If after installing Apache and starting the server the following message shows in the error logs and the apache server does not start:
hostname nor servname provided, or not known: mod_unique_id: unable to find IPv4 address of xxxxxx
then in httpd.conf disable the line
LoadModule unique_id_module libexec/apache2/mod_unique_id.so
Restart again. This is usually the fix if changing hosts and httpd.conf ServerName entries etc. do not fix the problem.
