单机
下载完成后，将安装包上传值服务器，解压
tar xvzf zookeeper-3.4.6.tar.gz进入解压后的目录
cd zookeeper-3.4.6
创建data,logs目录
mkdri data
mkdri logs
找到conf文件夹，进去
cd conf拷贝一份 zoo_sample.cfg到 zoo.cfg
cp zoo_sample.cfg zoo.cfg编辑zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/zookeeper-3.4.6/data
dataLogDir=/zookeeper-3.4.6/logs
clientPort=2181
cd /zookeeper-3.4.6/bin
./zkServer.sh start
./zkServer.sh status （查看状态）
./zkServer.sh stop（关闭）
集群
$ cd zookeeper-3.4.6/conf
$ cp zoo_sample.cfg zoo.cfg
$ vi zoo.cfg

在刚才创建的data文件夹地下创建myid文件
$ vi myid
各节点myid文件内容如下
192.168.192.11:

192.168.192.12:

192.168.192.13:

各节点分别启动zookeeper
$ cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin
$ ./zkServer.sh start
$ ./zkServer.sh status （查看状态）
$ ./zkServer.sh stop（关闭）- 1

我这里写了各小脚本，方便在Master直接调用脚本启动Zookeeper和关闭Zookeeper
启动脚本如下：
#!/bin/bash
cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin
./zkServer.sh start
ssh -tt hadoop@192.168.192.12 > /dev/null 2>&1 << remotessh
cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin
./zkServer.sh start
exit
remotessh
ssh -tt hadoop@192.168.192.13 > /dev/null 2>&1 << remotessh
cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin
./zkServer.sh start
exit
remotessh- 1

cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin/
./zkServer.sh stop
exit
remotessh
ssh -tt hadoop@192.168.192.13 > /dev/null 2>&1 << remotessh
cd /home/hadoop/zookeeper/zookeeper-3.4.6/bin/
./zkServer.sh stop
exit
remotessh- 1

注：使用脚本时，请先赋予脚本权限以及注意脚本文件格式
$ sudo chmod 777 脚本名称.sh- 1
出现：
/bin/bash^M: bad interpreter: No such file or dire
在执行shell脚本时提示这样的错误主要是由于shell脚本文件是dos格式，即每一行结尾以
来标识，而unix格式的文件行尾则以
来标识。 查看脚本文件是dos格式还是unix格式的几种办法。
（1）cat -A filename 从显示结果可以判断，dos格式的文件行尾为^M，unix格式的文件行尾为。
（2）od -t x1 filename 如果看到输出内容中存在0d 0a的字符，那么文件是dos格式，如果只有0a，则是unix格式。
（3）vi filename打开文件，执行 : set ff，如果文件为dos格式在显示为fileformat=dos，如果是unxi则显示为fileformat=unix。
解决方法：
（1）使用linux命令dos2unix filename，直接把文件转换为unix格式
（2）使用sed命令sed -i “s/
//” filename 或者 sed -i “s/^M//” filename直接替换结尾符为unix格式
（3）vi filename打开文件，执行 : set ff=unix 设置文件为unix，然后执行:wq，保存成unix格式。
