1. 環境搭建
Install Common Packages
# install utilities
$ brew install unzip
$ brew install git
$ brew install curl
$ brew install wget
$ brew install vim
$ brew install tree
$ brew install jq
# install gradle
$ cd /tmp && wget https://services.gradle.org/distributions/gradle-6.4-bin.zip
$ unzip gradle-6.4-bin.zip
$ sudo mv gradle-6.4 /usr/local/gradle
$ sudo cat >> ~/.zshrc <<EOF
# setup gradle environments
# =====================
export PATH=$PATH:/usr/local/gradle/bin # =====================
EOF
$ source ~/.zshrc
下載 Docker Images
# image of ca
$ docker pull hyperledger/fabric-ca:1.4.6
# image of peer
$ docker pull hyperledger/fabric-peer:2.1.0
# image of orderer
$ docker pull hyperledger/fabric-orderer:2.1.0
# image of tools & utilities
$ docker pull hyperledger/fabric-tools:2.1.0
# image of Chaincode deployment for Programming Languages (Go | Java | Node.JS) $ docker pull hyperledger/fabric-ccenv:2.1.0
$ docker pull hyperledger/fabric-javaenv:2.1.0
$ docker pull hyperledger/fabric-nodeenv:2.1.0
# image of Base-OS of Chaincode runtime
$ docker pull hyperledger/fabric-baseos:0.4.20
# image of coucddb (one NOSQL DB for ledger state)
$ docker pull hyperledger/fabric-couchdb:0.4.20
# check image list to validate downloading
$ docker images
安裝完畢以后的鏡像串列
Install docker-compose
前置操作，安裝 wget
% brew install wget
如果出現python3的錯誤，請先remove掉python3
brew uninstall python3
在安裝一遍
brew install python
根據命令的提示，建立連接
brew link --overwrite python@3.8
開始安裝 docker-compose
# download
$ wget https://github.com/docker/compose/releases/download/1.25.3/docker-compose-`uname -s`-`uname -m`
# copy to ` /usr/local/bin/ ` and rename
$ sudo mv docker-compose-`uname -s`-`uname -m` /usr/local/bin/docker-compose
# make executable
$ sudo chmod +x /usr/local/bin/docker-compose
# validate installation
$ docker-compose -v
# docker-compose version 1.25.4, build unknown
Install Go language SDK
筆者用的是zsh所以，組態檔路徑在 ~/.zshrc， 如果用的是bash，組態檔路徑在~/.bashrc， 在下面的命令中修改組態檔路徑即可.
golang下載路徑： https://golang.org/dl/
如果Terminal下載golang失敗，可以瀏覽器下載成功以后，copy到/tmp 下，
# install Go
$ cd /tmp && wget https://golang.org/dl/go1.13.14.darwin-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.13.14.darwin-amd64.tar.gz
$ sudo cat >> ~/.zshrc <<EOF
# setup go environments
# =====================
export GO_HOME="/usr/local/go"
export PATH=$GO_HOME/bin:$PATH
export GOPATH=$HOME/gopath
export GO111MODULE=on
export GOPROXY=https://goproxy.cn
# =====================
EOF
$ source ~/.zshrc
$ go version
# go version go1.13.14 darwin/amd64
install Java SDK
# install Java
$ sudo apt-get update
$ sudo apt-get install -y openjdk-8-jdk
$ java -version
# 筆者之前已經安裝好JDK，資訊如下，上面的命令應該是正常的
# java version "1.8.0_172"
# Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
# Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)
Install Node.JS via NVM
用 homebrew 安裝 nvm
$ brew install nvm
編輯組態檔
$ vim ~/.zshrc
# 如果用的bash請用 vim ~/.bashrc
$ export NVM_DIR=~/.nvm
# 保存 esc > :wq
重新加載組態檔
$ source $(brew --prefix nvm)/nvm.sh
$ nvm --version
# 0.36.0
# install Node.JS version 10
$ nvm install 10
# check the version of Node.JS and NPM
$ node -v
# v10.22.1
$ npm -v
# 6.14.6
#Tips: NVM Vs. NPM
- NVM： Node Version Manager
- NPM： Node Package Manager
Download workspace
# download workspace from gitlab.com
$ git clone https://gitlab.com/qubing/blockchain_lab_v2.git ~/Workspace/blockchain
Download Fabric Binaries
$ vim ~/.zshrc
# set block chain environment variables begin
export BLOCK_CHAIN_BASE_PATH=https://github.com/hyperledger
export BLOCK_CHAIN_FABRIC_VERSION=2.1.0
export BLOCK_CHAIN_CA_VERSION=1.4.6
export BLOCK_CHAIN_ARCH=$(echo "$(uname -s|tr '[:upper:]' '[:lower:]'|sed 's/mingw64_nt.*/windows/')-$(uname -m | sed 's/x86_64/amd64/g')")
export BLOCK_CHAIN_FILE_NAME=hyperledger-fabric-${BLOCK_CHAIN_ARCH}-${BLOCK_CHAIN_FABRIC_VERSION}.tar.gz
export BLOCK_CHAIN_CA_FILE_NAME=hyperledger-fabric-ca-${BLOCK_CHAIN_ARCH}-${BLOCK_CHAIN_CA_VERSION}.tar.gz
# set block chain environment variables end
# esc > :wq
$ source ~/.zshrc
$ cd /tmp
# download fabric binaries and fabric-ca binaries
# 下載太慢，手動下載Tips: download link on pan.baidu.com
# 鏈接:https://pan.baidu.com/s/1PSFgdKt6ijcu4UFDyAa9UA
# 提取碼:8p2z
$ mkdir -p ~/Workspace/blockchain/fabric-bin/${BLOCK_CHAIN_FABRIC_VERSION} && cd ~/Workspace/blockchain/fabric-bin
$ wget $BLOCK_CHAIN_BASE_PATH/fabric/releases/download/v$BLOCK_CHAIN_FABRIC_VERSION/$BLOCK_CHAIN_FILE_NAME
$ wget $BLOCK_CHAIN_BASE_PATH/fabric-ca/releases/download/v$BLOCK_CHAIN_CA_VERSION/$BLOCK_CHAIN_CA_FILE_NAME
# copy binaries
$ tar zxf ./$BLOCK_CHAIN_FILE_NAME
$ tar zxf ./$BLOCK_CHAIN_CA_FILE_NAME
$ chmod +x bin/* && sudo cp bin/* /usr/local/bin/
2. 環境搭建起來后，環境架構介紹
Initialize & Startup Network
# STEPS for Startup Environment
# 1. startup CA servers
# 2. register accounts for each organizations including (admin, users, peers) # 3. generate genesis blocks and channel setup transaction files
# 4. startup Orderer and Peers with DB
# 5. setup channel
# 6. generate connection profile for each peer
$ cd ~/Workspace/blockchain
$ sudo -s . ./init.sh
查看正在運行的container
# You can run docker command `docker ps -a` to check containers generated
$ docker ps
