tickTime:心跳时间,为了确保连接存在的,以毫秒为单位,最小超时时间为两个心跳时间
initLimit:多少个心跳时间内,允许其他server连接并初始化数据,如果ZooKeeper管理的数据较大,则应相应增大这个值
clientPort:服务的监听端口
dataDir:用于存放内存数据库快照的文件夹,同时用于集群的myid文件也存在这个文件夹里(注意:一个配置文件只能包含一个dataDir字样,即使它被注释掉了。)
dataLogDir:用于单独设置transaction log的目录,transaction log分离可以避免和普通log还有快照的竞争
syncLimit:多少个tickTime内,允许follower同步,如果follower落后太多,则会被丢弃。
server.A=B:C:D:
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第一个端口用来集群成员的信息交换,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是在leader挂掉时专门用来进行选举leader所用
