参考

https://zookeeper.apache.org/doc/r3.4.13/zookeeperStarted.html

说明

zookeeper是java语言。
一个jar包。所以无需安装。

步骤

1.下载 解压缩

目录结构

2.修改配置文件

tickTime=2000
dataDir=/Users/gongzhihao/zookeeper
clientPort=2181

原始内容

# The number of milliseconds of each tick
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 an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

3.启动服务器和启动客户端

gongzhihaodeMacBook-Pro:zookeeper-3.4.13 gongzhihao$ bin/zkServer.sh start //启动服务器
