在 CentOS7.4 上安装 zookeeper-3.4.14 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-3.4.14.tar.gz： ####

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

#### 4、解压缩 zookeeper-3.4.14.tar.gz： ####

tar -zxvf zookeeper-3.4.14.tar.gz

#### 5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.14/conf 目录中： ####

cd zookeeper-3.4.14/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-3.4.14/data
    
    # 日志文件夹
    dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.14/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

#### 8、保存并关闭 zoo.cfg 文件: ####

:wq

#### 9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.14/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-3.4.14 config start - 2019-09-08
    
    export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.14/
    export PATH=$ZOOKEEPER_HOME/bin:$PATH
    export PATH
    
    # idea - zookeeper-3.4.14 config start - 2019-09-08

#### 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-3.4.14/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-3.4.14/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-3.4.14/bin/../conf/zoo.cfg
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
        Stopping zookeeper ... STOPPED
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
        Starting zookeeper ... STARTED
