以太坊公链Geth同步

1、安装所需基础工具

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

2、安装Go

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/profile 
echo 'export PATH=$PATH:$GOROOT/bin' >> /etc/profile 
echo 'export GOPATH=/root/go' >> /etc/profile
echo 'export PATH=$PATH:$GOPATH/bin' >> /etc/profile
source /etc/profile

验证

$ go version
go version go1.10 linux/amd64

3、克隆编译项目go-ethereum

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

在path中加入geth路径

echo 'export PATH=$PATH:/opt/go-ethereum/build/bin' >> /etc/profile
source /etc/profile

验证

[root@iZrj9hk3x36fkle13532jaZ ~]# geth version

4、同步以太坊区块

nohup geth --syncmode "fast" --port "30303" --cache=4096 --datadir /data/geth --rpc --rpcapi db,eth,net,web3,personal,admin,miner --rpcport 8545 --rpcaddr 0.0.0.0 --rpccorsdomain "*"  --maxpeers 999  --maxpendpeers 999 > output.log 2>&1 &

5、进入geth控制台

geth attach ipc:/data/geth/geth.ipc
