| + | ===== Tiny Core Linux over HTTP ===== | ||
| + | This application note describes how [[http://tinycorelinux.com/|Tiny Core Linux]] can be HTTP-booted using the gPXE network bootloader. | ||
| + | |||
| + | ==== Overview ==== | ||
| + | Although Tiny Core Linux comes with PXE netboot support, HTTP booting is attractive because it is more flexible. Only a HTTP server is required (rather than a full DHCP + TFTP setup). HTTP also works well over the internet. | ||
| + | |||
| + | Tiny Core Linux is "the core needed to boot into a very minimal X desktop typically with wired internet access". From there you can load applications on-demand from the internet. It's a great starting point for a custom thin-client or for one-off Linux sessions without big downloads upfront. | ||
| + | |||
| + | ==== Preparing to HTTP boot ==== | ||
| + | Download the latest Tiny Core Linux ISO image: | ||
| + | |||
| + | wget http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/release/tinycore_1.2.iso | ||
| + | |||
| + | Mount the ISO: | ||
| + | |||
| + | mount -o loop tinycore_1.2.iso /mnt | ||
| + | |||
| + | Copy kernel and initramfs to a web-accessible directory: | ||
| + | |||
| + | cp /mnt/boot/{bzImage,tinycore.gz} /var/www | ||
| + | |||
| + | Create a gPXE script for easy booting: | ||
| + | |||
| + | cat >/var/www/tinycore.gpxe | ||
| + | #!gpxe | ||
| + | kernel http://example.org/bzImage | ||
| + | initrd http://example.org/tinycore.gz | ||
| + | boot | ||
| + | ^D | ||
| + | |||
| + | ==== Booting a client machine ==== | ||
| + | Boot gPXE and enter the following command at the shell (Ctrl+B): | ||
| + | |||
| + | dhcp net0 | ||
| + | chain http://example.org/tinycore.gpxe | ||
| + | |||
| + | Tiny Core Linux should download via HTTP and boot. | ||
| + | |||
| + | ==== Going further... ==== | ||
| + | You may want to add kernel command-line arguments like this in ''tinycore.gpxe'': | ||
| + | |||
| + | kernel http://example.org/bzImage lang=en kmap=us | ||
