检查配置文件：
#[Member] ETCD_LISTEN_PEER_URLS="http://8.8.8.8:2380" ETCD_LISTEN_CLIENT_URLS="http://localhost:2379,http://8.8.8.8:2379" ETCD_NAME="default" #[Clustering] ETCD_INITIAL_ADVERTISE_PEER_URLS="http://8.8.8.8:2380" ETCD_ADVERTISE_CLIENT_URLS="http://8.8.8.8:2379" ETCD_INITIAL_CLUSTER="etcd0=http://8.8.8.8:2380" ETCD_INITIAL_CLUSTER_TOKEN="cluster1" ETCD_INITIAL_CLUSTER_STATE="new"
可以看到：
ETCD_NAME="default" ETCD_INITIAL_CLUSTER="etcd0=http://8.8.8.8:2380"
这里参数配置不一致。改成一致就可以了。
