What is chroot?
Chroot provides an important security tool for your web server. Chroot means CHange ROOT. It causes the named directory to become the root directory, the starting point for path searches so a malicious program cannot get to the real root file system. The Apache process that serves requests cannot see or get to files outside of this new root directory. Because of this we need to copy required files into our new root directory structure. For example Perl will need to be copied.
