Zookeeper环境安装

Zookeeper源码包下载

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

1. 集群环境

Master 192.168.2.100
Slave1 192.168.2.101
Slave2 192.168.2.102

2. 下载软件包

#Master

wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.3/zookeeper-3.5.3.tar.gz

tar zxvf zookeeper-3.5.3.tar.gz

3. 修改zookeeper配置

#Master

cd zookeeper-3.5.3

#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/zookeeper-3.5.3-beta/data

dataLogDir=/usr/local/zookeeper-3.5.3/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/zookeeper-3.5.3

PATH=$PATH:$ZOOKEEPER_HOME/bin

#刷新环境变量

source ~/.bashrc

5. 拷贝安装包

#Master

scp -r /usr/local/zookeeper-3.5.3 root@slave1:/usr/local/zookeeper-3.5.3

scp -r /usr/local/zookeeper-3.5.3 root@slave2:/usr/local/zookeeper-3.5.3

6. 分别添加ID

ID要与配置文件中server.*中的数字对应

#Master

echo "1" >  /usr/local/zookeeper-3.5.3/data/myid    

#Slave1

echo "2" >  /usr/local/zookeeper-3.5.3/data/myid  

#Slave2

echo "3" >  /usr/local/zookeeper-3.5.3/data/myid  

7. 启动Zookeeper服务

#Master、Slave1、Slave2

Slave1、Slave2也要执行此命令

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

三台机器都要执行此命令
