19.7. Peer 节点安装

19.7.1. 安装 Docker 镜像

			
docker pull hyperledger/fabric-peer:x86_64-1.1.0
docker tag hyperledger/fabric-peer:x86_64-1.1.0 hyperledger/fabric-peer
			
			

19.7.2. docker-compose-peer.yml

			
version: '3'

services:

  peer0.org1.example.com:
    container_name: peer0.org1.example.com
    image: hyperledger/fabric-peer
    environment:

      - CORE_PEER_ID=peer0.org1.example.com

      # The CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME and CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD

Peer 需要连接到 CouchDB 注意配置项 CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=172.16.0.17:5984

同时连接CouchDB的用户与密码要正确

19.7.3. 启动 Peer 节点

			
[root@localhost netkiller]# docker-compose -f docker-compose-peer.yaml up -d
			
			

19.7.4. 创建 Channel

进入 Peer 容器

			
docker-compose -f docker-compose-peer.yaml exec peer0.org1.example.com bash
			
			

添加 Orderer 节点并创建 Channel

			
CORE_PEER_LOCALMSPID=Org1MSP
CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp
peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx

peer channel create -o 172.16.0.17:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
			
			

加入到 mychannel

			
CORE_PEER_LOCALMSPID=Org1MSP
CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp
peer channel join -b mychannel.block
			
			

查看通道
