1.zookeeper單機搭建
- 下載:wget http://mirrors.shu.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz
- 解壓:tar -zxvf zookeeper-3.4.12.tar.gz
- 配置檔案:在conf目錄下刪除zoo_sample.cfg檔案,建立一個配置檔案zoo.cfg
tickTime=2000 dataDir=/usr/local/services/zookeeper/zk/data dataLogDir=/usr/local/services/zookeeper/zk/dataLog clientPort=2181
- 配置環境變數:在/etc/profile檔案中加入如下內容:
export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zk
export PATH=.:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$JAVA_HOME/bin:$PATH
- 啟動:啟動:zkServer.sh start;關閉:zkServer.sh stop
2.zookeeper單機偽叢集搭建
在zk目錄下新建data_1,data_2,data_3目錄,分別新建myid檔案,並分別寫入1,2,3
在conf目錄下新建zoo1.cfg,zoo2.cfg,zoo3.cfg

依次啟動三個服務:
