FISCO BCOS区块链建立配置启动

搭建一条区块链

安装依赖

sudo yum install -y openssl openssl-devel

创建操作目录, 下载安装脚本

cd ~ && mkdir -p fisco && cd fisco//创建操作目录

curl -#LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.9.0/build_chain.sh && chmod u+x build_chain.sh//下载安装脚本

搭建单群组4节点联盟链

bash build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545

启动FISCO BCOS链

bash nodes/127.0.0.1/start_all.sh

---

配置及使用控制台

安装java

sudo yum install -y java java-devel

获取控制台并回到fisco目录

cd ~/fisco && curl -LO https://github.com/FISCO-BCOS/console/releases/download/v2.9.1/download_console.sh && bash download_console.sh

拷贝控制台配置文件

cp -n console/conf/config-example.toml console/conf/config.toml

配置控制台证书

cp -r nodes/127.0.0.1/sdk/* console/conf/

启动并使用控制台

cd ~/fisco/console && bash start.sh

部署及调用HelloWorld合约

编写HelloWorld合约

pragma solidity ^0.4.24;

contract HelloWorld {
string name;

function HelloWorld() {
    name = "Hello, World!";
}

function get()constant returns(string) {
    return name;
}

function set(string n) {
    name = n;
}

}

部署HelloWorld合约

[group:1]> deploy HelloWorld
transaction hash: 0xd0305411e36d2ca9c1a4df93e761c820f0a464367b8feb9e3fa40b0f68eb23fa
contract address:0xb3c223fc0bf6646959f254ac4e4a7e355b50a344
