fabric1.4 简书
开发先决条件：
Git客户端
Go - 版本1.12.x
Docker - 17.06.2-ce或更高版本
Docker Compose - 1.14.0或更高版本
#（macOS） 必须安装Xcode
安装git
yum -y install gcc-c++ wget
yum -y install git安装docker
yum install -y yum-utils
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast
yum install docker-ce -y
systemctl start docker
systemctl enable docker安装docker-compose,负责实现对Docker容器集群的快速编排
yum -y install epel-release
yum -y install python-pip
pip --version
pip install --upgrade pip
pip install docker-compose
yum install bash-completion -y
docker-compose version安装go语言
wget https://dl.google.com/go/go1.12.9.linux-amd64.tar.gz
tar -xf go1.12.9.linux-amd64.tar.gz
mv go /usr/local/
echo "export PATH=$PATH:/usr/local/go/bin" >>/etc/profile
source /etc/profile安装Node.js Runtime and NPM
fabric目前不支持低于8.x系列的其他版本
wget https://npm.taobao.org/mirrors/node/v8.9.4/node-v8.9.4-linux-x64.tar.xz
tar xf node-v8.9.4-linux-x64.tar.xz
mv node-v8.9.4-linux-x64/ /usr/local/nodejs
chown -R root.root /usr/local/nodejs/
ln -s /usr/local/nodejs/bin/node /usr/bin/node
echo "export PATH=$PATH:/usr/local/nodejs/bin" >>/etc/profile
source /etc/profile
npm config set registry https://registry.npm.taobao.org
npm config get registry
npm install express -g
node -v
npm -v
安装fabric二进制文件和Docker镜像
cd /usr/local/go/src/
mkdir -p github.com/hyperledger
cd github.com/hyperledger
yum -y install libtool libltdl-dev
wget https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh
chmod +x ./bootstrap.sh
./bootstrap.sh安装成功如下：
......

建立第一个网络
yum install softhsm -y
cd /usr/local/go/src/github.com/hyperledger/fabric-samples/first-network
生成网络工件
./byfn.sh generate
启动网络(不知道为什么我每次都需要启动两次才能成功，第一次up之后要先down掉再up)
./byfn.sh up
./byfn.sh down查看docker运行的容器：
[root@localhost first-network]# docker ps

测试转账：
docker exec -it cli bash
查询
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'export CHANNEL_NAME=mychannel转账
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]}'invoke1.2之后（包含1.2）需要check --peer这个参数
1.2 之前的官方脚本：
peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}'1.2之后官方脚本：
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc $PEER_CONN_PARMS -c '{"Args":["invoke","a","b","10"]}'
注意：
上面是虚拟机测试环境，如果用阿里云的服务器启动会报错如下：
Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp: lookup peer0.org1.example.com: no such host"
peer0.org1 failed to join the channel, Retry after 3 seconds
原因是阿里云服务bug不兼容fabric
解决如下：
vim /usr/local/go/src/github.com/hyperledger/fabric-samples/first-network/base/docker-compose-base.yaml
在每个environment下面都追加下面的参数，然后重新up就搞定。
