Fabric多机部署-e2e
测试环境为三台华为云ECS主机，加入在同一虚拟子网中；
实验将fabric/example/e2e_cli进行修改测试多机部署;
三个node上的fabric环境一致，需要修改e2e配置文件；
fabric v1.4已经移除e2e demo,本次版本为fabric v1.2。

启动前，生成初始块及相关证书
简化操作，注释掉三个node上network_setup.sh脚本的networkDown函数中删除证书和初始块的命令77 function networkDown () { 78 docker-compose -f $COMPOSE_FILE -f $COMPOSE_FILE_COUCH down 79 80 #Cleanup the chaincode containers 81 clearContainers 82 83 #Cleanup images 84 removeUnwantedImages 85 86 # remove orderer block and other channel configuration transactions and certs 87 #rm -rf channel-artifacts/*.block channel-artifacts/*.tx crypto-config 88 }./network_setup.sh启动，生成channel-artifacts、crypto-config两个文件，通过scp命令服务到node2、node3的e2e目录下 -
测试
启动demo,在三个node上启动脚本#node1 root@liu:~/work/go/src/github.com/hyperledger/fabric/examples/e2e_cli# ./network_setup.sh #node2 root@lhys:~/work/go/src/github.com/hyperledger/fabric/examples/e2e_cli# ./network_setup.sh #node3 [root@cce-demo1522483688765-00274 e2e_cli]# ./network_setup.sh观察node1的输出，正常结果如下所示

中间如果有其他异常，比如org2拒绝连接，背书失败等，可通过docker log 查看日志
-
测试过程中遇到的问题
- ip记错，导致org2 connect: connection refused
- 端口没改，因为e2e中peer均开方7051、7052、7053端口，为防止冲突，fabric进行了暴露了对应的外部端口如80** 90** 100**；
但peer内部访问仍是705*,单机下fabric进行了转发处理，多机下需要改回705*端口
-
总结
- 添加为orderer、org2、cli添加extra_hosts
- 修改org2的peer容器暴露的端口
- 生成创世块、证书，并复制到其他节点
