在 CentOS7 上安装 Zookeeper-3.4.14 服务

资源包

zookeeper-3.4.14.tar.gz
1、创建 /usr/local/services/zookeeper 文件夹：

  1. mkdir -p /usr/local/services/zookeeper

2、进入到 /usr/local/services/zookeeper 目录中：

  1. cd /usr/local/services/zookeeper


3、下载 zookeeper-3.4.14.tar.gz：

4、解压缩 zookeeper-3.4.14.tar.gz：

  1. tar -zxvf zookeeper-3.4.14.tar.gz


5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.14/conf 目录中：

  1. cd zookeeper-3.4.14/conf/

6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：

  1. cp zoo_sample.cfg zoo.cfg


7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：

  1.  # The number of milliseconds of each tick
  3.     # zookeeper 定义的基准时间间隔，单位：毫秒
  4.     tickTime=2000
  6.     # The number of ticks that the initial
  7.     # synchronization phase can take
  8.     initLimit=10
  9.     # The number of ticks that can pass between
  10.     # sending a request and getting an acknowledgement
  11.     syncLimit=5
  12.     # the directory where the snapshot is stored.
  13.     # do not use /tmp for storage, /tmp here is just
  14.     # example sakes.
  15.     # dataDir=/tmp/zookeeper
  17.     # 数据文件夹
  18.     dataDir=/usr/local/services/zookeeper/zookeeper-3.4.10/data
  20.     # 日志文件夹
  21.     dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.10/logs
  23.     # the port at which the clients will connect
  24.     # 客户端访问 zookeeper 的端口号
  25.     clientPort=2181
  27.     # the maximum number of client connections.
  28.     # increase this if you need to handle more clients
  29.     #maxClientCnxns=60
  30.     #
  31.     # Be sure to read the maintenance section of the
  32.     # administrator guide before turning on autopurge.
  33.     #
  34.     # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
  35.     #
  36.     # The number of snapshots to retain in dataDir
  37.     #autopurge.snapRetainCount=3
  38.     # Purge task interval in hours
  39.     # Set to "0" to disable auto purge feature
  40.     #autopurge.purgeInterval=1

8、保存并关闭 zoo.cfg 文件:

9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.14/bin 目录中：

  1. cd ../bin/


10、用 vim 打开 /etc/ 目录下的配置文件 profile：

  1. vim /etc/profile
  1. 并在其尾部追加如下内容：<br /> 
  1. export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.14/
  2. export PATH=$ZOOKEEPER_HOME/bin:$PATH
  3. export PATH

11、使 /etc/ 目录下的 profile 文件即可生效：

  1. 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-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper … STARTED

13、查询 zookeeper 状态：

  1. zkServer.sh status


14、关闭 zookeeper 服务：

  1. 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-3.4.14/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED

15、重启 zookeeper 服务：

  1. 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-3.4.14/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Stopping zookeeper … STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper … STARTED
