1、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/mod_encoding-20021209.tar.gz
# wget http://webdav.todo.gr.jp/download/experimental/mod_encoding.c.apache2.20040616
# tar zxfv mod_encoding-20021209.tar.gz
# cp mod_encoding.c.apache2.20020616 mod_encoding-20021209/mod_encoding.c

2、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
# make install
完成上面操作后，iconv_hook相关so文件放到/usr/local/lib下面。
打开/etc/ld.so.conf文件，添加一行指向iconv_book的所在路径，即”/usr/local/lib”

# vi /etc/ld.so.conf
添加/usr/local/lib

# ldconfig

3、 mod_encoding模块的编译
进入mod_encoding-20021209.tar.gz的解压目录，即mod_encoding-20021209
–with-iconv-hook[=DIR]  use iconv.h from iconv_hook in DIR
(default is /usr/local/include/iconv_hook)

# ./configure –with-apxs=/usr/sbin/apxs –with-iconv-hook=/usr/local/include
# make

我在执行make命令编译时，会报如下错误：
/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 -D_LARGEFILE64_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] Error 1

原因很明显，是regex.h未包含进来，解决办法也很简单，用vi打开mod_encoding.c，
在#include <httpd.h>那一段的前面加上如下一行：
#include <regex.h>

再编译应该就可以通过了

#ls -l mod_encoding.o  查看是否已经生成了mod_encoding.o文件，如果是，则make成功继续下边的操作。
# gcc -shared -o mod_encoding.so mod_encoding.o -Wc,-Wall -L/usr/local/lib -Llib -liconv_hook

生成mod_encoding.so文件，将该文件拷贝到你的模块存放目录,一般为${APACHE_HOME}/modules/
# cp mod_encoding.so /usr/local/apache/modules/mod_encoding.so

4、 httpd.confd的設定
这个是我的设置文件

LoadModule headers_module modules/mod_headers.so
LoadModule encoding_module modules/mod_encoding.so
<IfModule mod_headers.c>
Header add MS-Author-Via “DAV”
</IfModule>
<IfModule mod_encoding.c>
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
</IfModule>
