亦凉 2023-07-02 08:25 58阅读 0赞

### 一、安装条件前置 ###

实验zookeeper安装在【[Hadoop入门（二）集群安装][Hadoop]】机器上，已完成安装jdk,hadoop和ssh配置环境等。

zookeeper所依赖的虚拟机和操作系统配置

环境：ubuntu14 + apache-zookeeper-3.5.6-bin.tar + jdk1.8+ssh

虚拟机：（vmware10）

### 二、zookeeper安装环境设置 ###

**（1）下载**

[下载网站][Link 1]

**（2）上传到linux系统解压**

tar xvf apache-zookeeper-3.5.6-bin.tar.gz 
    #放在统一的软件目录下
    mv apache-zookeeper-3.5.6-bin ~/software/

**（3） 新建数据目录**

cd ~/software/apache-zookeeper-3.5.6-bin
    #zk的数据目录
    mkdir -p zkData/data
    #zk的日子目录
    mkdir -p zkData/logs

**（4）配置**zoo.cfg

cd ~/software/apache-zookeeper-3.5.6-bin/conf
    cp zoo_sample.cfg zoo.cfg
    vim zoo.cfg

编辑zoo.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.
    
    # 注释掉默认dataDir
    # 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
    
    #新增的配置，server.i的i是数据目录zkData/data下的myid
    dataDir=/home/mk/software/apache-zookeeper-3.5.6-bin/zkData/data
    dataLogDir=/home/mk/software/apache-zookeeper-3.5.6-bin/zkData/logs
    server.1=hadoop01:2888:3888
    server.2=hadoop02:2888:3888
    server.3=hadoop03:2888:3888

**（5）复制到hadoop02、hadoop03**

scp -r /home/mk/software/apache-zookeeper-3.5.6-bin mk@hadoop02:/home/mk/software/
    scp -r /home/mk/software/apache-zookeeper-3.5.6-bin mk@hadoop03:/home/mk/software/

**（6）配置myid**

hadoop01

echo '1' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid

hadoop02

echo '2' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid

hadoop03

echo '3' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid

### 三、启动Zookeeper ###

**（1）启动**

zookeeper没有集群启动需要每个机器各自启动

hadoop01、hadoop02、hadoop03都执行启动指令

~/software/apache-zookeeper-3.5.6-bin/bin/zkServer.sh  start

（2）检查启动状态

~/software/apache-zookeeper-3.5.6-bin/bin/zkServer.sh  status

**hadoop01**

![20200128130236153.png][]

![20200128142218313.png][]

**hadoop02**

![20200128130319655.png][]

![20200128142158643.png][]

**hadoop03**

![20200128130342576.png][]

![20200128142127804.png][]

** （3）创建节点**

haddoop01登录zk

~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
    ls /
    create /test
    ls /
    delete /test

hadoop02登录zk

~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
    ls /

![20200128143323676.png][]

![20200128143121161.png][]

hadoop03登录zk

~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
    ls /

![20200128143347981.png][]

![20200128143145303.png][]

**（4）关闭**

~/software/apache-zookeeper-3.5.6-bin/binzkServer.sh  stop
