Please help me in this trouble,

I use CentOS4.2 with Apache. For the future purpose, I create one Partition for storing data, I mounted it with one folder in (/) . but HTTPD cannot access (read/write) in this mounted folder.

Please, please help me

Did you set the permissions on the folder to give access to the user Apache runs as?

Do you have selinux enabled? If so, you can use the chcon command with the --reference=/var/www flag to fix it up. Then either reroll the directory/files in the directory or use chcon -R to fix up what's under it.

http://wiki.centos.org/HowTos/SELinux

Also, not related to selinux or your problem, but I move some of my data directories under a separate partition and then remount the dirs in fstab so the structure stays the same. Kinda like a symlink but more transparent. It also simplifies backups since I can just backup my /mnt/data directory for the most part.

example from my /etc/fstab file

/mnt/data/home      /home         none   rw,bind      0 0
/mnt/data/www      /var/www      none   rw,bind      0 0
/mnt/data/mysql      /var/lib/mysql      none   rw,bind      0 0

I tried to turn off SELinux, everythings come OK, thanks Bros very much.

Everything is OK until your box gets co-opted into a botnet
because your box gets owned because you turned SELinux off.

Go learn about SELinux and turn it back on.

BTW, the CentOS box you're talking about isn't a linode, is it?
