There is a file called
/etc/httpd/conf directory. Uncomment the following:
CustomLog logs/localhost-access_log common
NameVirtualHost enables Name Virtual Hosting. The section for
ServerAdmin is a contact email address.
DocumentRoot is where your www files are located for this vhost.
ServerName is useful for subdomains and such, but I generally use it to name the domain/subdomain/site.
CustomLog directives are usually per vhost, so that they aren't all logged into the same error/custom log, however, these are going to be where your error and access logs will be stored and written to - make sure the directory/file can be written by the apache user.
