centos7 以太坊環境搭建
1、yum update -y && yum install git wget bzip2 vim gcc-c++ ntp epel-release nodejs cmake -y
2、yum install epel
3、yum install golang
4、cd /usr/local/
git clone https://github.com/ethereum/go-ethereum.git
cd go-ethereum
make all
5、echo "export PATH=$PATH:/usr/local/go-ethereum/build/bin" >> /etc/profile
6、source /etc/profile
7、cmake 安裝
cd /tmp/&& wget https://cmake.org/files/v3.9/cmake-3.9.2.tar.gz
tar xzvf cmake-3.9.2.tar.gz
cd cmaker-3.9.2
./bootstrap && make && make install
8、mkdir /data/{ethbase,genesis}
9、touch /data/genesis/gensis.json
