raft python实现, 用于测试学习
Project description
说明
非拜占庭节点的分布式共识算法Raft的python实现。
Raft官网:https://raft.github.io/
raft
整体架构
文件说明
- node.py, log.py为raft核心代码
- node.py 实现raft的节点消息收发、角色转换等功能
- log.py 实现具体的日志存储
- rpc.py 实现具体消息编码和转发
- master.py 控制面中心节点, 进行group创建和管理
- slave.py 每个server上部署的控制面节点
test
环境:windows 10系统 单机
测试步骤
- 运行 python -m raft.master, 启动master节点
- 运行 python -m raft.slave, 启动slave节点
- 运行 python -m test.test_master param
- param: create_group, create一个raft group
- param: stop_group, 安全终止 一个raft group
- param: stop_master, 安全终止master
- 运行 python -m test.test_slave param
- param: stop_slave, 安全终止slave
- 运行 python -m test.client, 用户写入log
结果说明
- data/master, master存储的数据
- data/slvae, slave存储的数据
- data/node
- .log 各node交互过程监控数据, 可以在git bash中用tail -f filename.log查看
- persistent.json, node持久化数据
- log.json, 存储的日志
