linux系统安装zookeeper 服务的方法

linux系统安装zookeeper 服务的方法

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-3.4.9.tar.gz：

 wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz 

 4、解压缩 zookeeper-3.4.9.tar.gz： 

  tar -zxvf zookeeper-3.4.9.tar.gz

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

cd zookeeper-3.4.9/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-3.4.9/data
   # 日志文件夹
  dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/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:    

9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/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-3.4.9 config start - 2016-09-08
   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 - 2016-09-08

 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-3.4.9/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-3.4.9/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-3.4.9/bin/../conf/zoo.cfg
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Stopping zookeeper ... STOPPED
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Starting zookeeper ... STARTED
