**在 [CentOS][]7 上安装 zookeeper-3.4.10 服务**

1、创建 /usr/local/services/zookeeper 文件夹：  
    mkdir -p /usr/local/services/zookeeper  
   
2、进入到 /usr/local/services/zookeeper 目录中：  
    cd /usr/local/services/zookeeper  
   
3、下载 zookeeper-3.4.10.tar.gz：  
    wget [http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz][http_mirrors.hust.edu.cn_apache_zookeeper_zookeeper-3.4.10_zookeeper-3.4.10.tar.gz]  
   
4、解压缩 zookeeper-3.4.10.tar.gz：  
    tar -zxvf zookeeper-3.4.10.tar.gz  
   
5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：  
    cd zookeeper-3.4.10/conf/  
   
6、复制 zoo\_sample.cfg 文件的并命名为为 zoo.cfg：  
    cp zoo\_sample.cfg zoo.cfg  
   
7、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=/usr/local/services/zookeeper/zookeeper-3.4.10/data  
   
    \# 日志文件夹  
    dataLogDir=/usr/local/services/zookeeper/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][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  
   
8、保存并关闭 zoo.cfg 文件:  
      
9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.10/bin 目录中：  
    cd ../bin/  
   
10、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：  
   
    \# idea - zookeeper-3.4.10 config start - 2016-09-08  
   
    export ZOOKEEPER\_HOME=/usr/local/services/zookeeper/zookeeper-3.4.10/  
    export PATH=$ZOOKEEPER\_HOME/bin:$PATH  
    export PATH  
   
    \# idea - zookeeper-3.4.10 config start - 2016-09-08  
   
11、使 /etc/ 目录下的 profile 文件即可生效：  
    source /etc/profile  
   
12、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: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg  
    Starting zookeeper ... STARTED  
   
13、查询 zookeeper 状态：  
    zkServer.sh status  
   
14、关闭 zookeeper 服务：  
    zkServer.sh stop  
    如打印如下信息则表明成功关闭：  
    ZooKeeper JMX enabled by default  
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg  
    Stopping zookeeper ... STOPPED  
   
15、重启 zookeeper 服务：  
    zkServer.sh restart  
    如打印如下信息则表明重启成功：  
    ZooKeeper JMX enabled by default  
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg  
    ZooKeeper JMX enabled by default  
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg  
    Stopping zookeeper ... STOPPED  
    ZooKeeper JMX enabled by default  
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg  
    Starting zookeeper ... STARTED
