Linux系统下scala安装详解

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。
