####setup etcd cluster
在docker-node1上

#下载分布式工具
wget https://github.com/coreos/etcd/releases/download/v3.0.12/etcd-v3.0.12-linux-amd64.tar.gz
#解压
tar zxvf etcd-v3.0.12-linux-amd64.tar.gz
#进入解压文件内
cd etcd-v3.0.12-linux-amd64
#运行下面一大段指令，下面这段运行报错，代码应该是没有问题，应该是网络或者环境问题
nohup ./etcd --name docker-node1 --initial-advertise-peer-urls http://172.31.158.131:2380 \
--listen-peer-urls http://172.31.158.131:2380 \

在docker-node2上

#下载分布式工具

node1现在是这样

```

./etcdctl cluster-health

cluster may be unhealthy: failed to list members

Error: client: etcd cluster is unavailable or misconfigured

error #0: dial tcp 127.0.0.1:4001: getsockopt: connection refused

error #1: dial tcp 127.0.0.1:2379: getsockopt: connection refused

```

node2是这样

```

./etcdctl cluster-health

failed to check the health of member ba28710e7d78116c on http://172.31.158.131:2379: Get http://172.31.158.131:2379/health: dial tcp 172.31.158.131:2379: getsockopt: connection refused

member ba28710e7d78116c is unreachable: [http://172.31.158.131:2379] are all unreachable

member e3cff630f79fce28 is unhealthy: got unhealthy result from http://172.31.158.132:2379

cluster is unhealthy

```
