Getting Tahoe-LAFS
==================
Welcome to `the Tahoe-LAFS project`_, a secure, decentralized, fault-tolerant
storage system.

How To Get Tahoe-LAFS
=====================
This procedure has been verified to work on Windows, Mac, OpenSolaris, and
too many flavors of Linux and of BSD to list.

In some cases these instructions may fail due to peculiarities of your
platform.
If the following instructions don't Just Work without any further effort on
your part, then please write to `the tahoe-dev mailing list`_ where friendly
hackers will help you out.

Install Python
--------------
Check if you already have an adequate version of Python installed by running
2016-03-13 14:34:31 +00:00
``python -V``. The latest version of Python v2.7 is required. Python v2.6.x
and v3 do not work. On Windows, we recommend the use of native Python v2.7,
not Cygwin Python. If you don't have one of these versions of Python
installed, `download`_ and install the latest version of Python v2.7. Make
sure that the path to the installation directory has no spaces in it (e.g. on
Windows, do not install Python in the "Program Files" directory).

Download the latest stable release, `Tahoe-LAFS v1.10.2`_.

Set Up Tahoe-LAFS
-----------------
Unpack the zip file and cd into the top-level directory that is thus created.
Run "``python setup.py build``" to generate the ``tahoe`` executable in a
subdirectory of the current directory named ``bin``. This will download and
build anything you need from various websites.
On Windows, the ``build`` step might tell you to open a new Command Prompt
(or, on XP and earlier, to log out and back in again). This is needed the
first time you set up Tahoe-LAFS on a particular installation of Windows.
If you see an error like ``fatal error: Python.h: No such file or directory``
while compiling the dependencies, you need the Python development headers. If
you are on a Debian or Ubuntu system, you can install them with ``sudo
apt-get install python-dev``. On RedHat/Fedora, install ``python-devel``.
Run "``bin/tahoe --version``" (on Windows, "``bin\tahoe --version``") to
verify that the executable tool prints out the right version number after
2012-06-01 21:01:04 +00:00
"``allmydata-tahoe:``".
Optionally run "``python setup.py trial``" to verify that it passes all of
its self-tests.
Run Tahoe-LAFS
--------------
Now you are ready to deploy a decentralized filesystem. The ``tahoe``
executable in the ``bin`` directory can configure and launch your Tahoe-LAFS
nodes. See `<running.rst>`__ for instructions on how to do that.
