hyperledger fabric 1.0.5 分布式部署 （一）

环境是个人虚拟机ubuntu 16.04 64 位版本

前期用户需要先安装好：gcc、g++、git 软件

• 安装 golang  

首先给环境安装一个 go 语言环境，版本最好在1.8 以上

golang 下载地址：https://golang.org/doc/install?download=go1.8.5.linux-amd64.tar.gz （貌似要科学上网）

解压 golang 包 

tar -zxvf /root/go1.8.5.linux-amd64.tar.gz  -C /opt

设置GOPATH

创建一个GOPATH 目录

mkdir -p /opt/gopath

设置 ~/.bashrc 环境配置文件

export GOROOT=/opt/go
export GOPATH=/opt/gopath
export PATH=$PATH:$GOROOT/bin:${GOPATH}/bin

 然后source 让其生效

source ~/.bashrc

 下载 gopm，gopm 执行文件将在 /opt/gopath/bin 目录下，执行以下go 命令前，需要确保系统已经安装了 git 命令

go get -u github.com/gpmgo/gopm

• 修改apt-get 的软件源，调整为国内源

sed -i "s/us./cn./g" /etc/apt/sources.list

或者直接使用 aliyun 的apt-get 源，直接将以下内容写入到  /etc/apt/source.list 文件

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
# 源码
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
# Canonical 合作伙伴和附加
deb http://archive.canonical.com/ubuntu/ xenial partner

然后更新以下apt-get 的库表

apt-get update

• ubuntu 安装系统依赖库，如果安装失败，可以先apt-get update 一下

apt-get install -y libsnappy-dev zlib1g-dev libbz2-dev libltdl-dev libtool 

• ubuntu 安装docker 

安装一些基础库

apt-get install apt-transport-https ca-certificates

新增GPG 密钥

apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

增加docker 的下载源

echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" > /etc/apt/sources.list.d/docker.list

更新apt-get 源

apt-get update

查看可以安装的 docker 版本

apt-cache policy docker-engine

安装docker

apt-get install docker-engine

查看docker 版本

docker version

启动 docker 服务

service docker start

 安装 docker-compose 

由于 docker-compose 需要依赖 python-pip ，利用apt-get 安装python-pip

apt-get install python-pip

利用 pip 安装 docker-compose

pip install docker-compose

安装完成后，执行以下命令验证是否安装成功

docker-compose version

• 从 github 上获取代码

创建目录

mkdir -p $GOPATH/src/github.com/hyperledger ; 
cd $GOPATH/src/github.com/hyperledger 

使用 git download 源码

git clone https://github.com/hyperledger/fabric.git

 切换一下路径

cd $GOPATH/src/github.com/hyperledger/fabric

切换 fabric 的版本

git checkout v1.0.5

安装一些 golang 的库

（如果是利用docker 镜像源下载fabric 镜像的话，这些依赖包貌似没有太大的用处，用户可以不安装）

go get -u github.com/gpmgo/gopm ;
go get github.com/golang/protobuf/protoc-gen-go ; 
go get github.com/kardianos/govendor ; 
go get github.com/golang/lint/golint ;
go get github.com/onsi/ginkgo/ginkgo ;
go get github.com/axw/gocov/... ;
go get github.com/client9/misspell/cmd/misspell ; 
go get github.com/Aleksi/gocov-xml ;
gopm get -g -d golang.org/x/tools/cmd/goimports ;
go install golang.org/x/tools/cmd/goimports ;

配置aliyun 的docker 镜像源，加速下载

aliyun的 docker 镜像仓库地址：

https://cr.console.aliyun.com/?spm=5176.2020520152.1001.13.2d9d45eej2T7DB#/accelerator

注册登录后，按照下图操作，获取到属于自己的镜像地址

 在shell 中执行

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://********.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

切换路径

cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli

修改download-dockerimages.sh 文件权限

chmod 755 download-dockerimages.sh

下载fabric 的相关docker 镜像，由于修改了docker 源，所以整体来说下载速度还挺快

./download-dockerimages.sh -c x86_64-1.0.5 -f x86_64-1.0.5

• 部署和测试 e2e 应用

切换路径

cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli 

修改 /etc/resolv.conf 配置，将 options timeout:2 attempts:3 rotate single-request-reopen 内容注释掉，作者修改后的内容如下

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 100.100.2.136
nameserver 100.100.2.138
# options timeout:2 attempts:3 rotate single-request-reopen

执行启动命令，它会启动一个 mychannel 的channel 

./network_setup.sh up mychannel

 成功后有如下截图

进入到docker 的shell 中

docker exec -it cli bash

查看a 用户有多少余额

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

显示下图

如果要转帐20 元给b，执行以下命令

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"]}'

再来查看a的余额，就变为70元

•  关闭e2e_cli 的demo服务

退出docker 容器的命令行模式

exit

关闭 myChannel 

./network_setup.sh down myChannel

到此，fabric 环境的搭建和演示就结束了。

错误解决：

1 在对 fabric 进行编译时，make docker 出错，错误信息如下

mkdir -p build/image/ccenv/payload
cp build/docker/gotools/bin/protoc-gen-go build/bin/chaintool build/goshim.tar.bz2 build/image/ccenv/payload
cp: 无法获取"build/docker/gotools/bin/protoc-gen-go" 的文件状态(stat): 没有那个文件或目录
make: *** [build/image/ccenv/payload] 错误 1

解决方法，将 protoc-gen-go 工具到对应的目录

cp /opt/gopath/bin/protoc-gen-go build/docker/gotools/bin/

 2 在启动 e2e 应用时出错

如果出现以下错误，则证明 docker-compose 工具没有成功安装，需要用户自己安装

./network_setup.sh:行66: docker-compose: 未找到命令
ERROR !!!! Unable to pull the images 

3 在启动 e2e 应用时出错

如果出现以下错误

2018-01-25 08:11:11.384 UTC [msp] GetDefaultSigningIdentity -> DEBU 002 Obtaining default signing identity

!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

都是因为环境遗留的问题

解决方式，重新关闭网络

./network_setup.sh down mychannel

 如果是在阿里云机器上部署fabric ，在e2e_cli 启动网络时，遇到以下错误

用户则需要修改 /etc/resolv.conf 配置，将 options timeout:2 attempts:3 rotate single-request-reopen 这一行内容注释掉

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 100.100.2.136
nameserver 100.100.2.138
# options timeout:2 attempts:3 rotate single-request-reopen

这个解决方法是从 https://yq.aliyun.com/articles/238940 看到的，作者试过，给增加 GODEBUG=netdns=go 环境变量也不好使，只会又出现以下问题

  -v, --version                    Display current version of fabric peer server

!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

而真正能够彻底解决的方法，就是将 /etc/resolv.conf 注释掉  options timeout:2 attempts:3 rotate single-request-reopen ，就能够正常启动了
