以太坊搭建私鏈錢包查詢交易等

centos 7以上安裝私鏈

1.安裝golang

國內鏡像：https://studygolang.com/dl

安裝golang 1.14以上版本，否則在按照geth 時會卡主不動

golang 安裝

#cd /usr
#wget https://studygolang.com/dl/golang/go1.14.4.linux-amd64.tar.gz
# tar -C /root -xzf go1.14.3.linux-amd64.tar.gz
# cd /root; vi /etc/profile
export GOPATH=/root/Go
export GOROOT=/root/go
export PATH=$PATH:$GOROOT/bin
# source /etc/profile
# go version
go version go1.14.3 linux/amd64

2.安裝golang 版本的以太坊客戶端geth

github 上面地址下載不下來

cd /usr
git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
make geth

使用國內碼雲代碼

cd /mnt
git clone https://gitee.com/mirrors/go-ethereum
cd go-ethereum
make geth

如按照卡主不動，檢查go version 是否版本1.14以上

配置環境變量

vi /etc/profile
export ETH_HOME=/mnt/go-ethereum/build
export PATH=$PATH:$ETH_HOME/bin
source /etc/profile

3.初始化創世文件

1.配置創世文件genesis.json

創建創世文件

cd /mnt 
vi genesis.json

{
  "config": {
        "chainId": 15,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x20000",
  "extraData"  : "",
  "gasLimit"   : "0x2fefd8",
  "nonce"      : "0x0000000000001993",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "timestamp"  : "0x00"
}

2.初始化創建創世文件夾

cd /mnt
./geth  --datadir "/mnt/geth_data/prod1" init genesis.json

3.開始區塊同步

nohup geth --syncmode "fast" --cache=512 --maxpeers 50 --datadir "/mnt/geth_data/prod1" --rpc --rpcport 8545 --rpcapi db,net,eth,web3,personal --rpcaddr 0.0.0.0 --rpccorsdomain "*" 2>>geth_log &

4.進入geth

cd /mnt/geth_data/prod1
geth attach geth.ipc 

5.查看命令

# 查看區塊同步情況
eth.syning

#查看block高度
eth.blockNumber

# 查看當前私鏈上錢包地址
eth.accounts
