ubuntu16.04 HyperLedger Fabric 1.2.0 開發環境搭建

安裝準備

1. 安裝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. 安裝Docker和Docker Compose

安裝Docker-CE

參考: ubuntu16.04下docker安裝和簡單使用
! 注意安裝的docker版本是否知足要求
查看docker版本

$ docker --version
Docker version 18.06.1-ce, build e68fc7a

安裝docker-compose

! 注意版本
參考:
docker-compose安裝

# 下載
$ 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
# 添加寫權限
$ 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. 安裝go

go下載地址
! 注意go版本是否知足要求

1) 安裝

$ 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) 設置環境變量

須要在~/.bashrc中設置環境變量GOPATH,GOROOT,PATH,例如:

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

保存退出,使得配置當即生效

source ~/.bashrc

3) 驗證配置是否正常

$ echo $GOROOT
/usr/local/go
$ echo $GOPATH
/home/bob/go
$ which go
/usr/local/go/bin/go

4. 安裝Nodejs和NPM

! 注意版本
參考: nodejs ubuntu安裝

# 查看版本
$ node -v
v8.11.4
$ npm -v
5.6.0

5. 安裝python

# 安裝python
$ sudo apt-get install python 
$ python -V
Python 2.7.12

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

# 切換到root用戶
$ su 
# python get-pip.py

!!!!!! 友情提示: 若是使用了VMware Workstation,作到這裏的時候，最好先使用快照(snapshot)進行快速備份,防止以後出現莫名其妙的問題實在解決不了，能夠從備份點恢復再來，以避免徹底從新開始,建立虛擬機。

使用腳本安裝fabric

1. 下載啓動腳本並安裝

$ 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下載速度較慢
能夠考慮使用代理加速下載

安裝過程記錄:

===> List out hyperledger docker images

hyperledger/fabric-couchdb     latest              3092eca241fc

2. 設置環境變量

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:.

使得環境變量當即生效

$ source ~/.bashrc

測試修改是否生效

$ fabric-ca-client version
fabric-ca-client:
 Version: 1.2.0
 Go version: go1.10
 OS/Arch: linux/amd64

3. 建立和管理網絡

1> 生成數字證書和創世區塊

$ 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爲啓動這個網絡的啓動腳本，啓動腳本中除創建一個包含4個節點和1個Order service的網絡外，還會啓動一個容器用來執行腳本在channel中加入節點，部署和初始化chaincode，以及在部署的chaincode上執行交易。默認channel名稱爲mychannel，腳本程序會給網絡實例生成數字證書和密鑰；生成genesis block用來啓動ordering service；一些用來配置channel的配置交易

2> 使用docker-compose啓動網絡

$ ./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
...

安裝過程記錄:

使用docker ps來查看節點啓動狀況

使用docker images查看安裝鏡像

關閉網絡

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 ...
