上篇安装完成了hadoop，接下来安装zookeeper。

• 安装zookeeper        (2台机器配置基本相同）

  #!/bin/bash

  PATH_FILE="/etc/profile" #安装包路径 ZOOKEEPER_TAR="/home/hdp/Downloads/zookeeper-3.4.9.tar.gz" ZOOKEEPER_INSTALL_HOME="/usr/local"

  #安装zookeeper

  if [ -d $ZOOKEEPER_INSTALL_HOME/zookeeper ] then sudo rm -rf $ZOOKEEPER_INSTALL_HOME/zookeeper fi

  #解压zookeeper sudo tar -zxvf $ZOOKEEPER_TAR -C $ZOOKEEPER_INSTALL_HOME

  #修改文件名称 sudo mv $ZOOKEEPER_INSTALL_HOME/zookeeper-3.4.9 $ZOOKEEPER_INSTALL_HOME/zookeeper

  #将所有者修改为hadoop sudo chown -R hadoop $ZOOKEEPER_INSTALL_HOME/zookeeper

  #设置环境变量 if [ -z $ZOOKEEPER_HOME ]
  then sudo echo "export ZOOKEEPER_HOME="$ZOOKEEPER_INSTALL_HOME/zookeeper"" >> $PATH_FILE sudo echo "export PATH="${ZOOKEEPER_HOME}/bin:$PATH"" >> $PATH_FILE #刷新环境变量 source /etc/profile fi

• 配置

        修改/conf/zoo_sample.cfg文件名为 zoo.cfg.       

dataDir=/usr/local/zookeeper/data


server.0=d155:2888:3888
server.1=d156:2888:3888

     在/usr/local/zookeeper/ 目录 建立文件夹data

     然后在data文件夹下建立文件 myid

     文件内容: d155机器为0，d156机器为 1，分别对应（server.*）.

•      启动、停止

  hadoop@d155$/usr/local/zookeeper/bin/zkServer.sh start hadoop@d155$/usr/local/zookeeper/bin/zkServer.sh stop hadoop@d155$/usr/local/zookeeper/bin/zkServer.sh status
