CentOS下安裝zookeeper

Linux下安裝Zookeeper叢集步驟

(1) 下載zookeeper安裝包

　　地址：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

(2) 解壓安裝包並放置在對應的路徑下

　　解壓對應檔案到對應的路徑下，本文將zookeeper解壓到/soft/zk路徑下，並在zk路徑下建立 dataDir與dataLogDir路徑

　　cd /soft/zk

　　tar -xvf zookeeper-xxx.tar.gz

　　mkdir dataDir

　　mkdir dataLogDir

 

(3) 配置zookeeper的設定檔

　　對zookeeper進行配置

　　cd /soft/zk/zookeeper-xxx/conf

　　cp zoo-sample.cfg zoo.cfg

　　vim zoo.cfg

　　

# The number of milliseconds of each tick
tickTime=2000# The number of ticks that the initial# synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just# example sakes.dataDir=/soft/zk/dataDirdataLogDir=/soft/zk/dataLogDir# the port at which the clients will connectclientPort=2181server.1=192.168.1.111:2888:3888server.2=192.168.1.112:2888:3888server.3=192.168.1.113:2888:3888

這裡對zookeeper伺服器進行配置，這裡需要將myid與對應的伺服器編號對應

 

(4) 設定zookeeper對應的myid檔案

　　cd /soft/zk/dataDir

　　vim myid

　　將伺服器編號放入

 

(5) 啟動zookeeper服務

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh start

　　啟動服務，注意查看zookeeper.out這個日誌輸出，可以看到問題點

 

(6) 驗證zookeeper是否正常啟動

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh status

　　sh zkCli.sh -server 192.168.1.111:2181

 

(7) 查詢zookeeper伺服器對應的主從關係狀態

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh status
