zookeeper 学习记录-配置详解

# The number of milliseconds of each tick,
# Zookeeper 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。tickTime以毫秒为单位。session最小有效时间为tickTime*2
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
# 集群中的follower服务器(F)与leader服务器(L)之间初始连接时能容忍的最多心跳数（tickTime的数量），超过此数量没有回复会断开链接
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
# 集群中的follower服务器与leader服务器之间请求和应答之间能容忍的最多心跳数（tickTime的数量）
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# Zookeeper保存数据的目录，默认情况下，Zookeeper将写数据的日志文件也保存在这个目录里。不要使用/tmp目录
dataDir=/var/zookeeper
# the port at which the clients will connect
# 客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
# 最大客户端链接数量
maxClientCnxns=60

# 以下配置用于数据清理，开启之前务必阅读官方文档http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

# zookeeper集群配置项，server.1，server.2，server.3是zk集群节点；zoo1,zoo2,zoo3是主机名称；2888是主从通信端口；3888用来选举leader
server.1=zoo1:2888:3888
server.2=zoo2:2888:3888
server.3=zoo3:2888:3888
