二涌矢、搭建以太坊私鏈及客戶端基本操作

1掖举、搭建私有鏈，創(chuàng)建自己的創(chuàng)始區(qū)塊

建立私鏈根目錄

$makedir geth-private-chain
$cd get-private-chain

創(chuàng)始區(qū)塊的配置寫在json文件中娜庇，我們需要將下面文件的內(nèi)容保存為一個json文件
ps:下面所有操作的根目錄都為： get-private-chain

{
      "config": {
        "chainId": 10, 
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
      },
   "alloc"   : {},
   "coinbase"  : "0x0000000000000000000000000000000000000000",
   "difficulty" : "0x20000",
   "extraData" : "",
   "gasLimit"  : "0x2fefd8",
   "nonce"   : "0x0000000000000042",
   "mixhash"  :"0x0000000000000000000000000000000000000000000000000000000000000000",
   "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
   "timestamp" : "0x00"
}

KEY
mixhash	與nonce配合用于挖礦塔次，由上一個區(qū)塊的一部分生成的hash。注意他和nonce的設(shè)置需要滿足以太坊的Yellow paper, 4.3.4. Block Header Validity, (44)章節(jié)所描述的條件思灌。
nonce	nonce就是一個64位隨機數(shù)俺叭，用于挖礦恭取，注意他和mixhash的設(shè)置需要滿足以太坊的Yellow paper, 4.3.4. Block Header Validity, (44)章節(jié)所描述的條件泰偿。
difficulty	設(shè)置當前區(qū)塊的難度，如果難度過大蜈垮，cpu挖礦就很難耗跛，這里設(shè)置較小難度
alloc	用來預置賬號以及賬號的以太幣數(shù)量，因為私有鏈挖礦比較容易攒发，所以我們不需要預置有幣的賬號调塌，需要的時候自己創(chuàng)建即可以。
coinbase	礦工的賬號惠猿，隨便填
timestamp	設(shè)置創(chuàng)世塊的時間戳
parentHash	上一個區(qū)塊的hash值羔砾，因為是創(chuàng)世塊，所以這個值是0
extraData	附加信息偶妖，隨便填姜凄，可以填你的個性信息
gasLimit	該值設(shè)置對GAS的消耗總量限制，用來限制區(qū)塊能包含的交易信息總和趾访，因為我們是私有鏈态秧，所以填最大。

此文件可以從官網(wǎng)直接復制扼鞋，原始的chainId為0申鱼，但有可能在部署合約時出現(xiàn)問題愤诱，建議修改為10或其他數(shù)字

建立存放區(qū)塊數(shù)據(jù)的目錄

$makedir data0

目錄結(jié)構(gòu)為

geth-private-chain
|-----data0
|-----genesis.json

$ ls
data0       genesis.json

初始化以太坊私鏈數(shù)據(jù)

$ geth init genesis.json --datadir data0

geth是命令，init是命令選項捐友，genesis.json 是init的參數(shù)淫半，表示按照配置文件進行初始化。--datadir data0楚殿，指定區(qū)塊鏈的數(shù)據(jù)存放目錄為data0撮慨。

運行命令，執(zhí)行的結(jié)果如下脆粥，表示初始化成功：

INFO [03-12|14:36:52] Successfully wrote genesis state database=lightchaindata              hash=5e1fc7…d790e0

初始化成功后砌溺，會生成如下的目錄結(jié)構(gòu)

新建賬戶猖闪，兩種方式

PS：只是創(chuàng)建了賬戶肌厨，還未經(jīng)過任何交易或挖礦獎勵培慌，因此這里每個賬戶的比特幣數(shù)量都是0，

要使交易被處理，必須挖礦哼审，獲得新的區(qū)塊記錄交易數(shù)據(jù)谐腰。
