Apache ZooKeeper is an effort to develop and maintain an open-source server which enables highly reliable distributed coordination.
Download
Download the zookeeper, unzip it.
or
$ wget http://apache.fayea.com/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
Add Server1
- Add
server1package
$ cd /Users/houbinbin/it/tools/zookeeper/server1
$ ls
data logs zookeeper-3.4.9
- Add file
myid
add file myid in data package, and it’s content is
1
- Edit zookeeper-3.4.9/conf
$ /Users/houbinbin/it/tools/zookeeper/server1/zookeeper-3.4.9/conf
$ ls
configuration.xsl log4j.properties zoo_sample.cfg
$ cp zoo_sample.cfg zoo.cfg
- Edit the
zoo.cfg
add these content
# the data and log dir
dataDir=/Users/houbinbin/it/tools/zookeeper/server1/data
dataLogDir=/Users/houbinbin/it/tools/zookeeper/server1/logs
# the port at which the clients will connect
clientPort=2181
Add server2
If you want to test Cluster manager in one PC, you can do it like this:
server2 is the same as server1.
- Then, edit
zoo.cfg
# the data and log dir
dataDir=/Users/houbinbin/it/tools/zookeeper/server2/data
dataLogDir=/Users/houbinbin/it/tools/zookeeper/server2/logs
# the port at which the clients will connect
clientPort=2182
- Add file
myid
with the content of
2

一、下载并解压
(win7)
当前解压路径为 D:Learnapachezookeeperzookeeper-3.4.6
二、配置
在 conf 文件夹下添加配置文件，如果启动有报错提示cfg文件有错误，可以用 zoo_sample.cfg 内容替代
zoo.cfg
# The number of milliseconds of each tick 心跳间隔 毫秒每次
tickTime=2000
# The number of ticks that the 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. //镜像数据位置
dataDir=D:\Learn\apache\zookeeper\data
#日志位置
dataLogDir=D:\Learn\apache\zookeeper\log
# the port at which the clients willconnect 客户端连接的端口
clientPort=2181
三、运行
[D:Learnapachezookeeperzookeeper-3.4.6bin]$ zkServer.cmd
