安装Golang

go-ethereum 需要go版本不低于 1.7, 文章最后介绍了如何卸载低版本的go

sudo add-apt-repository -y ppa:gophers/archive
sudo apt-get update
sudo apt-get install -y golang-1.10-go

sudo ln -s /usr/lib/go-1.10/bin/go /usr/bin/go 通过软链的方式把go 放到全局环境变量中

查看go版本 go version

编译Ethereum

git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
git checkout v1.8.0
make geth #编译

生成 执行文件 ./build/bin/geth

运行

./build/bin/geth

设定datadir 并后台运行

nohup ./build/bin/geth --datadir /mnt/eth &

##移动 geth
sudo mv ./build/bin/geth /usr/local/bin/

同步方式

eth有三种同步方式:

--syncmode 'fast'   Blockchain sync mode ('fast' 'full or 'light')

默认是 fast, 如果同步全部数据 geth --syncmode full

##守护进程

geth Ethereum node to run automatically on Ubuntu

#/etc/supervisor/conf.d/gethd.conf

[program:gethd]
command=/usr/local/bin/geth --datadir /mnt/eth/data --syncmode full --rpc
user=deployer # deployer用户启动任务
autostart=true
autorestart=true
stderr_logfile=/mnt/eth/data/geth_err.log
stdout_logfile=/mnt/eth/data/geth.log

sudo supervisorctl reload

卸载Golang

sudo apt-get remove golang-go
sudo apt-get remove --auto-remove golang-go
