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]]. Essentially, download and unpack the tar ball (which +creates directories in /gnu and /var/guix), add build users and group +(Guix builds software as unpriviliged users) and run the Guix daemon +after fixing the paths (also known as the 'profile'). + +Once you have succeeded, you have to [[https://github.com/pjotrp/guix-notes/blob/master/INSTALL.org#set-the-key][set the key]] (getting permission +to download binaries from the GNU server) and you should be able to +install the hello package using binary packages (no building) + +#+begin_src bash +export PATH=~/.guix-profile/bin:$PATH +guix pull +guix package -i hello --dry-run +#+end_src + +Which should show something like + +: The following files would be downloaded: +: /gnu/store/zby49aqfbd9w9br4l52mvb3y6f9vfv22-hello-2.10 +: ... +#+end_src + +means binary installs. The actual installation command of 'hello' is + +#+begin_src bash +guix package -i hello +hello + Hello, world! +#+end_src + +If you actually see things building it means that Guix is not yet +properly installed and up-to-date, i.e., the key is missing or you +need to do a 'guix pull'.
