# name 节点名称
# data-dir 指定节点的数据存储目录
# listen-peer-urls 监听URL，用于与其他节点通讯
# listen-client-urls 对外提供服务的地址：比如 http://ip:2379,http://127.0.0.1:2379 ，客户端会连接到这里和 etcd 交互
# initial-advertise-peer-urls 该节点member(同伴)监听地址，这个值会告诉集群中其他节点
# initial-cluster 集群中所有节点的信息，格式为 node1=http://ip1:2380,node2=http://ip2:2380,… 。注意：这里的 node1 是节点的 --name 指定的名字；后面的 ip1:2380 是 --initial-advertise-peer-urls 指定的值
# initial-cluster-state 新建集群的时候，这个值为 new ；假如已经存在的集群，这个值为 existing
# initial-cluster-token 创建集群的 token，这个值每个集群保持唯一。这样的话，如果你要重新创建集群，即使配置和之前一样，也会再次生成新的集群和节点 uuid；否则会导致多个集群之间的冲突，造成未知的错误
# advertise-client-urls 对外公告的该节点客户端监听地址，这个值会告诉集群中其他节点
