1、下载安装包

官方下载地址：https://archive.apache.org/dist/zookeeper/

网盘下载地址：https://pan.baidu.com/s/1j6iy5bZkrY-GKGItenRB2w?pwd=irrx 提取码: irrx

2、解压并添加环境变量

# 将安装包移动到目标目录
mv ~/Download/zookeeper-3.4.6.tar.gz /opt/module
# 进入目标目录
cd /opt/module
# 解压安装包
tar -zxvf zookeeper-3.4.6.tar.gz
# 修改目录名称
mv zookeeper-3.4.6 zookeeper
# 进入软件目录
cd zookeeper
# 创建data目录
mkdir data

#添加环境变量

sudo vim /etc/profile

export JAVA8_HOME="/Library/Java/JavaVirtualMachines/jdk8/Contents/Home"
alias java8="export JAVA_HOME=$JAVA8_HOME"

export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export MAVEN_HOME="/Library/Java/apache-maven-3.8.8"

export ZOOKEEPER_HOME=/opt/module/zookeeper
export PATH="$JAVA_HOME/bin:$MYSQL_HOME/bin:$MAVEN_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH:."

3、修改配置文件 

cd conf

cp zoo_sample.cfg zoo.cfg

以下是zoo.cfg的内容

# 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=/opt/module/zookeeper/data
# 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

 4、启动

cd ..

./bin/zkServer.sh start

# 查看进程是否存在
jps

# 如存在如下进程名表示启动了
QuorumPeerMain

5、检查是否成功

./bin/zkCli.sh

 成功后可以查看根节点、创建子节点等
