How to input Korean, Japanese and Chinese on Centos / RHEL

There seems to be a number of RHEL packages that support far east Asian language support like Korean, Japanese or Chinese. None of the package description explains how to install them, and configure to work with different languages so here is one method I found working.

1. Before you can install Linux packages on your system, you'll have to login as a 'root' user either by 'su' or 'login' command.

2. Install required Linux packages.

# yum groupinstall "Korean Support"

or 

# yum groupinstall "Japanese Support"

or

# yum groupinstall "Chinese Support"

3. Once you install groupware that supports Asian lagnuages, you'll need to configure it to work with a KDE or any X display system you work in. Go to System -> Preferences -> Input Methods. A "IM Chooser" window opens up that will allow you to configure Input Method on the RHEL system.

4. Click Input Method Preferences.

5. Click on the Input Method tab, and add one or more language that you would like to use.

6. Click on the General Tab. Make note of Enable/Disable key sequence, and Next Input Method keyboard shortcut that will switch between the input methods.
