etcd cluster id mistmatch

[peachestao]

I am building an etcd cluster of three nodes. If the three nodes are on the same machine（use different port）, it is normal. If the three nodes are on different machines（the three machines can access each other）, an error is reported: 'cluster ID mismatch',The detailed log is as follows：

start command:

systemctl daemon-reload
systemctl enable etcd
systemctl start etcd

I tried to delete the data-dir and rebuild it ,then restart the etcd service, but it still didn't work

Please help me, what's wrong with me

etcd version is 3.3.18

system is ubuntu 16.04
