[网络协议]heco（火币生态链）主网链部署

一.前期准备

1.1 部署文档信息：

heco官网：https://www.hecochain.com/zh-cn/
heco链github地址：https://github.com/HuobiGroup/huobi-eco-chain/releases
主网区块链浏览器：https://hecoinfo.com/
主网链官方部署文档：https://docs.hecochain.com/#/dev/install
heco主网相关信息：https://docs.hecochain.com/#/mainnet
手续费（gasprice）：https://tc.hecochain.com/price/prediction
创世文件介绍：https://docs.hecochain.com/#/genesis
开发者文档：https://docs.hecochain.com/#/

1.2 硬件配置信息

最低

8core
16g
硬盘空间 > 500 GB
带宽2M

推荐

16core
32g
硬盘空间 > 500 GB
带宽30M

1.3 网络配置信息

一个公网ip
开启 TCP/UDP 32668 端口；便于 p2p 发现和互联
rpc端口：8545

二.heco主链镜像生成

下载heco主链基础镜像

docker pull buildpack-deps:jessie-curl

编写Dockerfile

# vim Dockerfile 

FROM buildpack-deps:jessie-curl
RUN wget -P /usr/local/bin/ https://github.com/HuobiGroup/huobi-eco-chain/releases/download/v1.0.0/geth-linux-amd64 && mv /usr/local/bin/geth-linux-amd64 /usr/local/bin/geth && chmod +x /usr/local/bin/geth
EXPOSE 8545 8546 30303 30303/udp 
WORKDIR /data
ENTRYPOINT ["geth"]

生成heco主链镜像

docker build . -t huobi-eco:v1.0.0

注：需要在与Dockerfile同一级目录下执行此命令

三.heco主链容器生成

3.1 编辑heco主网配置文件

下载heco主网的config.toml（配置文件）

# cd /opt/docker/heco/

[Eth]
SyncMode = "full"
DiscoveryURLs = []
TrieCleanCacheRejournal= 300000000000

[Eth.Miner]
GasFloor = 8000000
GasCeil = 8000000
GasPrice = 0
Recommit = 3000000000
Noverify = false

[Eth.Ethash]
CacheDir = "ethash"
CachesInMem = 2
CachesOnDisk = 3
CachesLockMmap = false
DatasetDir = "/data/heco/data/.ethash"
DatasetsInMem = 1
DatasetsOnDisk = 2
DatasetsLockMmap = false
PowMode = 0

[Eth.TxPool]
Locals = []
NoLocals = false
Journal = "transactions.rlp"
Rejournal = 3600000000000
PriceLimit = 1
PriceBump = 10
AccountSlots = 16
GlobalSlots = 4096
AccountQueue = 64
GlobalQueue = 1024
Lifetime = 10800000000000

[Node]
DataDir = "/data/heco/data"
InsecureUnlockAllowed = true
NoUSB = true
IPCPath = "geth.ipc"
HTTPHost = "0.0.0.0"
HTTPPort = 8545
HTTPCors = ["*"]
HTTPVirtualHosts = ["*"]
HTTPModules = ['eth', 'net', 'web3']

WSHost = "0.0.0.0"
WSPort = 8546
WSModules = ['eth', 'net', 'web3']

GraphQLVirtualHosts = ["localhost"]


[Node.P2P]
MaxPeers = 50
NoDiscovery = false

ListenAddr = ":32668"
EnableMsgEvents = false

[Node.HTTPTimeouts]
ReadTimeout = 30000000000
WriteTimeout = 30000000000
IdleTimeout = 120000000000

注：关键配置详解

HTTPHost：HTTP-RPC服务连接白名单，此参数的值默认为 “localhost”，仅允许本地可访问，可设置为：“0.0.0.0”

HTTPVirtualHosts：HTTP-RPC服务监听接口,此参数的值默认为 [“localhost”],可设置为：HTTPVirtualHosts = ["*"]

以上文件默认使用了全节点同步，如果需要使用fast模式，将下列配置：

SyncMode = "full"
修改为
SyncMode = "fast"

3.2 启动heco主网链

启动参数完整帮助信息，可通过命令 geth help 或 geth -h 进行查阅。

docker run -itd --restart=unless-stopped -v /etc/localtime:/etc/localtime -v /etc/timezone:/etc/timezone --name public_heco -v $(pwd):/data -p 32668:32668 -p 8545:8545 huobi-eco:v1.0.0 --config /data/config.toml --logpath /data/logs

注：配置参数详解：

–config：指定配置文件路径

–logpath：指定日志文件路径，若不指定，日志将输出到heco控制台

–verbosity：日志级别（0=silent, 1=error, 2=warn, 3=info, 4=debug, 5=detail）

如果需要启用archive 类型，需要加入以下两个启动参数：

使用 --syncmode=full --gcmode=archive 模式，即归档节点，这种模式保存了最最最全的节点数据，占用硬盘空间也会更大。（后面会专门针对节点数据配置写一篇文档）

--syncmode full 
--gcmode archive

–testnet：节点未指定网络标识时，默认连接heco主网；若需要连接heco测试网，启动时需加入此参数:

四.查看heco主网链是否部署成功

4.1 查看heco容器是否成功启动

# docker ps

4.2 查看heco主网节点启动日志是否正常

五.查看heco主网节点是否同步完成

查看节点区块数据同步进度
查看节点当前同步的同步进度，返回为false，则heco主网节点区块数据同步完成

# curl -s -H Content-Type:application/json -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://127.0.0.1:8545
{"jsonrpc":"2.0","id":1,"result":{"currentBlock":"0x11a6db","highestBlock":"0x500bfe","knownStates":"0x0","pulledStates":"0x0","startingBlock":"0x0"}}

查看节点最新区块号

查看节点当前同步的最新区块号，与heco官方区块链浏览器进行对比，查看是否一致，是否已与公网节点的区块一致

heco官方主网浏览器：https://hecoinfo.com/

# curl -s -H Content-Type:application/json -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://127.0.0.1:8545
{"jsonrpc":"2.0","id":1,"result":"0x11d8a0"}

查询heco链上最新的交易哈希，确认是否可获取交易信息，如果可获取，说明已同步区块信息

# curl -H Content-Type:application/json -X POST --data '{"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["0xab943f0a9c41f1b931bd1f95dd6776559ef689144aa792478d5952c62611513d"],"id":1}' http://127.0.0.1:5545
{"jsonrpc":"2.0","id":1,"result":{"blockHash":"0xa511f1cb62d9ab1c6c28584a4e476a463b0b7183136519b226d5ed873bf55fa7","blockNumber":"0x11fd4c","from":"0x6f7059179b93c88b961cc279deee898ff7e93faa","gas":"0xf4240","gasPrice":"0x3b9aca00","hash":"0xab943f0a9c41f1b931bd1f95dd6776559ef689144aa792478d5952c62611513d","input":"0x22c90166","nonce":"0x6864","to":"0x81fbaaacd63b423d71de99b95a654c0526bfdc69","transactionIndex":"0x10","value":"0x0","v":"0x123","r":"0x79bc2ab27f5588f7b7129cffe9786a92a974d41775ddbf8ffe8ca316894628c3","s":"0x37df2240af75fbe48917ae583d39437619e8ec3ec5d444fb30ee486207193f02"}}
