新安装的CentOS没有默认没有装语言支持（Language Support），因此很不方面。

终于发现了有效的方法：

su root

yum install "@Chinese Support"

exit

然后设置Input Methord即可。

最后一步：logout，注意是注销，然后再次登录此用户。

Install Language support in CentOS 5 or Red Hat Enterprise Linux
by Vivek Gite on June 15, 2007 · 8 comments

Q. How do I install Languages in Linux after installation? I don’t have any language specific support installed but need to install the same. I’m using both RHEL 5 and CentOS 5.

A. Yellow dog Updater, Modified, a package manager for RPM-compatible Linux systems such as CentoS 5/Fedora 7 and RHEL 5. Yum's repository system is quickly becoming the standard for RPM-based repositories.

If the languages were not installed during the installation, the same can be installed by YUM command. Use following command to install Hindi and Chinese support.

# yum groupinstall {LANGUAGE-support}

# yum install "@Hindi Support"
# yum install "@Chinese Support"

Use yum grouplist list available groups and languages.
