zookeeper 配置文件详解
# The number of milliseconds of each tick 心跳间隔 毫秒每次
# 通信心跳数,Zookeeper服务器与客户端心跳时间,单位毫秒
# Zookeeper使用的基本时间,服务器之间或客户端与服务器之间维持心跳的时间间隔,也就是每个tickTime时间就会发送一个心跳,时间单位为毫秒。
# 它用于心跳机制,并且设置最小的session超时时间为两倍心跳时间。(session的最小超时时间是2*tickTime)
tickTime=2000
# The number of ticks that the initial ; synchronization phase can take
# LF初始通信时限
# 集群中的Follower跟随者服务器与Leader领导者服务器之间初始连接时能容忍的最多心跳数(tickTime的数量),用它来限定集群中的Zookeeper服务器连接到Leader的时限。
# 10个2000ms
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
# LF同步通信时限
# 集群中Leader与Follower之间的最大响应时间单位,假如响应超过syncLimit * tickTime,Leader认为Follwer死掉,从服务器列表中删除Follwer。
# 5个2000ms
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# 镜像数据位置 数据文件目录+数据持久化路径

# the port at which the clients will connect
# 客户端连接的端口
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.

#autopurge.purgeInterval=1
# server.A=B:C:D
# A 是一个数字,表示这个是第几号服务器,就是myid文件中的数字;
# 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。
