install_scala_centos.sh

export SCALA_VERSION=scala-2.11.5
sudo wget http://www.scala-lang.org/files/archive/${SCALA_VERSION}.tgz
sudo echo "SCALA_HOME=/usr/local/scala/scala-2.11.5" > /etc/profile.d/scala.sh
sudo echo 'export SCALA_HOME' >> /etc/profile.d/scala.sh
sudo mkdir -p /usr/local/scala

cd /usr/local/scala/
sudo -s tar xvf $SCALA_VERSION.tgz
sudo rm -f $SCALA_VERSION.tgz
sudo chown -R root:root /usr/local/scala

Thanks, helped a lot
but why the change back to "sudo echo "SCALA_HOME=/usr/local/scala/scala-2.11.5" > /etc/profile.d/scala.sh" ?

There is a simpler way exists:

wget http://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.rpm
sudo yum localinstall -y scala-2.11.8.rpm

also this way:

  yum:
    name: http://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.rpm
    state: present
