Starting a new Tahoe-LAFS Grid on CentOS 6.5

For my purposes I want to remove any potential bottlenecks, so I've created a ramdisk to store my files. In a production environment you surely would want to point this at a disk.

create ramdisk basedir for testing (as root)

mkdir /mnt/ramdisk
mount -t tmpfs -o size=2g tmpfs /mnt/ramdisk
chown username: /mnt/ramdisk/

create & start the introducer

cd /mnt/ramdisk
tahoe create-introducer introducer
tahoe start introducer

create a node

mkdir /mnt/ramdisk/node
tahoe create-node --basedir /mnt/ramdisk/node

copy the introducer furl to the client

cd /mnt/ramdisk/introducer/private
cat introducer.furl
<copy pasted string into node/tahoe.cfg>

start the node

tahoe start --basedir /mnt/ramdisk/node

(misc) moving the venv around and starting nodes

move the virtualenv over

tar -cvzf tahoe-venv.tar.gz tahoe/
scp r- tahoe-venv.tar.gz node2:~/.
ssh node2
tar -xvzf tahoe-venv.tar.gz
source tahoe/bin/activate

create the ramdisk again (as root)

mkdir /mnt/ramdisk
mount -t tmpfs -o size=2g tmpfs /mnt/ramdisk
chown username: /mnt/ramdisk/

creating a second node

mkdir /mnt/ramdisk/node
tahoe create-node --basedir /mnt/ramdisk/node

As before, copy the introducer furl into node/tahoe.cfg and then

tahoe start --basedir /mnt/ramdisk/node
