    chcon -Rv --type=httpd_sys_rw_content_t /dir
    

    This may help,rather than turn off the selinux.

    Ok, I found the issue: selinux

    Here's the solution: http://kb.sp.parallels.com/en/11142

    In case the page goes down:

    Symptoms

    After you change the default directory to store website content (say, to "/home"), you are unable to access the content of subdomains and additional websites over the Web.

    Cause

    This problem occurs if SELinux works in "Enforcement" mode. In this mode, webroot directories for websites and subdomains inside them have different permissions, and your web server fails to access them. Run this command:

    # getenforce
    

    The output should be: Enforcing

    Resolution

    Disable SELinux support: Open the file /etc/selinux/config in any editor and find this row:

    SELINUX=<value>
    

    Change it to:

    SELINUX=disabled
    

    If you cannot find this file, open the file /boot/grub/grub.conf in any editor and add the parameter selinux=0 to the Grub Boot Loader:

    title SE-Linux Test System
    root (hd0,0)
    kernel /boot/vmlinuz-2.4.20-selinux-XXXXXXXXXX ro root=/dev/hda1 nousb selinux=0
    #initrd /boot/initrd-2.4.20-selinux-XXXXXXXXXX.img
    

    Reboot the server to apply the changes. If you do not want to reboot, run this command:

    # setenforce 0
