本文详细介绍了Zookeeper集群的搭建过程，包括节点主机配置、环境变量设置、配置文件修改及myid文件创建等关键步骤，适合初学者快速上手。

						zookeeper集群搭建

1、节点主机
node02
node03
node04
2、解压zookeeper.3.4.6.tar.gz到/opt/zookeeper.3.4.6下
tar -zxvf zookeeper.3.4.6.tar.gz -C /opt
3、进入zookeeper的安装文件夹
cd /opt/zookeeper.3.4.6
创建zookeeper的存放数据的文件夹
mkdir data
4、配置zookeeper的环境变量
vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_181
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export ZOOKEEPER_HOME=/opt/zookeeper.3.4.6
export PATH=$PATH:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin

通过scp命令分发到node03和node04
scp -p /etc/profile root@node03:/etc/profile
5、修改配置文件
cd /opt/zookeeper.3.4.6/conf
先把zoo_sample.cfg改为zoo.cfg
mv zoo_sample.cfg zoo.cfg

# 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/zookeeper.3.4.6/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
server.1=node02:2888:3888
server.2=node03:2888:3888
server.3=node04:2888:3888

6、分发zookeeper到node03和node04
scp -r /opt/zookeeper.3.4.6 root@node03:/opt
scp -r /opt/zookeeper.3.4.6 root@node04:/opt
7、创建myid文件
server.1=node02:2888:3888
server.2=node03:2888:3888
server.3=node04:2888:3888
根据上面server.(id)中的id号,在zookeeper存放数据的文件夹创建myid文件
cd /opt/zookeeper.3.4.6/data
echo “1” > myid node02
echo “2” > myid node03
echo “3” > myid node04
8、zkServer.sh start启动zookeeper
zkServer.sh status可以查看zookeeper运行状态
