server0ip:192.168.88.155(hadoop01)

server1ip:192.168.88.164(hadoop02)

server2ip:192.168.88.165(hadoop03)

解压到app目录下

[root@hadoop02 Desktop]# tar -zxvf zookeeper-3.4.5.tar.gz -C app/

[root@hadoop02 Desktop]# cd app

[root@hadoop02 app]# cd zookeeper-3.4.5

[root@hadoop02 zookeeper-3.4.5]# cd conf

[root@hadoop02 conf]# mv zoo_sample.cfg zoo.cfg

vi zoo.cfg

dataDir=/root/Desktop/app/zookeeper-3.4.5/data

添加

server.1=hadoop01:2888:3888
server.2=hadoop02:2888:3888
server.3=hadoop03:2888:3888

[root@hadoop02 conf]# cd ..
[root@hadoop02 zookeeper-3.4.5]# mkdir data

[root@hadoop02 zookeeper-3.4.5]# cd data

[root@hadoop02 data]# echo 1 >myid
[root@hadoop02 data]# cat myid
1

[root@hadoop02 data]# cd ..
[root@hadoop02 zookeeper-3.4.5]# cd ..
[root@hadoop02 app]# ls
zookeeper-3.4.5

[root@hadoop02 app]# scp -r zookeeper-3.4.5/ hadoop02:/root/Desktop/app

进入hadoop02的主机

[root@localhost ~]# cd /root/Desktop/app

[root@localhost app]# cd zookeeper-3.4.5
[root@localhost zookeeper-3.4.5]# ls
bin          dist-maven       NOTICE.txt            zookeeper-3.4.5.jar.asc
build.xml    docs             README_packaging.txt  zookeeper-3.4.5.jar.md5
CHANGES.txt  ivysettings.xml  README.txt            zookeeper-3.4.5.jar.sha1
conf         ivy.xml          recipes
contrib      lib              src
data         LICENSE.txt      zookeeper-3.4.5.jar

[root@localhost zookeeper-3.4.5]# cd data
[root@localhost data]# ls
myid
[root@localhost data]# echo 2 >myid
[root@localhost data]# cat myid
2

进入hadoop03的server

[root@localhost app]# cd zookeeper-3.4.5
[root@localhost zookeeper-3.4.5]# ls
bin          docs                  README.txt
build.xml    ivysettings.xml       recipes
CHANGES.txt  ivy.xml               src
conf         lib                   zookeeper-3.4.5.jar
contrib      LICENSE.txt           zookeeper-3.4.5.jar.asc
data         NOTICE.txt            zookeeper-3.4.5.jar.md5
dist-maven   README_packaging.txt  zookeeper-3.4.5.jar.sha1

[root@localhost data]# ls
myid
[root@localhost data]# echo 3 >myid
[root@localhost data]# cat myid
3

启动集群

[root@hadoop02 conf]# cd ..

[root@hadoop02 zookeeper-3.4.5]# cd bin

[root@hadoop02 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@hadoop02 bin]# jps
5386 NodeManager
20801 Jps
4912 DataNode
5288 ResourceManager
17430 QuorumPeerMain
5126 SecondaryNameNode

同理启动hadoop02

[root@localhost zookeeper-3.4.5]# cd bin
[root@localhost bin]# ls
README.txt    zkCli.cmd  zkEnv.cmd  zkServer.cmd
zkCleanup.sh  zkCli.sh   zkEnv.sh   zkServer.sh
[root@localhost bin]# ./zkServer.sh start
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]# jps
9635 QuorumPeerMain
5538 SecondaryNameNode
5722 ResourceManager
9649 Jps
5195 NameNode
5820 NodeManager
5322 DataNode

启动hadoop03

root@localhost zookeeper-3.4.5]# cd bin
[root@localhost bin]# ls
README.txt    zkCli.cmd  zkEnv.cmd  zkServer.cmd
zkCleanup.sh  zkCli.sh   zkEnv.sh   zkServer.sh
[root@localhost bin]# ./zkServer.sh start
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]# jps
9275 Jps
5520 SecondaryNameNode
5691 ResourceManager
5789 NodeManager
9251 QuorumPeerMain
5310 DataNode

hadoop01

[root@hadoop02 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: follower
hadoop02

[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: leader

hadoop03

root@localhost bin]#  ./zkServer.sh status
JMX enabled by default
Using config: /root/Desktop/app/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: follower
若出现Error contacting service. It is probably not running. error

一般是zookeeper-3.4.5 集群启动不成功， 在确保每台zookeeper-3.4.5启动后若还是出现问题

[root@hadoop01 ~]# find / -name zookeeper.out
/root/Desktop/app/zookeeper-3.4.5/bin/zookeeper.out

找出日志的位置查看

 tail -50 /root/Desktop/app/zookeeper-3.4.5/bin/zookeeper.out

   连接客户端

[root@hadoop02 bin]# sh zkCli.sh

[zk: localhost:2181(CONNECTED) 0] help帮助

[zk: localhost:2181(CONNECTED) 1] ls /
[zookeeper]
[zk: localhost:2181(CONNECTED) 2] create /hadoop 78
Created /hadoop

[zk: localhost:2181(CONNECTED) 4] get /hadoop
78

[zk: localhost:2181(CONNECTED) 7] set /hadoop xxxx

[zk: localhost:2181(CONNECTED) 5] create /hadoop/test mon:hadooop;tue:hdfs;
Created /hadoop/test
[zk: localhost:2181(CONNECTED) 6] get /hadoop/test
mon:hadooop;tue:hdfs;

连接hadoop03

[zk: localhost:2181(CONNECTED) 0] get /hadoop
78
kill -9  jps的线程
