准备工作
golang环境
etcd地址：https://github.com/etcd-io/etcd
goreman: https://github.com/mattn/goreman
集群搭建
1,安装goreman
# go get github.com/mattn/goreman
2, 创建Procfile文件,一共3个节点，内容如下：
etcd1: etcd--nameinfra1--listen-client-urlshttp://127.0.0.1:12379--advertise-client-urlshttp://127.0.0.1:12379--listen-peer-urlshttp://127.0.0.1:12380--initial-advertise-peer-urlshttp://127.0.0.1:12380--initial-cluster-tokenetcd-cluster-1--initial-cluster'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380'--initial-cluster-statenew--enable-pprof--logger=zap--log-outputs=stderr
etcd2: etcd--nameinfra2--listen-client-urlshttp://127.0.0.1:22379--advertise-client-urlshttp://127.0.0.1:22379--listen-peer-urlshttp://127.0.0.1:22380--initial-advertise-peer-urlshttp://127.0.0.1:22380--initial-cluster-tokenetcd-cluster-1--initial-cluster'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380'--initial-cluster-statenew--enable-pprof--logger=zap--log-outputs=stderr
etcd3: etcd--nameinfra3--listen-client-urlshttp://127.0.0.1:32379--advertise-client-urlshttp://127.0.0.1:32379--listen-peer-urlshttp://127.0.0.1:32380--initial-advertise-peer-urlshttp://127.0.0.1:32380--initial-cluster-tokenetcd-cluster-1--initial-cluster'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380'--initial-cluster-statenew--enable-pprof--logger=zap--log-outputs=stderr
3，启动集群
# goreman -f Procfile start
4, 停止某个节点
# goreman run stop etcd1
5, 启动某个节点
# goreman run restart etcd1
