Win10 stand-alone installation Zookeeper pseudo cluster
Installation process
1. Download
https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/stable/
The latest 3.5.5.bin.tar.gz decompression conflict, do not know why, or the next version 3.4.9:
http://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/
2. Extract to "D: \ programGreen \ zookeeper-3.4.9"
3. Modify the "zoo_sample.cfg" as "zoo.cfg"
Stand-alone mode
Run directly
- D:\programGreen\zookeeper-3.4.9\bin>zkServer.cmd

3.3 cmd windows were run three zkserverX.cmd, netstar-ano view port listening situation. - seemingly can not monitor it;
4.3 cmd window run zkCli.cmd
- zkCli.cmd -server:localhost:2181;
- zkCli.cmd -server:localhost:2182;
- zkCli.cmd -server:localhost:2183;

5. In the black box input commands zkCli.cmd
- ls / ------- View znode
- create / zk_test my_data ------- create znode
- ls / ------- znode more zk_test,
- get / zk_test ------- see the value my_data
- set / zk_test junk ------- is disposed junk
- get / zk_test ------- see is junk
- delete / zk_test ------- delete znode

Parameter Meaning
- dataDir: storage memory database snapshot location, as well as updates to the database transaction log (unless otherwise specified).
- dataLogDir: transaction log directory. ------ set this parameter may get lower latency update
- tickTime: unit time, in milliseconds.
- initLimit: When starting follower leader synchronization data from the completion time of the initial state; or follower must be connected to the leader of time, otherwise the follower will be rejected, on which the client is assigned to the other follower. ----- Under normal circumstances, we do not care too much about setting this parameter. If the amount of data clusters is large, it is necessary to properly turn up.
- clientPort: listening port for client connections.
- syncLimit: limit the extent of obsolete between the server and the leader. For example, leader issued a heartbeat packets but no response is received within the specified time, it is believed follower does not exist. Do not take this parameter is set too high, otherwise it may mask some problems.
- server.x = host: port1: port2. myid x digital files with the same id, port1 for inter-machine communications, port2 for elections.
