HyperLeger Fabric安装

安装curl、git

yum -y install curl
yum -y install git

安装docker

下载fabric

mkdir hyperledgerFabric
cd hyperledgerFabric
git clone https://github.com/hyperledger/fabric.git

安装fabric-samples示例

cd fabric/scripts
git clone -b main https://github.com/hyperledger/fabric-samples.git

安装二进制文件，解压后将自动安装到fabric-samples目录下的bin和config目录下

wget https://github.com/hyperledger/fabric/releases/download/v2.4.2/hyperledger-fabric-linux-amd64-2.4.2.tar.gz
tar -xzvf hyperledger-fabric-linux-amd64-2.4.2.tar.gz -C fabric-samples

制作成docker镜像
修改bootstrap.sh文件内容并运行即可成功制作成docker镜像

cd fabric/scripts
vim bootstrap.sh

BINARIES=false  # 将136行的BINARIES的true改为false

./bootstrap.sh  # 运行安装脚本

成功运行后查看docker容器

启动测试网络
       创建一个由两个对等节点和一个排序节点组成的Fabric网络

cd /fabric-samples/test-network

./network.sh up

如果报错可以运行下面的命令
curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

创建一个通道

./network.sh createChannel

遇见如下问题的解决方法
       Error: failed to normalize chaincode path: failed to determine module root: exec: “go”: executable file not found in $PATH
       Chaincode packaging has failed
       Deploying chaincode failed

安装go

cd ~
mkdir go
cd go
wget https://dl.google.com/go/go1.14.2.linux-amd64.tar.gz
tar -C /usr/local -zxf go1.14.2.linux-amd64.tar.gz
vim /etc/profile
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$HOME/go/bin

更新配置文件
source /etc/profile
go version

遇见如下问题解决方法
       Error: failed to normalize chaincode path: ‘go list’ failed with: go: github.com/golang/[email protected]: Get “https://proxy.golang.org/github.com/golang/protobuf/@v/v1.3.2.mod”: dial tcp 142.251.43.17:443: i/o timeout: exit status 1
       Chaincode packaging has failed
       Deploying chaincode failed

go env -w GOPROXY=https://goproxy.io,direct
go env -w GO111MODULE=on

链码测试

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

出现一下问题
       Error: chaincode install failed with status: 500 - failed to invoke backing implementation of ‘InstallChaincode’: chaincode already successfully installed (package ID ‘basic_1.0:dee2d612e15f5059478b9048fa4b3c9f792096554841d642b9b59099fa0e04a4’)
       Chaincode installation on peer0.org1 has failed
       Deploying chaincode failed

解决

go env -w GOPROXY=https://goproxy.io,direct
go env -w GO111MODULE=on
go mod vendor

或者重新启动镜像
./network.sh down
./network.sh up createChannel
./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

成功后如下
