A simple shell script to start / stop / restart chrooted nginx web server under CentOS / RHEL Linux. You must have Nginx web server setup in a chroot (jail) so that you can minimizes the damage done by a potential break-in by isolating the web server to a small section of the filesystem. You can also mount $jail/tmp as a separate filesystem (/images/tmpfile.bin) with the noexec,nosuid, nodev options under Linux like operating systems.
