9. 基于现有节点新增一条链(普通证书模式)

9.1. 使用脚本部署四节点单链(普通证书模式)

9.1.1. 证书生成

  • 进入chainmaker-go/scripts目录,执行prepare.sh脚本生成单链4节点集群配置,存于路径chainmaker-go/build

# 进入脚本目录
$ cd ../scripts
# 查看脚本帮助
$ ./prepare.sh -h
Usage:  
  prepare.sh node_cnt(1/4/7/10/13/16) chain_cnt(1-4) p2p_port(default:11301) rpc_port(default:12301)
    eg1: prepare.sh 4 1
    eg2: prepare.sh 4 1 11301 12301

# 生成单链4节点集群的证书和配置
$ ./prepare.sh 4 1
begin check params...
begin generate certs, cnt: 4
input consensus type (0-SOLO,1-TBFT(default),3-HOTSTUFF,4-RAFT,5-DPOS):
input log level (DEBUG|INFO(default)|WARN|ERROR):
enable docker vm (YES|NO(default))
begin generate node1 config...
begin generate node2 config...
begin generate node3 config...
begin generate node4 config...

9.1.2. 编译和安装包制作

  • 生成证书(prepare.sh脚本)后执行build_release.sh脚本,将编译chainmaker-go模块,并打包生成安装,存于路径chainmaker-go/build/release

$ ./build_release.sh
$ tree ../build/release/
../build/release/
├── chainmaker-v2.0.0-wx-org1.chainmaker.org-20210406194833-x86_64.tar.gz
├── chainmaker-v2.0.0-wx-org2.chainmaker.org-20210406194833-x86_64.tar.gz
├── chainmaker-v2.0.0-wx-org3.chainmaker.org-20210406194833-x86_64.tar.gz
├── chainmaker-v2.0.0-wx-org4.chainmaker.org-20210406194833-x86_64.tar.gz
└── crypto-config-20210406194833.tar.gz

9.1.3. 启动节点集群

  • 执行cluster_quick_start.sh脚本,会解压各个安装包,调用bin目录中的start.sh脚本,启动chainmaker节点

$ ./cluster_quick_start.sh normal

9.2. 修改节点配置文件 chainmaker.yml

修改所有节点build/release/chainmaker-v2.3.0_alpha-wx-orgN.chainmaker.org/config/wx-orgN.chainmaker.org中的chainmaker.yml, 如:build/release/chainmaker-v2.3.0_alpha-wx-org1.chainmaker.org/config/wx-org1.chainmaker.org/chainmaker.yml。将chainmaker.yml中:

blockchain:
  # chain id and its genesis block file path.
  - chainId: chain1
    genesis: ../config/wx-org1.chainmaker.org/chainconfig/bc1.yml
#  - chainId: chain2
#    genesis: ../config/{org_path2}/chainconfig/bc2.yml

修改为

blockchain:
  # chain id and its genesis block file path.
  - chainId: chain1
    genesis: ../config/wx-org1.chainmaker.org/chainconfig/bc1.yml
  - chainId: chain2
    genesis: ../config/wx-org1.chainmaker.org/chainconfig/bc2.yml

9.3. 创建新链的创世块配置文件 bc2.yml

复制所有节点build/release/chainmaker-v2.3.0_alpha-wx-orgN.chainmaker.org/config/wx-orgN.chainmaker.org/chainconfig中的bc1.ymlbc2.yml, 如:build/release/chainmaker-v2.3.0_alpha-wx-org1.chainmaker.org/config/wx-org1.chainmaker.org/chainconfig/bc2.yml

修改所有节点release/chainmaker-v2.3.0_alpha-wx-orgN.chainmaker.org/config/wx-org1.chainmaker.org/chainconfigbc2.yml

# chain id
chain_id: chain1

chain_id 修改为定义好的新链的id

eg:
# chain id
chain_id: chain2

9.4. 使用cmc命令动态启动新增链

需要连接到各个节点,动态加载每个节点中的新增链配置

./cmc client blockchains checknew --sdk-conf-path=./testdata/sdk_config.yml

9.5. 新增链链配置验证

修改cmc/testdata/sdk_config.yml

  # 链ID
  chain_id: "chain1"

chain_id 修改为新增链id

eg:
  # 链ID
  chain_id: "chain2"

使用cmc命令查询新增链链配置

./cmc client chainconfig query \
--sdk-conf-path=./testdata/sdk_config.yml
