前言：本篇文章是學習spark的開篇，搭建一個spark的完全分布式叢集，與大家共勉。
1.将Spark解壓并上傳至/opt目錄下
tar -zxvf spark-1.6.2-bin-hadoop2.6.tgz -C /opt/
2.修改環境變量
vi /etc/profile
export SPARK_HOME=/opt/spark
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin
source /etc/profile
3.配置Spark-env.sh
a、cd /opt/spark/conf
b、cp spark-env.sh.template spark-env.sh
c、vi spark-env.sh
export JAVA_HOME=/opt/jdk
export SCALA_HOME=/opt/scala
export SPARK_MASTER_IP=master
export SPARK_MASTER_PORT=7077
export SPARK_WORKER_CORES=1
export SPARK_WORKER_INSTANCES=1
export SPARK_WORKER_MEMORY=3g
export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop
4.配置slaves
b、mv slaves.template slaves
c、vi slaves
master
slave01
slave02
5.啟動和驗證Spark
a、8080
b、spark-shell
