-- Save & Quit (:wq)

# vi /etc/httpd/conf.d/10.100.97.38.conf

<VirtualHost *:80>

  # Admin email, Server Name (domain name) and any aliases
  ServerAdmin techsupport@domain.com
  ServerName 10.100.97.38


  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.php
  DocumentRoot /var/www/html


  # Custom log file locations
  LogLevel warn
  ErrorLog  /logs/10.100.97.38-error_log
  SetEnvIf Request_URI "\.(jpg|xml|png|gif|ico|js|css|swf|js?.|css?.)$" DontLog
  CustomLog /logs/10.100.97.38-access_log combined Env=!DontLog

</VirtualHost>

-- Save & Quit (:wq)

# vi /etc/httpd/conf.d/mysite.domain.com.conf
