一、官方网站下载安装包
Index of /zookeeper
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
1、解压目录，并且新建data目录
[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
zoo.cfg

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 Connecting to localhost:2181 2022-01-19 16:16:37,390 [myid:] - INFO [main:Environment@98] - Client environment:zookeeper.version=3.7.0-e3704b390a6697bfdf4b0bef79e3da7a4f6bac4b, built on 2021-03-17 09:46 UTC 2022-01-19 16:16:37,393 [myid:] -
