如何在linux系统中安装zookeeper 服务

本篇文章为大家展示了如何在linux系统中安装zookeeper 服务，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

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

什么是Linux系统

Linux是一种免费使用和自由传播的类UNIX操作系统，是一个基于POSIX的多用户、多任务、支持多线程和多CPU的操作系统，使用Linux能运行主要的Unix工具软件、应用程序和网络协议。
