In this document we explain the GeneNetwork deployment system which is based on GNU Guix -(see Pjotr's [[https://github.com/pjotrp/guix-notes/blob/master/README.md][Guix-notes]]). +(see Pjotr's [[https://github.com/pjotrp/guix-notes/blob/master/README.md][Guix-notes]] and the main [[README.org]] doc). -* Binary deployment +* Binary deployment through GNU Guix +** Quick installation recipe -NYA (will go to README) +This is a recipe for quick and dirty installation of GN2. For +convenience everything is installed as root, though in reality only +GNU Guix has to be installed as root. I tested this recipe on a fresh +install of Debian 8.3.0 (in KVM) though it should work on any modern +Linux distribution (including CentOS). + + +Note that GN2 consists of an approx. 5 GB installation including +database. If you use a virtual machine we recommend to use at least +double. + +** Step 1: Install GNU Guix + +Fetch the GNU Guix binary from [[https://www.gnu.org/software/guix/download/][here]] (middle panel) and follow +[[https://www.gnu.org/software/guix/manual/html_node/Binary-Installation.html][instructions]].
