You are saying that /opt/www/cmi.certi.org.br/ is your apache server's document root. Verify please:
fgrep DocumentRoot /etc/httpd/conf/httpd.conf
Server could be setup for virtual apaches, so check this:
tail -n 50 /etc/httpd/conf/httpd.conf
Do you see anything like this?
<VirtualHost *:80>
ServerAdmin webmaster@sos.tcea.org
DocumentRoot /home/testsite/
ServerName testsite.tcea.org
ErrorLog logs/testsite_error_log
CustomLog logs/testsite_access_log common
# AllowOverride ALL
</VirtualHost>
