Centos7安裝zookeeper

1.進入/opt

cd /opt

2.下載 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.解壓縮 zookeeper- 3.4 .10 .tar.gz：  

tar -zxvf zookeeper-3.4.10.tar.gz

4.進入到 /opt/zookeeper- 3.4 . 10 /conf 目錄中：

cd zookeeper-3.4.10/conf/

5.復制 zoo_sample.cfg 文件的並命名為為 zoo.cfg：

cp zoo_sample.cfg zoo.cfg

6.用 vim 打開 zoo.cfg 文件並修改其內容為如下：

   

 # The number of milliseconds of each tick
 
    # zookeeper 定義的基准時間間隔，單位：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
 
    # 數據文件夾
    dataDir=/opt/zookeeper-3.4.10/data
 
    # 日志文件夾
    dataLogDir=/opt/zookeeper-3.4.10/logs
 
    # the port at which the clients will connect
    # 客戶端訪問 zookeeper 的端口號
    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.保存並關閉 zoo.cfg 文件:

     

8.進入到 /opt/zookeeper- 3.4 . 10 /bin 目錄中：

 cd ../bin/

9.用 vim 打開 /etc/ 目錄下的配置文件 profile：

    

vim /etc/profile
    並在其尾部追加如下內容：
    export ZOOKEEPER_HOME=/opt/zookeeper-3.4.10/
    export PATH=$ZOOKEEPER_HOME/bin:$PATH
    export PATH

10.使 /etc/ 目錄下的 profile 文件即可生效：

 source /etc/profile

11.啟動 zookeeper 服務：  

zkServer.sh start

如打印如下信息則表明啟動成功：

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

12.查詢 zookeeper 狀態：

 zkServer.sh status

13.關閉 zookeeper 服務：   

[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. 重啟 zookeeper 服務：

[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
