为学习spark，虚拟机中开4台虚拟机安装spark3.0.0

底层hadoop集群已经安装好，见ol7.7安装部署4节点hadoop 3.2.1分布式集群学习环境

首先，去http://spark.apache.org/downloads.html下载对应安装包

解压

[hadoop@master ~]$ sudo tar -zxf spark-3.0.0-bin-without-hadoop.tgz -C /usr/local
[hadoop@master ~]$ cd /usr/local
[hadoop@master /usr/local]$ sudo mv ./spark-3.0.0-bin-without-hadoop/ spark
[hadoop@master /usr/local]$ sudo chown -R hadoop: ./spark

四个节点都添加环境变量

export SPARK_HOME=/usr/local/spark
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin

配置spark

spark目录中的conf目录下cp ./conf/spark-env.sh.template ./conf/spark-env.sh后面添加

export SPARK_MASTER_IP=192.168.168.11
export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
export SPARK_LOCAL_DIRS=/usr/local/hadoop
export SPARK_DIST_CLASSPATH=$(/usr/local/hadoop/bin/hadoop classpath)

然后配置work节点，cp ./conf/slaves.template ./conf/slaves修改为

master
slave1
slave2
slave3

写死JAVA_HOME，sbin/spark-config.sh最后添加

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_191

复制spark目录到其他节点

sudo scp -r /usr/local/spark/ slave1:/usr/local/
sudo scp -r /usr/local/spark/ slave2:/usr/local/
sudo scp -r /usr/local/spark/ slave3:/usr/local/
sudo chown -R hadoop ./spark/

...

启动集群

先启动hadoop集群/usr/local/hadoop/sbin/start-all.sh

然后启动spark集群
