error code would give you dozens of detailed solutions to your problem.


With google the solution is with correct ServerName in the .conf files. For me the command “apachectl configtest”, helped me find an error in the configuration, I had basically uncommented a module that was conflicting.


i resolved comment a module that creates a conflict with another module.
