启动master和follower节点上etcd服务：
# systemctl start etcd
查看成员列表：
# etcdctl member list
30e9662cfab160c5: name=etcd2 peerURLs=http://10.10.0.49:2380 clientURLs=http://10.10.0.49:2379 isLeader=true
cedb09f4a212df57: name=etcd1 peerURLs=http://10.10.0.103:2380 clientURLs=http://10.10.0.103:2379 isLeader=false
查看集群状态：
# etcdctl cluster-health
member 30e9662cfab160c5 is healthy: got healthy result from http://10.10.0.49:2379
member cedb09f4a212df57 is healthy: got healthy result from http://10.10.0.103:2379
cluster is healthy
