在 Ubuntu 上安装和设置 Loom
Ubuntu 包
sudo apt -y install curl unzip make git
Golang
官方途径
curl -O https://dl.google.com/go/go1.10.2.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.10.2.linux-amd64.tar.gz
假设你使用 bash,如果 zsh 执行 ~/.zshrc
:
echo -e "\nexport PATH=\$PATH:/usr/local/go/bin:~/gopath/bin" >> ~/.bashrc
source ~/.bashrc
Protobuf
https://github.com/google/protobuf/releases/
export PROTOBUF_VERSION=3.5.1
curl -OL https://github.com/google/protobuf/releases/download/v${PROTOBUF_VERSION}/protoc-${PROTOBUF_VERSION}-linux-x86_64.zip
sudo unzip protoc-${PROTOBUF_VERSION}-linux-x86_64.zip -d /usr/local
sudo chmod +x /usr/local/bin/protoc
Dep
mkdir -p ~/gopath/bin
export GOPATH=~/gopath
curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
安装
curl -OL https://downloads.loomx.io/loom/linux/stable/loom
chmod +x loom
export GOPATH=~/gopath
export PATH=$GOPATH/bin:$PATH
./loom spin weave-blueprint
cd blueprint
export GOPATH=$GOPATH:`pwd`
make deps
make
cd build
../../loom init
cp ../genesis.example.json genesis.json
运行区块链:
../../loom run
发送事务
打开第二个控制台
这将生成私钥。 创建一个帐户。 然后设置一个值,接着从区块链中读取值。
你可以在这里读取 blueprint 合约 源代码
cd blueprint/build
../../loom genkey -k priv_key -a pub_key
./blueprint call create-acct -p priv_key
./blueprint call set -v 1 -p priv_key
./blueprint call get
