Setup Play Framework and TypeSafe on centOS

I'm going to setup simple project based on Play Framework together with Cassandra on two centOS servers.

I'm going to do 3 steps during that process:

1. Install Java
2. Install Typesafe activator
3. Create test project.

Installing Java

//1. go to opt folder
cd /opt

//2. download java
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz"

//3. extract java archive
tar xzf jdk-8u60-linux-x64.tar.gz

//4. installing java
cd /opt/jdk1.8.0_60/
alternatives --install /usr/bin/java java /opt/jdk1.8.0_60/bin/java 2
alternatives --config java

//5. recommended options: setup javac and jar
alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_60/bin/jar 2
alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_60/bin/javac 2
alternatives --set jar /opt/jdk1.8.0_60/bin/jar
alternatives --set javac /opt/jdk1.8.0_60/bin/javac

//6. setup variables so we can access java from everywhere
export JAVA_HOME=/opt/jdk1.8.0_60
export JRE_HOME=/opt/jdk1.8.0_60/jre
export PATH=$PATH:/opt/jdk1.8.0_60/bin:/opt/jdk1.8.0_60/jre/bin

//7. checking java version
java -version

//8. delete java archive
rm jdk-8u60-linux-x64.tar.gz

Installing Play Framework / TypeSafe

Example is about current version, which is 1.3.6

//1. go to tmp folder and download typesafe activator
cd /tmp
wget https://downloads.typesafe.com/typesafe-activator/1.3.6/typesafe-activator-1.3.6.zip

//2. unzip and move to opt folder
unzip typesafe-activator-1.3.6.zip
mv activator-dist-1.3.6 /opt

//3. delete zip file, we do not need it anymore
rm typesafe-activator-1.3.6.zip

//4. create soft symbolic link from /opt/activator-dist-1.3.6/activator to /usr/local/sbin/activator
ln -s /opt/activator-dist-1.3.6/activator /usr/local/sbin/activator

//5. set variables so we can use activator from everywhere
export PATH=/usr/local/sbin/activator:$PATH

Create helloworld project

Time to create our first project. Play Framework provides many templates, we are going to use play-java (it has already web interface and some code, so we can discover it).

//1. create folder www in /var (we are going to keep projects there).
cd /var
mkdir www
cd www

//2. have a look on current templates
activator list-templates

//3. create a new project based on play-java template
activator new helloworld play-java

//4. go into newly created project and run it
cd helloworld
activator run

If activator run properly, you should see something like this:

Now you are ready to open project in browser. Type 127.0.0.1:900 and boooom, we have it ready!

I'm going to play with centOS little bit more (before I start to look on code). I already have some minor issues I want to optimise.
