Zookeeper Installing the Windows environment

1. Overview

Zookeeper is a full-fledged sub-project of Hadoop, a reliable coordination system for large distributed systems, with features such as configuration maintenance, name services, distributed synchronization, group services, and more. The goal of zookeeper is to encapsulate complex and error-prone services that provide users with easy-to-use interfaces and performance-efficient, robust systems.

2. Installation & Configuration

The official website of Apache provides a lot of mirrors, then find the corresponding version, the latest is 3.3.6

：

Http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz

Install under Windows

Extract the downloaded zookeeper files to the specified directory

D:\machine\zookeeper-3.3.6>

Modify the Conf to add a zoo.cfg

The contents are as follows:

# The number of milliseconds of each tick heartbeat interval milliseconds each time

ticktime=2000

# The number of ticks that initial

# Synchronization phase can take

initlimit=10

# The number of ticks that can pass between

# Sending a request and getting anacknowledgement

Synclimit=5

# The directory where the snapshot isstored. Mirrored Data location

Datadir=d:\\data\\zookeeper

#日志位置

Datalogdir=d:\\logs\\zookeeper

# The port at which the clients WillConnect client connection

clientport=2181

Note: If you start an error message that the CFG file has errors, you can use the contents of the zoo_sample.cfg can also be replaced

Go to the Bin directory and start Zkserver.cmd, this script will start a Java process

D:\MACHINE\ZOOKEEPER-3.3.6>CD bin

D:\machine\zookeeper-3.3.6\bin>

D:\machine\zookeeper-3.3.6\bin >zkserver.cmd

After startup JPs can see the quorumpeermain process

D:\machine\zookeeper-3.3.6\bin >jps

Start the client run and see for yourself

D:\machine\zookeeper-3.3.6\bin>zkcli.cmd-server 127.0.0.1:2181

This time zookeeper has been installed successfully,

Refer to the official documentation:

Http://zookeeper.apache.org/doc/trunk/zookeeperStarted.html

Refer to single-machine mode, cluster, and pseudo-cluster posts

http://sqcjy111.iteye.com/blog/1741320

The Zkserver.cmd file can be modified on a single machine when it is running through a pseudo-cluster.

Set zoocfg=. \conf\zoo1.cfg this line, save as Zkserver-1.cmd

If you have more than one

Also need to be in the corresponding

/TMP/ZOOKEEPER/1,

/TMP/ZOOKEEPER/2,

/tmp/zookeeper/3

Create a text file named myID, and the content will be the corresponding ZOO.CFG server. Post-Digital
