1、下载apache源码包，解压并查找到mod_rewrite.c文件

      tar -zxvf httpd-2.2.27.tar.gz

      cd httpd-2.2.27         

[root@localhost httpd-2.2.27]# find . -name mod_rewrite.c

./modules/mappers/mod_rewrite.c                         

[root@localhost httpd-2.2.27]# cd ./modules/mappers/

[root@localhost mappers]# /www/wdlinux/apache/bin/apxs -c mod_rewrite.c

/www/wdlinux/httpd-2.2.22/build/libtool --silent --mode=compile gcc -prefer-pic   -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -g -O2 -pthread -I/www/wdlinux/httpd-2.2.22/include  -I/www/wdlinux/httpd-2.2.22/include   -I/www/wdlinux/httpd-2.2.22/include   -c -o mod_rewrite.lo mod_rewrite.c && touch mod_rewrite.slo                                                                                     

/www/wdlinux/httpd-2.2.22/build/libtool --silent --mode=link gcc -o mod_rewrite.la  -rpath /www/wdlinux/httpd-2.2.22/modules -module -avoid-version    mod_rewrite.lo     

[root@localhost mappers]# /www/wdlinux/apache/bin/apxs -i -a -n mod_rewrite mod_rewrite.la

[root@localhost mappers]# ls /www/wdlinux/httpd-2.2.22/modules/

[root@localhost mappers]# ls /www/wdlinux/apache/modules/

httpd.exp  libphp5.so  mod_rewrite.so  mod_rpaf-2.0.so

可以看到modules文件夹下出现了mod_rewrite.so文件

但后来在启动重启mysql数据库时，发现wdcp已经内建了mod_rewrite模块，不需要单独编译
