数仓4.0笔记——用户行为数据采集二

 1 Zookeeper安装

[[email protected] software]$ tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module/

 

 修改名字，只留下对应版本号

 [[email protected] module]$ cd zookeeper-3.5.7/

[[email protected] zookeeper-3.5.7]$ mkdir zkData

[[email protected] zookeeper-3.5.7]$ cd zkData/

[[email protected] zkData]$ vim myid

 

分发

[[email protected] zkData]$ xsync myid

并分别在hadoop103、hadoop104上修改myid文件中内容为3、4

 

配置zoo.cfg文件

 [[email protected] conf]$ mv zoo_sample.cfg zoo.cfg

 原本的样子

 

修改数据存储路径配置

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

增加如下配置

#######################cluster##########################

server.2=hadoop102:2888:3888

server.3=hadoop103:2888:3888

server.4=hadoop104:2888:3888

 

 

 在103上检查一下

 配置好了，启动一下

[[email protected] zookeeper-3.5.7]$ bin/zkServer.sh start

[[email protected] zookeeper-3.5.7]$ bin/zkServer.sh start

[[email protected] zookeeper-3.5.7]$ bin/zkServer.sh start

 

查看总体进程

 查看状态

[[email protected] zookeeper-3.5.7]$ bin/zkServer.sh status

 

 

 2 ZK集群启动停止脚本

在hadoop102的/home/atguigu/bin目录下创建脚本

 [[email protected] bin]$ vim zk.sh

       在脚本中编写如下内容

#!/bin/bash

case $1 in
"start"){
	for i in hadoop102 hadoop103 hadoop104
	do
        echo ---------- zookeeper $i 启动 ------------
		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 状态 ------------    
		ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
	done
};;
esac
