You don't have permission to access / on this server

Edit httpd.conf file, which is in /etc/httpd/conf/httpd.conf. Add the below code.

<Directory "/">
#Options FollowSymLinks
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride None
Allow from all
</Directory>

<Directory "/home/">
 #Options FollowSymLinks
 Options Indexes FollowSymLinks Includes ExecCGI
 AllowOverride None
 Allow from all
</Directory>

After the line no. 555 (in my case) . Check for the file permissions and restart the server.

service httpd restart   

Now, it will work . Still you are facing the same problem, disable the seLinux in /etc/selinux/config change SELINUX=disabled and restart the server as mentioned above and try it.

Hope this helps

Set SELinux in Permissive Mode using the command below:

setenforce 0;

Check file permissions of the /var/www/html and the ALLOW directive in your apache conf

Make sure all files are readable by the webserver and the allow directive is like

 <Directory "/var/www/html">
    Order allow,deny
    Allow from all
  </Directory>

if you can see files then consider sorting the directive to be more restrictive
