前期准备  
Git  
sudo yum install -y git  
Go

参考官档：[https://golang.org/doc/install][https_golang.org_doc_install]

Geth

参考官档：[https://ethereum.github.io/go-ethereum/install/][https_ethereum.github.io_go-ethereum_install]

git clone https://github.com/ethereum/go-ethereum
    cd go-ethereum/
    make geth
    #测试是否安装正确
    build/bin/geth version

搭建私有链

1.  准备创世区块配置文件

{ 
      "config": { 
        "chainId": 666,
        "homesteadBlock": 0,
        "eip150Block": 0,
        "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",

        "petersburgBlock": 0,
        "istanbulBlock": 0,
        "ethash": { }
      },
      "nonce": "0x0",
      "timestamp": "0x5ddf8f3e",
      "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000",
      "gasLimit": "0x47b760",
      "difficulty": "0x00002",
      "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
      "coinbase": "0x0000000000000000000000000000000000000000",
      "alloc": { 
         "e5E6736946fB5459c95c50Ee41F0724892090779": { 
            "balance": "1000000000000000000000000000"
          }
      },
      "number": "0x0",
      "gasUsed": "0x0",
      "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
    }

back

{ 
      "config": { 
            "chainId": 424,
            "homesteadBlock": 0,
            "eip155Block": 0,
            "eip158Block": 0
        },
      "alloc"      : { },
      "coinbase"   : "0x0000000000000000000000000000000000000000",
      "difficulty" : "0x2",
      "extraData"  : "",
      "gasLimit"   : "0x2fefd8",
      "nonce"      : "0x0000000000000042",
      "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
      "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
      "timestamp"  : "0x00"
    }

1.  初始化：写入创世区块  
    目录结构：

eta-test
    ├── data
    └── customGenesis.json

初始化：

cd etc-test
    geth --datadir data init customGenesis.json

初始化成功：

INFO [09-27|02:11:00.035] Maximum peer count                       ETH=25 LES=0 total=25
    INFO [09-27|02:11:00.036] Allocated cache and file handles         database=/data1/eth-test/edata/geth/chaindata cache=16 handles=16
    INFO [09-27|02:11:00.037] Writing custom genesis block

    INFO [09-27|02:11:00.038] Successfully wrote genesis state         database=chaindata                            hash=40c510…7253cf
    INFO [09-27|02:11:00.038] Allocated cache and file handles         database=/data1/eth-test/edata/geth/lightchaindata cache=16 handles=16

成功后目录结构：

eta-test
    ├── data
    │   ├── geth
    │   │   └── chaindata
    │   │       ├── 000002.log
    │   │       ├── CURRENT
    │   │       ├── LOCK
    │   │       ├── LOG
    │   │       └── MANIFEST-000003
    │   └── keystore
    └── customGenesis.json

1.  启动私有链节点  
    启动节点并进入交互式控制台

geth --rpc --rpcport "8545" --datadir /mnt/eth-test/data --allow-insecure-unlock --port "30303" --networkid 424 console

或

./bin/geth -rpc -rpcaddr 0.0.0.0 -rpcport 58545 -rpcapi personal,db,eth,net,web3,admin --datadir ethdata/ --allow-insecure-unlock -syncmode fast -maxpeers 100 -cache 1024

1.  创建账户  
    前面只是搭建了私有链，并没有自己的账户，可以在js console中输入eth.accounts来验证

eth.accounts
    []
     
    #创建账户,两种方式
    personal.newAccount()
    Passphrase: 
    Repeat passphrase: 
    "0x94a5e2b161d2897f6e917a1011d0fdb8cc665662"
     
     
    personal.newAccount("123456")
    "0xb085911023c62e7756124affbd20ddf295adcf63"
     
    eth.accounts
    ["0xb085911023c62e7756124affbd20ddf295adcf63", "0x94a5e2b161d2897f6e917a1011d0fdb8cc665662"]

1.  查看账户余额

> eth.getBalance(eth.accounts[0])
    0
    > eth.getBalance(eth.accounts[1])
    0

6.启动&停止挖矿  
\#开始挖矿，参数表示线程数

miner.start(1)

\#停止挖矿

miner.stop()

\#默认情况下coinbase是本地账户中的第一个账户

eth.coinbase
    "0xb085911023c62e7756124affbd20ddf295adcf63"

\#修改coinbase

miner.setEtherbase(eth.accounts[1])

\#查看余额

> eth.getBalance(eth.accounts[0])
    50000000000000000000
    > eth.getBalance(eth.accounts[1])
    0

7.发送交易  
\#解锁账户

> personal.unlockAccount(eth.accounts[0])
    Unlock account 0xb085911023c62e7756124affbd20ddf295adcf63
    Passphrase: 
    true

\#发送交易

> eth.sendTransaction({ from: eth.accounts[0], to: eth.accounts[1], value: web3.toWei(10, "ether")})
    INFO [09-27|10:02:47.375] Setting new local account                address=0xB085911023C62e7756124AffBD20ddf295adCF63
    INFO [09-27|10:02:47.375] Submitted transaction                    fullhash=0x0e2adfa24216ce46123939fc91b17c361e22e0fda48cc62fab6cc5ef0e30bc97 recipient=0x94A5e2B161d2897F6E917A1011D0Fdb8cc665662
    "0x0e2adfa24216ce46123939fc91b17c361e22e0fda48cc62fab6cc5ef0e30bc97"

\#查看交易池中的状态，目前有一个交易未被确认

> txpool.status
    { 
      pending: 1,
      queued: 0
    }

\#开始挖矿

miner.start(1);admin.sleepBlocks(1);miner.stop();

\#查看交易池中的状态，刚才的交易被确认

> txpool.status
    { 
      pending: 0,
      queued: 0
    }
    8.查看交易和区块
    #查看区块数量
    > eth.blockNumber
    12

#查看具体区块
    > eth.getBlock(11)

9.连接到其他节点  
在节点2上，重复步骤1和3，但是要注意rpcport和port参数要与节点1不同（最好数据文件夹也不同）。在节点1上执行

\#127.0.0.1替换成节点1的IP

> admin.nodeInfo.enode
    "enode://46de08fc64222512dd120f3876aa6d9947fd7e045e5a09bf95e90fcf3984d600dc25dc06cbb04e72b175bf23031ffb65adecf275dae229e69e3e32c67b5deec6@127.0.0.1:30303?discport=0"

在节点2执行：

\#注意多了bootnodes参数

geth --rpc --rpcport "8546" --datadir /data1/eth-test/edata --port "30304" --networkid 424 --bootnodes "enode://46de08fc64222512dd120f3876aa6d9947fd7e045e5a09bf95e90fcf3984d600dc25dc06cbb04e72b175bf23031ffb65adecf275dae229e69e3e32c67b5deec6@127.0.0.1:30303" console

    INFO [09-27|02:15:44.861] Fast sync complete, auto disabling

\#也可以不加bootnodes参数，启动后调用命令添加节点  
admin.addPeer(“enode://46de08fc64222512dd120f3876aa6d9947fd7e045e5a09bf95e90fcf3984d600dc25dc06cbb04e72b175bf23031ffb65adecf275dae229e69e3e32c67b5deec6@127.0.0.1:30303”)
