泰岳链节点搭建

泰岳链节点搭建

今天尝试搭建一个泰岳链联盟链(4节点)，本地搭建,先在家目录下建立一个目录nodes,在该目录下建立4个子目录node1~node4，并分别在节点目录里建立相应的数据目录(data).

开始申请4个根证书，(证书申请可以使用openssl工具，泰岳链文档中有申请方法)，申请完证书后，还需要为4个节点分别指定一个nodekey，由于是一个全新的联盟链，所以需要重新构建创世区块及bootnode节点，以方便节点启动后能够快速的发现对方。

最后的目录结构如图:

nodekey是一个节点连接的身份标识，通常它以一个私钥对应的公钥来表示，现在对应4个节点我们需要生成4组nodekey相关的私钥并生成节点对应的enode。

./genkey --sum 4 generate
./taiyue endoe privkey
privkey: 表示下方生成的私钥

在构造好enode后，开始构造genesis，使用提供的genesis.json模板，简单起见，我们只改committe字段其他不改。将之前生成的4个公钥填在publickey字段。

  "committee":[
    {
      "address": "0x76ea2f3a002431fede1141b660dbb75c26ba6d97",
      "publickey": "0x04f955a64a54f93bfb1b79a5f6bc899e59b320a1c520fdc01d2df821076f746d448fcd00ff14f8ab9c10aef3dac567c6e9ab2f05ac8e82bda2edaf8cad5ef8a449"
    },
    {
      "address": "0x831151b7eb8e650dc442cd623fbc6ae20279df85",
      "publickey": "0x0463888e7a3ee5c389bbebe335626bcff4056827b0506683a11e2ca269491976c316c948198bf1a1b338bf79afa163c71e7779e89b001b2f299d162934c74cc67d"

    }
  ]

构建好genesis.json后，可以开始创建创世区块了。

./taiyue --datadir “./nodes/node1/data” init genesis.json “./certlist”
注: ./certlist是之前生的4个CA证书的目录,生成后将data目录拷贝node2,node3,node4目录。

生成创世区块后，开始分别配置4个节点的配置文件，分别使用config.toml模板文件。

• [taiyue]

CommitteeKey = "0xc6fc8ff991e0e48ae91d4af0ac7cb757c1ac0ac98d810764b6a86fd6fc9ec3a1"
Host = "192.168.0.101"
Port = 40301
StandbyPort = 40311
> 注： 4节点分别配置之前申请的4组私钥及ip地址，端口分别用{ [40301,40311], [40302,40312], [40303,40313], [40304,40314]}

• [node]

DataDir = "./nodes/node1/data"
HTTPHost = "192.168.0.101"
HTTPPort = 40401
> 注：DataDir配置之前的数据目录,HTTPHost 配各自的IP,端口[40401,40402,40403,40404]

EnableMsgEvents = false

将配置好的config.toml拷贝相应的目录，./nodes/node1/config.toml
至此我们已经做完启动前的所有准备工作，现在可以依次启动服务了。

taiyue --config "./nodes/node1/config.toml
