Tron节点搭建

波场节点介绍

波场网络的节点主要分为两类：超级节点，全节点

• 超级节点
  包含全网全部区块数据，并负责共识出块
• 全节点
  包含全网全部区块数据

波场节点编译安装

笔者使用波场的master分支， 官方git链接：https://github.com/tronprotocol/java-tron.git

• 服务基础环境
  JDK1.8
  CentOS 7.2 6CUP 16G 300G
• 节点编译安装

创建代码目录
    mkdir -p /home/tron/
下载源码  
    cd /home/tron/
    git clone -b master https://github.com/tronprotocol/java-tron.git
编译源码(本文主要将源码编译成jar形式)
    cd java-tron
    ./gradlew clean shadowJar
编译结果jar文件路径
    /home/tron/java-tron/build/libs/java-tron.jar

运行节点

• a.) 节点需要的jar及配置文件

1. java-tron.jar（/home/tron/java-tron/build/libs/java-tron.jar）
   2.config.conf（/home/tron/java-tron/src/main/resources/config.conf）

• b.) 运行Super Node
  目标：创建超级节点，并开始创建区块

创建节点目录并拷贝相关jar包及配置文件（见a项）

# mkdir -p /home/tron/superNode
# cp /home/tron/java-tron/build/libs/java-tron.jar /home/tron/superNode
# cp /home/tron/java-tron/src/main/resources/config.conf /home/tron/superNode

创建你的tron账号

可通过https://tronscan.org/ 去创建你的个人账号,并保存创建的私钥及地址信息

修改配置文件

• 配置文件：/home/tron/superNode/config.conf
• 修改genesis.block.witnesses为你个人的tron地址
  witnesses = [
  {
  address: 27PsvT28qhmUM1GHMVVJeyRskhB2pfzA1En,
  url= "http://tron.com",
  voteCount = 10000
  }
  ]
• 修改seed.node.ip.list 为服务器的IP:PORT
  seed.node = {
  ip.list = [
  "123.207.xx.xxx:18888"
  ]
  }
• 第一个超级节点，则需要修改needSyncCheck =false
  block = {
  needSyncCheck = false# first node : false, other : true
  maintenanceTimeInterval = 21600000 // 1 day: 86400000(ms), 6 hours: 21600000(ms)
  }
• 可修改p2pversion 为你自己定制的版本，建议不修改该值

启动超级节点:

cd /home/tron/superNode
java -jar java-tron.jar -p 个人地址的私钥 --witness -c /home/tron/superNode/config.conf

验证节点启动状态:

• 节点启动后，java-tron.jar的同级目录上将生成 logs 和 output-directory 两个文件夹
  logs : 节点日志文件
  output-directory : 节点数据存储目录
• 查看日志，确定节点是否正常启动，并在出块

超级节点启动，并创建创世块:

]

超级节点正常出块：

• c.) 运行Full Node
  目标：创建全节点，并连上自建的超级节点同步数据

准备全节点的jar包及配置文件：

• 在全节点服务器上创建节点目录：mkdir -p /home/tron/fullNode
• 拷贝步骤b)的jar包及配置文件到全节点服务器/home/tron/fullNode目录下

修改配置文件：

• 将超级节点加入active列表
  active = [
  "123.207.xx.xxx:18888"
  ]
• 修改needSyncCheck =true
  block = {
  needSyncCheck = true# first node : false, other : true
  maintenanceTimeInterval = 21600000 // 1 day: 86400000(ms), 6 hours: 21600000(ms)
  }

启动全节点：

cd /home/tron/fullNode
java -jar java-tron.jar -c /home/tron/fullNode/config.conf

验证全节点：

• 节点启动后，java-tron.jar的同级目录上将生成 logs 和 output-directory 两个文件夹
  logs : 节点日志文件
  output-directory : 节点数据存储目录
• 查看日志，确定节点是否正常启动，并在同步区块

全节点启动，并创建创世块:

小结

至此已经在个人的私有网络上搭建起波场网络，根据实际需求，可以增加超级节点及全节点；后续笔者则将在此构建私有波场的网络的基础上，介绍如何接入波场的测试网络。
