etcd cluster id mistmatch

我在做etcd 群集搭建，共三个几点，我使用同一台机器的不同的端口可以搭建成功，但用三台机器搭建时启动服务后报错'cluster ID mismatch'，这三台都是云主机，相应的端口都已经开放了，可以互相访问， 详细报错日志如下：

启动命令:

systemctl daemon-reload
systemctl enable etcd
systemctl start etcd

我尝试删除data-dir文件夹，然后重建，重启服务，还是无效

帮我看下我哪里出错了

etcd version is 3.3.18

system is ubuntu 16.04
