多主机搭建etcd集群

下载https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz分别放到两台主机上，因为wget太慢了。

HOST1：101.200.243.176（公网）172.17.229.160（内网）
HOST2：110.43.50.186（公网）10.0.0.254（内网）

HOST1

[root@peiqi test]# tar xzvf etcd-v3.4.10-linux-amd64.tar.gz
[root@peiqi test]# mv etcd-v3.4.10-linux-amd64 etcd && cd etcd
