下载安装
wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz
解压：
tar -zxvf zookeeper-3.4.13.tar.gz
把名字改短一些
mv zookeeper-3.4.13 /usr/local/apps/zookeeper
配置环境变量：
vi /etc/profile
在配置文件中添加：export ZOOKEEPER_HOME=/usr/local/apps/zookeeperexport PATH=$PATH:$ZOOKEEPER_HOME/bin
复制一份zoo_sample.cfg并改名为zoo.cfg
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg 查看配置
