    —data-dir 指定节点的数据存储目录，这些数据包括节点ID，集群ID，集群初始化配置，Snapshot文件，若未指定—wal-dir，还会存储WAL文件；
    —wal-dir 指定节点的was文件的存储目录，若指定了该参数，wal文件会和其他数据文件分开存储。
    —name 节点名称
    —initial-advertise-peer-urls 告知集群其他节点url.
    —listen-peer-urls 监听URL，用于与其他节点通讯
    —advertise-client-urls 告知客户端url, 也就是服务的url
    —initial-cluster-token 集群的ID
    —initial-cluster 集群中所有节点
