阿里云ECS centos7 安装zookeeper

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

二、进入到 /usr/local/zookeeper 目录中： cd /usr/local/zookeeper

3.下载 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.解压缩 zookeeper-3.5.3-beta.tar.gz： tar -zxvf zookeeper-3.5.3-beta.tar.gz 解压时遇到的问题，及解决方案：

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

如今我提供一下我总结的解决方法：

方法一：

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

tar包压缩的时候用cvf参数，解压的时候用xvf参数 或压缩的时候用czvf参数，解压的时候用xzvf参数

五、进入到 /usr/local/zookeeper/zookeeper-3.5.3-beta/conf 目录中： cd zookeeper-3.5.3-beta/conf/

六、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg： cp zoo_sample.cfg zoo.cfg

七、用 vim 打开 zoo.cfg 文件并修改其内容为以下：

# 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/zookeeper/zookeeper-3.5.3-beta/data
 
    # 日志文件夹
    dataLogDir=/usr/local/zookeeper/zookeeper-3.5.3-beta/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

八、保存并关闭 zoo.cfg 文件:

九、用 vim 打开 /etc/ 目录下的配置文件 profile： vim /etc/profile 并在其尾部追加以下内容：

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

十、使 /etc/ 目录下的 profile 文件便可生效： source /etc/profile

十一、启动 zookeeper 服务： zkServer.sh start 如打印以下信息则代表启动成功：

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

十二、查询 zookeeper 状态： 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、关闭 zookeeper 服务： zkServer.sh stop 如打印以下信息则代表成功关闭：

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

1四、重启 zookeeper 服务： zkServer.sh restart 如打印以下信息则代表重启成功：

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
