zookeeper的安装

Posted 2022-12-03 慧强杨

1、zookeeper的下载

官网下载地址 https://zookeeper.apache.org/releases.html
下载到本地

2、zookeeper的安装

下载后解压文件：如zookeeper-3.4.6
开始安装：

1、进入zookeeper-3.4.6\\conf路径下将zoo_example.cfg文件改名为zoo.cfg
2、修改zoo.cfg中的内容为

# 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=D:\\\\software\\\\zookeeper-3.4.6\\\\data
dataLogDir=D:\\\\software\\\\zookeeper-3.4.6\\\\log 
# the port at which the clients will connect
clientPort=2181
#
# 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、需要注意的地方是

dataDir=D:\\\\software\\\\zookeeper-3.4.6\\\\data
dataLogDir=D:\\\\software\\\\zookeeper-3.4.6\\\\log 
clientPort=2181

4、启动zookeeper,bin/zkServer.cmd双击打开
5、启动zkCli.cmd，测试是否安装成功

安装过程中遇到的问题：zkServer启动一闪而过：原因分析：1、没有修改zoo.cfg文件；2、修改文件后没有在本地创建data,log两个目录。
