API服务器部署
本文档介绍如何部署一个GXChain的API服务器。
1. 环境要求
- 系统: macOS / Ubuntu 14.04 64-bit, 4.4.0-63-generic 以上内核
- 内存: 16GB+
- 硬盘: 100GB+
- 网络：10MB+带宽, 有公网独立IP
依赖安装
- 安装ntp
sudo apt-get install ntp
# macOS安装ntp: brew install ntp
- 安装libstdc++-7-dev
# Ubuntu系统需要安装, macOS不需要
apt-get update
apt-get install software-properties-common
add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update
apt-get install libstdc++-7-dev
2. 下载Release包
# 执行这个shell脚本，会自动从github下载最新的主网程序，并解压至当前目录下
curl 'https://raw.githubusercontent.com/gxchain/gxb-core/dev_master/script/gxchain_install.sh' | bash
3. 启动节点程序，同步数据
export LC_ALL=C
./programs/witness_node/witness_node --data-dir=trusted_node --rpc-endpoint="0.0.0.0:28090" --p2p-endpoint="0.0.0.0:6789" &
根据上面的步骤:
- 指定区块信息保存在
./trusted_node目录下 - 启动一个监听端口为28090的RPC服务，开启了API服务, 可以给钱包客户端提供RPC调用
- 启动一个监听端口为6789的P2P服务，可以作为seed node为网络中的其它节点提供连接和区块同步服务
友情提示
- 同步区块大约需要 30+小时, 当然这和你的网络情况有一定关系
4. 查看日志
tail -f trusted_node/logs/witness.log
区块同步过程中，每隔1000个区块会打印一行日志； 同步到最新区块时，每3秒打印一行日志，区块号连续，日志看起来是这样的:

5. 测试API服务是否可用
假设你的公网IP地址为x.x.x.x， 调用节点的get_dynamic_global_properties API查看最新区块号：
curl POST --data '{ "jsonrpc": "2.0", "method": "call", "params": [0, "get_dynamic_global_properties", []], "id": 1 }' http://x.x.x.x:28090
