基于Centos7搭建双节点Spark大数据平台

前提条件

在搭建好hadoop平台的基础上进行搭建，参看之前文章。

spark大数据平台的搭建

master节点

解压spark的安装包

#tar -zxvf /root/spark-3.1.3-bin-hadoop3.2.tgz -C /usr/local/

修改配置文件

①spark-env.sh

#cd /usr/local/spark-3.1.3-bin-hadoop3.2/conf

#cp spark-env.sh.template spark-env.sh

#vi spark-env.sh

最后添加9行内容即可。

export JAVA_HOME=/usr/local/jdk64/jdk1.8.0_321

export HADOOP_CONF_DIR=/usr/local/hadoop-3.2.2/etc/hadoop/

export SPARK_MASTER_IP=master

export SPARK_MASTER_PORT=7077

export SPARK_WORKER_MEMORY=512m

export SPARK_WORKER_CORES=1

export SPARK_WORKER_INSTANCES=1

export SPARK_EXECUTOR_MEMORY=512m

export SPARK_EXECUTOR_CORES=1

②workers

#cp workers.template workers

#vi workers

把localhost改成slave1

slave1

③spark-defalt.conf

#cp spark-defaults.conf.template spark-defaults.conf

#vi spark-defaults.conf

最后添加以下内容。

spark.master spark://master:7077

spark.eventLog.enabled true

spark.eventLog.dir hdfs://master:8020/spark-logs

spark.history.fs.logDirectory hdfs://master:8020/spark-logs

把master节点上spark的安装内容复制到slave1上即可。

#scp -r /usr/local/spark-3.1.3-bin-hadoop3.2/ slave1:/usr/local/

在hdfs上创建目录

#hdfs dfs -mkdir /spark-logs

启动spark集群。

#/usr/local/spark-3.1.3-bin-hadoop3.2/sbin/start-all.sh

验证：

http://192.168.200.100:8080

启动spark shell

# /usr/local/spark-3.1.3-bin-hadoop3.2/bin

#./spark-shell
