1.下载官网：http://zookeeper.apache.org/releases.html镜像：https://www.apache.org/dyn/closer.cgi/zookeeper2.安装ZooKeeper在Java环境下运行，所以你需要先安装JDK。网上教程很多，我就不赘述了。也可以参考我的另一篇文章：在CentOS上安装JDK解压shell>tar-xvfzookeeper-3.5.3-beta.tar.gz-C/usr/local/修改配置shell>cd/usr/local/zookeeper-3.5.3-beta/confshell>cpzoo_sample.cfgzoo.cfgshell>vimzoo.cfgdataDir=/usr/local/zookeeper-3.5.3-beta/datadataLogDir=/usr/local/zookeeper-3.5.3-beta/logs3.启动和停止1.启动shell>bin/zkServer.shstartZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgStartingzookeeper...STARTED2,查看statusshell>bin/zkServer.shstatusZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg发现客户端端口：2181。客户端地址：localhost。模式：standalone3、Stopshell>bin/zkServer.shstopZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgStoppingzookeeper...STOPPED4、重新启动shell>bin/zkServer.shrestartZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgStoppingzookeeper...STOPPEDZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgStartingzookeeper...STARTED四、测试1、jps，查看QuorumPeerMain是否存在于shell>jps19748Jps19159QuorumPeerMain2、zkServer.shstatusshell>bin/zkServer.shstatusZooKeeperJMXenabledbydefaultUsingconfig:/usr/local/zookeeper-3.5.3-beta/bin/../conf/zoo.cfgClientportfound:2181.Clientaddress:localhost.Mode:standalone3、zkClientshell>bin/zkCli.sh-serverlocalhost:2181Connectingtolocalhost:21812020-03-2623:41:43,303[myid:]-INFO[main:Environment@109]-客户端环境：zookeeper.version=3.5.3-beta-8ce24f9e675cbefffb8f21a47e06b42864475a60，建立于04/03/201716:19GMT2020-03-2623:41:43,306[myid:]-INFO[main:Environment@109]-客户端环境：host.name=VM_2_24_centos2020-03-2623:41:43,306[myid:]-INFO[main:Environment@109]-客户端环境：java.version=1.8.0_2412020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：java.vendor=OracleCorporation2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：java.home=/usr/local/java/jdk1.8.0_241/jre2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：java.class.path=/usr/local/zookeeper-3.5.3-beta/bin/../build/classes:/usr/local/zookeeper-3.5.3-beta/bin/../build/lib/*.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/slf4j-log4j12-1.7.5.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/slf4j-api-1.7.5.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/netty-3.10.5.Final.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/log4j-1.2.17.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jline-2.11.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jetty-util-9.2.18.v20160721.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jetty-servlet-9.2.18.v20160721.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jetty-server-9.2.18.v20160721。jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jetty-security-9.2.18.v20160721.jar:/usr/local/zookeeper-3.5.3-beta/bin/。./lib/jetty-io-9.2.18.v20160721.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jetty-http-9.2.18.v20160721.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/javax.servlet-api-3.1.0.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jackson-mapper-asl-1.9.11.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/jackson-core-asl-1.9.11.jar:/usr/local/zookeeper-3.5.3-beta/bin/../lib/commons-cli-1.2.jar:/usr/local/zookeeper-3.5.3-beta/bin/../zookeeper-3.5.3-beta.jar:/usr/local/zookeeper-3.5.3-beta/bin/../src/java/lib/*.jar:/usr/local/zookeeper-3.5.3-beta/bin/../conf:.:/usr/local/java/jdk1.8.0_241/lib/dt.jar:/usr/local/java/jdk1.8.0_241/lib/tools.jar2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-Clientenvironment:java.library.path=/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：java。io.tmpdir=/tmp2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：java.compiler=2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-Clientenvironment:os.name=Linux2020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-Clientenvironment:os.arch=amd642020-03-2623:41:43,308[myid:]-信息[main:Environment@109]-客户端环境：os.version=3.10.0-1062.9.1.el7.x86_642020-03-2623:41:43,308[myid:]-INFO[main:Environment@109]-客户端环境：user.name=root2020-03-2623:41:43,309[myid:]-INFO[main:Environment@109]-客户端环境：user.home=/root2020-03-2623:41:43,309[myid:]-信息[main:Environment@109]-客户端环境：user.dir=/usr/local/zookeeper-3.5.3-beta2020-03-2623:41:43,309[myid:]-INFO[main:Environment@109]-客户端环境：os.memory.free=52MB2020-03-2623:41:43,310[myid:]-INFO[main:Environment@109]-客户端环境：os.memory.max=228MB2020-03-2623:41:43,310[myid:]-INFO[main:Environment@109]-客户端环境：os.memory.total=57MB2020-03-2623:41:43,313[myid:]-INFO[main:ZooKeeper@865]-启动客户端连接，connectString=localhost:2181sessionTimeout=30000watcher=org.apache.zookeeper.ZooKeeperMain$MyWatcher@5e8c92f42020-03-2623:41:43,323[myid:]-INFO[main:ClientCnxnSocket@236]-jute.maxbuffer值为4194304BytesWelcometoZooKeeper！2020-03-2623:41:43,335[myid:localh
