Zookeeper環境安裝

Zookeeper源碼包下載

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

1. 集羣環境

Master 192.168.2.100
Slave1 192.168.2.101
Slave2 192.168.2.102

2. 下載軟件包

#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

#建立日誌文件夾及數據文件夾

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. 配置環境變量

#Master、Slave一、Slave2

vim ~/.bashrc

ZOOKEEPER_HOME=/usr/local/zookeeper-3.5.3

PATH=$PATH:$ZOOKEEPER_HOME/bin

#刷新環境變量

source ~/.bashrc

5. 拷貝安裝包

#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. 分別添加ID

ID要與配置文件中server.*中的數字對應

#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. 啓動Zookeeper服務

#Master、Slave一、Slave2

Slave一、Slave2也要執行此命令

zkServer.sh start

8. 查看運行狀態

zkServer.sh status

#Master

#Slave1

#Slave2

9. 進程狀態

jps

#Master         #Slave1               #Slave2

10. 關閉集羣

#master、Slave一、Slave2

zkServer.sh stop

三臺機器都要執行此命令
