GXChain 2.0 节点安装

环境要求

  • 系统: Ubuntu 14.04 LTS 64-bit, 4.4.0-63-generic 内核或更高
  • 内存: 8GB+
  • 硬盘: 100GB+

GXChain 依赖安装：

apt-get install  ntp software-properties-common
add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update
apt-get install libstdc++-7-dev

节点安装

以下的步骤演示的是主网节点的启动

1. 下载Release包

wget http://gxb-package.oss-cn-hangzhou.aliyuncs.com/gxb-core/gxb_ubuntu_1.0.180820.beta.tar.gz -O gxb_ubuntu_1.0.180820.beta.tar.gz
tar zxvf gxb_ubuntu_1.0.180820.beta.tar.gz

2. 启动节点

# 同步节点启动命令
./programs/witness_node/witness_node --data-dir=trusted_node --rpc-endpoint="127.0.0.1:28090" &

根据上面的步骤:

  • 启动了一个节点监听在 127.0.0.1:28090
  • 指定了区块信息保存在 ./trusted_node 目录下

友情提示

  • 同步区块大约需要 10+个小时
  • 如果是节点升级，程序会自动判断是否需要replay区块

3. 查看日志

tail -f trusted_node/logs/witness.log

节点同步过程后，日志看起来是这样的:
