阿里雲ECS centos7 安裝zookeeper

一、建立 /usr/local/zookeeper 文件夾： mkdir -p /usr/local/zookeeper

二、進入到 /usr/local/zookeeper 目錄中： cd /usr/local/zookeeper

3.下載 zookeeper-3.5.3-beta.tar.gz wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.5.3-beta/zookeeper-3.5.3-beta.tar.gz

4.解壓縮 zookeeper-3.5.3-beta.tar.gz： tar -zxvf zookeeper-3.5.3-beta.tar.gz 解壓時遇到的問題，及解決方案：

gzip: stdin: not in gzip format
　　tar: Child returned status 1
　　tar: Error is not recoverable: exiting now

如今我提供一下我總結的解決方法：

方法一：

#tar -xvf zookeeper-3.5.3-beta.tar.gz

tar包壓縮的時候用cvf參數，解壓的時候用xvf參數 或壓縮的時候用czvf參數，解壓的時候用xzvf參數

五、進入到 /usr/local/zookeeper/zookeeper-3.5.3-beta/conf 目錄中： cd zookeeper-3.5.3-beta/conf/

六、複製 zoo_sample.cfg 文件的並命名爲爲 zoo.cfg： cp zoo_sample.cfg zoo.cfg

七、用 vim 打開 zoo.cfg 文件並修改其內容爲以下：

# The number of milliseconds of each tick
 
    # zookeeper 定義的基準時間間隔，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=/usr/local/zookeeper/zookeeper-3.5.3-beta/data
 
    # 日誌文件夾
    dataLogDir=/usr/local/zookeeper/zookeeper-3.5.3-beta/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

八、保存並關閉 zoo.cfg 文件:

九、用 vim 打開 /etc/ 目錄下的配置文件 profile： vim /etc/profile 並在其尾部追加以下內容：

export ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.5.3-beta
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH

十、使 /etc/ 目錄下的 profile 文件便可生效： source /etc/profile

十一、啓動 zookeeper 服務： zkServer.sh start 如打印以下信息則代表啓動成功：

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

十二、查詢 zookeeper 狀態： zkServer.sh status

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone

1三、關閉 zookeeper 服務： zkServer.sh stop 如打印以下信息則代表成功關閉：

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED

1四、重啓 zookeeper 服務： zkServer.sh restart 如打印以下信息則代表重啓成功：

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... no zookeeper to stop (could not find file /usr/local/zookeeper/zookeeper-3.5.3-beta/data/zookeeper_server.pid)
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.3-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
