1.进入/opt

cd /opt
2.下载 zookeeper-3.4.10.tar.gz：

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
3.解压缩 zookeeper-3.4.10.tar.gz： 

tar -zxvf zookeeper-3.4.10.tar.gz
4.进入到 /opt/zookeeper-3.4.10/conf 目录中：

cd zookeeper-3.4.10/conf/
5.复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：

cp zoo_sample.cfg zoo.cfg
6.用 vim 打开 zoo.cfg 文件并修改其内容为如下：
   
 # The number of milliseconds of each tick
 
    # zookeeper 定义的基准时间间隔，单位：毫秒
    tickTime=2000
 
    # The number of ticks that the initial
    # synchronization phase can take
    initLimit=10
    # The number of ticks that can pass between
    # sending a request and getting an acknowledgement
    syncLimit=5
    # the directory where the snapshot is stored.
    # do not use /tmp for storage, /tmp here is just
    # example sakes.
    # dataDir=/tmp/zookeeper
 
    # 数据文件夹
    dataDir=/opt/zookeeper-3.4.10/data
 
    # 日志文件夹
    dataLogDir=/opt/zookeeper-3.4.10/logs
 
    # the port at which the clients will connect
    # 客户端访问 zookeeper 的端口号
    clientPort=2181
 
    # the maximum number of client connections.
    # increase this if you need to handle more clients
    #maxClientCnxns=60
    #
    # Be sure to read the maintenance section of the
    # administrator guide before turning on autopurge.
    #
    # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
    #
    # The number of snapshots to retain in dataDir
    #autopurge.snapRetainCount=3
    # Purge task interval in hours
    # Set to "0" to disable auto purge feature
    #autopurge.purgeInterval=1
7.保存并关闭 zoo.cfg 文件:
     
8.进入到 /opt/zookeeper-3.4.10/bin 目录中：

 cd ../bin/
9.用 vim 打开 /etc/ 目录下的配置文件 profile：
    
vim /etc/profile
    并在其尾部追加如下内容：
    export ZOOKEEPER_HOME=/opt/zookeeper-3.4.10/
    export PATH=$ZOOKEEPER_HOME/bin:$PATH
    export PATH
10.使 /etc/ 目录下的 profile 文件即可生效：

 source /etc/profile
11.启动 zookeeper 服务： 

zkServer.sh start
如打印如下信息则表明启动成功：

ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
12.查询 zookeeper 状态：

 zkServer.sh status
13.关闭 zookeeper 服务：  

[root@localhost bin]# zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.10/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
14.重启 zookeeper 服务：

[root@localhost bin]# zkServer.sh restart
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.10/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.10/bin/../conf/zoo.cfg
Stopping zookeeper ... no zookeeper to stop (could not find file /opt/zookeeper-3.4.10/data/zookeeper_server.pid)
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
