解决Redhat中文网页显示乱码的方法

系统：英文版的Redhat企业版
症状：英文显示没问题；中文输入法也没问题；中文网页显示为乱码，不管是用GB18030还是2312
解决：安装fonts-chinese-3.02-9.6.el5.

此时相关如下：
[root@localhost ~]# rpm -qa | grep fonts- | wc -l
14
[root@localhost ~]# rpm -qa | grep fonts-
bitmap-fonts-0.3-5.1.1
xorg-x11-fonts-misc-7.1-2.1.el5
fonts-chinese-3.02-9.6.el5
xorg-x11-fonts-base-7.1-2.1.el5
xorg-x11-fonts-75dpi-7.1-2.1.el5
urw-fonts-2.3-6.1.1
xorg-x11-fonts-100dpi-7.1-2.1.el5
bitstream-vera-fonts-1.10-7
ghostscript-fonts-5.50-13.1.1

dejavu-lgc-fonts-2.10-1
xorg-x11-fonts-truetype-7.1-2.1.el5
[root@localhost ~]# cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
[root@localhost ~]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
[root@localhost ~]#

网上提供的消除中文乱码的方法如下，只是一种治标的方法，应该是先查看有没有相关的字体包已经安装，再考虑更改如下设置：

将i18n内容改为

LANG="zh_CN.GB18030"
LANGUAGE="zh_CN.GB18030:zh_CN.GB2312:zh_CN"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="lat0-sun16"

LC_MESSAGES目录中是MO (Machine Object) files，可以理解为中文库文件，示例如下：

定义区域语言的配置文件位置：

以前还有/usr/share/i18n/repertoiremaps目录和其中相关的配置文件，现在已经不用。

[root@localhost i18n]# man localedef 用来生成区域设置

修改系统编码变换设置，告诉系统如何将汉字编码转换为系统内部码:

[root@localhost ~]# locate gconv-modules //查找配置文件位置
/usr/lib/gconv/gconv-modules
/usr/lib/gconv/gconv-modules.cache


ＸＦｒｅｅ８６设置:

[root@localhost ~]# locate locale.dir
/usr/share/X11/locale/locale.dir

环境变量的设置:

[root@localhost ~]# echo $LANG //这是我电脑上的配置
en_US.UTF-8
