Installing Scala

If you have the Scala .tar file (for example, scala-2.12.6.tgz), then copy it to an AWS EC2 Linux instance at any location (for example, /opt):

• You can also download the latest binary .tar.gz file from http://www.scala-lang.org/download/all.html
• You can download 2.12.6 from the following location: https://downloads.lightbend.com/scala/2.12.6/scala-2.12.6.tgz

Follow these steps to install Scala 2.12.6 on your Linux VM:

1. Go to the location where you copied the Scala software package and uncompress it:

cd /opt
tar -xzvf scala-2.12.6.tgz

1. Set the environment variable in .bash_profile, as follows:

nano ~/.bash_profile

1. Add the following lines to the end of the file:

export SCALA_HOME=/opt/scala-2.12.6
export PATH=$PATH:$SCALA_HOME/bin

1. Run the following command to update the environment variables in the current session:

source ~/.bash_profile

1. Check for a Scala installation by running the following command:

scala -version
