Zookeeper環境搭建

1.拷貝 apache-zookeeper-3.5.7-bin.tar.gz到/opt/software目錄下

2.解壓到指定目錄

tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module/

3.修改名稱

cd /opt/module

mv apache-zookeeper-3.5.7-bin/ zookeeper-3.5.7

4.配置修改

mv zoo_sample.cfg zoo.cfg

dataDir=/opt/module/zookeeper-3.5.7/zkData

mkdir zkData

vim myid

5.拷貝配置好的 zookeeper 到其他機器上

xsync zookeeper-3.5.7

vim zoo.cfg

#######################cluster##########################
server.2=hadoop102:2888:3888
server.3=hadoop103:2888:3888
server.4=hadoop104:2888:3888

xsync zoo.cfg

7.在 hadoop102 的/home/guo/bin 目錄下創建Zookeeper集群腳本(guo為用戶名)

vim zk.sh

#!/bin/bash
case $1 in
"start"){
for i in hadoop102 hadoop103 hadoop104
do
 echo ---------- zookeeper $i 啟動 ------------
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh start"
done
};;
"stop"){
for i in hadoop102 hadoop103 hadoop104
do
 echo ---------- zookeeper $i 停止 ------------ 
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh stop"
done
};;
"status"){
for i in hadoop102 hadoop103 hadoop104
do
 echo ---------- zookeeper $i 狀態 ------------ 
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
done
};;
esac

chmod 777 zk.sh

zk.sh start

zk.sh stop
