一、描述
伪分布式集群就是在一台机器部署多个zk应用，部署之前服务器需要有jdk环境 java -version可以显示相关java信息才可以进行zookeeper搭建
二.步骤

第一步下载好zookeeper-3.4.9.tar.gz
然后解压 tar zxvf zookeeper-3.4.9.tar.gz
这里写图片描述
进入zk中的conf目录下输入cp zoo-sample.cfg zoo1.cfg cp zoo-sample.cfg zoo2.cfg、cp zoo-sample.cfg zoo3.cfg
分别对zoo1、2、3文件进行编辑

  1. # The number of milliseconds of each tick
  2. tickTime=2000
  3. # The number of ticks that the initial 
  4. # synchronization phase can take
  5. initLimit=10
  6. # The number of ticks that can pass between 
  7. # sending a request and getting an acknowledgement
  8. syncLimit=5
  9. # the directory where the snapshot is stored.
  10. # do not use /tmp for storage, /tmp here is just 
  11. # example sakes.
  12. dataDir=/apps/servers/data/d_1
  13. dataLogDir=/apps/servers/logs/logs_1
  14. # the port at which the clients will connect
  15. clientPort=2181 
  16. #不同zoo.cfg修改自己的属性和端口号
  17. # the maximum number of client connections.
  18. # increase this if you need to handle more clients
  19. #maxClientCnxns=60
  20. #
  21. # Be sure to read the maintenance section of the 
  22. # administrator guide before turning on autopurge.
  23. #
  24. # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
  25. #
  26. # The number of snapshots to retain in dataDir
  27. #autopurge.snapRetainCount=3
  28. # Purge task interval in hours
  29. # Set to "0" to disable auto purge feature
  30. #autopurge.purgeInterval=1
  31. server.1=localhost:2187:2887 
  32. server.2=localhost:2188:2888
  33. server.3=localhost:2189:2889

修改之后分别创建data目录和日志目录

  1. mkdir /apps/servers/data/d_1
  2. Mkdir /apps/servers/data/d_1
  3. mkdir /apps/servers/data/d_1
  5. mkdir /apps/servers/logs/logs_1
  6. mkdir /apps/servers/logs/logs_1
  7. mkdir /apps/servers/logs/logs_1
  9. echo "1" > /apps/servers/data/d_1/myid
  10. echo "2" >/apps/servers/data/d_2/myid
  11. echo "3" >/apps/servers/data/d_3/myid

进入bin目录下输入命令 分别进行启动

  1. zkServer.sh start ../conf/zoo1.cfg
  2. zkServer.sh start ../conf/zoo2.cfg
  3. zkServer.sh start ../conf/zoo3.cfg

通过命令检测是否成功：

  1. zkCli.sh -server localhost:2181, 
  2. localhost:2182, localhost:2183 是否可以连接成功
