slave2 192.168.1.101

下载安装包：

# Master
wget http://archive.apache.org/dist/spark/spark-2.1.1/spark-2.1.1-bin-hadoop2.7.tgz -C /usr/local/src
wget https://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.tgz -C /usr/local/src

tar -zxvf spark-2.1.1-bin-hadoop2.7.tgz
tar -zxvf scala-2.11.8.tgz

mv spark-2.1.1-bin-hadoop2.7 /usr/local/spark
mv scala-2.11.8 /usr/local/scala

修改配置文件：

cd /usr/local/spark/conf
vim spark-env.sh

export SCALA_HOME=/usr/local/scala
export JAVA_HOME=/usr/local/jdk1.8.0_181
export HADOOP_HOME=/usr/local/hadoop
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
SPARK_MASTER_IP=master
SPARK_LOCAL_DIRS=/usr/local/spark
SPARK_DRIVER_MEMORY=1G

vim slaves

slave1
salve2

配置环境变量：

#Master slave1 slave2

vim ~/.bashrc
SPARK_HOME=/usr/local/spark
PATH=$PATH:$SPARK_HOME/bin

#刷新环境变量
source ~/.bashrc

拷贝安装包：

scp -r /usr/local/spark root@slave1:/usr/local/spark
