Scala是一门多范式的编程语言，一种类似java的编程语言,设计初衷是实现可伸缩的语言 、并集成面向对象和函数式变成的各种特性。这里为了学习spark特地配置了scala.
1、下载scala安装包：
http://www.scala-lang.org/download
选择最新的安装包下载，进行保存；
2、解压安装包到自己的目录，我解压在了opt目录下：
root@ubuntu:/opt# mkdir ./scala
root@ubuntu:/opt/scala# tar zxvf ../../home/parry/Downloads/scala-2.11.7.tgz
3、配置环境变量:
打开profilr:
root@ubuntu:/opt/scala/scala-2.11.7# gedit /etc/profile
在最后添加配置：
#SCALA setting
export SCALA_HOME=/opt/scala/scala-2.11.7（这里是上面的解压路径）
export PATH=#SCALA_HOME/bin;$PATH
保存退出
4、安装scala:
（1）输入scala
root@ubuntu:/opt/scala/scala-2.11.7# scala
提示还未安装
The program 'scala' is currently not installed. You can install it by typing:
apt-get install scala
根基提示输入apt-get install scala进行安装
root@ubuntu:/opt/scala/scala-2.11.7# apt-get install scala
提示下载更新和资源包：这里根据提示输入Y就可以；等到下载完成
1 upgraded, 28 newly installed, 0 to remove and 250 not upgraded.
Need to get 64.1 MB/64.4 MB of archives.
After this operation, 98.6 MB of additional disk space will be used.
Do you want to continue? [Y/n] Y
（2）输入scala -version 产看scala版本信息：
root@ubuntu:/opt/scala/scala-2.11.7# scala -version
Scala code runner version 2.9.2 -- Copyright 2002-2011, LAMP/EPFL
这里scala安装完成。
5、scala测试：
（1）输入scala进入scala,输入
root@ubuntu:/opt/scala/scala-2.11.7# scala
Welcome to Scala version 2.9.2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_79).
Type in expressions to have them evaluated.
Type :help for more information.
（2）输入1+1进行计算
scala> 1+1
res0: Int = 2
scala>
