源码包（下载这个比较麻烦，需要安装maven，然后mvn package进行编译）
https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/current/apache-zookeeper-3.5.6.tar.gz
部署
#安装jdk1.8
yum install -y java-1.8.0-openjdk
#部署zookeeper
tar xvzf apache-zookeeper-3.5.6-bin.tar.gz
mv apache-zookeeper-3.5.6-bin /opt
cd /opt/apache-zookeeper-3.5.6-bin/conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
修改
dataDir=/data/zookeeper
#该目录为数据保存目录
mkdir -p /data/zookeeper
cd /opt/apache-zookeeper-3.5.6-bin/
bin/zkServer.sh start
输出如下，STARTED表示成功。
ZooKeeper JMX enabled by default
Using config: /opt/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
连接测试
bin/zkCli.sh -server 127.0.0.1:2181
出现如下命令输入框则表示连接成功
WatchedEvent state:SyncConnected type:None path:null
[zk: 127.0.0.1:2181(CONNECTING) 0]
此时输入
ls /
可以查看zookeeper根目录有一个zookeeper文件：
[zk: 127.0.0.1:2181(CONNECTED) 2] ls /
[zookeeper]
