下载地址https://downloads.apache.org/zookeeper/
下载apache-zookeeper-3.6.3-bin.tar.gz ，一定要下载带bin的否则 会报错错误: 找不到或无法加载主类org.apache.zookeeper.server.quorum.QuorumPeerMain
解压tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz
如果没有在在环境变量里面设置JAVA_HOME，则需要指定jdk安装位置：
在bin/zkEnv.sh的中开始位置添加JAVA_HOME
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk.x86_64
修改配置文件
进入conf文件夹，复制zoo_sample.cfg，改名为zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial?
# synchronization phase can take
initLimit=10

admin.serverPort=8087
server.1=10.0.2.242:2888:3888
server.2=10.0.2.243:2888:3888
server.3=10.0.2.244:2888:3888其中dataDir=/usr/local/cok/SFS2X/zookeeper/datas中datas需要新建一个文件夹来存放数据
admin.serverPort=8087指定zookeeper服务端口
server.1=ip:2888:3888
server.2=ip:2888:3888
server.3=ip:2888:3888
指集群里面的服务器IP，集群服务器间通信端口，服务器选举端口
在你新建的datas里面创建文件myid，文件内容为1，或者2，与server.1里面的数字对应
分别启动每台服务器的zookeeper服务
zkServer.sh start
停止服务
zkServer.sh stop
查看集群节点状态：
zkServer.sh status
?出现下面状态则集群启动成功
查看zookeeper日志：
在 logs文件夹下?zookeeper-root-server-localhost.out
记得开放需要的端口，防止服务器间端口访问不成功
