vim /etc/httpd/conf.d/cacti.conf (configure)

[cesar]

Hello friends, you can help me with this topic, I go to my browser and I put http: // MY-IP-HERE / cacti / and then it tells me the following message:
Forbidden
You do not have permission to access / cacti on this server.
Editing the file
vim /etc/httpd/conf.d/cacti.conf
and changed the following:
Alias ​​/ cacti / usr / share / cacti
<Directory / usr / share / cacti />
<IfModule mod_authz_core.c>
# httpd 2.4
Requires all granted
</ IfModule>
<IfModule! Mod_authz_core.c>
# httpd 2.2
Order Deny, Allow
Deny from all
Allow from all
</ IfModule>
</ Directory>
<Directory / usr / share / cacti / install>

In spite of everything I still do not manage to enter to continue with the installation of cacti.
