测试环境

测试环境：
  Ubuntu 14.04 LTS x64
  ZooKeeper：zookeeper-3.4.6.tar.gz
  
  hostname		IP 		role
  spark-master： 192.168.108.20   master & worker
  spark-slave1： 192.168.108.21   worker
  spark-slave2： 192.168.108.22   worker
  
  !默认情况全部操作在root下进行

下载解压ZooKeeper

地址：ZooKeeper官方下载

#配置ssh免密码登录

请参考：Tachyon集群部署

修改目录权限

1	sudo chmod -R 775 zookeeper-3.4.6/

创建目录结构

进入ZooKeeper目录

1	mkdir data

1	mkdir logs

修改zoo.cfg配置文件

cp ./conf/zoo_sample.cfg ./conf/zoo.cfg
vim ./conf/zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/home/jabo/software/zookeeper-3.4.6/data #刚才创建的data目录
clientPort=2181
server.1=spark-master:2888:3888
server.2=spark-slave1:2888:3888
server.3=spark-slave2:2888:3888

ZooKeeper目录分发

将ZooKeeper目录分别复制到其他主机

ZooKeeper环境变量

/**
 * 分别配置每台主机的环境变量
 */
sudo vim /etc/profile
 
//添加如下信息
export ZOO_HOME=/home/jabo/software/zookeeper-3.4.6
export ZOO_LOG_DIR=$ZOO_HOME/logs
export PATH=$ZOO_HOME/bin:$PATH

//使配置生效
source /etc/profile

配置节点ID

/**
 * master切换至root下进行
 */
echo 1 >/home/jabo/software/zookeeper-3.4.6/data/myid
ssh spark-slave1 "echo 2 >/home/jabo/software/zookeeper-3.4.6/data/myid"
ssh spark-slave2 "echo 3 >/home/jabo/software/zookeeper-3.4.6/data/myid"

启动和关闭

/**
 * 启动(分别对每台主机进行启动)
 */
zkServer.sh start

//关闭
zkServer.sh stop
