chmod 755 /usr/local/apache/modules/mod_rewrite.so
[activating module `rewrite' in /usr/local/apache/conf/httpd.conf]

[root@66 bin]# ./apachectl restart

如果没有什么错误的话，会在apache/modules目录中编译出一个mod_rewrite.so文件。
并会在自动在httpd.conf中加载，如果没有自动加载，手工修改httpd.conf文件
vi /usr/local/apache/conf/httpd.conf
LoadModule rewrite_module modules/mod_rewrite.so
