一、安裝條件前置

實驗zookeeper安裝在【Hadoop入門（二）集群安裝】機器上，已完成安裝jdk,hadoop和ssh配置環(huán)境等。

zookeeper所依賴的虛擬機和操作系統(tǒng)配置

環(huán)境：ubuntu14 + apache-zookeeper-3.5.6-bin.tar + jdk1.8+ssh

虛擬機：（vmware10）

?

二、zookeeper安裝環(huán)境設(shè)置

（1）下載

下載網(wǎng)站

下載鏡像

（2）上傳到linux系統(tǒng)解壓

tar xvf apache-zookeeper-3.5.6-bin.tar.gz #放在統(tǒng)一的軟件目錄下 mv apache-zookeeper-3.5.6-bin ~/software/

（3） 新建數(shù)據(jù)目錄

cd ~/software/apache-zookeeper-3.5.6-bin #zk的數(shù)據(jù)目錄 mkdir -p zkData/data #zk的日子目錄 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

編輯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.# 注釋掉默認(rèn)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是數(shù)據(jù)目錄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）復(fù)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、啟動Zookeeper

（1）啟動

zookeeper沒有集群啟動需要每個機器各自啟動

hadoop01、hadoop02、hadoop03都執(zhí)行啟動指令

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

（2）檢查啟動狀態(tài)

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

hadoop01?

?

hadoop02

hadoop03

?（3）創(chuàng)建節(jié)點

haddoop01登錄zk

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

hadoop02登錄zk

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

hadoop03登錄zk

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

（4）關(guān)閉

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

?
