基於Hadoop2.6.x叢集安裝Zookeeper
a.下載軟體包zookeeper-3.4.5.tar.gz
#Master
wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz
tar zxvf zookeeper-3.4.5.tar.gz
b.修改zookeeper配置
#Master
cd zookeeper-3.4.5
#建立日誌資料夾及資料資料夾
mkdir data
mkdir log
#修改配置
cd conf
mv zoo_sample.cfg zoo.cfg
vim zoo.cfg
dataDir=/usr/local/src/zookeeper-3.4.5/data
dataLogDir=/usr/local/src/zookeeper-3.4.5/log
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888
c.配置環境變數
#Master、Slave1、Slave2
vim ~/.bashrc
export ZOOKEEPER_HOME=/usr/local/src/zookeeper-3.4.5
export PATH=$PATH:$ZOOKEEPER_HOME/bin
#重新整理環境變數
source ~/.bashrc
d. 拷貝安裝包
#Master
scp -r /usr/local/src/zookeeper-3.4.5 [email protected]:/usr/local/src/zookeeper-3.4.5
scp -r /usr/local/src/zookeeper-3.4.5 [email protected]:/usr/local/src/zookeeper-3.4.5
e.分別新增ID
#Master
echo "1" > /usr/local/src/zookeeper-3.4.5/data/myid
#Slave1
echo "2" > /usr/local/src/zookeeper-3.4.5/data/myid
#Slave2
echo "3" > /usr/local/src/zookeeper-3.4.5/data/myid
f. 啟動Zookeeper服務
#Master、Slave1、Slave2
zkServer.sh start
g. 檢視執行狀態
zkServer.sh status
#Master
#Slave1
#Slave2
h.檢視程序狀態
jps
#Master
#Slave1
#Slave2
i. 關閉叢集
#master、Slave1、Slave2
zkServer.sh stop
