大数据之zookeeper环境搭建

zookeeper源码包下载

http://mirror.bit.edu.cn/apache/zookeeper/

1. 集群环境

Master 172.16.11.97

Slave1 172.16.11.98

Slave2 172.16.11.99

2. 下载软件包

#Master

wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

tar zxvf zookeeper-3.4.10.tar.gz

3. 修改zookeeper配置

#Master

cd zookeeper-3.4.10

#创建日志文件夹及数据文件夹

mkdir data

mkdir log

#修改配置

cd conf

mv zoo_sample.cfg zoo.cfg

vim zoo.cfg

dataDir=/usr/local/src/zookeeper-3.4.10/data

dataLogDir=/usr/local/src/zookeeper-3.4.10/log

server.1=master:2888:3888

server.2=slave1:2888:3888

server.3=slave2:2888:3888

4. 配置环境变量

#Master、Slave1、Slave2

vim ~/.bashrc

ZOOKEEPER_HOME=/usr/local/src/zookeeper-3.4.10

PATH=$PATH:$ZOOKEEPER_HOME/bin

#刷新环境变量

source ~/.bashrc

5. 拷贝安装包

#Master

scp -r /usr/local/src/zookeeper-3.4.10 root@slave1:/usr/local/src/zookeeper-3.4.10

scp -r /usr/local/src/zookeeper-3.4.10 root@slave2:/usr/local/src/zookeeper-3.4.10

6. Node上分别添加ID

#Master

echo "1" > /usr/local/src/zookeeper-3.4.10/data/myid

#Slave1

echo "2" > /usr/local/src/zookeeper-3.4.10/data/myid

#Slave2

echo "3" > /usr/local/src/zookeeper-3.4.10/data/myid

7. 启动Zookeeper服务

#Master、Slave1、Slave2

zkServer.sh start

8. 查看运行状态

zkServer.sh status

#Master

#Slave1

#Slave2

9. 进程状态

jps

#Master

#Slave1

#Slave2

10. 关闭集群

#master、Slave1、Slave2

zkServer.sh stop
