Fabric 1.4.2 动态添加orderer节点

2019-08-18  本文已影响0人  黑焰_

本文演示如何在raft共识启动的fabric网络中动态添加orderer节点，fabric版本v1.4.2。
为方便实验，使用fabric-samples/first-network/脚本演示，且默认您有一定的fabric基础了解。

下载源码

git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples/first-network/
git checkout v1.4.2

修改配置

启动fabric网络

./byfn.sh up -o etcdraft -c mychannel -s couchdb -i 1.4.2

更新配置

docker exec -it cli bash

PS.官方文档还有最后一步我没有做，更新endpoint配置操作
