1.环境搭建

1.1 go的按装及配置

1.1.1下载go压缩包

wget https://dl.google.com/go/go1.9.2.linux-amd64.tar.gznode

1.1.2 解压

tar -C /usr/local -zxvf go1.9.2.linux-amd64.tar.gzpython

1.1.3配置环境变量

vi ~/.bash_profile

添加以下内容：linux

PATH=$PATH:$HOME/bin
export PATH
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$HOME/go/bin

使环境变量生效c++

source  ~/.bash_profile

1.2 安装Docker

1.2.1 检查是否已经安装

rpm -qa|grep dockergit

1.2.2 卸载旧版本

yum remove docker docker-client docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine

1.2.3 安装须要的软件包

yum install -y yum-utils device-mapper-persistent-data lvm2

1.2.4设置 stable 源

yum-config-manager --add-repo http://download.docker.com/linux/centos/docker-ce.repo

1.2.5 启用启用 docker-ce-edge和docker-ce-test（可选）

yum-config-manager --enable docker-ce-edge
yum-config-manager --enable docker-ce-tes

1.2.6 安装 Docker CE

yum install docker-ce

1.2.7 启动docker

service docker start

1.2.8 加入开机启动

chkconfig docker on

1.2.9 测试是否安装成功

docker --version

1.2.10 安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.20.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

1.2.11 测试docker-compose是否安装成功

docker-compose version

1.3 安装python-pip

yum -y install epel-release
yum -y install python-pip

1.4 安装node.js

## root 
curl -sL https://rpm.nodesource.com/setup_10.1 | bash -
## no root
curl -sL https://rpm.nodesource.com/setup_10.1 | sudo bash -
yum install -y nodejs

1.5 升级gcc

wget http://ftp.gnu.org/gnu/gcc/gcc-9.1.0/gcc-9.1.0.tar.gz
tar -C /usr/local -xzf gcc-9.1.0.tar.gz
 cd /usr/local/gcc-9.1.0
 ./contrib/download_prerequisites 
 mkdir build
  cd build/
 ../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
  yum groupinstall "Development Tools" 
 make
 make install

1.6 安装npm

$ npm install npm -g
$ npm -v

1.7 fabric下载

1.7.1 下载fabric源码

## 下载源码
$ mkdir -p ~/go/src/github.com/hyperledger 
$ cd ~/go/src/github.com/hyperledger 
$ git clone https://github.com/hyperledger/fabric.git
## 切换到v1.0.0版本
$ cd ~/go/src/github.com/hyperledger/fabric
$ git checkout v1.0.0

1.7.2 下载 Fabric Docker镜像

$ cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
$ source download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0

1.7.3 检查下载的镜像列表

docker images

1.7.4 测试Fabric环境是否成功

cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli
./network_setup.sh up

该指令作了一下操做github

1.编译生成Fabric公私钥、证书的程序，程序在目录：fabric/release/linux-amd64/bin
2.基于configtx.yaml生成创世区块和通道相关信息，并保存在channel-artifacts文件夹。
3.基于crypto-config.yaml生成公私钥和证书信息，并保存在crypto-config文件夹中。
4.基于docker-compose-cli.yaml启动1Orderer+4Peer+1CLI的Fabric容器。
5.在CLI启动的时候，会运行scripts/script.sh文件，这个脚本文件包含了建立Channel，加入Channel，安装Example02，运行Example02等功能。docker

运行完若是出现下图所示，说明整个Fabric网络已经通了.
shell

2.测试Fabric网络

Fabric提供了SDK和CLI两种交互方式，咱们使用的是CLI 。npm

使用官方提供的小例子进行测试，在官方例子中，channel名字是mychannel，链码（智能合约）的名字是mycc。
首先要登陆到CLI这个容器中，才能执行Fabric的CLI命令：centos

docker exec -it cli bash

这时用户名变为root@44084971aff7，当前目录变为/opt/gopath/src/github.com/hyperledger/fabric/peer#，接着可执行peer命令，体验区块链的命令行使用方式。

2.1 查看帐户余额

root@44084971aff7:/opt/gopath/src/github.com/hyperledger/fabric/peer#  peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

结果：

Query Result: 90

这里90就是a帐户的余额

2.2 调用链码，转帐

让b帐户向a帐户转帐10：

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 -c '{"Args":["invoke","a","b","20"]}'

再次执行查询（由于转帐操做了2次因此此处是50）

root@c259da3de4d1:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

2.3 退出cli容器

直接执行

exit

关闭Fabric

cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli
./network_setup.sh down

3.遇到的问题

3.1 使用wget、curl、git报command not found

缘由：未安装wget、curl

解决

yum install -y wget
yum install -y curl
yum install -y git

3.2 安装docker-compose问题

Failed connect to github-production-release-asset-2e65be.s3.amazonaws.com:443; Connection timed out

缘由：该地址(github-production-release-asset-2e65be.s3.amazonaws.com) 须要的一些下载的访问被国内屏蔽了
解决：在hosts中加配置
```
ping github-production-release-asset-2e65be.s3.amazonaws.com
 vi /etc/hosts
```
新增以下配置：

52.216.128.51 github-production-release-asset-2e65be.s3.amazonaws.com

3.3 gcc升级问题

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.，mpfr2.4.0

yum install  gmp  gmp-devel  mpfr  mpfr-devel  libmpc  libmpc-devel

3.4 gcc动态库没有替换问题

node: /usr/lib64/libstdc++.so.6: version GLIBCXX_3.4.21' not found (required by node) node: /usr/lib64/libstdc++.so.6: versionGLIBCXX_3.4.15' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by node)

运行检查命令

strings /usr/lib64/libstdc++.so.6 | grep GLIBC

查找编译gcc时生成的最新动态库

find / -name "libstdc++.so*"
cd /usr/lib64
rm -rf libstdc++.so.6
ln -s libstdc++.so.6.0.26 libstdc++.so.6
strings /usr/lib64/libstdc++.so.6 | grep GLIBC

3.5 Fabric启动报错1

can't load package: package github.com/hyperledger/fabric/core/chaincode/shim: cannot find package

源码路径不对

go env

把fabric源码放在~/go/src/github.com/hyperledger 目录下

3.6 Fabric启动报错2

Error response from daemon: Container is not running

##查看运行的容器
docker ps -a
## 把失败的从新启动
docker start 44084971aff7

3.7 Fabric启动报错3

Error: Error getting endorser client chaincode: PER:404 - Error trying to connect to local peer

从新关闭网络

./network_setup.sh down mychannel

3.8 测试转帐no such file or directory

root@b103ad898190:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -c '{"Args":["invoke","b","a","10"]}'

根证书不对
