How to install Java SDK on CentOS?

Question

I have CentOS 5, but I don't know the steps to install Java SDK on Linux.

Where to download the RPM file and what can I do next to fully install that?

Then I need to install Tomcat.

Or is there any ready-made package for all?

Answer 1

The following command will return a list of all packages directly related to Java. They will be in the format of java-<version>.

$ yum search java | grep 'java-'

If there are no available packages, then you may need to download a new repository to search through. I suggest taking a look at Dag Wieers' repo. After downloading it, try the above command again.

You will see at least one version of Java packages available for download. Depending on when you read this, the lastest available version may be different.

java-1.7.0-openjdk.x86_64

The above package alone will only install JRE. To also install javac and JDK, the following command will do the trick:

$ yum install java-1.7.0-openjdk*

These packages will be installing (as well as their dependencies):

java-1.7.0-openjdk.x86_64
java-1.7.0-openjdk-accessibility.x86_64
java-1.7.0-openjdk-demo.x86_64
java-1.7.0-openjdk-devel.x86_64
java-1.7.0-openjdk-headless.x86_64
java-1.7.0-openjdk-javadoc.noarch
java-1.7.0-openjdk-src.x86_64
