btcd 搭建 测试网 testnet

安装go

# go version
go version go1.21.0 linux/amd64

# go env GOROOT GOPATH
/usr/local/go
/root/go

# vim .bashrc
export PATH=$PATH:/usr/local/go/bin
export GOPATH=/root/go
export PATH=$PATH:/root/go/bin

# source .bashrc
# echo $GOPATH
/root/go

git clone https://github.com/btcsuite/btcd $GOPATH/src/github.com/btcsuite/btcd

# cd $GOPATH/src/github.com/btcsuite/btcd
# GO111MODULE=on go install -v . ./cmd/...

# btcd --version
btcd version 0.23.3-beta

cd /nvme2n1/
mkdir btcd
mkdir btcd/btcd-data
cd btcd/

# vim btcd.conf
[Application Options]
testnet=1
rpcuser=test
rpcpass=test@0908
datadir=/nvme2n1/btcd/btcd-data

# cat btcd.sh
#!/bin/bash

nohup btcd --configfile=/nvme2n1/btcd/btcd.conf >> /nvme2n1/btcd/btcd.log 2>&1 &

• 参考 JSON-RPC API 使用 getblockcount 检索当前区块高度

go get github.com/btcsuite/btcd/btcutil
go get github.com/btcsuite/btcd/rpcclient

# go run .
2023/09/08 16:50:06 Block count: 484510

获取区块高度

# go run .
2023/09/08 17:09:14 open /root/.btcd/rpc.cert: no such file or directory
exit status 1

• 运行 btcd 会生成rpc.cert然后终止运行

btcd

运行 btcd.go

cd $GOPATH/src
mkdir btcd
cd btcd/
vim btcd.go

• 修改用户名和密码

	connCfg := &rpcclient.ConnConfig{
    
    
		Host:         "localhost:18334",
		Endpoint:     "ws",
		User:         "test",
		Pass:         "test@0909",
		Certificates: certs,
	}

go mod init example/btcd
