ol7.7安裝部署4節點spark3.0.0分散式集群

為學習spark，虛擬機中開4台虛擬機安裝spark3.0.0

底層hadoop集群已經安裝好，見ol7.7安裝部署4節點hadoop 3.2.1分散式集群學習環境

首先，去http://spark.apache.org/downloads.html下載對應安裝包

解壓

[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

四個節點都添加環境變數

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

配置spark

spark目錄中的conf目錄下cp ./conf/spark-env.sh.template ./conf/spark-env.sh後面添加

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)

然後配置work節點，cp ./conf/slaves.template ./conf/slaves修改為

master
slave1
slave2
slave3

寫死JAVA_HOME，sbin/spark-config.sh最後添加

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

複製spark目錄到其他節點

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/

...

啟動集群

先啟動hadoop集群/usr/local/hadoop/sbin/start-all.sh

然後啟動spark集群

通過master8080埠監控

完成安裝
