故障描述：外网有一台apache服务器提供软件给客户下载，因为很多软件名是带有中文的，所以下载的时候失败，临时的解决方案是将中文名修改为一个英文名就OK了，但是这只是一时的解决步骤，最终的方案就是让apache支持中文软件名文件下载。
环境描述：
系统：红帽4.8 apache版本:2.2.11
不知道apache版本的哥们可以用如下命令参考：
/usr/local/apache2/bin/apachectl -v
1、先确认mod_headers已经静态编译到apache中。
grep headers /usr/local/apache2/conf/httpd.conf
如果没有输出，那么你没有编译mod_headers到apache
解决办法：
解决办法：
下载和你apache版本相对应的源码包，下载后解压到当前目录
tar zxvf httpd-2.2.11.tar.gz
cd httpd-2.2.11/modules/metadata
/usr/local/apache2/bin/apxs -i -a -c mod_headers.c
编译完成之后，再确认一下httpd.conf是否有mod_headers.so文件，如果有则说明已经加载成功！
grep headers /usr/local/apache2/conf/httpd.conf
LoadModule headers_module modules/mod_headers.so
LoadModule headers_module modules/mod_headers.so
2、下载相关文件并解压
WebDAV Resources JP有Apache2对应的mod_encoding的最新版本下载
wget
http://webdav.todo.gr.jp/download/experimental/mod_encoding.c.apache2.20040616
wget http://webdav.todo.gr.jp/download/mod_encoding-20021209.tar.gz
tar zxfv mod_encoding-20021209.tar.gz
cp mod_encoding.c.apache2.20040616 mod_encoding-20021209/mod_encoding.c
3、iconv_hook编译和安装，安装mod_encoding前首先需要安装iconv_hook。
wget http://webdav.todo.gr.jp/download/mod_encoding-20021209.tar.gz
tar zxfv mod_encoding-20021209.tar.gz
cp mod_encoding.c.apache2.20040616 mod_encoding-20021209/mod_encoding.c
3、iconv_hook编译和安装，安装mod_encoding前首先需要安装iconv_hook。
cd mod_encoding-20021209/lib
./configure
make
mke install
完成上面操作后，iconv_hook相关的so文件放到/usr/local/lib下面。
要系统能够搜索到该so文件，需要让他自动加载
vi /etc/ld.so.conf
增加如下内容：
/usr/local/lib
增加完后执行如下命令：
PATH="$PATH:/sbin"
ldconfig
3、mod_encoding模块的编译安装
cd mod_encoding-20021209
./configure --with-apxs=/usr/local/apache2/bin/apxs --with-iconv-hook=/usr/local/include
make
make
如果make报错如下的话：
/usr/local/apache2/bin/apxs -c -I/usr/local/include -liconv_hook mod_encoding.c
/usr/local/apache2/build/libtool --silent --mode=compile gcc -prefer-pic -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -g -O2 -pthread -I/usr/local/apache2/include -I/usr/local/apache2/include -I/usr/local/apache2/include -I/usr/local/include -c -o mod_encoding.lo mod_encoding.c && touch mod_encoding.slo

make: *** [mod_encoding.so] 错误 1
解决该错误很简单，打开mod_encoding.c文件

make: *** [mod_encoding.so] 错误 1
解决该错误很简单，打开mod_encoding.c文件
找到如下内容：
#include
在上述内容中增加如下内容：
#include
再重新./configure，make即可！如果还不行那上网查相关资料吧！
查看是否在当前目录下是否生成了mod_encoding.o文件，生成后继续执行如下命令：
gcc -shared -o mod_encoding.so mod_encoding.o -Wc,-Wall -L/usr/local/lib -Llib -liconv_hook
执行上述命令后不会有任何输出提示，再次确认是否生成了mod_encoding.so文件，并将该文件拷贝到你自己的apache的模块存放目录，我的就是/usr/local/apache2/modules

cp mod_encoding.so /usr/local/apache2/modules/mod_encoding.so
4、httpd.conf文件增加如下内容是为了更好的支持中文软件名称：
4、httpd.conf文件增加如下内容是为了更好的支持中文软件名称：
LoadModule encoding_module modules/mod_encoding.so
Header add MS-Author-Via "DAV"
EncodingEngine on
NormalizeUsername on
SetServerEncoding GBK
DefaultClientEncoding UTF-8 GBK GB2312
AddClientEncoding "(Microsoft .* DAV $)" UTF-8 GBK GB2312
AddClientEncoding "Microsoft .* DAV" UTF-8 GBK GB2312
AddClientEncoding "Microsoft-WebDAV*" UTF-8 GBK GB2312
5、重新启动apache，将带有中文名称的软件放到你的web服务器的发布目录下测试是否可以正常下载？
