配置环境变量

[root@centos01 java]# vim /etc/profile

 

向文件里面(最下面) 追加以下内容

export SCALA_HOME=/usr/local/scala/scala-2.12.6
export PATH=$PATH:$SCALA_HOME/bin

编辑完后按左上角的 ESC键，然后 wq 保存。

 

使配置文件生效：source /etc/profile

[root@centos01 centos01]# source /etc/profile

 

测试配置是否成功

[root@centos01 centos01]# echo $PATH
