由于某些原因系统安装时未安装中文支持，导致后续应用出现中文方块乱码现象，解决方法很简单，当然不是重装，只需以下三步即可搞定。
1、安装中文包：
#yum -y groupinstallchinese-support安装所有与中文支持相关的包
2、修改字符编码配置文件
# vi/etc/sysconfig/i18n
修改后内容如下：
LANG="zh_CN.UTF-8"
SUPPORTED="zh_CN:zh:en_US.UTF-8:en_US:en:zh_CN.GB18030"
SYSFONT="latarcyrheb-sun16"
3、最后重启服务器：
#reboot
具体过程如下：
[root@sun isolinux]# yum -yinstall font
