Zookeeper 環境配置

1 版本選擇

因為要和後面的hive kafka整合 所以選擇了 zookeeper-3.4.5-cdh5.10.0

2 檔案配置

1. 複製並修改配置檔案：

cp conf/zoo_sample.cfg conf/zoo.cfg
vi conf/zoo.cfg
-----------------------------------------------------
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
 

# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
#建立儲存資料目錄
dataDir=/opt/modules/zookeeper-3.4
 
.5-cdh5.10.0/zkData
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
 

#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
#叢集環境 id 及埠設定
server.1=bigdata01.com:2888:3888
server.2=bigdata02.com:2888:3888
server.3=bigdata03.com:2888:3888

1. 建立資料儲存目錄：

mkdir /opt/modules/zookeeper-3.4.5-cdh5.10.0/zkData

1. 在儲存目錄中建立myid 檔案 並修改檔案：

touch zkData/myid
vi zkData/myid
----------------------------------
#在這裡寫在剛才的叢集環境中的id
1

3 執行

要兩臺機器的Server啟動才能使用Zookeeper 因為它的是2N+1 N是可損壞的數量

bin/zkServer.sh start

4 測試

bin/zkServer.sh status 

出現一下資訊說明此節點是follower節點

JMX enabled by default
Using config: /opt/modules/zookeeper-3.4.5-cdh5.10.0/bin/../conf/zoo.cfg
Mode: follower

使用這個命令進入Client 端

bin/zkCli.sh 

可使用的命令有ls,get,create,delete,set
