Change 404 Page on Apache – Linux

Use the ErrorDocument directive in your conf file to set a custom error message.

The easiest way to do this:

1. Create a file with your custom error message. Save it in:
   vim /var/www/not_found.html
2.  Edit  vim /etc/apache2/httpd.conf :

   Find the line that says:
   #ErrorDocument 404 /not_found.html

   Remove the leading “#”.
   ErrorDocument 404 /not_found.html

   Save.

3.  Restart apache.
   /etc/init.d/apache2 restart

Done!
