目前在學習K8S, etcd 集群搭建，啟動時候報錯：

檢查啟動service 和配置etcd.conf ,問題應該沒有出在配置上。

解決辦法：刪除了etcd集群所有節點中的--data_dir的內容
分析： 因為集群搭建過程，單獨啟動過單一etcd,做為測試驗證，集群內第一次啟動其他etcd服務時候，是通過發現服務引導的，所以需要刪除舊的成員信息
參考：One of the member was bootstrapped via discovery service. You must remove the previous data-dir to clean up the member information. Or the member will ignore the new configuration and start with the old configuration. That is why you see the mismatch.
