From a3a3f3f96f219da30d1baa74ca8e4512e5e3cc52 Mon Sep 17 00:00:00 2001 From: Brian Warner Date: Wed, 28 Mar 2007 10:48:29 -0700 Subject: [PATCH] added a README explaining how to get started and what library dependencies are needed --- README | 64 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 README diff --git a/README b/README new file mode 100644 index 00000000..00fd1da4 --- /dev/null +++ b/README @@ -0,0 +1,64 @@ + +Welcome to the AllMyData "tahoe" project. This project implements a +scalable distributed fault-tolerant filestore. + +The main application code is in the 'allmydata' package, under src/allmydata/ +. There is also a patched version of PyCrypto (adding a faster CTR-mode) in +src/Crypto/ which gets installed to the 'allmydata.Crypto' package (since the +API is different than the normal Crypto package). It also includes Zooko's +PyFEC library, a fast python wrapper around the Rizzo 'fec' C library, +installed to the 'pyfec' package and located in src/pyfec/ . + +DEPENDENCIES: + + Python 2.4 or newer (tested against both 2.4 and 2.5) + http://python.org/ + Twisted (probably 2.4.0 or newer) (subpackages 'core', 'web' + http://twistedmatrix.com/ + You'll want the following subpackages: core, web, trial, conch. + Note that Twisted requires zope.interface, and that the standard + batteries-included Twisted distribution includes a copy. + Foolscap (probably 0.0.7 or newer) + - note: since the Foolscap wire protocol is not yet compatible from one + release to the next, make sure all of your nodes are using the same + version of Foolscap + http://twistedmatrix.com/trac/wiki/FoolsCap + Nevow (probably 0.9.0 or later) + http://divmod.org/trac/wiki/DivmodNevow + +BUILDING: + + Just type 'make'. If the desired version of 'python' is not already on your + $PATH, then type 'make PYTHON=/path/to/your/preferred/python'. + + 'make test' runs the unit test suite. + + 'make deb-dapper' or 'make deb-sid' will construct a debian package named + 'allmydata-tahoe'. + +RUNNING: + + The installed package creates an 'allmydata-tahoe' executable, usually in + /usr/bin . This tool is used to create, start, and stop nodes. + + Somewhere in your mesh there must be a central 'queen' node. This is + constructed by running 'allmydata-tahoe create-queen --basedir WHERE'. Once + constructed, you can start the queen by running 'allmydata-tahoe start + --basedir WHERE'. 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 + from the queen 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 queen and introduce itself to all + other nodes on the mesh. 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 + client node to run a webserver on the desired port, through which you can + view, upload, download, and delete files. + -- 2.45.2
