apache错误日志如下：
[Mon May 16 10:02:30 2011] [alert] [client 127.0.0.1] D:/wamp/www/Think/.htaccess: Invalid command ‘RewriteEngine’, perhaps misspelled or defined by a module not included in the server configuration

解决1：
1. 打开 httpd.conf
2.找到 mod_rewrite.so 行,将前面的注释打开(即删掉前面的’#’符号)。
3.关闭httpd.conf,重启apache服务器即可。

解决2：
httpd.conf 中找到你网站目录对应的Directory 行,将其中的 RewriteEngine 项设置为 ‘ALL’。
