centos7 Scala安装

使用wget下载Scala压缩包

[root@master ~]# wget https://downloads.lightbend.com/scala/2.12.11/scala-2.12.11.tgz

解压Scala压缩包到/usr/local/src/

[root@master ~]# tar -zxvf scala-2.12.11.tgz -C /usr/local/src/

将解压文件夹改名为scala

[root@master ~]# mv /usr/local/src/scala-2.12.11/ /usr/local/src/scala

配置Scala的环境变量

vim /etc/profile

export SCALA_HOME=/usr/local/src/scala
export PATH=$PATH:$SCALA_HOME/bin

使环境变量生效

[root@master ~]# source /etc/profile

进入scala

[root@master ~]# scala
