A grid consists of a single central 'introducer and vdrive' node and a large
|
||||
number of 'client' nodes. If you are joining an existing grid, the

number of 'client' nodes. If you are joining an existing grid, the
|
||||
introducer-and-vdrive node will already be running, and you'll just need to
|
||||
create a client node. If you're creating a brand new grid, you'll need to
|
||||
create a client node. If you're creating a brand new grid, you'll need to
|
||||
create both an introducer-and-vdrive and a client (and then invite other
|
||||
people to create their own client nodes and join your grid).
|
||||
|
||||
The introducer (-and-vdrive) node is constructed by running 'allmydata-tahoe
|
||||
create-introducer --basedir $HERE'. Once constructed, you can start the
|
||||
create-introducer --basedir $HERE'. Once constructed, you can start the
|
||||
introducer by running 'allmydata-tahoe start --basedir $HERE' (or, if you
|
||||
are already in the introducer's base directory, just type 'allmydata-tahoe
|
||||
start'). Inside that base directory, there will be a pair of files
|
||||
'introducer.furl' and 'vdrive.furl'. Make a copy of these, as they'll be
|
||||
start'). Inside that base directory, there will be a pair of files
|
||||
'introducer.furl' and 'vdrive.furl'. Make a copy of these, as they'll be
|
||||
needed on the client nodes.
|
||||
|
||||
To construct a client node, pick a new working directory for it, then run
|
||||
'allmydata-tahoe create-client --basedir $HERE'. Copy the two .furl files
|
||||
'allmydata-tahoe create-client --basedir $HERE'. Copy the two .furl files
|
||||
from the introducer into this new directory, then run 'allmydata-tahoe start
|
||||
--basedir $HERE'. After that, the client node should be off and running. The
|
||||
first thing it will do is connect to the introducer and introduce itself to
|
||||
all other nodes on the grid. You can follow its progress by looking at the
|
||||
$HERE/twistd.log file.

|
||||
|
||||
To actually use the client, enable the web interface by writing a port
|
||||
number (like "8080") into a file named $HERE/webport and then restarting the
|
||||
node with 'allmydata-tahoe restart --basedir $HERE'. This will prompt the
|
||||
node with 'allmydata-tahoe restart --basedir $HERE'. This will prompt the
|
||||
client node to run a webserver on the desired port, through which you can
|
||||
view, upload, download, and delete files.
|
||||
|
||||
A client node directory can also be created without installing the code
|

first. Just use 'make create-client', and a new directory named 'CLIENTDIR'

will be created inside the top of the source tree. Copy the relevant .furl

To stop it again, use 'make stop-client'. Similar makefile targets exist for

making and running an introducer node.
