ZooKeeper安装实例

获取zookeeper-3.4.9.tar.gz安装包：

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、解压缩 zookeeper-3.4.9.tar.gz：

拷贝文件zookeeper-3.4.9.tar.gz至/home/nriet/software目录下

# cp zookeeper-3.4.9.tar.gz/usr/local/services/zookeeper/

# tar -zxvf zookeeper-3.4.9.tar.gz

 

4、进入到/usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：

    #cd zookeeper-3.4.9/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 ofmilliseconds of each tick

 

    # zookeeper 定义的基准时间间隔，单位：毫秒

    tickTime=2000

 

    # The number ofticks that the initial

    #synchronization phase can take

    initLimit=10

    # The number ofticks that can pass between

    # sending arequest and getting an acknowledgement

    syncLimit=5

    # the directorywhere the snapshot is stored.

    # do not use/tmp for storage, /tmp here is just

    # examplesakes.

    #dataDir=/tmp/zookeeper

 

    # 数据文件夹

   dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data

 

    # 日志文件夹

   dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs

 

    # the port atwhich the clients will connect

    # 客户端访问 zookeeper 的端口号

    clientPort=2181

 

    # the maximumnumber of client connections.

    # increase thisif you need to handle more clients

   #maxClientCnxns=60

    #

    # Be sure toread the maintenance section of the

    # administratorguide before turning on autopurge.

    #

    #http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

    #

    # The number ofsnapshots to retain in dataDir

   #autopurge.snapRetainCount=3

    # Purge taskinterval 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/usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：

 

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：

 

    # idea -zookeeper-3.4.9 config start - 2017-11-01

    export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/

    export PATH=$ZOOKEEPER_HOME/bin:$PATH

    export PATH

    # idea -zookeeper-3.4.9 config start - 2017-11-01

 

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 JMXenabled by default

    Using config:/usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg

    Startingzookeeper ... STARTED

 

12、查询 zookeeper 状态：

# zkServer.sh status      

                        

13、关闭 zookeeper 服务：

    # zkServer.sh stop

    如打印如下信息则表明成功关闭：

    

 

14、重启 zookeeper 服务：

    # zkServer.sh restart

    如打印如下信息则表明重启成功：
