ubuntu16.04 HyperLedger Fabric 1.2.0 开发环境搭建

安装准备

1. 安装git、cRUL、gcc/g++和make

$ sudo apt-get update

$ sudo apt-get install build-essential git curl make

$ $ which gcc

/usr/bin/gcc

2. 安装Docker和Docker Compose

安装Docker-CE

参考: ubuntu16.04下docker安装和简单使用

! 注意安装的docker版本是否满足要求

查看docker版本

$ docker --version

Docker version 18.06.1-ce, build e68fc7a

安装docker-compose

! 注意版本

参考:

docker-compose安装

# 下载

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 添加写权限

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

# 查看docker-compose版本

$ docker-compose --version

docker-compose version 1.22.0, build f46880fe

3. 安装go

go下载地址

! 注意go版本是否满足要求

1) 安装

$ wget https://dl.google.com/go/go1.10.1.linux-amd64.tar.gz

$ tar zxvf go1.10.1.linux-amd64.tar.gz

$ sudo mv go /usr/local/

$ mkdir -p ~/go/{src,bin}

$ vi ~/.bashrc

2) 设置环境变量

需要在~/.bashrc中设置环境变量GOPATH,GOROOT,PATH,例如:

export GOROOT=/usr/local/go

export GOPATH=~/go

export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:.

保存退出,使得配置立即生效

source ~/.bashrc

3) 验证配置是否正常

$ echo $GOROOT

/usr/local/go

$ echo $GOPATH

/home/bob/go

$ which go

/usr/local/go/bin/go

4. 安装Nodejs和NPM

! 注意版本

参考: nodejs ubuntu安装

# 查看版本

$ node -v

v8.11.4

$ npm -v

5.6.0

5. 安装python

# 安装python

$ sudo apt-get install python

$ python -V

Python 2.7.12

# 安装pip

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py 

# 切换到root用户

$ su

# python get-pip.py

!!!!!! 友情提示: 如果使用了VMware Workstation,做到这里的时候，最好先使用快照(snapshot)进行快速备份,防止之后出现莫名其妙的问题实在解决不了，可以从备份点恢复再来，以免完全重新开始,创建虚拟机。

使用脚本安装fabric

1. 下载启动脚本并安装

$ cd ~

$ mkdir hyperledger-fabric

$ cd hyperledger-fabric

$ curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/release-1.2/scripts/bootstrap.sh -o bootstrap.sh

$ ls

bootstrap.sh

$ chmod +x bootstrap.sh

$ ./bootstrap.sh 1.2.0 1.2.0 0.4.10

注意:

hyperledger-fabric

和

hyperledger-fabric-ca下载速度较慢

可以考虑使用代理加速下载

安装过程记录:

===> List out hyperledger docker images

hyperledger/fabric-couchdb     latest              3092eca241fc

2. 设置环境变量

在PATH中加入_//hyperledger-fabric/fabric-samples/bin,形如:

$ vi ~/.bashrc

# 修改PATH

export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:~/hyperledger-fabric/fabric-samples/bin:.

使得环境变量立即生效

$ source ~/.bashrc

测试修改是否生效

$ fabric-ca-client version

fabric-ca-client:

 Version: 1.2.0

 Go version: go1.10

 OS/Arch: linux/amd64

3. 创建和管理网络

1> 生成数字证书和创世区块

$ cd ~/hyperledger-fabric/fabric-samples/first-network/

$ ./byfn.sh generate

Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

Continue? [Y/n] y

proceeding ...

/home/bob/hyperledger-fabric/fabric-samples/first-network/../bin/cryptogen

...

其中byfn.sh为启动这个网络的启动脚本，启动脚本中除建立一个包含4个节点和1个Order service的网络外，还会启动一个容器用来执行脚本在channel中加入节点，部署和初始化chaincode，以及在部署的chaincode上执行交易。默认channel名称为mychannel，脚本程序会给网络实例生成数字证书和密钥；生成genesis block用来启动ordering service；一些用来配置channel的配置交易

2> 使用docker-compose启动网络

$ ./byfn.sh up

Starting for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

Continue? [Y/n] y

proceeding ...

LOCAL_VERSION=1.2.0

...

安装过程记录:

使用docker ps来查看节点启动情况

使用docker images查看安装镜像

关闭网络

使用./byfn.sh down

$ ./byfn.sh down

Stopping for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

Continue? [Y/n] y

proceeding ...
