1、下载解压Zookeeper3.4.6
hadoop@master:~/opt$ tar -zxvf zookeeper-3.4.6.tar.gz
2、Zookeeper环境变量的配置
hadoop@master:~$ vim ~/.bashrc
# set zookeeper environment
export ZOOKEEPER_HOME=/home/hadoop/opt/zookeeper-3.4.6
export PATH=$PATH:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf
3、更改配置文件
将conf/zoo_sample.cfg改成conf/zoo.cfg并修改成如下：
dataDir=/home/hadoop/opt/zookeeper-3.4.6/var/data
# the port at which the clients will connect
clientPort=2181
server.1=master:2888:3888
server.2=slave1:2888:3888
4、在DataDir路径下创建myid文件
hadoop@master:~/opt/zookeeper-3.4.6$ mkdir var
hadoop@master:~/opt/zookeeper-3.4.6$ cd var
hadoop@master:~/opt/zookeeper-3.4.6/var$ mkdir data
hadoop@master:~/opt/zookeeper-3.4.6/var$ mkdir datalog
hadoop@master:~/opt/zookeeper-3.4.6/var$ cd data
hadoop@master:~/opt/zookeeper-3.4.6/var/data$ vim myid
5、分发到集群的其它机器
hadoop@master:~$ scp -r /home/hadoop/opt/zookeeper-3.4.6 hadoop@slave1:/home/hadoop/opt
6、启动与关闭zookeeper
hadoop@master:~$ cd ~/opt/zookeeper-3.4.6/bin
hadoop@master:~/opt/zookeeper-3.4.6/bin$ ./zkServer.sh start
JMX enabled by default
Using config: /home/hadoop/opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper … STARTED
表示启动成功！
要想关闭zookeeper，运行下面的命令：
hadoop@master:~/opt/zookeeper-3.4.6/bin$ ./zkServer.sh stop
JMX enabled by default
Using config: /home/hadoop/opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED
