1. 简介
ZooKeeper是一个分布式的，开放源码的分布式应用程序协调服务，是Google的Chubby一个开源的实现，是Hadoop和Hbase的重要组件。它是一个为分布式应用提供一致性服务的软件，提供的功能包括：配置维护、域名服务、分布式同步、组服务等。
ZooKeeper的目标就是封装好复杂易出错的关键服务，将简单易用的接口和性能高效、功能稳定的系统提供给用户。
2. 下载安装包
- 访问地址
https://zookeeper.apache.org/releases.html - 选择需要下载的版本，点击下载
- 下载后解压
3. 修改配置
- 在apache-zookeeper-3.7.0-bin根目录下创建两个文件夹：
data和log
- 打开apache-zookeeper-3.7.0-binconf目录，将
zoo_sample.cfg复制一份，命名为zoo.cfg - 打开
zoo.cfg，修改dataDir路径，新增日志dataLogDir路径
- tickTime=2000
客户端和服务器之间或者集群模式下服务器时间发送心跳的间隔时间，单位毫秒。 - initLimit=10
初始化时最大可以接受的心跳间隔数，即连续10个心跳间隔时间内（10 * 2000ms = 20s），服务器还未收到客户端信息，则认为客户端连接失败。 - syncLimit=5
发送请求和应答时间长度，5 * 2000ms =10s。 - dataDir=../data
保存数据目录。 - dataLogDir=../log
保存日志目录。 - clientPort=2181
连接端口号。 - maxClientCnxns=12
客户端最大连接数。
- tickTime=2000
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=../data
dataLogDir=../log
# the port at which the clients will connect
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.
#
# 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
4. 启动
- 打开apache-zookeeper-3.7.0-binin目录，双击
