1. Zookeeper下載安裝
我的環境使用的套件版本是cdh5.7，所以zookeeper也選擇對應的版本下載。

[[email protected] software]$ wget http://archive.cloudera.com/cdh5/cdh/5/zookeeper-3.4.5-cdh5.7.0.tar.gz
[[email protected] software]$ tar -zxvf zookeeper-3.4.5-cdh5.7.0.tar.gz -C ~/app/配置環境變數
[[email protected] yum.repos.d]# vi /etc/profile
export ZK_HOME=/home/hadoop/app/zookeeper-3.4.5-cdh5.7.0
export PATH=$ZK_HOME/bin:$PATH
[ 修改zookeeper配置
