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

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

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/
