Simple HTTP-based key-value store example

This example demonstrates how easily you can implement an HTTP-based in-memory distributed key value store using BRaft.

Usage

1. Build example:
   1. go install ./...
2. Run nodes locally:
   1. BRAFT_RPORT=15000 braft
   2. BRAFT_RPORT=16000 braft
   3. BRAFT_RPORT=17000 braft
3. Put value on any node:
   1. curl -X POST 'http://localhost:15002/kv?map=test&k=somekey&v=somevalue'
4. Get value from all the nodes:
   1. curl 'http://localhost:15002/kv?map=test&k=somekey'
   2. curl 'http://localhost:16002/kv?map=test&k=somekey'
   3. curl 'http://localhost:17002/kv?map=test&k=somekey'
5. Distribute some items gurl POST :15002/distribute

本机启动两个节点:

1. BRAFT_DISCOVERY=:15001,:16001 BRAFT_RPORT=15000 braft
2. BRAFT_DISCOVERY=:15001,:16001 BRAFT_RPORT=16000 braft

防火墙调整规则，模拟脑裂:

1. 从防火墙拒绝对端的访问: iptables -A INPUT -s 172.16.25.57 -j DROP
2. 查询规则: iptables -L -n --line-numbers
3. 删除规则: iptables -D INPUT 1
