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\"" >> $PATH_FILE
#刷新环境变量
source /etc/profile
fi
- 配置
修改/conf/zoo_sample.cfg文件名为zoo.cfg.
dataDir=/usr/local/zookeeper/data server.0=d155:2888:3888 server.1=d156:2888:3888
在/usr/local/zookeeper/ 目录 建立文件夹data
文件内容: d155机器为0，d156机器为 1，分别对应（server.*）.
- 启动、停止
hadoop@d155$/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
