以太坊公链私链geth同步

1、安装必备环境插件 #1-5 公有链 +6-10 私有链

yum update -y && yum install git wget bzip2 vim gcc-c++ ntp epel-release nodejs cmake -y
yum install -y curl git golang nodejs gcc-c++

2、安装go语言

wget https://dl.google.com/go/go1.10.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.10.linux-amd64.tar.gz
echo 'export GOROOT=/usr/local/go' >> /etc/bashrc 
echo 'export PATH=$PATH:$GOROOT/bin' >> /etc/bashrc  
echo 'export GOPATH=/root/go' >> /etc/bashrc
echo 'export PATH=$PATH:$GOPATH/bin' >> /etc/bashrc
source /etc/bashrc

3、验证go语言安装成功

[root@jubeiTest root]# go version
go version go1.10 linux/amd64

4、安装geth客户端 '我的路径'=/mnt/

git clone https://github.com/ethereum/go-ethereum.git  
cd go-ethereum  
make all
echo 'export PATH=$PATH:/’你的路径’/go-ethereum/build/bin' >> /etc/bashrc
source /etc/bashrc

5、验证geth

[root@jubeiTest go-ethereum]# geth version
Geth
Version: 1.8.18-unstable
Git Commit: 1ff152f3a43e4adf030ac61eb5d8da345554fc5a
Architecture: amd64
Protocol Versions: [63 62]
Network Id: 1
Go Version: go1.10
Operating System: linux
GOPATH=/root/go
GOROOT=/usr/local/go

6、智能合约

cd ~
wget https://cmake.org/files/v3.9/cmake-3.9.2.tar.gz  
tar xvf cmake-3.9.2.tar.gz && cd cmake-3.9.2
./configure && make && make install
pwd
/home/ddp/cmake-3.9.2

cd /mnt/
mkdir geth_data
touch start.sh
chmod 755 start.sh
vim start.sh
(nohup geth --syncmode "fast" --cache=512 --datadir "/mnt/geth_data/data0" --rpc --rpcapi db,net,eth,web3,personal --rpcaddr 0.0.0.0 --rpccorsdomain "*" 2>>geth_log &)
sh start.sh
cd geth_data
geth attach ./geth.ipc
eth.syncing

同步节点

 >eth.syncing
{
  currentBlock: 164096,
  highestBlock: 6841125,
  knownStates: 318087,
  pulledStates: 307252,
  startingBlock: 0
}

7、创建创世文件（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"
}

8、初始化创世文件

$ geth --datadir ‘你的路径’ init ‘你的路径’/genesis.json

9、创建start.sh脚本

(nohup geth --syncmode "fast" --cache=512 --datadir "/mnt/geth_data/data0" --rpc --rpcapi db,net,eth,web3,personal --rpcaddr 0.0.0.0 --rpccorsdomain "*" 2>>geth_log &)

10、进入控制台

$cd ‘你的路径’
$ geth attach ./geth.ipc
同步命令eth.syncing

history命令

     yum update -y && yum install git wget bzip2 vim gcc-c++ ntp epel-release nodejs cmake -y
     wget https://dl.google.com/go/go1.10.linux-amd64.tar.gz
     tar -C /usr/local -xzf go1.10.linux-amd64.tar.gz
     echo 'export GOROOT=/usr/local/go' >> /etc/bashrc
     echo 'export PATH=$PATH:$GOROOT/bin' >> /etc/bashrc
     echo 'export GOPATH=/root/go' >> /etc/bashrc
     echo 'export PATH=$PATH:$GOPATH/bin' >> /etc/bashrc
     source /etc/bashrc
     go version
     cd /mnt/
     git clone https://github.com/ethereum/go-ethereum.git
     cd go-ethereum/
     make all
     echo 'export PATH=$PATH:/mnt/go-ethereum/build/bin' >> /etc/bashrc
     source /etc/bashrc
     cd /mnt/
     mkdir
     mkdir geth_data
     cd geth_data/
