Zookeeper集群搭建-蒲公英云

Zookeeper集群搭建

引言

在搭建Zookeeper集群之前，需要有以下的一些准备工作

三个节点（因为在Zookeeper服务器集群中规模是不小于三个节点）
Linux虚拟机

一、准备Zookeeper的压缩包

https://zookeeper.apache.org/ 可以通过这个网址获取到对应的zookeeper-tar.gz压缩包

二、解压缩对应的压缩包

$ tar -zxvf zookeeper-tar.gz

三、配置环境变量

在用户目录下使用

vim .bash_profile

加入如下内容

export ZOOKEEPER_HOME=/home/hadoop/zookeeper
export JAVA_HOME=/home/hadoop/jdk1.8.0_161
export HADOOP_NOME=/home/hadoop/hadoop-2.8.5
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin:$HADOOP_NOME/bin:$ZOOKEEPER_HOME/bin
export PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH:$HOME/bin

四、修改Zookeeper的配置文件

在这里插入图片描述
如目录所示

cd zookeeper/conf

对于默认的.cfg文件进行重命名

mv zoo_sample.cfg zoo.cfg

在这里插入图片描述

五、修改配置文件内容

# 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=/home/hadoop/zookeeper/data
# 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
server.0=192.168.70.192:2888:3888
server.1=192.168.70.189:2888:3888
server.2=192.168.70.193:2888:3888

主要修改的是

dataDir=/home/hadoop/zookeeper/data
clientPort=2181
增加内容
server.0=192.168.70.192:2888:3888
server.1=192.168.70.189:2888:3888
server.2=192.168.70.193:2888:3888
