centos7 安装 zookeeper

zookeeper官网获取下载 http://www.apache.org/dyn/closer.cgi/zookeeper/

• 使用wget命令下载
  wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.5/apache-zookeeper-3.5.5.tar.gz
• 解压命令
  tar zxvf apache-zookeeper-3.5.5.tar.gz
• 修改目录名
   mv apache-zookeeper-3.5.5 zookeeper-3.5.5
• 进入到/usr/local/zookeeper-3.5.5/conf 目录
  cd /usr/local/zookeeper-3.5.5/conf
• 复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg
  cp zoo_sample.cfg zoo.cfg
• 用 vi 打开 zoo.cfg 文件并修改其内容为如下
  vi zoo.cfg

  # The number of milliseconds of each tick
  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
  #data dir
  dataDir=/usr/local/zookeeper-3.5.5/data
  #log dir
  dataLogDir=/usr/local/zookeeper-3.5.5/logs
  # the port at which the clients will connect
  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

• 增加环境变量，在 /etc/profile文件尾部增加内容
  vi /etc/profile

export ZOOKEEPER_HOME=/usr/local/zookeeper-3.5.5
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH

• 使配置生效命令
  source /etc/profile
• 启动zookeeper
  cd /usr/local/zookeeper-3.5.5/bin
  zkServer.sh start

打印如下信息表示成功

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.5.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

• 查询 zookeeper 状态
  zkServer.sh status

• 关闭 zookeeper 服务：
  zkServer.sh stop 
• 重启 zookeeper 服务
  zkServer.sh restart
