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
