httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work.  See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make
# redirections work in a sensible way.
#
#ServerName exam.defaultdoman....:80

ServerName 127.0.0.1:80

잘 모르겠으면 위처럼 127.0.0.1:80 이라고 하셔도 됨.
