環境準備 1. 準備三臺虛擬機器 2. 每臺機器上都安裝好jdk環境 3. 全網統一hosts對映配置 4. 關閉防火牆

上傳zookeeper安裝包

解壓

[root@hadoop05 local]# tar -zxvf zookeeper-3.4.6.tar.gz 
[root@hadoop05 local]# ln -s zookeeper-3.4.6 zookeeper  （建立軟連線）
[root@hadoop05 local]#

刪除多餘的檔案（可忽略）

[root@hadoop05 zookeeper]# rm -rf *.txt *.xml docs/ src/ dist-
 
maven/
[root@hadoop05 zookeeper]# ll

設定環境變數 注意：每臺zookeeper都需要修改

1. 開啟環境變數配置檔案

   [root@hadoop05 zookeeper]# vim /etc/profile
   [root@hadoop01 local]# 
   

2. 修改環境變數，在profile檔案中加入下面內容

   #set zookeeper enviroment
   export ZOOKEEPER_HOME=/usr/local/zookeeper     
   export PATH=$PATH:${ZOOKEEPER_HOME}/bin
    
   

3. 載入配置檔案,使之生效 source /etc/profile

修改Zookeeper配置檔案

[[email protected] conf]# cp zoo_sample.cfg  zoo.cfg 
[[email protected] conf]# vim zoo.cfg 

dataDir=/usr/local/zookeeper/zkdata
server.1=mini1:2888:3888     ## (心跳埠、選舉埠)
server.2=mini2:2888:3888
server.3=mini3:2888:3888

建立資料夾,並在該檔案下建立myid檔案

[[email protected] zookeeper]# mkdir zkdata
[[email protected] zookeeper]# cd zkdata/
[[email protected] zkdata]# echo 1 > myid
[[email protected] zkdata]# cat myid 
1
[[email protected] zkdata]# 

分發安裝包到其他機器

[[email protected] local]# scp -r /usr/local/zookeeper [email protected]:/usr/local/
[[email protected] local]# scp -r /usr/local/zookeeper [email protected]:/usr/local/
...

修改其他機器的配置檔案 hadoop06上修改myid為：2 hadoop07上修改myid為：3

啟動（每臺機器）

[[email protected] local]# zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[[email protected] local]# 

zookeeper叢集啟動指令碼

#!/bin/bash

for host in hadoop05 hadoop06 hadoop07
do
echo "$host zookeeper is starting..."
ssh $host "/usr/local/zookeeper/bin/zkServer.sh  start"
done
