zookeeper 安裝、設定 (Cluster)

相關軟體安裝、設定:
hadoop 安裝配置: http://sc8log.blogspot.tw/2017/04/hadoop-cluster.html
hbase 安裝、設定: http://sc8log.blogspot.tw/2017/04/hbase-cluster.html

下載 zookeeper:
wget http://apache.stu.edu.tw/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

tar -zxf zookeeper-3.4.9.tar.gz

sudo mv zookeeper-3.4.9 /usr/local/zookeeper

sudo chown hadoop:hadoop /usr/local/zookeeper

sudo mkdir -p /usr/local/zookeeper/logs

修改 /etc/bash.bashrc

export ZOOKEEPER_HOME=/usr/local/zookeeper

export PATH=$PATH:$ZOOKEEPER_HOME/bin

重新載入 bash.bashrc

source /etc/bash.bashrc

修改 zoo.cfg

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/usr/local/zookeeper

clientPort=2181

dataLogDir=/usr/local/zookeeper/logs

server.1=master:2888:3888

server.2=slave01:2888:3888

server.3=slave02:2888:3888

server.4=slave03:2888:3888

重要：1、2、3、4 對應 myid 中的編號

設定主機 myid 編號

master:

sudo echo "1" > /usr/local/zookeeper/myid

slave01:

sudo echo "2" > /usr/local/zookeeper/myid

slave02:

sudo echo "3" > /usr/local/zookeeper/myid

slave03:

sudo echo "4" > /usr/local/zookeeper/myid

啟動

/usr/local/zookeeper/bin/zkServer.sh start

重新啟動 Zookeeper

/usr/local/zookeeper/bin/zkServer.sh restart 

停止

/usr/local/zookeeper/bin/zkServer.sh stop

狀態

/usr/local/zookeeper/bin/zkServer.sh status

測試資料夾寫入 Zookeeper

進入 Zookeeper command 模式

/usr/local/hadoop/zookeeper/bin/zkCli.sh -server 127.0.0.1:2181

建立一個名為 mytest1 的資料夾進 File system

create /mytest test

查看 /mytest 資料夾檔案

ls /
