一、安装条件前置

实验zookeeper安装在【Hadoop入门（二）集群安装】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

下载镜像

（2）上传到linux系统解压

1tar xvf apache-zookeeper-3.5.6-bin.tar.gz 
2#放在统一的软件目录下
3mv apache-zookeeper-3.5.6-bin ~/software/
4

（3） 新建数据目录

1cd ~/software/apache-zookeeper-3.5.6-bin
2#zk的数据目录
3mkdir -p zkData/data
4#zk的日子目录
5mkdir -p zkData/logs
6

（4）配置zoo.cfg

1cd ~/software/apache-zookeeper-3.5.6-bin/conf
2cp zoo_sample.cfg zoo.cfg
3vim zoo.cfg
4

编辑zoo.cfg

1# The number of milliseconds of each tick
2tickTime=2000
3# The number of ticks that the initial 
4# synchronization phase can take
5initLimit=10
6# The number of ticks that can pass between 
7# sending a request and getting an acknowledgement
8syncLimit=5
9# the directory where the snapshot is stored.
10# do not use /tmp for storage, /tmp here is just 
11# example sakes.
12
13# 注释掉默认dataDir
14# dataDir=/tmp/zookeeper
15#
16
17# the port at which the clients will connect
18clientPort=2181
19# the maximum number of client connections.
20# increase this if you need to handle more clients
21#maxClientCnxns=60
22#
23# Be sure to read the maintenance section of the 
24# administrator guide before turning on autopurge.
25#
26# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
27#
28# The number of snapshots to retain in dataDir
29#autopurge.snapRetainCount=3
30# Purge task interval in hours
31# Set to "0" to disable auto purge feature
32#autopurge.purgeInterval=1
33
34#新增的配置，server.i的i是数据目录zkData/data下的myid
35dataDir=/home/mk/software/apache-zookeeper-3.5.6-bin/zkData/data
36dataLogDir=/home/mk/software/apache-zookeeper-3.5.6-bin/zkData/logs
37server.1=hadoop01:2888:3888
38server.2=hadoop02:2888:3888
39server.3=hadoop03:2888:3888
40
41

（5）复制到hadoop02、hadoop03

1scp -r /home/mk/software/apache-zookeeper-3.5.6-bin mk@hadoop02:/home/mk/software/
2scp -r /home/mk/software/apache-zookeeper-3.5.6-bin mk@hadoop03:/home/mk/software/
3

（6）配置myid

hadoop01

1echo '1' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid
2

hadoop02

1echo '2' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid
2

hadoop03

1echo '3' > ~/software/apache-zookeeper-3.5.6-bin/zkData/data/myid
2

 

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

1~/software/apache-zookeeper-3.5.6-bin/bin/zkServer.sh  start
2
3

（2）检查启动状态

1~/software/apache-zookeeper-3.5.6-bin/bin/zkServer.sh  status
2
3

hadoop01 

 

hadoop02

hadoop03

** （3）创建节点**

haddoop01登录zk

1~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
2ls /
3create /test
4ls /
5delete /test
6
7

hadoop02登录zk

1~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
2ls /
3
4

hadoop03登录zk

1~/software/apache-zookeeper-3.5.6-bin/bin/zkCli.sh 
2ls /
3
4

（4）关闭

1~/software/apache-zookeeper-3.5.6-bin/binzkServer.sh  stop
2
