安装zookeeper集群

1.上传安装包，并解压

tar -zvxf zookeeper-3.4.6.tar.gz

2.修改配置文件

cp zoo_sample.cfg zoo.cfg

修改conf/zoo.cfg

#修改路径
dataDir=/root/zkdata
#追加
server.1=hdp-01:2888:3888
server.2=hdp-02:2888:3888
server.3=hdp-03:2888:388

3.配置文件修改完，将安装包发送到hdp-02和hdp-03

scp -r zookeeper-3.4.6/ hdp-03:$PWD
scp -r zookeeper-3.4.6/ hdp-02:$PWD

4.创建/root/zkdata目录，目录下添加myid文件

hdp-01内容为1 echo 1 > /root/zkdata/myid

hdp-02内容为2 echo 2> /root/zkdata/myid

hdp-03内容为3 echo 3 > /root/zkdata/myid

5.启动集群

批量启动脚本

#!/bin/bash
for host in hdp-01 hdp-02 hdp-03
do
echo "${host} ${1}ing...."
ssh $host "source /etc/profile;/root/apps/zookeeper-3.4.6/bin/zkServer.sh $1"
done
sleep 2
for host in hdp-01 hdp-02 hdp-03
do
ssh $host "source /etc/profile;/root/apps/zookeeper-3.4.6/bin/zkServer.sh status"
done

 启动zookeeper命令行客户端

zkCli.sh -server hdp-01:2181
