2.安装scala
下载路径： https://downloads.lightbend.com/scala/2.12.8/scala-2.12.8.tgz scala-2.12.8.tgz
把下载包上传解压
tar -zxvf scala-2.12.8.tgz
rm -rf scala-2.12.8.tgz
配置环境变量
vi /etc/profile
export SCALA_HOME=/usr/local/scala-2.12.8
export PATH=$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin
复制到其他节点：
scp -r scala-2.12.8 192.168.0.109:/usr/local/
scp -r scala-2.12.8 192.168.0.110:/usr/local/
scp /etc/profile 192.168.0.109:/etc/
scp /etc/profile 192.168.0.110:/etc/
使环境变量生效：source /etc/profile
验证：scala -version

cd /usr/local/
tar -zxvf spark-2.4.5-bin-hadoop2.7.tgz
cd /usr/local/spark-2.4.5-bin-hadoop2.7/conf/ #进入spark配置目录
mv spark-env.sh.template spark-env.sh #从配置模板复制
vi spark-env.sh #添加配置内容
