zookeeper系列：单机模式部署

一、官方网站下载安装包

选择需要的版本，下载相关压缩包（例：apache-zookeeper-3.7.0-bin.tar.gz ）

二、正式安装

[root@i-slebi7x6 opt]# cd zookeeper/
[root@i-slebi7x6 zookeeper]# ls
apache-zookeeper-3.7.0.tar.gz
[root@i-slebi7x6 zookeeper]# tar -zxf  apache-zookeeper-3.7.0-bin.tar.gz
[root@i-slebi7x6 zookeeper]# ls
apache-zookeeper-3.7.0-bin  
[root@i-slebi7x6 zookeeper]# cd apache-zookeeper-3.7.0-bin
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# ls
bin  conf  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# mkdir data
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# ls
bin  conf  data  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md

2、复制conf目录下的zoo_sample.cfg为zoo.cfg。

[root@i-slebi7x6 conf]# cp zoo_sample.cfg zoo.cfg
[root@i-slebi7x6 conf]# ls
configuration.xsl  log4j.properties  zoo.cfg  zoo_sample.cfg

3、修改相关属性，配置dataDir地址。

zoo_sample.cfg

# 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=/tmp/zookeeper
# 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、执行bin/zkServer.sh，启动zookeeper。

[root@i-slebi7x6 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/apache-zookeeper-3.7.0-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

停止zookeeper

./zkServer.sh stop

5、启动CLI

[root@i-slebi7x6 bin]# ./zkCli.sh
