raft

raft implements the Raft distributed consensus algorithm.

Quickstart

The Raft cluster consists of 3 servers. To start each server, run the following commands in three separate terminal windows. A numbered prompt indicates the server is running, with the current role of the server by prompt color - red for follower, yellow for candidate and green for leader.

For server 1:

> python src/raftserver.py 1

1 >

For server 2:

> python src/raftserver.py 2

2 >

For server 3:

> python src/raftserver.py 3

3 >

To start the client, run the following command in a new terminal window.

> python src/raftclient.py 0

0 >

The append command instructs the server to append entries to its log. The command needs to be prefixed by the server number. For example, to instruct server 1 to append entries a, b and c to its log:

0 > 1 append a b c

To instruct all servers to expose its state:

0 > self
