原因是：我的集群中没有node0，只有node1，node2和node3 ，
这里的server.0 ，server.1和server.2 是对应的myid 中的 0,1,2
server.0=node0:2888:3888
server.1=node1:2888:3888
server.2=node2:2888:3888

修改：（这里配置时，一定要要和自己集群中每台机器的IP对应上）
server.0=node1:2888:3888
server.1=node2:2888:3888
server.2=node3:2888:3888

server.A=B：C：D：其中 A 是一个数字，表示这个是第几号服务器；B 是这个服务器的 ip 地址；
C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口；
D 表示的是万一集群中的 Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的 Leader，
而这个端口就是用来执行选举时服务器相互通信的端口。
