下载ectd源码构建

# go is required$ go versiongo version go1.6 darwin/amd64

# GOPATH should be set correctly$ echo $GOPATH/Users/example/go$ mkdir -p $GOPATH/src/github.com/coreos$ cd $GOPATH/src/github.com/coreos$ git clone https://github.com/coreos/etcd.git$ cd etcd$ ./build$ ./bin/etcd

测试安装

$ ./bin/etcdSet a key:$ ETCDCTL_API=3 ./bin/etcdctl put foo barOK
