以太坊centos6.5搭建私有链创建账户、挖矿、转账

1.系统配置 cat /etc/redhat-release

2.安装golang
Golang官网下载地址：https://golang.org/dl/
将安装包下载到任意目录下（/app/ETH/golang）
a.wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
b.tar -zxvf go1.10.3.linux-amd64.tar.gz
c.添加/app/ETH/golang/go/bin目录到PATH变量中。添加到/etc/profile

d.source /etc/profile
e.go version

3.下载以太坊代码
https://github.com/ethereum/go-ethereum/releases
我下的是go-ethereum-1.8.1.tar.gz
tar -zxvf go-ethereum-1.8.1.tar.gz
4.编译以太坊代码
进入/home/ETH/go-ethereum-1.8.1
make

生成build/bin文件夹 geth文件

5.创世区块文件init.json

{ 
  "config": { 
    "chainId": 10, 
    "homesteadBlock": 0, 
    "eip155Block": 0, 
    "eip158Block": 0 
  }, 
  "coinbase"   : "0x0000000000000000000000000000000000000000", 
  "difficulty" : "0x20000", 
  "extraData"  : "", 
  "gasLimit"   : "0xffffffff", 
  "nonce"      : "0x0000000000000042", 
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000", 
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000", 
  "timestamp"  : "0x00", 
  "alloc"      : {} 
} 

6.创世区块初始化

./geth  --datadir "/app/chain" init init.json 

7.启动以太坊

./geth --rpc --rpccorsdomain "*" --datadir "/app/chain" --port "30303" --rpcapi "db,eth,net,web3" --networkid 100000 console 

8.账户查看 eth.accounts

9.创建账户personal.newAccount() 输入两遍密码“123456”

10.获取账户资产eth.getBalance(eth.accounts[0])

11.开始挖矿miner.start()

12.转账

 eth.sendTransaction({from: '0x0bb81ec0920fed869f6b5f1bf46d4b923058af18', to: '0xa695bc0b0500834a627f07ad4e364105802cb5d2', value: web3.toWei(1, "ether")}) 

需要先解锁转出账户

personal.unlockAccount("0x0bb81ec0920fed869f6b5f1bf46d4b923058af18","123456")//账号，密码 

挖矿成功，转账才能成功
