centos 下安装以太坊--简单的挖矿

一、下载以太坊源码

    wget http://www.huiyanghua.com/js/go-ethereum-1.4.12.zip

二、解压

tar -zxvf go-ethereum-1.4.12.zip /usr/local/bin

 三、建立私有文件夹 mkdir private-geth

四、进入私有文件夹

    cd private-geth

五、创世纪区块文件

vim genesis.json

{     "config": {         "chainId": 15,         "homesteadBlock": 0,         "eip155Block": 0,         "eip158Block": 0     },     "coinbase" : "0x0000000000000000000000000000000000000000",     "difficulty" : "0x40000",     "extraData" : "",     "gasLimit" : "0xffffffff",     "nonce" : "0x0000000000000042",     "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",     "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",     "timestamp" : "0x00",     "alloc": { } }

六、初始化创世纪节点,并设置data目录:

/usr/local/bin/geth/geth  --datadir ./data/00 init genesis.json(红色部分表示geth的安装目录)

能够看到在当前目录下新增了一个文件夹data，目录结构以下

启动节点, 加上console 表示启动后,启用命令行:

 /usr/local/bin/geth/geth --datadir ./data/00 --networkid 1234567890 console

如今私有网络就搭建成功

 

挖矿

 

挖矿首先必须有一个帐户,输入下面的命令,查看当前node中的全部帐户:

> eth.accounts []

 

> personal.newAccount('oracle') "0xb241b0b47a4d773d5c8b462607f590f3ed1762c8" > INFO [09-16|02:54:18] New wallet appeared                      url=keystore:///data/00/keystore/UT… status=Locked > eth.accounts ["0xb241b0b47a4d773d5c8b462607f590f3ed1762c8"]

挖矿首先必须有一个帐户,输入下面的命令,查看当前node中的全部帐户:

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

> eth.accounts [] ###输出了一个"[]",说明毛都么有一根,更别说帐户了.既然没有,那就来建立一个,继续输入命令: > personal.newAccount("123456") ###正常状况,命令行会输出: INFO [05-15|23:59:29] New wallet appeared                      url=keystore:///home/zl/Documents/p… status=Locked "0x5b901c2495c077f515ae84fc53206f2eb3bf8296" ###再用以前查看帐户的命令看看: > eth.accounts ["0x5b901c2495c077f515ae84fc53206f2eb3bf8296"] ###有输出了"0x5b.......96"这一串就是帐户的地址. ###帐户有了,接下来作点更有意思的事,开始挖矿....继续在命令行书输出: > miner.start() INFO [05-16|00:07:25] Updated mining threads                   threads=0 INFO [05-16|00:07:25] Starting mining operation null INFO [05-16|00:07:25] Commit new mining work                   number=1 txs=0 uncles=0 elapsed=38.053ms INFO [05-16|00:07:28] Generating DAG in progress               epoch=0 percentage=0 elapsed=1.715 INFO [05-16|00:07:30] Generating DAG in progress               epoch=0 percentage=1 elapsed=3.448s INFO [05-16|00:07:31] Generating DAG in progress               epoch=0 percentage=2 elapsed=5.059s INFO [05-16|00:07:33] Generating DAG in progress               epoch=0 percentage=3 elapsed=6.799s INFO [05-16|00:07:35] Generating DAG in progress               epoch=0 percentage=4 elapsed=8.373s ...................................这个percenage=100,也就是100%之后.,就不断的出现下面的提示.............
