-* Quick installation recipe
-
-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). For more elaborate installation
-instructions see [[#source-deployment][Source deployment]].
+an example of the [[#gn2-dependency-graph][GN2 Dependency Graph]].
-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.
+* Install
-** Step 1: Install GNU Guix
+The quickest way to install GN2 is by using a binary installation
+(tarball or Docker image). These installations are bundled by GNU
+Guix and include all dependencies. You can install GeneNetwork on most
+Linux distributions, including Debian, Ubuntu, Fedora and CentOS,
+provided you have administrator privileges (root). The alternative is
+a Docker installation.
-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').
+** Tarball
-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)
+Download the ~800Mb tarball from
+[[http://files.genenetwork.org/software/binary_tarball/]]. Validate the checksum and
+unpack to root, for example
-#+begin_src bash
-export PATH=~/.guix-profile/bin:$PATH
-guix pull
-guix package -i hello --dry-run
-#+end_src
-
-Which should show something like
+: tar xvzf genenetwork2-2.10rc3-1538ffd-tarball-pack.tar.gz
+: mv /gnu /
+: mv /opt/genenetwork2 /opt/
-: The following files would be downloaded:
-: /gnu/store/zby49aqfbd9w9br4l52mvb3y6f9vfv22-hello-2.10
-: ...
-#+end_src
+Now you shoud be able to start the server with
-means binary installs. The actual installation command of 'hello' is
+: /opt/genenetwork2/bin/genenetwork2
-#+begin_src bash
-guix package -i hello
-hello
- Hello, world!
-#+end_src
+When the server stops with a MySQL error [[#run-mysql-server][Run MySQL server]]
+and set SQL_URI to point at it. For example:
-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'. Press Ctrl-C to interrupt.
+: export SQL_URI=mysql://gn2:mysql_password@127.0.0.1/db_webqtl_s
-If you need more help we have another writeup in [[https://github.com/pjotrp/guix-notes/blob/master/INSTALL.org#binary-installation][guix-notes]]. To get
-rid of the locale warning see [[https://github.com/pjotrp/guix-notes/blob/master/INSTALL.org#set-locale][set-locale]].
+See also [[#mysql-cant-connect-server-through-socket-error][Mysql can't connect server through socket ERROR]].
-** Step 2: Checkout the GN2 git repositories
+** Docker
-To fixate the software dependency graph GN2 uses git repositories of
-Guix packages. First install git if it is missing
+Docker images are also available through
+[[http://files.genenetwork.org/software/]]. Validate the checksum and run
+with [[https://docs.docker.com/engine/reference/commandline/load/][Docker load]].
-#+begin_src bash
-guix package -i git
-export GIT_SSL_CAINFO=/etc/ssl/certs/ca-certificates.crt
-#+end_src
+** With source
-check out the git repositories (gn-deploy branch)
+For more elaborate installation instructions on deploying GeneNetwork from
+source see [[#source-deployment][Source deployment]].

-git clone --branch gn-deploy --recursive https://github.com/genenetwork/guix guix-gn-deploy
-cd guix-gn-deploy
-#+end_src bash
+* Running GN2
-To test whether this is working try:
+Default settings for GN2 are listed in a file called
+[[../etc/default_settings.py][default_settings.py]]. You can copy this file and pass it as a new
+parameter to the genenetwork2 command, e.g.
-#+begin_src bash
-#+end_src bash
+: genenetwork2 mysettings.py
+or you can set environment variables to override individual parameters, e.g.
-** Step 3: Authorize the GN Guix server
+: env SERVER_PORT=5004 SQL_URI=mysql://user:pwd@dbhostname/db_webqtl genenetwork2
-GN2 has its own GNU Guix binary distribution server. To trust it you have
-to add the following key

+developing GN2.
