Brief introduction
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.
- Installation and 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:\ant\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-connected ports
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
You can also double-click Zkserver.cmd to start:
