Apache Hadoop生态-目录汇总-持续更新

系统环境：centos7

Java环境：Java8

免密与基础配置参考：Apache Hadoop生态部署-3台设置的免密登录，xsync分发脚本，jpsall脚本

单机安装参考上篇：Apache Hadoop生态部署-zookeeper单机安装

服务分布如下：

	node01(6G内存)	node02(6G内存)	node03(6G内存)
Zookeeper	√	√	√

 一：安装前准备

1：zookeeper安装包选择--官网下载

Index of /dist/zookeeper

 2：zookeeper3.5.7安装包--百度网盘

提取码：yyds

二：安装与常用配置

2.1：下载解压zk安装包

[root@node01 ~]# cd /tmp
[root@node01 tmp]# wget https://archive.apache.org/dist/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7-bin.tar.gz
或者从百度网盘下载，上传到/tmp下


解压到/usr/local/
[root@node01 tmp]# sudo tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /usr/local/
[root@node01 tmp]# sudo mv /usr/local/apache-zookeeper-3.5.7-bin /usr/local/zookeeper-3.5.7

2.2：配置环境变量

sudo vim /etc/profile.d/zookeeper.sh
插入内容
export ZOOKEEPER_HOME=/usr/local/zookeeper-3.5.7
export PATH=$PATH:$ZOOKEEPER_HOME/bin

执行source /etc/profile使环境变量生效

2.3：配置修改

（1）备份配置文件zoo_sample.cfg
[root@node01 tmp]# cd /usr/local/zookeeper-3.5.7/conf
[root@node01 conf]# sudo cp zoo_sample.cfg zoo.cfg

（2）修改zoo.cfg配置
创建数据存放目录
[root@node01 conf]# mkdir -p /usr/local/zookeeper-3.5.7/data


[root@node01 conf]# sudo vim /usr/local/zookeeper-3.5.7/conf/zoo.cfg
# 修改 dataDir 路径
dataDir=/usr/local/zookeeper-3.5.7/data
# 在最后添加上以下内容，其中2888是通讯端口，3888是选举端口
server.1=node01:2888:3888
server.2=node02:2888:3888
server.3=node03:2888:3888


（3）配置myid
[root@node01 conf]# vim $ZOOKEEPER_HOME/data/myid
1

# 注意LISTEN  2181端口，2888端口，3888端口，8080端口(注意冲突)

2.4：分发zookeeper到node02, node03节点

scp -r /usr/local/zookeeper-3.5.7 root@node02:/usr/local/
scp -r /usr/local/zookeeper-3.5.7 root@node03:/usr/local/

或者使用自编写的同步脚本
~/xsync /usr/local/zookeeper-3.5.7

2.5：修改node02, node03节点的myid

[root@node02 conf]# vim $ZOOKEEPER_HOME/data/myid
2

[root@node03 conf]# vim $ZOOKEEPER_HOME/data/myid
3

#写上配置文件服务器对应server的值，必须与配置文件编号一致
node01中myid填1
node02中myid填2
node03中myid填3

三：Zookeeper基础操作

3.1：服务管理

编写脚本操作Zookeeper
vim $ZOOKEEPER_HOME/bin/myzookeeper.sh

#!/bin/bash
if [ $# -lt 1 ]
then
	echo "No Args Input..."
	exit ;
fi

case $1 in
"start")
   for i in node01 node02 node03
	do
		echo ---------- zookeeper $i 启动 ------------
		ssh $i "/usr/local/zookeeper-3.5.7/bin/zkServer.sh start"
	done
;;
"stop")
	for i in node01 node02 node03
	do
		echo ---------- zookeeper $i 关闭 ------------
		ssh $i "/usr/local/zookeeper-3.5.7/bin/zkServer.sh stop"
	done
;;
"status")
	for i in node01 node02 node03
	do
		echo ---------- zookeeper $i 状态 ------------
		ssh $i "/usr/local/zookeeper-3.5.7/bin/zkServer.sh status"
	done
;;
*)
	echo "Input Args Error..."
;;
esac


添加可执行权限
chmod +x $ZOOKEEPER_HOME/bin/myzookeeper.sh

# 启动 Zookeeper
$ myzookeeper.sh start

# 查看状态
$ myzookeeper.sh status

# 停止 Zookeeper
$ myzookeeper.sh stop
