zookeeper配置集群

  zookeeper单点启动默认模式

  Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg
  Mode: standalone

 

  配置集群

  server.A=192.168.239.128:2888:3888

  server.A=192.168.239.129:2888:3888

  server.A=192.168.239.131:2888:3888

  .......................................................

  注意:最好保持奇数台服务器,以及配置最好放到一个git仓库中管理.

  另:2台服务是无法选举出Leader,最少三台服务器.

 

  创建myid

  dataDir=/opt/zookeeper/data创建一个文件myid,里面的内容与A对应

  [root@localhost zookeeper-3.4.9]# ./bin/zkServer.sh status
  ZooKeeper JMX enabled by default
  Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg
  Mode: leader

  [root@localhost zookeeper-3.4.9]# ./bin/zkServer.sh status
  ZooKeeper JMX enabled by default
  Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg
  Mode: follower
