将Zookeeper上传到节点1 ![[Pasted image 20251019144436.png]]

配置环境变量

解压到moduels中

tar -zxvf zookeeper-3.4.6.tar.gz -C /opt/modules/
chown -R hadoop:hadoop /opt/modules/zookeeper-3.4.6

添加到环境

export ZOOKEEPER_HOME=/opt/modules/zookeeper-3.4.6
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$JRE_HOME/bin:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf

sudo scp /etc/profile root@gyy2:/etc/
sudo scp /etc/profile root@gyy3:/etc/

source /etc/profile

配置Zookeeper

在主节点执行：

cd /opt/modules/zookeeper-3.4.6/conf/
cp zoo_sample.cfg zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/modules/apache-zookeeper-3.6.4-bin/data
dataLogDir=/opt/modules/apache-zookeeper-3.6.4-bin/log
clientPort=2181

server.1=gyy1:2888:3888
server.2=gyy2:2888:3888
server.3=gyy3:2888:3888

mkdir /opt/modules/zookeeper-3.4.6/data /opt/modules/zookeeper-3.4.6/log

chown -R hadoop:hadoop /opt/modules/zookeeper-3.4.6

scp -r /opt/modules/zookeeper-3.4.6/ hadoop@gyy2:/opt/modules/
scp -r /opt/modules/zookeeper-3.4.6/ hadoop@gyy3:/opt/modules/

# NN1


<NolebasePageProperties />




echo "1" > /opt/modules/zookeeper-3.4.6/data/myid

# DN1
echo "2" > /opt/modules/zookeeper-3.4.6/data/myid

# DN2
echo "3" > /opt/modules/zookeeper-3.4.6/data/myid

在三个机器上执行

zkServer.sh start

在三个机器上查看状态

zkServer.sh status

主节点提示：

[hadoop@gyy1 ~]$ zkServer.sh status
JMX enabled by default
Using config: /opt/modules/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: follower

从节点提示：

[hadoop@gyy3 ~]$ zkServer.sh status
JMX enabled by default
Using config: /opt/modules/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: leader
