Fabric2.0 SDK测试网络搭建运维weixin43839871的博客-

前期准备

  操作系统:CentOS 7
  Fabric版本: 2.x(1.x版本参考Fabric SDK测试网络搭建(v1.x))

   下载fabric-samples源码:下载地址

git clone -b master https://github.com/hyperledger/fabric-samples.git && cd fabric-samples && git checkout v2.0.1 mkdir bin  

   将下载好的二进制工具,放置在fabric-samples/bin路径下,请确保所下载二进制工具版本为v2.0.1

运行

   默认fabric-samples/first-network会启动一个两个组织四个节点(不含CA节点)的网络,和1.x版本的脚本不同,2.x版本脚本启动时可选择是否启动CA节点(默认不启动CA)
   byfn.sh脚本部分内容

# Generate the needed certificates, the genesis block and start the network. function networkUp() { #检查二进制文件是否可用,以及对应版本的docker镜像是否存在   checkPrereqs   # generate artifacts if they don't exist,假设当前sh所在的父目录不存在crypto-config目录就执行生成区块通道以及证书脚本 if [ ! -d "crypto-config" ]; then     generateCerts     generateChannelArtifacts   fi   COMPOSE_FILES="-f ${COMPOSE_FILE} -f ${COMPOSE_FILE_RAFT2}" if [ "${CERTIFICATE_AUTHORITIES}" == "true" ]; then     COMPOSE_FILES="${COMPOSE_FILES} -f ${COMPOSE_FILE_CA}" export BYFN_CA1_PRIVATE_KEY=$(cd crypto-config/peerOrganizations/org1.example.com/ca && ls *_sk) export BYFN_CA2_PRIVATE_KEY=$(cd crypto-config/peerOrganizations/org2.example.com/ca && ls *_sk) fi if [ "${IF_COUCHDB}" == "couchdb" ]; then     COMPOSE_FILES="${COMPOSE_FILES} -f ${COMPOSE_FILE_COUCH}" fi #使用docker-compose命令启动fabric网络   IMAGE_TAG=$IMAGETAG docker-compose ${COMPOSE_FILES} up -d 2>&1   docker ps -a   if [ $? -ne 0 ]; then echo "ERROR !!!! Unable to start network" exit 1   fi echo "Sleeping 15s to allow Raft cluster to complete booting" sleep 15    if [ "${NO_CHAINCODE}" != "true" ]; then #加载go合约依赖包 echo Vendoring Go dependencies ...     pushd ../chaincode/abstore/go     GO111MODULE=on go mod vendor     popd echo Finished vendoring Go dependencies   fi # now run the end to end script # 使用cli客户端执行脚本操作   docker exec cli scripts/script.sh $CHANNEL_NAME $CLI_DELAY $CC_SRC_LANGUAGE $CLI_TIMEOUT $VERBOSE $NO_CHAINCODE if [ $? -ne 0 ]; then echo "ERROR !!!! Test failed" exit 1   fi } 

  CERTIFICATE_AUTHORITIES为一变量,启动时通过-a参数传入;进入fabric-samples/first-network/目录,看下官方还提供了哪些命令

./byfn.sh help 

输出:

Usage:    byfn.sh <mode> [-c <channel name>] [-t <timeout>] [-d <delay>] [-f <docker-compose-file>] [-s <dbtype>] [-l <language>] [-o <consensus-type>] [-i <imagetag>] [-a] [-n] [-v] <mode> - one of 'up', 'down', 'restart', 'generate' or 'upgrade'       - 'up' - bring up the network with docker-compose up       - 'down' - clear the network with docker-compose down       - 'restart' - restart the network       - 'generate' - generate required certificates and genesis block       - 'upgrade'  - upgrade the network from version 1.3.x to 1.4.0     -c <channel name> - channel name to use (defaults to "mychannel")     -t <timeout> - CLI timeout duration in seconds (defaults to 10)     -d <delay> - delay duration in seconds (defaults to 3)     -s <dbtype> - the database backend to use: goleveldb (default) or couchdb     -l <language> - the programming language of the chaincode to deploy: go (default), javascript, or java     -i <imagetag> - the tag to be used to launch the network (defaults to "latest")     -a - launch certificate authorities (no certificate authorities are launched by default)     -n - do not deploy chaincode (abstore chaincode is deployed by default)     -v - verbose mode   byfn.sh -h (print this message)  Typically, one would first generate the required certificates and  genesis block, then bring up the network. e.g.:   byfn.sh generate -c mychannel  byfn.sh up -c mychannel -s couchdb         byfn.sh up -c mychannel -s couchdb -i 1.4.0  byfn.sh up -l javascript  byfn.sh down -c mychannel         byfn.sh upgrade -c mychannel  Taking all defaults:  byfn.sh generate  byfn.sh up  byfn.sh down 

  言归正传,执行以下命令

./byfn.sh up -a true 

  由此etcd raft SDK测试网络搭建完成

关于启用/关闭 TLS

  启用/关闭 TLS 请修改fabric-samples/first-network/base/目录下的peer-base.yaml

  Orderer节点:

- ORDERER_GENERCORE_PEER_TLS_ENABLED=true 

  Peer节点:

- CORE_PEER_TLS_ENABLED=true
