【區塊鏈秘技 Day1】快速架設tron 全節點

1. 為甚麼需要架設tron節點?

tronscan提供的api與第三方提供的api都有使用次數的限制，自己架設節點可以避免這個問題。

2. 如何解決?

架設Tron全節點可提高區塊鏈網絡的分散性、參與共識運行、確保交易安全、支援去中心化應用（DApps）的運行，同時有助於獲得網絡獎勵及參與治理，增強Tron生態系統的穩定性和可信度。

  • 架設tron全節點，可以取得完整的交易資訊

3. 電腦配置

一般規格

  • CPU: 16核心
  • 記憶體: 32G
  • SSD: 5T (歷史交易紀錄已經快1.9T)
  • 100 MB/s (網路速度)
  • linux 作業系統

超級驗證節點規格 (需要加入私鑰，且為tron質押排名前16名才有資格)

  • CPU: 32核心
  • 記憶體: 64G
  • SSD: 5T (歷史交易紀錄已經快1.9T)
  • 100 MB/s (網路速度)
  • linux 作業系統

tron 全節點架設資訊 java-tron on GitHub.

開始架設

下載tron節點專案

git clone https://github.com/tronprotocol/java-tron.git

安裝JDK8與JRE8

sudo apt-get install openjdk-8-jdk
sudo apt install openjdk-8-jre-headless

#安裝要檢查是否安裝成功
java -version # 檢查JDK8版本
javac -version # 檢查JDE8版本

切換到java-tron資料夾

cd java-tron

建立Fullnode.jar檔

./gradlew clean build -x test # (Fullnode.jar會放在java-tron/build/libs)

切換到java-tron/build/libs路徑底下

cd java-tron/build/libs

建立main_net_config.conf (建立tron 節點的conifg檔，要將main_net_config.conf放置在java-tron/build/libs路徑下)

 vim main_net_config.conf # 建立檔案(一開始為空的，只有檔名)

將官方文件的main_net_config.conf 內容，複製到自己的main_net_config.conf裡面
(https://github.com/tronprotocol/tron-deployment/blob/master/main_net_config.conf)

在main_net_config.conf 裡加入參數搜尋jsonrpc，修改一下參數(註解要移除)

(設置的原因: api 要調用50545與8090端口，50545端口需要設定才能開啟，8090本來就打開了)

設定supportConstant為true(預設為false)，避免tron在解析合約資料時產生CONTRACT_VALIDATE_ERROR的錯誤。

開啟端口50545與50555

運行節點(要先切換到java-tron/build/libs)

 java -Xmx24g -XX:+UseConcMarkSweepGC -jar FullNode.jar -c main_net_config.conf

開啟同步InternalTransaction

將saveInternalTx設為true(原本是false)

缺點:

經過上述步驟之後，tron節點同步速度非常慢

優化:

  • java-tron的DB分成levelDB與rocksDB，conifg 預設為levelDB，官方的歷史交易資料也是使用levelDB。rocksDB可以設置資料備援與叫好的擴充性。levelDB與rocksDB不能混用，會報錯誤。
  1. 建議下載tron官方的歷史交易資料 (https://backup.trongrid.io/)(https://tronprotocol.github.io/documentation-en/using_javatron/backup_restore/)
  2. 目前tron官方歷史交易資料為1.9T，下載會很久，建議(多執行續下載)使用指令
# 第一次使用需要安裝
sudo apt-get install axel
nohup axel -a -n 40 https://fullnode-backup-3.s3-ap-southeast-1.amazonaws.com/FullNode-54424085-4.7.2-output-directory.tgz
# nohup (背景程式執行)
# axel: 這是要執行的命令，通常用於加速文件下載。
# -a: 這是一個選項（也可以稱為參數），它通常用於啟用axel的多線程下載功能，這可以加速文件的下載速度。
# -n 40: 這是另一個選項，它指定了同時使用的下載連接的數量。在這個情況下，設置為40，表示同時使用40個連接下載文件。
  1. 解壓縮FullNode-54424085–4.7.2-output-directory.tgz
nohup tar xvf FullNode-54424085–4.7.2-output-directory.tgz
  1. 解壓縮之後產生一個資料夾(output-directory 內有所有交易資料)
  2. 查詢資料夾的容量是否正確
du -h output-directory #查詢資料夾容量
  1. 將output-directory資料夾移動到java-tron/build/libs底下(若有相同檔名就會一個檔案在移動or取代原本的output-directory資料夾)
  2. 啟動節點同步
nohup java -Xmx24g -XX:+UseConcMarkSweepGC -jar FullNode.jar -c main_net_config.conf -d output-directory
  1. 檢查節點是否在運行
sudo ps aux | grep [F]ullNode

使用api

查詢最新的block數_8090 port & 50545 port
  1. curl http://192.168.200.159:8090/wallet/getnowblock (192.168.200.159 自己的內部網路IP，http不加憑證)
  2. curl -X POST ‘http://192.168.200.159:50545/jsonrpc' — data ‘{“jsonrpc”:”2.0",”method”:”eth_blockNumber”,”params”:[],”id”:64}’
  3. curl -X POST 'http://192.168.200.159:50545/jsonrpc' — data '{“jsonrpc”:”2.0”,”method”:”eth_blockNumber”,”params”:[],”id”:64} '
