比特币BTC私有链搭建
下载并安装可执行程序
作者：JKincsdn
1、下载 bitcoind/bitcoin-cli ：BTC 节点服务端/客户端 程序
创建本地目录结构如下 新建目录[devops@wicc-coin bitcoin-regtest]$ pwd
/home/devops/coins/bitcoin-regtest
新建相关文件和子目录
[devops@wicc-coin bitcoin-regtest]$ tree
.
├── bitcoind-cli.sh //客户端查询脚本
├── conf
│ └── bitcoin.conf //节点配置文件
└── run-bitcoin.sh //节点启动脚本
└── data //存放数据的目录，包含debug.log
文件和脚本内容如下
[devops@wicc-coin bitcoin-regtest]$ cat ./bitcoind-cli.sh
#!/bin/bash
#
if [ $# -eq 0 ];then
echo "Error, Usage: $(basename $0) method"
exit 2
fi
bitcoin-cli -rpcport=18443 -rpcuser=wayki -rpcpassword=admin@123 $@
[devops@wicc-coin bitcoin-regtest]$ cat conf/bitcoin.conf
regtest=1
server=1
rpcuser=wayki
rpcpassword=admin@123
rpcallowip=0.0.0.0/0
txindex=1
gen=1
[devops@wicc-coin bitcoin-regtest]$ cat run-bitcoin.sh
#!/bin/bash
basedir=/home/devops/coins/bitcoin-regtest
bitcoind -daemon -conf=$basedir/conf/bitcoin.conf -txindex -rpcbind=0.0.0.0 -datadir=$basedir/data
[devops@wicc-coin bitcoin-regtest]$
配置文件说明
todo
启动节点 运行脚本启动[devops@wicc-coin bitcoin-regtest]$ ./run-bitcoin.sh
Bitcoin server starting
查看log
[devops@wicc-coin regtest]$ tail -f debug.log
2019-12-27T03:49:39Z init message: Starting network threads...
2019-12-27T03:49:39Z addcon thread start
2019-12-27T03:49:39Z dnsseed thread start
2019-12-27T03:49:39Z Loading addresses from DNS seeds (could take a while)
2019-12-27T03:49:39Z 0 addresses found from DNS seeds
2019-12-27T03:49:39Z dnsseed thread exit
2019-12-27T03:49:39Z init message: Done loading
2019-12-27T03:49:39Z net thread start
2019-12-27T03:49:39Z msghand thread start
2019-12-27T03:49:39Z opencon thread start
查看进程和端口是否正常
结果同预想一直，默认私有链regtest的RPC端口号为18443
[devops@wicc-coin bitcoin-regtest]$ ps -ef |grep bitcoind
devops 14744 1 0 12月19 ? 00:59:31 bitcoind -daemon -conf=/home/devops/coins/bitcoin/conf/bitcoin.conf -txindex -rpcbind=0.0.0.0 -datadir=/home/devops/coins/bitcoin/data //测试网
devops 30043 1 0 11:49 ? 00:00:03 bitcoind -daemon -conf=/home/devops/coins/bitcoin-regtest/conf/bitcoin.conf -txindex -rpcbind=0.0.0.0 -datadir=/home/devops/coins/bitcoin-regtest/data
devops 30137 29792 0 12:14 pts/1 00:00:00 grep --color=auto bitcoind //私有链
[devops@wicc-coin bitcoin-regtest]$
[devops@wicc-coin bitcoin-regtest]$ ss -tnl -p |grep 30043 //查看私有链进程监听的端口号
LISTEN 0 128 *:18443 *:* users:(("bitcoind",pid=30043,fd=9)) //RPC端口
LISTEN 0 128 *:18444 *:* users:(("bitcoind",pid=30043,fd=29)) //P2P端口
LISTEN 0 128 :::18444 :::* users:(("bitcoind",pid=30043,fd=27))
[devops@wicc-coin bitcoin-regtest]$

getblockchaininfo查看私有链运行状态等信息，目前区块高度为0，即没有开启挖矿

开启挖矿
1、在配置文件中添加 gen=1 表示节点可以挖矿
[devops@wicc-coin bitcoin-regtest]$ cat conf/bitcoin.conf
regtest=1
server=1
rpcuser=wayki
rpcpassword=admin@123
rpcallowip=0.0.0.0/0
txindex=1
gen=1
[devops@wicc-coin bitcoin-regtest]$
2、由于BTC的共识机制是POW，需要指定矿工，即挖矿的钱给谁，需要新建地址
由于BTC节点 包含 钱包 + 节点，新建的地址私钥默认保存在钱包中
[devops@wicc-coin bitcoin-regtest]$ ./bitcoind-cli.sh getnewaddress //新建地址
2NFKmphFReyaZCn24HE3znqXC2RkfZiowcp
3、挖矿
以下命令表示挖100个块，并将挖矿产出的钱指定给第2步中的地址
[devops@wicc-coin bitcoin-regtest]$ ./bitcoind-cli.sh generatetoaddress 100 2NFKmphFReyaZCn24HE3znqXC2RkfZiowcp

]
4、查询钱包余额
如下查询钱包已经有余额
[devops@wicc-coin bitcoin-regtest]$ ./bitcoind-cli.sh getwalletinfo
{
"walletname": "",
"walletversion": 169900,
"balance": 14949.99998350,
"unconfirmed_balance": 0.00000000,
"immature_balance": 0.00000000,
"txcount": 10100,
"keypoololdest": 1577418579,
"keypoolsize": 999,
"keypoolsize_hd_internal": 1000,
"paytxfee": 0.00000000,
"hdseedid": "2ca1a4d90692fca1af51c907b0aa4e55ce4150db",
"private_keys_enabled": true
}
