本文详细介绍了在Linux系统中安装Scala的过程，首先需要安装Java JDK，然后下载Scala安装包，分别进行解压和配置环境变量，最后通过执行`scala`命令验证安装成功，开始Scala的学习之旅。

  由于公司业务开展的原因，需要用到多维度分析，所以打算从scala开始，以后会写一系列scala的学习笔记，做一下记录，同时给他人方便。 

  安装scala，需先安装Java的jdk。 

 
 步骤一、下载jdk安装包 

  点击下面链接，选择一个jdk版本，我选择的是 jdk-8u111-linux-x64.tar.gz 

 
 http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 

 
 步骤二、下载scala安装包 

  点击下面链接，选择一个scala版本，我选择的是 scala-2.11.6.tgz 

 
 http://www.scala-lang.org/download/ 

 
 步骤三、安装jdk 

  1、将安装包jdk-8u111-linux-x64.tar.gz放置到usr下预先创建好的目录java中，解压之。 

  2、在文件/etc/profile底部添加环境变量 

  #set java 

  export JAVA_HOME=/usr/java/jdk1.8.0_111 

  export PATH=$PATH:$JAVA_HOME/bin 

  export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 

  3、退出文件执行命令sync同步一下 

 
 步骤四、安装scala 

  1、将安装包scala-2.11.6.tgz放置到/usr下预先创建的scala目录中，解压之。 

  2、在文件/etc/profile底部添加环境变量 

  #set scala 

  export SCALA_HOME=/usr/scala/scala-2.11.6 

  export PATH=$PATH:$SCALA_HOME/bin 

  3、退出文件执行命令sync同步一下 

 
 步骤五、检测 

  执行scala命令如果有如下提示，则表示scala安装完成，就可愉快开启scala学习之路了。
