<h1>How To Run Tahoe</h1>
<p>This is how to run a Tahoe node or a complete Tahoe grid. First you
have to install the Tahoe source code, as documented in <a
href="install.html">install.html</a>.</p>
<p>The <cite>tahoe</cite> executable is used to create, start, and stop
nodes. Each node lives in a separate base directory, inside of which you
can add files to configure the node. Nodes also read and write files
within that directory.</p>
<p>A grid consists of a single Introducer and one or more nodes. If you
are creating a new grid, you'll need to create both an Introducer and a
node (and then invite other people to create their own nodes and join
your grid). If you are joining an existing grid (such as <a
href="http://allmydata.org/trac/tahoe/wiki/TestGrid">the public test
grid</a>), the Introducer will already be running, and you'll need to
create a node.</p>
<p>To construct an introducer, choose a new base directory for it (the
name of the directory is up to you). We'll call this directory $INTRODIR.
Now run <cite>tahoe create-introducer $INTRODIR</cite>, which will create
the directory for you. Now start the introducer by running <cite>tahoe
start $INTRODIR</cite>. After it starts, there will be a file named
<cite>introducer.furl</cite> in that base directory. This file contains
the URL which the nodes must use in order to connect to this
introducer.</p>
<p>To construct a node, choose a new empty base directory (again, the
name of the directory is up to you), which we'll call $NODEDIR. Now run
<cite>tahoe create-client $NODEDIR</cite>, which will create the
directory. Acquire a copy of the <cite>introducer.furl</cite> from the
introducer and put it into this directory, then run <cite>tahoe start
$NODEDIR</cite>. After that, the node should be off and running. The
first thing it will do is connect to the introducer and get itself
connected to all other nodes on the grid.</p>
<p>If you're only running a single node, the usual base directory for it
is ~/.tahoe . The <cite>tahoe</cite> executable will use this as a
default if you don't provide a $NODEDIR explicitly. So an easy way to set
up your node is to run <cite>tahoe create-client</cite>, copy in the
<cite>introducer.furl</cite>, then run <cite>tahoe start</cite>.</p>
<p>Point your web browser to <a
href="http://127.0.0.1:8123">http://127.0.0.1:8123</a> to use this
node.</p>
